  • Combined use of rapid bioassessment protocols and sediment quality triad to assess stream quality

    Physical, chemical and biological conditions at five stations on a small southeastern stream were evaluated using the Rapid Bioassessment Protocols (RBP) and the Sediment Quality Triad (SQT) to assess potential biological impacts of a municipal wastewater treatment facility (WWTF) on downstream resources. Physical habitat, benthic macroinvertebrates and fish assemblages were impaired at Stations ...

  • Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water

    The U.S. Environmental Protection Agency is charged by Congress with protecting the Nation’s land, air, and water resources. Under a mandate of national environmental laws, the Agency strives to formulate and implement actions leading to a compatible balance between human activities and the ability of natural systems to support and nurture life. To meet these mandates, EPA’s research ...

  • Protocols for Evaluating the Effects of Land-use Patterns and Runoff Management on Urban Streams

    ABSTRACTThe design of urban runoff management facilities generally includes peak shaving for flood control, and best management practices (BMPs) for removing pollutants from the runoff. A number of scientists have concluded that the combination of these two control practices, which were developed independently of one another, is not sufficient to protect aquatic ecosystems. But these conclusions ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Barium Sulfate: A Protocol for Determining Higher Site-Specific Barium Cleanup Levels

    Abstract Although different barium compounds are known to exhibit vastly different toxicities, cleanup standards for barium in soil or sediment at environmental corrective action sites are typically based on total barium concentration without regard for the specific barium compounds present. However, the Texas Commission on Environmental Quality (TCEQ) has recently agreed that the insoluble ...


  • Modification of jar testing protocol combined with mEnCo model predicted dose to predict dissolved organic matter removal for surface water

    In recent climatic events in Australia, the need for frequent jar testing to determine optimum coagulant and flocculant aid doses became apparent in order to determine optimum treatment efficiencies. The generally applied jar test procedure can be time consuming and this prompted investigations for capacity to test waters more rapidly, for a range of treatment conditions and raw water qualities. ...

  • Water quality products magazine features ITS

    The decision for a company to seek approval from the U.S. Environmental Protection Agency (EPA) on a product can be beneficial in the long run, but the road to get there may be a long one. In August 1998, Industrial Test Systems (ITS) began its journey on the path to EPA approval for its Sensafe Free Chlorine Water Check test strips. After many outside studies, research, testing and reporting, ...

  • Soil Sampling Protocol to Certify the Changes of Organic Carbon Stock in Mineral Soils of European Union

    The Kyoto Protocol (UNFCCC, 1998) considers soils as an essential component to mitigate the increasing concentrations of greenhouse gases in the atmosphere. Two additional reports: (1) Land Use, Land-Use Change, and Forestry (LULUCF) (IPCC, 2000) and (2) Good Practice Guidance for LULUCF (IPCC, 2003) identify soil organic carbon (SOC) monitoring to be an obligatory tool when implementing Articles ...


  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Methodology for Forensic Investigation of Potable Water Quality in Municipal Distribution Systems

    Abstract During routine regulatory potable water quality sampling in distribution systems related to the Total Coliform Rule, utilities can sometimes experience anomalous detections of total coliform bacteria and/or fecal coliform bacteria in the distribution system samples. Frequently, the regulatory-required retesting of the same sample locations reveals no detection of bacteria, and thus ...

  • Determination of antimony in bottled water and polyethylene terephthalate bottles: a routine laboratory quality check

    The paper describes a modified and optimised conventional wet ashing method for the determination of antimony (Sb) in polyethylene terephthalate (PET) bottles used for bottling sparkling and still water. The modified optimum conventional wet ashing method was applied as the digestion method to extract Sb from PET bottles, and the extracted Sb analysed using flame atomic absorption spectrometry ...

  • Remote Sensing Techniques to detect Surface Water Quality Constituents in Coastal and Inland Water Bodies from Point or Non Point Pollution Sources

    This study demonstrates that point and non-point pollution sources in coastal and inland water bodies can be identified and monitored using remote sensing techniques so early corrective action can be take to prevent or minimize Harmful Algae Blooms (HAB’s). By tracking these changes in the remote sensing images could be very beneficial in establishing cleanup and restoration efforts for improving ...

  • In-situ quality monitoring station in Lower Saxony

    Background 'Duemmer' is a shallow lake in the south-west of Lower Saxony; through the lake flows the river 'Hunte'. The catchment area spans 426 km2. With a surface of 12.4 km2 and an average depth of 1.1 m there is a water volume of approx. 14 million m3. Large parts of the lakeside are a nature reserve and the lake is a popular local recreation area. The lake suffers from strong nutrient ...

  • Determination of Groundwater Quality Index of a Highland Village of Kerala (India) Using Geographical Information System

    In this study, the authors’ goal was to understand the groundwater quality of Nedumkandam panchayat by an integrated approach of traditional water quality analysis and Geographical Information Systems (GIS). Fourteen wells were identified from the study area and samples were collected and analyzed using standard protocols (American Public Health Association, 1998). Parameters analyzed include pH, ...

  • Determination of oil and grease in water with a mid-infrared spectrometer

    The concentration of dispersed oil and grease (OG) is an important parameter for water quality and safety. OG in water can cause surface films and shoreline deposits leading to environmental degradation, and can induce human health risks when discharged in surface or ground waters. Additionally, OG may interfere with aerobic and anaerobic biological processes and lead to decreased wastewater ...

  • iTOXcontrol Safeguards Intake Romanian Drinking Water

    The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company ...

  • Assessment of rainwater harvesting for drinking water supply in Bangladesh

    Rainwater harvesting is a potential option of water supply to the coastal and arsenic affected rural communities in Bangladesh and during the last few years, several projects were undertaken to promote and install various types of rainwater harvesting systems by government organizations and NGOs mainly for drinking and cooking water supply. A study was undertaken to assess the currently practiced ...
