Groundwater Quality. Information on the intrinsic vulnerability and risk from development are insufficient; however, no oil and gas xxxxx exist within this area. Therefore, the Parties agree to classify a groundwater unit as a class 1. Groundwater Quantity: Available information such as well density and knowledge of water use indicate a low demand; therefore, the Parties agree to classify the groundwater unit as a class 1. The BMC will work to develop a reproducible approach for classification of Transboundary Groundwater that meets both Parties’ interests. The BMC will begin this work by reviewing relevant risk assessment tools (e.g., The British Columbia, Yukon and Northwest Territories Trans- boundary Groundwater Area Classification Scheme, a modified version of the BC Aquifer Classification System, produced by British Columbia). The method will improve over time as more data are collected. Factors to be considered in the development of a reproducible approach to classification of Transboundary Groundwater include, but are not limited to, Groundwater quality, Groundwater quantity, domestic well density, community xxxxx, irrigation and other large production xxxxx, water source xxxxx, surficial geology, hydrogeologic and subsurface geology data, land use (including assessment of risk from hydraulic fracturing and deep water injection, etc.).
Groundwater Quality. The purpose of this Annex is to gain a better understanding of how groundwater influences Great Lakes water quality and ecosystem health, and to identify priority areas for future action. Groundwater may represent as much as 50% of the water entering the Great Lakes, either directly (via groundwater discharge along the coasts) or indirectly (via discharge into rivers and streams that then discharge into the lakes). Groundwater‐based contaminants and excessive nutrients can impair the quality of the waters of the Great Lakes, particularly the nearshore region, with potential effects on aquatic species and recreational waters. Because groundwater is a potential source of contaminants and excessive nutrients and a pathway for transfer to the Great Lakes, groundwater quality is linked to the successful delivery of key commitments in other Annexes, including Areas of Concern, Lakewide Management, Harmful Pollutants, Nutrients, and Habitat and Species. Some areas near the Great Lakes are known to have contaminated groundwater. In some cases, initiatives are underway to direct management and/or implement remediation actions in these locations. They include provincial contaminated site remediation efforts such as the Deloro Mine Site, and some of the work done through the Federal Contaminated Sites Action Plan, and the federal remediation of the Port Hope Area. These actions will protect or improve the water quality of the Great Lakes. This Annex includes commitments to develop a binational state of Groundwater Science Report, create an interagency groundwater issues team, identify priorities for future research, and identify priority areas and sites for monitoring, management or remediation actions to address groundwater impacts and stressors.
Groundwater Quality. 3.1.4 Surface Water Quality
Groundwater Quality. Overburden Groundwater In general, the measured concentrations of dissolved phase BTEX compounds, PAHs, and cyanide in overburden groundwater are relatively low or non-detect (see Figure 39 in Appendix A). However, groundwater samples from overburden monitoring xxxxx in which NAPL was observed (Figure 33 in Appendix A) were not analyzed per approved procedures.
Groundwater Quality. In the event that significant adverse changes to water quality parameters are noted in one or more of the monitoring xxxxx, Xxxxxxxx shall isolate and identify the source of the problem. If the pollutant source is identified as the Landfill, Xxxxxxxx will use one or more of the following options to prevent further pollution or such other method as may be agreed upon by the parties:
Groundwater Quality. The groundwater in the San Xxxxxxxx Basin is known to the Parties to contain elevated levels of volatile organic compounds, nitrates, and other contaminants. Los Angeles shall not be held responsible for the quality of the groundwater that is exchanged under the terms of this Agreement. Burbank shall take full responsibility for any necessary groundwater treatment that may be required to make groundwater exchange under this Agreement suitable for delivery to Burbank. Nothing in this Agreement however affects the rights and powers of any regulatory or governmental body that has oversight over the condition of groundwater, such as the United States Environmental Protection Agency, to determine and assess the liability of any party to this Agreement relating to the condition of any such exchanged groundwater.
