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.

Generate Ground Water Quality Map based in Jnanabharathi ward no.129, Bangalore, Karnataka state, India
This document outlines the process for reservoir characterization, which involves multi-disciplinary analyses including: 1) geological analyses of core data, well logs, and cross sections; 2) analysis of geological databases; 3) evaluation of source rock and rock mechanics; 4) geophysical evaluation and interpretation of seismic data; and 5) reservoir engineering analyses including completion and drilling evaluations. The results of these analyses will be integrated into reservoir models to identify potential drilling locations with greater producibility and returns on investment.
This document summarizes a study of the hydraulic performance of a zero-valent iron permeable reactive barrier (PRB) installed in 2002 at a former military base in Texas to treat groundwater contamination. Monitoring data showed increasing contaminant levels downstream, indicating the PRB was not functioning as intended. A detailed assessment was conducted in 2011-2012 involving analyzing existing data, surveying water levels, installing new monitoring wells, and using groundwater modeling. Results showed the PRB formed a partial barrier to groundwater flow that has intensified over 10 years, indicating a steady deterioration of hydraulic conductivity. Preferential flow paths through the PRB impact its effectiveness in controlling the plume's movement and contaminants' residence time for degradation. Model
Classification either on quality or type based for groundwater can offer great advantages especially in regional groundwater management. It provides a short, quick processing, interpretation for a lot of complete hydro-chemical data sets and concise presentation of the results. There is a demonstrable need for a quality assurance, with the advanced usage of world's largest fresh water storage i.e Ground water. Its getting depleted over the years and the quality of the same degrading with a rapid pace. Ground water Quality is assessed mainly by the chemical analysis of samples. The data obtained from the chemical analysis is key for the further classification, analysis, correlation etc. Graphical and Numerical interpretation of the data is the main source for Hydro-chemical studies. In this paper we test the performance of the many available graphical and statistical methodologies used to classify water samples including: Collins bar diagram, Stiff pattern diagram, Schoeller plot, Piper diagram, Durov's Double Triangular Diagram, Gibbs's Diagram, Stuyfzand Classification. This paper explains various models which classify, correlate etc., summarizing the water quality data. The basic graphs and diagrams in each category are explained by sample diagrams. In addition to the diagrams an overall characterization of hydro-chemical facies of the water can be carried out by using plots which represents a water type and hardness domain. The combination of graphical and statistical techniques provides a consistent and objective means to classify large numbers of samples while retaining the ease of classic graphical presentation.
The document summarizes a geotechnical analysis of material from Lake Badana in Italy that is being considered for reuse as inert material in concrete mixtures. Laboratory tests found the material contains no asbestos or harmful substances above legal limits. A stability analysis found the overall risk of landslides on the lakeshore is modest, with possible landslides only on the left flank. The analysis concludes the excavated material is suitable for reuse as inert in concrete after processing.
The document summarizes an assessment of a zero-valent iron permeable reactive barrier (PRB) installed in 2002 to treat trichloroethene (TCE) contamination at a former air force base in Texas. Monitoring showed the PRB effectively treated TCE for the first 5 years by promoting abiotic dechlorination. However, starting in 2008, concentrations of vinyl chloride and other daughter products increased downgradient. The assessment found the PRB performance was mixed - sections effectively treated TCE through abiotic and biotic processes, while other sections were bypassing treatment, causing increased downstream contamination. Geochemical data from different sections of the PRB supported varying levels of reactivity and treatment effectiveness over time.

This document summarizes a study on analyzing ammonia levels in groundwater samples from Chittagong, Bangladesh. Nine groundwater samples were collected from shallow and deep aquifers in different parts of the city. Laboratory analysis found high levels of ammonia associated with elevated arsenic and manganese, suggesting reducing conditions may control the release of arsenic and manganese in groundwater. Standard addition calibration produced a linear calibration curve with an R2 value of 0.9977. Ammonia results from the laboratory analysis mostly matched field measurements, though some samples may need to be reanalyzed. Further study of the hydrogeochemistry is planned to better understand factors controlling arsenic mobilization.

This document summarizes potential impacts of CO2 storage on groundwater resources. It discusses a study that modeled different scenarios, finding that pressure increases could extend beyond CO2 plumes but brine displacement would likely be over small distances and slow rates. While faults pose the highest risk, typical storage is unlikely to affect shallow groundwater. The document also reviews caprock properties important for storage integrity and outlines forthcoming IEAGHG studies on related topics.

