Safe Drinking Water Act: EPA Should Improve Implementation of Requirements on Whether to Regulate Additional Contaminants

Safe Drinking Water Act: EPA Should Improve Implementation of Requirements on Whether to Regulate Additional Contaminants

ISBN: 9781437988680

Under 1996 amendments to the Safe Drinking Water Act (SDWA), every 5 years the EPA is to determine for at least five contaminants, such as chemicals, whether regulation is warranted, considering those that present the greatest public health concern.

Since 1996, EPA had not recommended any new contaminants for regulation until Feb. 2011, when it reversed its controversial 2008 preliminary decision to not regulate perchlorate, an ingredient in rocket fuel and other products. This report: (1) evaluates the extent to which EPA’s implementation of the 1996 amendments has helped assure the public of safe drinking water; and (2) reviews the process and scientific analyses used to develop the 2008 regulatory determination on perchlorate. Illus. A print on demand report.

New Government Report: Managing Coal Combustion Waste (CCW): Issues with Disposal and Waste

Managing Coal Combustion Waste (CCW): Issues with Disposal and Waste
by Linda Luther (Paperback, 26 pages, $20)

In 2008, coal-fired power plants accounted for almost half of the U.S.’ electric power, resulting in as much as 136 millions tons of coal combustion waste (CCW). CCW generally contains a range of heavy metals such as arsenic, beryllium, chromium, lead, and mercury.

While there is the potential for a sudden catastrophic release of waste, the primary concern regarding the management of CCW usually relates to the potential for hazardous constituents to leach into surface or groundwater, and hence contaminate drinking water, surface water, or living organisms.

Contents of this report: (I) Overview of Disposal and Use Issues; (II) The Nature of Coal Combustion Waste; (III) Potential Risks Associated with CCW Management; (IV) Regulatory History and Current Rulemaking: Waste Management Requirements Potentially Related to CCW; CCW’s Regulatory Exemption Under “the Bevill Amendment”; EPA Actions from the Bevill Amendment to Kingston.
