In Hong Kong, studying Geography is categorized as useless because the culture of British Meritocracy here stresses the achievements of business studies. However, if going back to Mainland China or having a travel to either the US or Australia, you will find that your knowledge on Geography is very useful because the ruling regimes there greatly acknowledge the elites who graduated from the field of Agricultural Research.
Cynical people without a longsighted vision use to criticize that my Master Degree of China Studies is something too abstract because they use to be British-Hong Kong colonial debrises. However, they never know that, during my two-year research life in this academic department, I did render some challenging topics including the river-management and dam-construction issues of Mainland China. Just like what Mr. Tung Chee-hwa said in 2014 during a press conference: "Our country is rapidly growing up as a strong economic power. To my greatest disappointment, Hong Kong people still lack a long-sighted vision, and they are unwilling to change their perceptions." So, such group of people will never understand the scholastic efforts I have input in this holistic social-science learning experience.

A REVIEW ARTICLE ON IMPACT OF URBANIZATION ON HYDROLOGICAL PARAMETERS IAEME Publication
As longas human being continues to exists,urbanization continues. Urbanizationhasa direct effect on environment which in turn effects the variations in hydrology. It may results from changes inthe land use pattern to built-up areas resulting in runoff which ultimately leads to flood. Most of the studies revealed thatland use pattern has drastically changed in whichthe builtup area increases year after year.The land use land cover changes can be identified using GIS. Many researchers have found that urbanization has an impact on hydrological parameters such as runoff volume, discharge in drains, infiltration, interception, evapotranspiration etc. An attempt has been made to consolidate the review of literature related to impact of urbanization on hydrological parameters.
The document discusses the effects of constructing dams, including both environmental impacts and impacts on displaced human populations. Dams interrupt natural water cycles, cause erosion, change river temperatures, and stop fish migration. When constructing the Bargi Dam in India, over 5,000 families were displaced, but the government initially failed to properly rehabilitate the affected people. After years of protests, the government eventually worked with the displaced peoples' union to provide compensation and rehabilitation. The Three Gorges Dam in China displaced over 1 million people and damaged cultural and archaeological sites. Globally, an estimated 40-80 million people have been displaced by dam construction without adequate rehabilitation.
The document discusses various topics related to groundwater and surface water systems. It explains that groundwater and surface water are connected, with pumping wells able to cause interference between cones of depression. It notes that extraction should not exceed recharge to avoid water mining and subsidence, and that recharge zones need protection. The hyporheic zone of water exchange between surface and groundwater is also described. Rainwater harvesting and the water cycle are briefly covered.
Freshwater wetlands are ecosystems characterized by the transition between freshwater and land. They have a unique structure defined by the hydrology of water flow, including properties like precipitation, depth, and duration of flooding. Key functions of freshwater wetlands include transferring energy through the food chain, preventing flooding, and storing water. Ecosystem services provided by wetlands fall into categories like provisioning of water, regulating of climate and water quality, supporting of nutrient cycles, and cultural benefits like recreation.
This document provides an overview of water resources and the global water cycle. It discusses how water is distributed globally between oceans, ice caps, groundwater, and other stores. Groundwater flows through aquifers and is essential for drinking, agriculture, and industry. However, human activities like overuse, pollution, and climate change are putting stress on freshwater supplies in many regions. The document outlines the water cycle between the atmosphere, oceans, and land, and how climate change may impact these processes.

Impact of landuse development on a highland freshwater lake.leona48
Intensive landuse development always be accused as the main factor to cause increase in generation of pollutants, taking the runoff as the transport medium. A study to find the relationship of landuse development and seasonal water quality changes in a highland lake, Ringlet Lake, Cameron Highland, Malaysia proves that as the percentage of watershed cleared area rised, the degree of water quality deterioration tends to increase accordingly. The study found that most of the parameter analyzed in both seasons shows that Ringlet Lake fell into Class III in the Water Quality Index, which need extensive treatment for domestic uses. The high percentage of cleared area as indicated by individual type of landuse leads to produce polluted runoff which ended up into the nearest river network, Bertam and Ringlet River and eventually entered the lake. In highland areas, a basin management of a water body should be more refined and specific in order to address focus of concerns in lake ecosytem health and quality impairment issues.

Dams can have significant ecological impacts:
1) They obstruct fish migration and disrupt populations.
2) Water quality is reduced as still water gathers pollution and alters temperatures affecting oxygen and chemical reactions.
