Contaminated mine drainage on abandoned coal mine sites can be treated by passive or active treatment techniques. Passive treatment is less costly than active treatment, but its reliability is often questioned. This paper presents a simple design approach that has been used to design passive treatment systems in Pennsylvania for the past 20 years. Four systems that demonstrate commonly utilized passive technologies are described and long-term data are presented. The systems have provided highly reliable and effective treatment for 3-18 years. The data demonstrate that properly designed, constructed, and maintained passive treatment systems are a highly cost-effective solution for contaminated mine discharges on AML sites.

Effective passive minewater treatment systems can be attractive to the public because they do not contain hazardous components, support wildlife, and communicate a resonating message of frugal ingenuity. This talk will focus on two passive treatment systems in Allegheny County that have become central components of popular public spaces: Allegheny Land Trust’s Wingfield Pines system and Pittsburgh Botanic Garden’s Woodlands system. The presentation will be supported with photos and statistics regarding the public use of both systems.
Because of the extent of AMD impacts in Pennsylvania, the Commonwealth has become, by necessity, a leader in the development of passive treatment technology. People from around the world travel to Pennsylvania to learn about the successes we have collectively achieved, including the installation of over 300 passive treatment systems. In recent years, the capabilities of passive systems to treat highly acidic mine discharges with high concentrations of dissolved metals has been questioned. It is important to remember that with any treatment system, whether passive or active, proper design, suitable land characteristics, quality construction, proper maintenance and sufficient funding, are needed to provide a long-term, cost-effective approach for watershed restoration. This presentation will provide mini case studies that demonstrate, by example, that passive systems can and are effectively treating acidic, high-metal, discharges in Pennsylvania.

Preliminary Technical Evaluation of Three Reports by U.S. Environmental Prote...LPE Learning Center
http://www.extension.org/72802 The Yakima Valley is a large agricultural area where there are multiple potential sources of nitrate in groundwater. Potential sources are intermingled, i.e., homes with septic systems are on the same properties as the dairies or adjacent to farms and/or dairies. In 2012, Region 10 of the US Environmental Protection Agency undertook a study to source track and identify nitrogen sources in the Yakima River Basin as part of an enforcement effort focusing on dairies. EPA position was that the targeted dairies did not properly apply nutrients to land application fields at agronomic rates, resulting in groundwater contamination. The study area is underlain by 3 aquifers, a shallow perched aquifer likely related to irrigation return flows, an alluvial aquifer and an underlying basalt aquifer. The three aquifers are hydrologically connected either through natural pathways or through wells completed into more than one aquifer. Because none of the potential sources are isolated, source tracking requires an in-depth knowledge of aquifer properties such as aquifer thickness, groundwater flow direction, hydraulic conductivity, and vertical leakance in addition to understanding localized effects of ditches, drains and production wells on groundwater flow. EPA focused on groundwater chemistry, assuming that indicators such as pesticides and other trace organic compounds would tie the groundwater nitrate to a specific source. EPA’s study failed to yield clear indicators pointing to specific sources and did not collect hydrologic data for its 2012 report to gain a detailed understanding of aquifer properties. This presentation will address how to accurately characterize the hydrogeology below dairy production areas and land application fields, and how to proactively manage nutrients to protect dairies from unsubstantiated enforcement actions.

Manganese limits set forth by the Clean Water Act were not based on the toxicity of Manganese. And, as it turns out, the side effects from the treatment for manganese removal is a problem, not the Manganese. West Virginia adopted what is known as the “Five Mile Rule”, which stated that the human health criterion for manganese would only apply within a five mile zone up-stream from a public intake. This action, along with the existing available tools such as Alkaline Mine Drainage limits (No manganese) and Post Mining Limits (Report Only Limits) helped to substantially reduce the adverse effects created from the treatment itself.

