This document discusses key issues related to water availability, quality, and costs for algae cultivation. It summarizes trends in groundwater salinity across the US and how the optimal salinity level for growing algae balances production versus water costs. Operating ponds at higher salinities in arid regions of the Southwest uses less water than in wetter Southeast regions. While elevated salinities reduce algae growth rates, they decrease water needs by reducing blowdown and disposal costs. Further research is still needed on regulating freshwater use, disposing of saline wastewater, and understanding impacts of water chemistry on algae productivity.

Enabling the Flow of Ecosystem Services from Agriculture to Improve Puerto Ri...National Institute of Food and Agriculture
This project aims to (1) reduce nutrient losses and nitrous oxide emissions from agriculture in Puerto Rico, (2) increase farmer flexibility and motivation to provide ecosystem services, and (3) develop additional farm revenue streams. The researchers will assess impacts of alternative management practices, quantify ecosystem service credits, identify areas for cost-effective emissions reductions, and estimate a regional supply curve for credits. Field trials will compare nitrous oxide and nitrate impacts of control and reduced nitrogen application rates on plantain crops.Historical Analysis of Agroenvironmental Conditions
This document summarizes a study analyzing historical agroenvironmental conditions in the Lower Mississippi River Basin. The study examined long-term trends in natural resources and the environmental impacts of agriculture using data on land use, precipitation, hydrology, and water quality. The researchers found evidence that intensive groundwater irrigation in agricultural watersheds has altered surface water flows, reducing base flows and increasing low flow events, compared to non-agricultural watersheds. While more analysis is needed, the results suggest tradeoffs between agricultural productivity and hydrologic alteration may need to be considered for sustainable management in the region.

We had a great turn out for the event and many positive comments afterwards. I think this was one of the biggest turnouts we've had for a Lynk and Learn.
Generation Lynk will look into ways to provide more information on the topics that interest our members.
MN Clean Water Land & Legacy
The document discusses efforts in Minnesota to monitor and improve water quality through the Clean Water Legacy Act. It provides background on the act and the process of identifying impaired waters, developing restoration strategies, and implementing projects. While millions have been spent, understanding impacts at different scales remains difficult. Key uncertainties include estimating natural recovery potential, constraining uncertainty, measuring effects of management actions, and determining the best ways to implement treatment trains. Long-term monitoring at sentinel sites is needed to better understand impacts and continue making progress on the goal of cleaner water.
Nutrient loss reduction potential
This document summarizes a study on drainage water recycling systems and their ability to reduce nutrient losses based on the size of on-farm water storage. The study uses data from 2006-2016 from the Davis Purdue Agriculture Center in Indiana to model various storage sizes from 2-10% of field area. Larger storage sizes were able to capture more annual drain flow and reduce nitrogen and phosphorus loads, with 8% storage capturing 66% of drain flow on average. The document concludes that drainage water recycling systems with storage sizes of 4-8% of field area can significantly reduce nutrient losses.
What are the Mos Pressing Water Issues Facing the U.S.?
This document summarizes the results of a Delphi survey conducted with federal government staff to identify the most important water issues for future funding by the USDA National Institute of Food and Agriculture (NIFA). The survey identified the top five issues as: 1) climate change and water quality/quantity, 2) water quality and conservation practices, 3) water quality and nutrients, 4) climate change adaptation/mitigation strategies, and 5) policy analysis of water quality/quantity. Additionally, the survey found that interdisciplinary research, stakeholder collaboration, and data sharing across agencies were highly important elements to incorporate into future project funding.
National Water Quality Initiative
The National Water Quality Initiative (NWQI) pilot project aims to:
1) Connect on-farm conservation efforts to watershed-scale assessments to improve water quality.
2) Demonstrate that targeted implementation of conservation practices can make meaningful progress on water quality goals.
3) Develop watershed-scale assessments during the pilot period to guide future investments in on-farm conservation efforts and increase water quality improvements.
Smart Phone Apps: Scientific Validation Quantification of Water Conservation
Smart Phone Apps: Scientific Validation Quantification of Water ConservationNational Institute of Food and Agriculture
This document summarizes a project that developed smartphone apps to help farmers and homeowners conserve water through more efficient irrigation scheduling. The apps were validated through field trials in Florida and Georgia on turfgrass, cotton, citrus and peanuts. The trials found the apps reduced irrigation by 24-90% compared to traditional scheduling, while maintaining or increasing yields. Future work will expand the apps to more areas by incorporating national weather data and account for factors like citrus disease. The goal is to help address water shortages projected for the Southeast U.S. through improved irrigation water management.Recommended

