Book Description

Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act - National Primary Drinking Water Regulations (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act - National Primary Drinking Water Regulations (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 This rule modifies the testing procedures approved for analysis and sampling under the Clean Water Act and Safe Drinking Water Act. EPA proposed these changes for public comment on August 18, 2003 and April 6, 2004. The Clean Water Act changes adopted in this final rule fall into the following categories: new vendor-developed methods as well as EPA and voluntary consensus standard bodies (VCSB) methods, updated versions of currently approved methods, revisions to method modification and analytical requirements, withdrawal of certain outdated methods, and changes to sample collection, preservation, and holding time requirements. This rule also changes regulations under the Safe Drinking Water Act that establish drinking water sampling and analysis procedures. The changes include approval of vendor-developed methods, new EPA and VCSB methods, updated VCSB methods, and approval of a modification to the test kit used with Syngenta Method AG-625 that restricts its use in certain circumstances. The addition of new and updated methods to the wastewater and drinking water regulations provides increased flexibility to the regulated community and laboratories in the selection of analytical methods.

Fluoride in Drinking Water


Book Description

Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.