Seismic attributes are being used more and more often in the reservoir characterization and interpretation processes. The new software and computer’s development allows today to generate a large number of surface and volume attributes. They proved to be very useful for the facies and reservoir properties distribution in the geological models, helping to improve their quality in the areas between the wells and areas without wells. The seismic attributes can help to better understand the stratigraphic and structural features, the sedimentation processes, lithology variations, etc. By improving the static geological models, the dynamic models are also improved, helping to better understand the reservoirs’ behavior during exploitation. As a result, the estimation of the recoverable hydrocarbon volumes becomes more reliable and the development strategies will become more successful.
Increasing interest by governments worldwide on reducing CO2 released into the atmosphere form a nexus of of opportunity with enhanced oil recovery which could benefit mature oil fields in nearly every country. Overall approximately two-thirds of original oil in place (OOIP) in mature conventional oil fields remains after primary or primary/secondary recovery efforts have taken place. CO2 enhanced oil recovery (CO2 EOR) has an excellent record of revitalizing these mature plays and can dramatically increase ultimate recovery. Since the first CO2 EOR project was initiated in 1972, more than 154 additional projects have been put into operation around the world and about two-thirds are located in the Permian basin and Gulf coast regions of the United States. While these regions have favorable geologic and reservoir conditions for CO2 EOR, they are also located near large natural sources of CO2.
In recent years an increasing number of projects have been developed in areas without natural supplies, and have instead utilized captured CO2 from a variety of anthropogenic sources including gas processing plants, ethanol plants, cement plants, and fertilizer plants. Today approximately 36% of active CO2 EOR projects utilize gas that would otherwise be vented to the atmosphere. Interest world-wide has increased, including projects in Canada, Brazil, Norway, Turkey, Trinidad, and more recently, and perhaps most significantly, in Saudi Arabia and Qatar. About 80% of all energy used in the world comes from fossil fuels, and many industrial and manufacturing processes generate CO2 that can be captured and used for EOR. In this 30 minute presentation a brief history of CO2 EOR is provided, implications for utilizing captured carbon are discussed, and a demonstration project is introduced with an overview of characterization, modeling, simulation, and monitoring actvities taking place during injection of more than a million metric tons (~19 Bcf) of anthropogenic CO2 into a mature waterflood.
Longer versions of the presentation can be requested and can cover details of geologic and seimic characterization, simulation studies, time-lapse monitoring, tracer studies, or other CO2 monitoring technologies.

The slickwater stimulation of unconventional gas and oil shale plays creates flowback water with a composition that is unique to particular shale formations. Characteristically, these fluids contain high concentrations of salts (e.g., chloride, bromide) which are routinely determined using ion chromatography. This analysis typically requires sample preparation, including manual dilution, which can significantly increase the cost of analysis. Results presented will show highly reproducible determination of anions and cations from Marcellus Shale flowback water using inline conductivity to identify high salt samples and then automatically diluting them prior to injection, saving time and column life.
Analysis of Anions and Cations in Produced Water from Hydraulic Fracturing Using Ion Chromatography
This presentation describes the use of ion chromatography (IC) to determine anions and cations in produced water from three different hydraulic fracturing sites. Considerable variation in ion concentration was found, which was attributed to differences in the geology of the locations from which samples were obtained.
A Review of Zeolite Based Treatment Water Systems and Thier Applicability in ...Daniel Eyde
The revisions to the Clean Water Act, ever lower NPDES water discharge standards and competition for scarce water resources have increased the need for cost-effective water treatment products and applications. Many water treatment sites are remote and lack infrastructure, others are passive or semi-passisve wetlands and bioreactors whose effluent, while meeting discharge standards, still require additional treatment for turbidity, COD, BOD and pH adjustment. The use of natural zeolites, alone or in conjunction with other treatment technologies, have had success in mitigating amD/amR discharges, as well as heavy metals, turbidity, NH4+, Al, Mn and silica in coal and hard rock mining impacted effluents. In uranium mining areas and NURE impacted waters, treatment systems initially designed more for problems like for Three Mile Island and Fukushima have been effective in capturing radionuclides in both passive and active treatment systems, most recently at the Homestake Uranium Tailings at Grants, NM. The applicability of the ion exchange and filtration capabilities of zeolites, their ability to be used in passive treatment systems and their limitations are reviewed.
Reverse Osmosis module design and engineering emerged with membrane technology
evolution. In order to understand module design, first membrane configuration needs to be
explored, since the module design is always tailored according to the membrane
characteristics. There is a significant difference between membrane chemistries (most
important ones being cellulose acetate and thin film composite with polyamide barrier
layer), and more importantly, between the different membrane configurations (hollow fine
fiber and flat sheet). Therefore, before looking into detail on the module configuration, the
membrane development needs to be considered.