This document summarizes the results of analyzing strontium isotope ratios (87Sr/86Sr) in pore water samples collected during Integrated Ocean Drilling Program Expedition 337 off Shimokita peninsula, Japan between 1289 to 2405 meters below seafloor. The ratios suggest mixing between ancient seawater and fluids derived from volcanic material alteration, as confirmed by smear slide observations showing weathered volcanic material. Ratios ranged from 0.7086 to 0.7061, with volcanic materials from the region having similar ratios to measurements at deeper levels, suggesting volcanic alteration is a source of fluids supporting deep microbial life in the area.
Integration of Seismic Inversion, Pore Pressure Prediction, and TOC Predictio...Andika Perbawa
Conventional natural gas is being exploited rapidly to achieve energy security and to satisfy the demand. However, due to the high demand for oil and gas it is becoming more difficult to find sufficient conventional reserves. To anticipate the predicted shortage of gas, we need to explore new, unconventional resources, such as shale gas. Shale gas is shale lithology that has high TOC, is brittle, and is located in the dry gas window zone. This study describes the early exploration of shale gas potential in one block in South Sumatra basin area.
In this study, the integration of geochemical data, rock physics and seismic inversion for characterizing and searching for shale gas potential will be described. The preliminary exploration stage of gas shale play covers sweet spot analysis using the Passey method to create a pseudo TOC in the target formation. Secondly, the overpressure area is mapped to avoid any potential pitfalls. Thirdly, seismic inversion is performed to map the distribution of shale based on the parameters Vp / Vs and map its TOC through conversion from Vp parameter.
As a result, log analysis shows one target zone of potential shale gas with TOC above 1% with a thickness of 100 feet. Integration of pore pressure data, shale distribution and TOC distribution of the target zone shows two potential areas in west, north-south trending, and in the east relatively of the well-X. Both locations can be recommended for the next pilot holes in order to acquire a complete set of new data and to be able to evaluate more intensively.

Sandia National Laboratories researchers presented a preliminary salt design concept for disposing of high-level radioactive waste and spent nuclear fuel in salt geologic settings. They proposed direct disposal of glassified high-level waste in stainless steel canisters and using robust steel overpacks for spent nuclear fuel. Waste packages would be emplaced transversely in just-in-time constructed drifts and immediately backfilled with crushed salt to limit radiation exposure and provide stability. Thermal analysis indicated waste package spacing of around 8 meters for spent fuel and 3 to 7.7 meters for high-level waste would be sufficient to limit temperatures. The design aims to simplify handling and take advantage of salt's ability to self-heal around the waste packages.
Many factors impacting the measurement precision of ICP-OES and ICP-MS are still often neglected for everyday operation, however. Sample preparation is one of the factors that play a crucial role in the success of high-quality sample analysis. In this webinar, our experts will discuss sample preparation to: 1) improve analysis precision 2) make difficult samples easy to be analyzed 3) eliminate sample dilution to minimize error introduction.

Geochemistry exploration involves measuring chemical properties in natural materials like rocks, soils, and water to identify abnormal patterns related to mineralization. It can be used at different scales from reconnaissance surveys over large areas with low sample density to detailed surveys over smaller areas with higher sample density. Different materials are suitable for different scales and types of surveys can help locate mineralized areas for further exploration.

Heavy metals like arsenic, lead, and mercury are naturally present in small amounts in the environment but can become toxic at higher concentrations. The document discusses the various forms and sources of these metals, how their mobility and toxicity depends on factors like pH, and their impacts on human and ecosystem health. It focuses on arsenic contamination of groundwater in Bangladesh and India, where over 60% of wells exceed safe drinking water standards. The source is natural arsenic released from sediments by microbial activity that breaks down iron oxides. Shallow wells below 60m depth have the highest arsenic levels, and geochemical tracing shows correlations between arsenic and methane or ammonia, suggesting microbial mediation of arsenic mobilization from sediments poses health

Mark Thomas_A digital soil mapping approach for regolith thickness in the com...TERN Australia
This document summarizes research on modeling regolith depth in the Mt Lofty Ranges of South Australia. Regolith includes all weathered material above bedrock and plays an important role in hydrology, biology, energy transfer, biogeochemistry, land use, and more. While some regolith maps exist, coverage is limited. The researchers collected over 700 depth measurements and used environmental data like topography, climate, and geology in a regression model to predict regolith depth across the 128,000 hectare study area. Their goal is to develop a consistent national regolith map to support biophysical modeling. Future work includes testing the approach in other regions and integrating results to create a comprehensive national map.
This document discusses a study on the environmental and health impacts of heavy metal contamination from the Zandfontein cemetery in Tshwane, South Africa. Samples were collected from soils and groundwater in and around the cemetery. Analysis found elevated levels of chromium, nickel, copper, zinc, arsenic, mercury, and lead in on-site soils compared to off-site soils. Groundwater samples also contained elevated levels of chromium, copper, zinc, mercury, and lead. Geophysical mapping showed groundwater flow paths transporting contaminants from the cemetery. Risk assessment found groundwater poses a health hazard and the cemetery has a high potential for polluting the underlying aquifer.

Biological Controls on Water Chemistry - November 21, 2012Richard S. Behr
This document summarizes how microbial activity controls water chemistry and influences earth systems. It provides examples of how microbes:
1) Mediate redox processes that control the solubility and speciation of many elements through respiration using various terminal electron acceptors after oxygen is depleted.
2) Degrade organic carbon, often introduced through human activities, which drives subsequent anaerobic respiration processes and changes in groundwater geochemistry.
3) Can unexpectedly increase the buffering capacity of systems, as seen through an experiment where microbial sulfate and nitrate reduction reduced the effectiveness of acidification in a lake.
The document outlines the study areas and methods for various ecological assessments including benthic communities, seabed habitats mapping, fish visual census, biodiversity, trophic interactions, mega fauna, coastal mangrove surveys, seawater quality sampling, sediment quality sampling, and plankton communities sampling. Fish visual census will be conducted along 100m transects involving underwater surveys and counts of fish abundance. Seawater and sediment samples will be collected from various depths and sites and analyzed for physical, chemical, and biological parameters to assess quality. Plankton samples will be collected using nets and analyzed in the laboratory.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