Innovative Policies to Optimize the Allocation of Water Quality and Conservat...National Institute of Food and Agriculture
This document summarizes the progress and preliminary results of a research project studying water quality and flows in the Lower Suwannee/Santa Fe River Basin in Florida. The research is using a hydrological model to evaluate conservation measures, surveying agricultural landowners about adoption of practices, surveying recreational users of springs to value water quality improvements, and developing educational outreach programs. Preliminary analysis of the recreational user survey found most participated in swimming and other activities, spent on average $99 on visits, and higher entrance fees would significantly decrease visit frequency.Why Xeriscaping Makes Good Sense - University of Georgia
Metro Atlanta is reaching the limits of its water resources due to population growth and increased landscaping. Xeriscaping, which uses principles like limited turf areas and water-efficient plants, can reduce outdoor water usage without sacrificing aesthetics. Xeriscaping benefits water authorities by extending limited water supplies, homeowners through reduced maintenance costs, and greenhouses that profit from increased plant and mulch sales. Xeriscaping makes good sense for conserving water resources.

Sharpley - The Importance of Monitoring to Determine Farm ImpactsSoil and Water Conservation Society
The document discusses water quality monitoring of the C&H Hog Farm located near the Buffalo National River in Arkansas. Key findings from monitoring the farm's impact on nutrient, sediment, and bacteria levels in nearby Big Creek and springs include: 1) Nitrate-N and phosphorus levels were similar or slightly lower downstream than upstream; 2) E. coli levels were highly variable between sites and storms; and 3) No consistent trends have emerged so far to indicate water quality issues. The document emphasizes that monitoring must continue to provide transparency and data for permitting agencies, while acknowledging extreme views on either side may not be swayed.LEED Credit 6.2-Final Poster
The document discusses several case studies of campus-wide stormwater management systems that implemented best management practices (BMPs) like rain gardens, vegetated swales, and wetlands to capture and treat stormwater runoff. At Miami University, these BMPs could help capture 90% of annual rainfall and remove 80% of suspended solids if designed according to state standards. At Wheaton College, a wetland and vegetated swale reduced total suspended solids by 80%. Miami University would need strategies like porous pavement, rain gardens, and cisterns to capture over 8 million cubic feet of runoff from its 229 acres of impervious surfaces.

Ben Starr_AHA Paper_Final
This document discusses a proposed method for dynamically varying water flows to balance the needs of landholders and aquatic ecosystems. Sensors and cloud computing could be used to better meet the flow needs of ecosystems identified by recent research, like certain flows acting as cues for breeding. A case study shows DNRM currently uses cloud software to automate notifications to landholders based on flow data. The proposal aims to maximize benefits for both stakeholders by restricting extraction only when flows provide little ecosystem benefit, while ensuring total annual water availability for irrigation is not reduced.

Final_Water_Document
This document analyzes water usage in multi-unit complexes (MUCs) in Saskatoon. It finds that high-rise MUCs have seen decreasing water usage while low-rise usage first increased and then decreased. MUCs with fewer units tend to use more water per unit. Areas with many MUCs do not necessarily have high per-unit usage. Retrofitting MUCs to reduce usage can be cost-effective. Surveys found MUCs do not prioritize conservation but open to initiatives. Partnering with other groups on rebates could incentivize retrofitting and reduce water usage.