Metal Reclamations Units (MRUs) are passive, modular, scalable, rapidly deployed wetland bioreactors. The biofilm which grows upon the support matrix inside the MRUs is self-selecting and determined by the introduced pollutants and how they are attenuated throughout the treatment process. Currently, our systems function as tertiary treatment at six sites removing Mn and Al, pH<7,><5.5> minimum, demonstrated rates up to 4kg/day of Fe captured using two MRUs Mk1.5s in series, residence 20-25 minutes, flow 280Lpm (5).

The Lausanne Tunnel in Jim Thorpe was installed in 1906 to dewater the coal fields in this area. The tunnel discharges about 6000 gal/min of drainage that is relatively high in iron and manganese but fortunately, the pH is relatively high and aluminum content is low. The remediation installed in 2004 was a two part passive wetland system that has been the focus of the conservation efforts by a number of conservation organizations since that time. My involvement has been to engage the local Sierra Club as well, the local trout stocking clubs and other organizations to provide funding and manpower for upgrades at the site. In 2007, two 5ft rectangular weir flow monitors were installed, one in the wetland and the other in the bypass flow, which consists of 2/3rd of the tunnel discharge flow. Pressure transducers and solar powered data loggers were installed to record both flows so that further hydrological engineering could be applied to optimize the wetland treatment while also devising a treatment plan for the bypass flow. In 2011, artesian aerators were added to the feeder pipes to improve aeration of the water entering the wetland. The aerators, however, did consume some of the available head pressure and reduced wetland feed flow so in 2014 a 3rd 14” feeder pipe was excavated and installed bringing the wetland flow rate back to the 1800 gal/min design rate. In 2016, a solar powered compressor was installed with two aerator heads added to the wetland to further boost dissolved oxygen. Iron test kits and dissolved oxygen monitors have been used to evaluate the iron removal effectiveness of the wetland and the extent of oxygen saturation. The next steps at for further improvement are the installation of cascading settling basins in the bypass flow as well as optimization of the wetland flow distribution. This presentation will feature presentation of technical flow and composition data as well as drone video of the site.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

The system was designed to be flushed and recover the
very high Al, but essentially no flushing was done by Southern
Alleghenies Conservancy.
The VFP is largely plugged with Al

2A performs well but 2B not
treating due to broken valve.
Combined system sampled in
DEP survey.
2A system treats well since conversion to BCR, but 2B and combined
outflow is acid due to valve problem and possibly 2B problems.

DEP sample from wetland
outflow was acid –
Leakage from Inflow sys.
System appears to be releasing net alkaline water, but leakage
from inflow boreholes is untreated so final outflow is acid.
Maintenance underway.

Part of the 10/15 discharge did not go into the VFP’s and was not
treated, giving net acid outflow at A, but total set of systems gave
net alkaline at B.

18. Many of the “failures” in the DEP Survey are
actually treating well when sampling and
effects on streams are considered.
Some systems suffer from poor
design/construction or lack of maintenance.
Large flows of very bad AMD can be treated
successfully with proper designs and
maintenance.
Cost of passive treatment is considerably
lower than active for most sites
19. PA should continue to fund well designed
passive systems, and improve expertise in
evaluating proposals to weed out poor
designs.
DEP should fund Watershed Managers to
monitor and back up maintenance.
Funds for TAG grants and other maintenance
should be continued or increased.
The large negative demerits for “High Risk”
systems in the DEP AML evaluation should be
removed or modified.
