  • Antibiotics in groundwater under locations with high livestock density in Germany

    Antibiotics are deployed in large quantities both in human and in veterinary medicine. Studies show that antibiotic residues occur in the environment (e.g. soil and surface waters). In some cases they were also detected in ground and drinking water. However, the degree of groundwater pollution by antibiotic residues from livestock farming is unknown. Therefore, the federal environment agency ...

  • Radon distribution in groundwater of Taiwan

    Radon levels were surveyed in 517 monitoring wells constructed in five major groundwater areas of Taiwan. The radon concentration in groundwater samples varied in a wide range from below the detection limit of 18 pCi/L up to 1,100 pCi/L. A worldwide comparison of reported groundwater radon levels was conducted. Overall radon levels in Taiwan groundwater are relatively low compared to other ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • Dynamics of nitrate & perchlorate in groundwater.

    The Apache Powder Superfund Site is located in Cochise County, Arizona, approximately 50 miles southeast of Tucson. The site was listed on the National Priorities List pursuant to CERCLA in 1990. Principal groundwater chemicals of concern (COCs) include nitrate-nitrogen (nitrate-N) and perchlorate. Concentrations of nitrate-N exceeding 500 mg/l and 2,300 mg/l have been detected in the “shallow ...

  • Comparative Effects of HRC Application at Four Project Locations (PDF)

    Four site locations in the Southern or Midwest United States were the venues for pilot testing of a commercially available injectable bioremediation product (HRC™) to enhance the reductive dechlorination of chlorinated solvents. This activity occurred from 1997 through the end of 2000. Prior to injection, each site exhibited bioattenuation of parent compounds such as PCE, TCE, carbon ...

  • Case study - Chlorinated groundwater treatment

    Problem A Fortune 50 company implemented a remedial project to collect and treat polluted groundwater from a site in Central New York, preventing the mitigation of impacted groundwater from flowing into local waterways. An engineering and construction firm was hired to design and build an effective, efficient groundwater treatment system. Collection of the polluted water would be done ...

  • Case study: URS - Identifying remediation locations saved hundreds of thousands

    One of the biggest threats to public health today is unsafe water. A billion people across the world don’t have access to clean drinking water, in part because many subsurface aquifers have been poisoned. Perhaps the most famous example of this was the Love Canal crisis of 1978. The Niagara Falls neighborhood experienced high rates of cancer, birth defects and other sicknesses due to ...