State report on Gatineau Park ecosystemsNational Capital Commission - Commission de la capitale nationale
The overall condition of Gatineau Park is “good”, confirms the National Capital Commission’s (NCC) Status Report on Gatineau Park Ecosystems. In 2006, it was deemed “acceptable.”
The Status Report on Gatineau Park Ecosystems seeks to evaluate the health of Gatineau Park’s ecosystems by measuring up to 10 years of data against ecological health indicators. This status report looks at the long-term trends in Gatineau Park, and identifies several issues of concern. The status report will also inform the renewal of the Gatineau Park Master Plan, which will be completed by 2021.
Since the launch of the Gatineau Park Conservation Plan (2010), the NCC has made progress on addressing issues of concern, and will continue to work with its partners, stakeholders and municipalities to improve the ecological health of the Park.Metz Lateral Conservation Project
This document summarizes a collaboration between 15 local, state, federal, non-profit, corporate, agriculture, and private partners to reconstruct a stream through the Metz Lateral Conservation Project. The partners worked together to benefit both agricultural production and conservation by implementing a two-stage ditch design that provides stable banks, minimal maintenance, increased capacity, and nutrient reduction while balancing increased initial costs and loss of tillable land. Communication between all involved parties was key to the ultimate success of the large-scale project.

http://waterandfood.org/ganges-conference/32. soil alkalinity and salinity by Allah Dad Khan
Saline soils occur where precipitation is less than evapotranspiration, causing cations like sodium, calcium, and magnesium to accumulate. This raises soil pH above 8.5. Salinity hinders plant growth by limiting their ability to take up water. Specific ions like sodium also interfere with potassium uptake.
Phosphorus and nitrogen are often deficient in alkaline soils. Phosphorus reacts with calcium, aluminum, and iron to form insoluble compounds unavailable to plants. Nitrogen is lost through volatilization or leaching. Micronutrients like iron and zinc also have low solubility in alkaline conditions. Maintaining soil organic matter helps buffer these issues.

It discusses how increasing salinity is affecting over 35 million people in coastal districts through issues like lack of drinking water and reduced agriculture. Salinity has increased the amount of affected land area over time. It outlines objectives to understand the effects and management of coastal saline soils and impact on crop production. It then reviews literature on characteristics of coastal soils and salinity levels. Findings show over 50% of coastal areas are affected by salinity, reducing crop yields. Causes of salinity intrusion include geographical location, sea level rise, and shrimp cultivation. Recommendations include developing regional policies and strategies and building capacity for integrated water resources management.
Soil Salinity in India
This document discusses soil salinity in India. It begins by defining soil and its components. It then explains that saline soils are commonly found in arid and semi-arid regions with low precipitation. In India, about 7 million hectares of land have reduced crop yields due to soil salinity. The document categorizes the different types of saline soils found in India based on their characteristics such as saline soil, saline-alkali soil, and saline-sodic soil. It concludes by noting that excess soil salinity can greatly impact plant growth and crop production.
Salinity
Salinity is a measure of the total amount of dissolved salts in water, measured in grams per kilogram or parts per thousand. Seawater contains 11 major dissolved constituents that make up over 99.99% of all dissolved materials, with the largest proportions being chloride at 55.07% and sodium at 30.62%. Salinity affects the distribution of ocean plants and animals as well as other seawater properties like density and dissolved oxygen levels.
7-Waterlogging and salinity
This document discusses waterlogging and salinity issues in soils. It defines waterlogging as soils saturated with water and describes various causes of waterlogging including seepage from canals, poor drainage, and excessive irrigation. It outlines effects on plant growth like reduced oxygen and gas exchange. Reclamation methods include interceptor drains and pumping groundwater. Salinity is defined as salt presence in soils. Causes in Pakistan include poor leaching and irrigation/groundwater. Classification depends on salt levels and composition. Effects on plants include reduced water availability and specific ion toxicity. Reclamation involves leaching, crop selection, and adding organic matter or chemicals.