3) Sediment builds up behind dams, raising water levels and putting pressure on dam walls which could eventually burst, flooding towns.
The document discusses the impacts of large dams on the environment and climate, using the Tehri Dam in Uttarakhand, India as a case study. It summarizes that the Tehri Dam provides benefits like hydroelectric power, flood control, irrigation, and tourism, but also resulted in mass displacement of people, deforestation, and impacts on biodiversity. Mitigation efforts were undertaken for afforestation, erosion control, and protecting displaced communities and the environment.
This document discusses how global climate change and human activities are altering coastal ecosystems by intensifying eutrophication. Climate change is causing detrimental effects through changes in temperature, salinity, winds, storms, and sea levels. These changes increase stratification in water columns and the vulnerability of coastal habitats. Additionally, human industrialization and farming are producing large quantities of reactive nitrogen and phosphorus that promote eutrophication when they reach coastal waters through rivers and runoff. The Mississippi River watershed example shows how nutrient overloading from landscape changes can continuously expose large coastal ecosystems to eutrophication. There is a need to reduce excess nutrient loads to prevent further water quality declines.
Impact of Building Dam on River Ecosystem and Its Preventive Measures╚»Śăńğĩť Βăńĩķ«╝
The document discusses the environmental impacts of dam construction on river ecosystems. It states that dams can result in physical, chemical, and biological changes to ecosystems upstream, in the reservoir, and downstream. Specific impacts mentioned include blocking fish migration, changes in sediment flow, flooding of natural habitats, and species changes from altered flooding patterns. The document also provides a case study on the impacts of the Farakka Barrage on the Ganges River in Bangladesh, such as reduced sediment and water flows. It notes some proposed solutions like building additional reservoirs and canals. The conclusion discusses how dams have both benefits and detriments and calls for further studying impacts and improving engineering to reduce negative effects.
This document discusses salinity prevention and sea water intrusion. It begins by introducing the topic and defining salinity and sea water intrusion. The main causes of sea water intrusion are then explained as heavy groundwater extraction, canals and drainage networks, and the higher density of seawater compared to freshwater. Effects of salinity include negative impacts on agriculture, water quality, ecology, and human health. Preventive measures discussed include barriers, recharge techniques like check dams and recharge wells, and government projects in Gujarat including construction of check dams and reservoirs.
This document discusses dams and their environmental and social impacts. It begins by defining dams and explaining their purposes, which include irrigation, flood control, hydropower, and navigation. It then describes the main types of dams and discusses their environmental performance, noting impacts on terrestrial and aquatic ecosystems from habitat loss and changes to natural flow regimes. Socially, dams can displace large populations and disrupt livelihoods when people are resettled or downstream access to resources is reduced. Planning for dams often undercounts affected people and resettlement efforts are frequently inadequate.
The document discusses methods of flood control and river management. It describes various causes of flooding such as heavy rain, urbanization, dam collapse, and snow melt. Common flood control techniques include building dams and pumping stations, barriers, altering river channels, and controlling land use near rivers. The Mississippi and Nile Rivers are discussed as examples, noting large levee systems on the Mississippi and the Aswan High Dam on the Nile, which was built to control flooding but caused environmental issues.
This document discusses salinity prevention in coastal areas of Gujarat, India. It was submitted by 4 students as a project report for their Design Engineering course. The document outlines the objectives of understanding and preventing sea water intrusion. It describes how sea water intrusion occurs naturally due to the higher density of saltwater but is exacerbated by groundwater extraction and canal construction. This leads to salinity which affects agriculture, water quality, ecology, infrastructure and human health. The government of Gujarat has undertaken various projects to address salinity issues in coastal regions.
This document summarizes the salinity risk assessment in Bangladesh. It finds that salinity is a major issue for the coastal region of Bangladesh, affecting over 35 million people in 19 districts. Salinity has increased the amount of affected land area from 8,330 square km in 1973 to 10,560 square km in 2009. This salinity is damaging agriculture and increasing costs of crop production. The government of Bangladesh is taking steps to address salinity through projects, but some projects have failed or been completed slowly. Overall salinity poses serious economic and infrastructure risks for Bangladesh.
Freshwater Ecosystems include standing water or lentic such as lakes, ponds, marshes and wet lands, and the flowing water or lotic such as spring, streams and rivers. This ecosystem is normally of very low salinity usually between 15 to 30 ppt. They are highly variable and their characteristics depend upon the surrounding geology, land use and pollution levels.
