  • Encouraging results in evaluating groundwater contaminants

    The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

  • Midwest groundwater tainted with sewage and chemicals

    Raw sewage is flowing into rivers and streams across central and eastern Iowa as one after another wastewater facilities are inundated by the record floods that have swept the state during the past two weeks. Livestock manure is also part of the nasty mix, along with spilled fuel and chemicals, all heading to the flooding Mississippi River and down to the Gulf of Mexico. The U.S. Environmental ...

  • ZZ conducted pollution mapping (sulphur) IP survey in Brukunga, South Australia

    ZZ participated in pollution mapping at an abandoned mine site in South Australia. The scope of the survey is to find the sulphur development direction, so preventive method could be used to stop the sulphur get into the groundwater.  Over 9 survey lines were laid in two days to cover the survey area. On site drillings were followed up after the resistivity survey and concurred with our ...

  • Bacterial remediation of groundwater depends on environmental conditions

    New low cost methods using bacteria to remove toxic metals from groundwater have been investigated using both actual contaminated groundwater and artificially controlled systems. Environmental conditions, such as changing levels of acidity or alkalinity, can have a significant effect on the removal of toxins, results show. Contamination of soils and groundwater with toxic metals, such as lead and ...

  • Mapping groundwater flooding for the EU Floods Directive

    In the coming years the EU Floods Directive1 will require Member States to produce flood hazard and risk maps. Taking the UK as a case study, new research highlights the need for advances in data collection, mapping and groundwater flood warning systems to meet EU requirements for maps and management plans. Although often occurring less frequently than fluvial (river) flooding, the effects of ...

  • EPA Settlement Protects Soil and Groundwater in Lawrence, Mass.

    In a recent settlement agreement with EPA’s New England office, Hilton Oil Co., Inc. will take action to come into compliance with Underground Storage Tank regulations to protect groundwater and soil at its facility in Lawrence, Mass.