Water logging salinity
Water logging occurs when excess water at underground levels rises to the surface due to natural flooding, over-irrigation, or inadequate drainage. This displaces air in the soil and changes soil processes, accumulating toxic substances that inhibit plant growth. Water logging can be caused by permanent or periodic submersion of land, heavy rainfall, or artificial irrigation in low-lying areas. It leads to inhibited soil bacteria activity, reduced available water and temperature, and impaired air circulation and increased salt levels in the soil. This delays cultivation, promotes unwanted plant growth, and negatively impacts health. Solutions include improving drainage, reducing water percolation from canals, restricting excess irrigation, and removing obstructions to natural drainage.
water logging and salinity in pakistan by Musadiq Rehmani
The document discusses water logging and salinity issues affecting agriculture in Pakistan. It states that 50% of irrigated lands in Pakistan are affected by water logging and salinity, reducing crop yields and farmer incomes. Drainage systems are needed to control water logging by allowing excess irrigation water to drain away and leach out salts. Biological controls and choosing tolerant crop species can also help reduce the impact of water logging on agricultural production.
Salinity stress tolerance in plants master seminar
1. Plants have developed three main adaptations to salinity stress: osmotic stress tolerance, sodium exclusion from leaves, and tissue tolerance to accumulated sodium and chloride in leaves.
2. Mechanisms of salinity tolerance include compartmentalization of ions, osmotic adjustment through compatible solutes, and exclusion of sodium from leaves.
3. Breeding efforts have developed salt tolerant varieties of crops like rice, wheat, mustard, and chickpeas through marker-assisted selection and identifying favorable quantitative trait loci.
Drip irrigation
The document provides an overview of different types of micro irrigation systems and their benefits over traditional irrigation methods. It discusses various irrigation techniques such as surface irrigation methods like flood, furrow and basin irrigation, and pressurized methods like sprinkler and drip irrigation. It explains the key factors to consider when selecting an irrigation method, and highlights the advantages of micro irrigation systems such as efficient water use, higher crop yields, and reduced insect and disease problems.
Ppt on irrigation
This document summarizes four main irrigation methods: surface irrigation (flooding), sprinkler irrigation (applying water under pressure), drip or trickle irrigation (applying water slowly to the soil), and sub-surface irrigation (flooding water underground). Surface irrigation is the most widely used method, covering 90% of irrigated land. Sprinkler irrigation is ideal for scarce water areas. Drip irrigation conserves water, controls weeds, and applies water at a slow rate matching crop needs. Sub-surface irrigation is used where soil and topography allow watering underground.
Water / Wastewater - groundwater levels, dry land salinity and drought in Ade...
Adelaide’s main source of water comes from the River Murray and the Mount Lofty catchment area and connects to the reticulation system. Urban stormwater is a major input to surface water with a number of natural creeks discharging to stormwater drains. Although the major source of water comes from the surface water, ground water is also vital resource. Rising groundwater levels, dry land salinity and droughts are major problems in Adelaide. This presentation offers solution to these problems.

Suitability Assessment of Shallow Groundwater of a Typical Coastal Aquifers f...
Shallow Groundwater of a coastal aquifer has been intensively used as a source of water for
irrigation farming in the Niger Delta region of Nigeria. To assess the usability of this water for irrigation use,
twenty locations at buguma city were mapped out and five water wells were sampled for each location using
Simple random sampling technique. Each sample was analyzed for the cations(magnesium(Mg2+), sodium(Na+
),
potassium(K+
),calcium(Ca2+)),anion(nitrate ion(N03
-
)), trace elements(cadmium(Cd), iron(Fe), and zinc(Zn)and
other phsico-chemical parameters(Salinity(SI), electric conductivity(EC) and pH) adopting standard methods.
Based on the analyzed parameters, irrigation water quality parameters (RSC, SAR, %Na and %MR) and
indexes(Kelly index(KI), Permeability Index(PI) and the Canadian water quality index(CWQI)) were calculated
.To assess the usability of the shallow groundwater, results of the Water quality index models and other
calculated irrigation parameters were compared with the standards. On the average, virtually all the sampling
locations except Ombu, Igba and Jackreech were unsuitable for irrigation use.
H012615560
This document summarizes a study assessing the suitability of shallow groundwater from coastal aquifers in Buguma City, Nigeria for irrigation purposes. Water samples from 100 wells across 20 locations were analyzed for various physicochemical parameters including heavy metals, salinity, pH, sodium adsorption ratio, and more. The results showed elevated levels of iron and sodium adsorption ratio that exceed standards for irrigation water in many locations. This indicates the water is generally unsuitable for irrigation due to risks of clogging irrigation systems, displacing calcium in soil, and causing soil and plant health issues like stunted growth. Only 3 of the 20 locations were found to have water suitable for irrigation based on the water quality index and parameter assessment.