Ecological impacts of dams and water diversionsMrJewett
Dams impact rivers and their ecosystems in several ways. They block migratory fish from accessing spawning habitats upstream, as fish ladders are often ineffective. This disrupts fish life cycles and populations. Dams also alter sediment and water flow, affecting water quality, aquatic habitats, and nutrient levels downstream. Large dams significantly change river landscapes and environments, sometimes flooding important habitats and destroying cultural heritage sites.
Most of Earth's water is found in oceans (97%), while only 3% is freshwater. The majority of freshwater is frozen in ice sheets and glaciers in polar regions. Underground sources like aquifers provide important fresh water through springs and wells. Rivers play a key role in the water cycle, transporting water from higher elevations through three stages - youth, maturity, and old age - before emptying into oceans.
This document is a research paper that explores the impacts of traditional stormwater management versus green infrastructure on the Chesapeake Bay watershed. It summarizes that water quality data shows lower nitrogen levels in Gunston Cove, which receives runoff from Fairfax County that uses green infrastructure, compared to the Upper Potomac River, which receives runoff from Montgomery County that uses traditional stormwater management. Fairfax County has implemented several green stormwater initiatives while Montgomery County was sued for not meeting water quality standards. The document provides background on threats to the Chesapeake Bay ecosystem and reviews literature on the water quality and stormwater management approaches of the different watersheds.
Water storage for secure water supply, Ho Chi Minh CityHanna Stahlberg
The document discusses potential solutions for securing Ho Chi Minh City's water supply in the face of increasing salinity intrusion issues. It summarizes workshops that explored both short-term and long-term options. Short-term solutions included mixing water from alternative intake points with existing supplies or building small storage reservoirs. Long-term solutions involved larger infrastructure like canals, pipelines, or reservoir systems that could provide intake selectivity and storage capacity of 6-90 days to cope with salinity fluctuations. The workshops aimed to identify adaptive measures that balance water supply reliability, flood control, nature conservation and recreation.
This document discusses Great Lakes ice forecasts and climate research. It notes that ice affects many aspects of the Great Lakes community, including under-ice physics, ship navigation, winter recreation, lake effect snow, evaporation, and water levels. It then summarizes the Nationwide Operational Forecasting System and Great Lakes Coastal Forecasting System, which provide nowcasts and forecasts out to 30 and 120 hours using physical and ice models. Finally, it lists applications of ice forecasts such as guidance for ship navigation, ice jams, consequences of extreme winters, lake heat content, evaporation, currents, and water level prediction.

Assessment Of Lake Water Quality And Eutrophication Risk In An Agricultural I...Amy Cernava
This document discusses a study assessing the water quality and risk of eutrophication in Chagan Lake, an agricultural lake in Northeast China. Field investigations and statistical analyses were conducted to examine water quality indicators like nutrients and non-nutrients across different locations and seasons. The results showed that the lake water was hyper-eutrophic in summer, with high levels of total nitrogen, total phosphorus, and eutrophication indices. The quality varied spatially, with nutrients being major factors in different regions. Controlling agricultural drainage was identified as crucial for managing the lake's water quality and risks of eutrophication.
Dams provide many benefits like improving quality of life through irrigation, flood control, hydropower, and more. However, they can also negatively impact the environment and human populations. Key impacts include displacing many people worldwide and inadequate compensation, harming terrestrial and aquatic ecosystems by blocking animal migrations and altering natural river flows, and emitting greenhouse gases from reservoirs. While dams provide irrigation and hydropower, their construction often undercounts displaced people and fails to fully resettle them, compromising livelihoods. Cultural heritage sites can also be damaged or lost. Mitigation efforts are often insufficient to address these social and environmental impacts.
This document discusses environmental flow assessments conducted in the Barron River and Mitchell River regions. In the Barron River, which is highly regulated, stable isotope analysis showed that benthic algae are an important carbon source for consumers. Studies examined how algal growth and ecosystem metabolism, as indicators of primary production, are affected by variations in river flow. In the less regulated Mitchell River, the study aimed to better understand natural food web functioning and the importance of dry and wet season production. Results showed external carbon sources mainly support fish communities in the dry season, while local production and connectivity to floodplains and marine areas boost productivity significantly in the wet season.
