Groundwater long-term monitoring (LTM) is required to assess human health and environmental risk of residual contaminants after active groundwater remediation activities are completed. However, LTM can be costly because of the large number of sampling locations that exist at a site from previous site characterization and remediation activities. The cost of LTM may be reduced by identifying redu...

a r t i c l e i n f o Land has been reclaimed along the coastal areas in many parts of the world to meet the growing demand for houses and other land use. Over 15 km 2 of land has been reclaimed around the Shekou peninsula, Shenzhen, China. Land reclamation may have significant influences on groundwater systems but this problem has not been adequately studied. Using FEFLOW (Diersch, 2005), a th...

Remedial enhancements to an existing pump-and-treat (P&T) system were selected for a pilot study to address trichloroethene (TCE)-impacted groundwater within a fractured bedrock system extending into a residential neighborhood. The focus for implementing the remedial enhancements was the farthest downgradient area of the dissolved plume not fully responding to P&T system operations due to pumpi...

groundwater is a major source of water for domestic, industrial, and agricultural sectors in many countries. the main objective of this research was to provide an overview of present groundwater quality using parameters such as calcium, magnesium, sodium, chloride, sulfate, ph, and electrical conductivity (ec) in the mehran plain, ilam province using gis and geostatistical techniques. a total o...

Water and gas samples were collected from (1) nine shallow groundwater aquifers overlying Marcellus Shale in north-central West Virginia before active shale gas drilling, (2) wells producing gas from Upper Devonian sands and Middle Devonian Marcellus Shale in southwestern Pennsylvania, (3) coal-mine water discharges in southwestern Pennsylvania, and (4) streams in southwestern Pennsylvania and ...

As a developing country the protection of groundwater resources is extremely important in India. Landfills are a major source of water pollution. The filling for the disposal site in Ahmedabad, occurs at a distance of about 50 meters from Ahmedabad plant water intake. In addition, there are several holes are near the tip, which is used for drinking and domestic use. A survey of the composition ...

Groundwater contamination is a serious problem facing the countries. Because groundwater is vulnerable to contamination from a variety of sources, and, once contaminated, it is very difficult to restore to its original quality. The main objective of this study was evaluation of groundwater quality in Shahrekord aquifer and finding the source of the groundwater contamination. Some of the chemica...

Measurements were made of the nitrate concentration and bacterial contamination of groundwater samples taken from both dug wells and bores in the commune of Hop Thinh', in the administrative district of Vinh Phuc, Vietnam. A significant number (18%) of samples had nitrate concentrations in excess of the WHO Guideline value for drinking water of 50 mg L(-1), with a higher proportion in the dug w...