This document presents research on approaches to mitigate pollution from the herbicide MCPA (2-methyl-4-chloro-phenoxyacetic acid) in water catchments used as drinking water sources. The research monitored MCPA concentrations spatially and temporally in an agricultural catchment in Ireland that supplies drinking water. Key findings include: MCPA concentrations exceeded drinking water limits and persisted in the system; concentrations increased downstream; and concentrations correlated positively with improved grassland and negatively with rough grazing land use. The research demonstrates the need for enhanced monitoring and questions the sustainability of certain land uses like improved grassland near drinking water sources.
Macedo et al (2015)-Irrigation Groundwater Quality for Agricultural Use
The document summarizes a study on assessing irrigation groundwater quality for agricultural use in Ekxang Village, Lao PDR. Daily field tests were conducted to measure parameters like EC, TDS, pH, and temperature of the groundwater. Laboratory analyses found that mean EC and SAR were below thresholds for crop tolerance, indicating groundwater quality was suitable for agriculture with low salinity and sodicity risks. While groundwater irrigation could help smallholders adapt to climate change, constant monitoring of quality is needed to sustainably increase crop yields and soil health.
Measured effects of conservation watershed scale
This document summarizes findings from multiple watershed-scale studies on the effects of conservation practices conducted between 2004-2018 as part of the USDA CEAP program. Key findings include:
1) The implementation of conservation practices like cover crops, riparian buffers, and nutrient management plans effectively reduced nutrients and sediments in surface waters in several watersheds across the country.
2) Models were used to identify priority areas for conservation and predict load reductions, however watershed responses were complex and variations in practices and conditions made broad effects difficult to detect.
3) While edge-of-field water quality often improved with conservation practices, stream impacts were more dependent on factors like bank erosion and riparian conditions.

A Framework for Setting Realistic Expectations for Water Quality Improvements...Soil and Water Conservation Society
This document presents a framework for setting realistic expectations for water quality improvements based on changes in agricultural activities. The framework considers how chemicals and sediment from fields enter the stream network through different flowpaths like surface runoff, subsurface drainage, and groundwater. It also accounts for how the chemical behavior of different substances influences their transport. The framework can be used to evaluate how specific agricultural management practices might affect water quality in different hydrologic settings by trapping, reducing, or removing chemicals and sediment. Examples are given to illustrate how the framework can set expectations for practices like buffer strips and no-till tillage.Food-Water-Energy Nexus in Central Asia

Emma description
Akvaplan-niva conducted a 2-year study in the Philippines to monitor the environmental impacts of aquaculture and develop predictive models. They trained government staff in monitoring equipment use, data analysis, and using models to assess impacts and estimate safe production levels. Baseline surveys were performed in 3 areas, collecting data on bathymetry, water quality, weather, and production levels. Models were developed to predict impacts and estimate carrying capacities based on water exchange, nutrient sources, and phytoplankton growth. The models suggested one area exceeded capacity while another may not, and management measures were recommended to reduce impacts and increase capacities.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