An Evaluation of Heavy Metals Concentration in the Choba Section of the New ...Scientific Review SR
Assessment of heavy metals concentration in water and sediments of the Choba section of the New
Calabar River, Eastern Niger Delta were carried out. Seven (7) river sediments and twelve (12) surface water
samples were collected for the study. The heavy metals studied were: Mn, Pb, Zn, Fe, Cd, Cr, and Cu for in both
river sediment and surface water. The World Health Organization (WHO) standards were used in evaluating
Pollution Index (PI) of heavy metals in surface water. The Pollution Load Index (PLI) level of river sediments
ranged from 5.12 – 33.26, with only PLI values <1 considered unpolluted. The other samples analyzed revealed
high pollution levels, with Cu, Cr and Mn having moderate to considerable Contamination Factor levels, while
the others were of low levels. For surface water, Pb and Zn had high Pollution Index values, with Pb having PI
values ranging 10 – 211, with considerable contribution of pollutants from anthropogenic activities into the river.
There is urgent need for regular monitoring of the Choba section of the River. The regulatory government agency
responsible for protecting the environment should also pay adequate attention to this stretch of the river to avoid
further contamination.
The document summarizes findings from an environmental study of the Lancang-Mekong Development Plan (LMDP) and the proposed Pak Beng dam project. Key findings include changes to hydrology and sediment flows due to Chinese dams, impacts to aquatic ecology, and identification of environmentally sensitive areas. The study recommends establishing a network of conservation areas along the Mekong River to help mitigate impacts from proposed developments. Specific mitigation strategies are provided for each of three zones studied.
This document summarizes the flood pulse concept (FPC), an ecological model for river-floodplain systems. The FPC proposes that flooding periodically connects rivers to their floodplains, driving nutrient exchange and high primary production. Since the FPC was introduced in 1989, knowledge of floodplain ecology has increased, requiring updates and extensions to the original concept. The document reviews advances in understanding hydrology, biogeochemistry, biodiversity and other areas that have both supported predictions of the FPC and inspired new approaches to studying river-floodplain systems.

The document summarizes water quality monitoring of the Logan, Albert, Pimpama and Coomera River catchments in southeast Queensland over four years. It finds that water quality is generally good in upstream freshwater areas but poorer in estuarine sections and sites near developed areas. Specific problems identified include high nutrients, sediments and bacterial levels impacting recreational use. Ongoing monitoring and wastewater treatment upgrades are occurring to address issues, while individual actions to reduce stormwater pollution are encouraged.
The document summarizes the mission and science-based work of the National Park Service at the Cape Cod National Seashore. It discusses inventorying, monitoring, and research efforts across various natural systems to understand resources, track changes over time, and inform adaptive management. Examples of current and future studies are provided covering topics like salt marsh restoration, water quality, species populations, climate change impacts, and more. The work involves interdisciplinary teams of scientists, technicians, and ecologists.
Human civilizations have long depended on rivers for survival, with early civilizations in regions like Mesopotamia, Egypt, India, and China developing along major river valleys. However, as human populations and activities have increased, they have placed growing stress on rivers through activities like water extraction, waste dumping, and infrastructure development. This has degraded river ecosystems and impacted their ability to provide services. Parameters like water flow, sediment levels, pollution, and biodiversity are used to measure a river's health and the human impacts on it. The case of the Yamuna River in India illustrates how urban and industrial waste dumping can turn a major river highly toxic, reducing it to a local extinction of its natural ecosystems. Experts recommend various
Large scale river restoration programs require bringing science into both planning and implementation. Two successful projects, the Kissimmee River Restoration and Healthy Waterways Initiative in Australia, established rigorous monitoring programs to evaluate outcomes. The California Delta faces challenges of balancing water exports and habitat restoration, requiring an adaptive approach incorporating the best available science. Institutional challenges to large river restoration include uncertainty, the transition from planning to action, effective communication, and integrating synthesized data.
This document provides an overview of groundwater basics and factors influencing groundwater quality and quantity in Taylor County, Wisconsin. It discusses watersheds, wellhead protection, approaches to addressing groundwater issues from both a bottom-up and top-down perspective, and Taylor County's drinking water education and testing program.

This document discusses food chains, food webs, and the impact of human interactions on aquatic ecosystems. It provides examples of biotic and abiotic components of marine ecosystems and describes typical food chains and food webs. Human activities like overfishing, pollution, coastal development, and tourism are negatively impacting marine ecosystems by disturbing food webs, damaging habitats, and accumulating toxins. The document also examines water demand and supply in Bangalore, India, given its population growth. It analyzes Bangalore's water sources and consumption trends, the existing shortfall, and recommends strategies like conservation, wastewater recycling, and groundwater recharge to close the growing gap between demand and supply.
