Water Pollution: Proposed Pretreatment Standards for Industrial Laundries

Water Pollution: Proposed Pretreatment Standards for Industrial Laundries

Date: January 20, 1999
Creator: United States. General Accounting Office.
Description: Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the dispute between the Environmental Protection Agency (EPA) and the industrial laundry industry regarding EPA's cost benefit analyses of its proposed pretreatment standards, focusing on: (1) EPA's implementation of the Unfunded Mandates Reform Act of 1995 (UMRA); (2) the significant differences between EPA's and the industry's cost estimates of this proposed regulation; (3) ascertaining how EPA estimated the benefits of the proposed rule and disclosed the uncertainties associated with the accuracy of its estimates; and (4) how EPA's analysis supports its belief that the agency has chosen the least costly, most cost-effective, or least burdensome regulatory alternative."

Concentrations of Triclosan in the City of Denton Wastewater Treatment Plant, Pecan Creek, and the Influent and Effluent of an Experimental Constructed Wetland

Concentrations of Triclosan in the City of Denton Wastewater Treatment Plant, Pecan Creek, and the Influent and Effluent of an Experimental Constructed Wetland

Date: August 2004
Creator: Waltman, Elise Lyn
Description: The Pecan Creek Waste Reclamation Plant in Denton, Texas, an activated sludge WWTP, was sampled monthly for ten months to determine seasonal and site variation in concentrations of triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol), an antibacterial additive. SNK separation after the highly significant ANOVA on ranked data were: summer = fall > winter = spring and influent > downstream = effluent = wetland inflow > wetland outflow (a=0.05). After the plant converted to ultraviolet disinfection, measurements were made before and after the UV basin to determine if significant amounts of triclosan were converted to dioxin. Percent loss at each of the treatment steps was determined. Concentrations of triclosan in the downstream site were below the published NOEC for the most sensitive species.

Federal Water Pollution Control Act

Federal Water Pollution Control Act

Date: November 27, 2002
Creator: United States. Congress. House
Description: The Clean Water Act (CWA) establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating quality standards for surface waters. The basis of the CWA was enacted in 1948 and was called the Federal Water Pollution Control Act, but the Act was significantly reorganized and expanded in 1972. "Clean Water Act" became the Act's common name with amendments in 1977. Under the CWA, EPA has implemented pollution control programs such as setting wastewater standards for industry. We have also set water quality standards for all contaminants in surface waters. The CWA made it unlawful to discharge any pollutant from a point source into navigable waters, unless a permit was obtained. EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls discharges. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters.

Water Pollution: EPA Has Improved Its Review of Effluent Guidelines but Could Benefit from More Information on Treatment Technologies

Water Pollution: EPA Has Improved Its Review of Effluent Guidelines but Could Benefit from More Information on Treatment Technologies

Date: September 10, 2012
Creator: United States. Government Accountability Office.
Description: A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) uses a two-phase process to identify industrial categories potentially needing new or revised effluent guidelines to help reduce their pollutant discharges. EPA’s 2002 draft Strategy for National Clean Water Industrial Regulations was the foundation for EPA’s process. In the first, or “screening,” phase, EPA uses data from two EPA databases to rank industrial categories according to the total toxicity of their wastewater. Using this ranking, public comments, and other considerations, EPA has identified relatively few industrial categories posing the highest hazard for the next, or “further review,” phase. In this further review phase, EPA evaluates the categories to identify those that are appropriate for new or revised guidelines because treatment technologies are available to reduce pollutant discharges. Since 2003, EPA has regularly screened the 58 categories for which it has issued effluent guidelines, as well as some potential new industrial categories, and it has identified 12 categories for its further review phase. Of these 12 categories, EPA selected 3 for updated or new effluent guidelines. EPA chose not to set new guidelines for the others."

How Healthy is the Upper Trinity River?: Biological and Water Quality Perspectives

How Healthy is the Upper Trinity River?: Biological and Water Quality Perspectives

Date: 1990
Creator: Jensen, Ric
Description: This conference report contains discussions and papers from a symposium hosted at Texas Christian University, in Fort Worth, Texas, examining the ecological health of the Upper Trinity River, and the impacts of various human activity, such as agriculture, urbanization, and waste management. The papers cover the effect of water quality on urban rivers, long-term water quality trends in the Trinity River, solutions that may improve water quality in the river, as well as biological, agricultural and waste-water issues.