ABO salinity presentation pnnl
- 1. Water Cost and Availability for Algae Cultivation- Salinity Issues ERIK R. VENTERIS AND MARK S. WIGMOSTA June 10, 2013 1 Spatial Modeling Research Engineer Richland, WA PNNL-SA-95574
- 2. June 10, 2013 2 Overview Key issues- water availability, quality, and associated costs Relevant PNNL Biomass Assessment Tool (BAT) capabilities (open ponds)- Algae productivity from climate and salinity data (M. Huesemann, PNNL) Evaporative water demand (met data, pond state simulation) Water source characterization, availability and costs Competitive freshwater salinity <2,000 mg L-1, relatively shallow <1,000 ft, municipal and/ or agricultural use Non-competitive saline water salinity generally too high for crops (>2,000 mg L-1), depth <3,280 ft Seawater- unlimited supply, salinity ~35,000 mg L-1, consistent ion chemistry This presentation- National trends in freshwater availability and groundwater salinity What is the best operating salinity to balance production value and water costs? For organism X and salinity of water source, what are supply and saline disposal costs (CAPEX and OPEX)? Note that we do not follow NRC model of freshwater + brackish mix
- 3. Competitive water (Fresh) Availability Details in Venteris et al., 2013, Environmental Science and Technology Strong E/W gradients, especially for southern half of the US 3
- 4. Salinity trends in competitive (fresh) waters Geostatistical simulation based on nearly 200,000 data points Patterns related to interaction between geology and climate Even waters defined as “fresh” have significant salt content 4
- 5. Salinity trends in non- competitive (brackish/ saline) groundwater Less data (21,000 data points), more clustering, more uncertainty Higher salinity waters related to sedimentary basins, oil-gas occurrence 5
- 6. June 10, 2013 6 Tradeoff Modeling- Operating Salinity What is best compromise between growth rate and water costs? As pond operating salinity goes up, in general- Algae growth rate and biofuel production decreases (Chlorella, N. salina) Total makeup water and associated costs decrease (blowdown) Smaller pipelines Fewer supply wells Less saline concentrate for disposal (by geologic injection or evaporation ponds) Costs based on pipelines (seawater) or wells and pipelines (ground waters) GIS models connect each farm site to optimal water source Calculate (biofuel production value – water costs) for range of salinities
- 7. Operating Salinity- N. salina and seawater June 10, 2013 7 4,654 485 Ha Unit Farm Sites
- 8. 16,024 485 Ha Unit Farms 38,678 485 Ha Unit Farms Operating Salinity- Chlorella and competitive waters June 10, 2013 8 Southwestern US Southeastern US 5-7 g kg-1 2-3 g kg-1
- 9. Operating Salinity- Chlorella and saline waters June 10, 2013 9 Southwestern US Southeastern US ~15 g kg-1 7-10 g kg-1 Use Chlorella or more salt-resistant species?
- 10. June 10, 2013 10 Conclusions, future directions Regional trends in salinity impact water availability and costs Understanding interactions between organism growth and water source geochemistry is critical. Elevated water source salinity and evaporation rates in SW require that ponds be operated at a higher salinities than in the SE. Many water issues remain to be addressed, including- Regulatory constraints on freshwater supplies and saline concentrate disposal Temporal trends in competitive uses (development, climate change, etc.) Brackish and saline groundwater sustainability (volumes, recharge etc.) Growth performance vs. pH, ion chemistry, etc. (for example, NaCl water vs. bicarbonate waters…)
Editor's Notes
- Brief overview of PNNL’s efforts in water resource modeling.Discuss national patterns in groundwater salinityHow do these impact overall water costs? (Supply and concentrate disposal)
- Freshwater availability model based on average discharge measured at stream gauges.Supply limited to 5% total dischargeEach dot is 485 ha unit farm, black supplied, gray unsupplied. Priority on water supply costsEW gradients
- Low salinity waters in east and south east, some areas of upper Midwest, Pacific NorthwestSalinity of competitive waters much higher in the south west, Rockies, Great Plains.Saline concentrate disposal essentially unavoidable.
- Non compete less information, generally deeper, higher salinity, etc.
- As an approximation, utilization of non-compete waters requires roughly 2x increase in operating salinity.