Groundwater Quality. In several participant countries, like in Denmark, Holland, Lithuania, the Czech Republic, the Slovak Republic, Italy and France the character of the management of hydrochemical data is common with the groundwater heads data described above in detail and the related data supplying organisations are also the same. In the following only deviating characteristics will be addressed concerning this subject (Annex 1. Fig.5. and Annex 2 Tab.5). In Austria, like groundwater heads data, hydrochemical records are collected only on national level but they are gathered by another organisation, namely by the Umweltbundesamt being also responsible for data management and publicity. In Spain regional data collecting organisations (River Basin Authorities) provide free access to hydrochemical monitoring data on the Internet. In contrast to groundwater heads data national hydrochemical recordings are free in Sweden and they can be accessed via web. In Hungary the Environmental Nature and Water Inspectorate collects hydrochemical monitoring data. The related national database is under construction; therefore the available data are currently stored in Excel format that can be accessed for internal use only. In Slovenia hydrochemical monitoring data can be accessed only in the form of summarising reports in the web-page xxxx://xxx.xxxx.xxx.xx/podro~cja/vode/poro~cila_in_publikacije/podzemne_letna.html. 9 Hydrogeological maps Hydrogeological maps are assigned to three thematic groups as follows: maps of groundwater heads, maps of groundwater quality, and other hydrogeological maps. Not all of them are available in each of the participating countries (see chapter 6.5). Most of them are compiled and supplied by research institutes and some less by proper water and environmental authorities, the latter aimed essentially for decision making support in water management projects on different – local, regional, national or European – scale (Annex 1. Fig.6.). Extensive digital map databases existing in Holland (DINO) and Spain (XXXX) are not quite common in other participating countries but related database construction, its extension and the digital acquisition of printed paper maps is underway in each of them. In some countries hydrogeological maps are collected by geological Surveys, like in Austria, Sweden, Lithuania, Holland and Spain. They are stored and published in several institutions in others including Xxxxxx-Romagna Region (Italy), Hungary, the Czech Republic, the Slovak R...
Groundwater Quality. The District shall install one or more monitoring xxxxx downstream of the WRF. The well(s) shall be monitored for elevation of the groundwater table below the ground surface (bgs). If the groundwater table downstream of the WRF recharge site approaches 100 feet bgs, the District shall initiate pumping to control the groundwater level. The groundwater extracted may be discharged to the surface if the water quality is acceptable to the regulatory agencies, or it may be further treated and made available to the District’s domestic water supply system. The performance standard to be achieved is that the groundwater table downstream of the WRF recharge facilities shall not rise above the 100-foot bgse threshold. • The District shall install one or more monitoring xxxxx downstream of the WRF. The well(s) shall be monitored at least annually for all drinking water standards and compared to maximum contaminant levels (MCLs) for public drinking water standards. If concentrations approach any MCL, the District shall install additional treatment at the WRF to modify the treated effluent by lowering or removing the pollutant of concern to a level that will prevent the MCL from being exceeded. The performance standard to be achieved is that the groundwater quality shall not be allowed to exceed any MCL for a domestic or public drinking water supply. Habitat
Groundwater Quality. The purpose of this Annex is to gain a better understanding of how groundwater influences Great Lakes water quality and ecosystem health, and to identify priority areas for future action. Groundwater may represent as much as over 40 percent of the water entering the Great Lakes, either directly (via groundwater discharge along the coasts) or indirectly (via discharge into rivers and streams that then discharge into the lakes). As a result, the continued flow of good quality groundwater plays an important role in Great Lakes water quality and ecosystem health. Groundwater-transported contaminants and excessive nutrients can impair the quality of the waters of the Great Lakes, particularly the nearshore region, with potential effects on aquatic species, recreational waters and water supplies. Because groundwater is an important source of water and a potential source of contaminants and excessive nutrients and a pathway for transfer to the Great Lakes, groundwater quality is linked to the successful delivery of key commitments in other Annexes, including Areas of Concern, Lakewide Management, Harmful Pollutants, Nutrients, and Habitat and Species. Some areas near the Great Lakes are known to have contaminated groundwater. In some cases, initiatives are underway to direct management and/or implement remediation actions in these locations. They include numerous contaminated site risk assessment and remediation projects undertaken by private industry across the province, provincial contaminated site remediation efforts such as the Deloro Mine Site, and some of the work done through the Federal Contaminated Sites Action Plan, and the federal remediation of the Port Hope Area. These actions will protect or improve the water quality of the Great Lakes. This Annex includes commitments to update a binational state of groundwater science report, identify priorities for future research, and identify priority areas and sites for monitoring, management or remediation actions to address groundwater impacts and stressors.
Groundwater Quality. Devon anticipates developing a groundwater monitoring program for the Project according to the EPEA approval requirements. On the basis of other relevant programs, the Project program monitoring will most likely include twice-a-year sampling (spring and fall) from a network of shallow monitoring xxxxx. The function and location of each monitoring well will be approved by AEW, and an annual monitoring report will probably be requested by AEW. Devon will build the Project groundwater monitoring program using its experience with groundwater monitoring, the existing groundwater monitoring program for Jackfish, and the current regulatory requirements.