This document discusses the importance of stream restoration practices in implementing the Farm Bill. It notes that streambank erosion now contributes up to 70% of sediment loads in many watersheds across the US, compared to lower levels decades ago. Over 200,000 miles of stream corridors have accelerated streambank erosion. Case studies show how channel incision can increase sediment delivery and negatively impact water quality. Restoring incised streams by rebuilding floodplains and reconnecting channels to their floodplains can help reduce erosion. The document emphasizes the need to prioritize restoration at the greatest sources of erosion and maintain conservation practices.
This document summarizes an analysis of potential wetland and habitat loss in Oregon coastal watersheds due to sea level rise. The analysis used sea level rise scenarios from the IPCC to estimate wetland area loss across 14 watersheds. It found the Lower Columbia, Nehalem, and Umpqua watersheds had the highest relative wetland losses and importance for restoration efforts to mitigate impacts to salmon habitat from predicted sea level rise. Maps and charts visualize wetland loss percentages under different sea level rise scenarios across the watersheds.
- The confined segment of the stream exported water and dissolved organic carbon consistently, while the unconfined segment stored these during high flows and exported them during low flows due to increased water residence times in floodplain water bodies.
- Rates of gross primary productivity and ecosystem respiration were generally lower and less variable at the outflow of the confined segment compared to the outflow of the unconfined segment, and rapidly increased in a floodplain side channel as it disconnected from the main channel.
- The study found that intermittent connectivity between rivers and their floodplains can optimize ecosystem metabolism by allowing storage of resources like dissolved organic carbon during high flows, and utilization of these resources during low flows when water residence times in flood

This document summarizes an integrated assessment of water level variability and coastal bluff erosion in northern Milwaukee County and southern Ozaukee County, Wisconsin. A team of investigators from multiple disciplines studied how rising lake levels since 2014 could impact coastal bluffs. Through interviews and workshops, they explored issues, solutions, and information needs. The project aims to develop policy alternatives to increase bluff resilience and adapt to potential increased lake level variability in the near-term, and increase adoption of these policies and adaptive actions in the mid-term to ultimately strengthen bluff resilience long-term.
This document discusses changing water levels in the Great Lakes. It begins with an introduction and outline. It then covers historical water levels, including their seasonal and interannual variation. The main drivers of water level changes are described as the hydrologic cycle of precipitation, evaporation, runoff and flows between lakes. Projections are discussed for both seasonal and decadal timescales. The conclusions discuss challenges around quantifying data value, using models to replace observations, uncertainty quantification and the ability of projections to offer insights rather than firm predictions.
This document provides an overview of an integrated assessment being conducted to analyze options for adapting to variability in Great Lakes water levels. The assessment will:
1) Integrate policy context, stakeholder perspectives, and insights from multiple disciplines to analyze causes and possible solutions to water level changes.
2) Inform decisions by building consensus on environmentally, socially, economically, and politically feasible policy options and management actions that various groups can take.
3) Use a place-based and regionally-minded approach, evaluating specific options for local areas while also identifying opportunities across the Great Lakes regions.
This document discusses addressing water level variability in the Great Lakes through adaptive management.

Field sampling will be conducted from the research vessel Nancy K with support from NOAA.
Cyanobacteria blooms may be better able to tolerate oxidative stress from hydrogen peroxide. Experiments showed that cyanobacteria were exposed to hydrogen peroxide levels typical of fresh and coastal waters without significant effects. Additionally, models demonstrate that hydrogen peroxide is produced photochemically in surface waters through interactions between ultraviolet light and chromophoric dissolved organic matter, with levels varying seasonally, suggesting cyanobacteria have adapted to deal with these environmental stressors.
This document discusses different approaches to decision support for sustainability: the information deficit model, heuristics and biases, passive "nudge" decision support, and active structured decision-making (SDM). It notes that providing more information may not be sufficient for improved decision-making. Both nudges and SDM are described as decision support approaches, with nudges leveraging heuristics for frequent, low-stakes decisions, while SDM breaks decisions into smaller steps to avoid heuristics and biases for infrequent, high-stakes decisions.
This document summarizes research on the impact of invasive quagga mussels on freshwater microbial communities. Specifically, it discusses 1) feeding experiments that showed quagga mussels significantly reduced bacteria populations compared to control samples, and 2) field observations noting lower bacterial abundances and changes in bacterial composition in lakes invaded by quagga mussels compared to non-invaded lakes. The research suggests invasive species can significantly impact native microbial communities through trophic interactions and biogeochemical cycling.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
