  • Linking drugs of abuse in wastewater to contamination of surface and drinking water

    The concentrations of 17 drugs of abuse, including cocaine, several amphetamines, opioid drugs, and 2 metabolites—benzoylecgonine, a metabolite of cocaine, and 2‐ethylidene‐1,5‐dimethyl‐3,3‐diphenylpyrolidine, a metabolite of methadone—were investigated in an urban watershed that is heavily impacted by discharges of municipal wastewater. The artificial sweetener sucralose was also monitored as ...

  • Using PRTR database for the assessment of surface water risk and improvement of monitoring in Japan

    In April 2003, the first PRTR (Pollutant Release and Transfer Register) was published in Japan. It is shown how the PRTR can be used to improve environmental risk assessment with the objective of reducing risk to ecosystem integrity and human health. By examining the superposition of all chemical releases into rivers, high levels of several contaminants are uncovered. Most of these chemicals have ...

  • Comparison of Monitoring Approaches for Selected Priority Pollutants in Surface Water

    1 AbstractLaboratories from seven EU Member States under the coordination of the Joint Research Centre and in collaboration with the Provincia di Ferrara participated in a technical on-site project during which sampling and analytical methodologies for chemical monitoring according to proposed WFD provisions have been compared. Laboratories had been invited to take samples from a river according ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • Containment for Ground Water, Surface Water, And Leachate

    Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Transport of a nematicide in surface and groundwaters in a tropical volcanic catchment

    Received for publication August 7, 2008. The aim of this article is to determine how the nematicide cadusafos [S,S-di-sec-butyl O-ethyl phosphorodithioate] contaminates water and soils at two scales, subcatchment and catchment. The study site was a small banana (Musa spp.)-growing catchment on the tropical volcanic island of Guadeloupe in the Caribbean. Two application campaigns were conducted, ...

  • Surface water Sulfate dynamics in the northern Florida everglades

    Received for publication August 24, 2007. Sulfate contamination has been identified as a serious environmental issue in the Everglades ecosystem. However, it has received less attention compared to P enrichment. Sulfate enters the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Refuge), a remnant of the historic Everglades, in pumped stormwater discharges with a mean concentration of ...

  • Feasibility assessment of surface water disinfection by ultrafiltration

    Ultrafiltration (UF) has been presented as an alternative to chemical disinfection to obtain safe drinking water, for its ability to remove microbiological contamination. Hollow-fiber UF membranes are designed as an effective barrier to microorganisms, for their high manufacturing integrity and for the ‘potting’ method adopted to seal fibers to the feeding/extraction manifold. ...

  • Scientific And Regulatory Perspectives On The Emerging Environmental Contaminants Issue

    ABSTRACTEmerging environmental contaminants include a wide variety of chemicals that have been largely outside of the scope of environmental regulation.  Also referred to as PPCPs (pharmaceuticals and personal care products), these contaminants are derived from any product consumed by humans or animals for health or cosmetic reasons, and thus include prescription and non-prescription human ...

  • Bioswales reduce contaminants associated with toxicity in urban stormwater

    Contamination and toxicity associated with urban stormwater runoff are a growing concern because of the potential for receiving system impacts. California water regulators are mandating implementation of green infrastructure as part of new urban development projects to treat stormwater and increase infiltration. Parking lot bioswales are low impact development practices that promote filtering ...

  • Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

  • Quantitative risk assessment for contaminated sites in Spain

    Environmental Quantitative Risk Assessment is one of the key factors in the Decision Making Process for contaminated sites. Numerous decisions have to be made before, during and after conducting a quantitative risk assessment.Risk assessment is based on the information gathered previously: Historical information (Phase I) Site characterization (Phase II) Toxicological ...
