Toxicity Studies of Aquatic Actinomycetes

Description: Since Actinomycetes have been isolated from finished public drinking water, it is believed that the organisms are unaffected by the chlorination and flocculation of water treatment plants and pass as spores through the filters into the general distribution system. For this reason it was deemed imperative to study the toxic effects of these organisms.

Chemical, Physical, and Radiological Quality of Selected Public Water Supplies in Florida, November 1977-February 1978

Description: Abstract: Virtually all treated public water supplies sampled in Florida meet the National Inter-Primary and Proposed Secondary Drinking Water Regulations. These findings are based on a water-quality reconnaissance of 129 treated public supplies throughout the State during the period November 1977 through February 1978. While primary drinking water regulation exceedences were infrequent , lead, selenium, and gross alpha radioactivity in a very few water supplies were above established maximum contaminant levels. Additionally , the secondary drinking water regulation parameters--dissolved solids, chloride, sulfate, iron, color, and pH--were occasionally detected in excess of the proposed Federal regulations. The secondary regulations, however, pertain mainly to the aesthetic quality of drinking water and not directly to public health aspects.

Arsenic Water Technology Partnership Final Technical Report

Description: Congress created the Arsenic Water Technology Partnership (AWTP) in 2002 to develop and provide solutions for the cost-effective removal of arsenic from drinking water. The AWTP was funded by four congressional appropriations (FY03-FY06) to evaluate and develop new technologies that could significantly reduce compliance costs associated with the new 0.010 mg/L maximum contaminant level (MCL) for arsenic in drinking water. Initially focused on arsenic research, in FY06 the AWTP was expanded to include desalination research upon recognition that the research challenges were similar. The funding for the research and subsequent transfer of technology was made available by Congress through the Department of Energy (DOE). The AWTP was a collaborative effort between DOE’s Sandia National Laboratories (Sandia), Water Research Foundation (WaterRF, formerly Awwa Research Foundation) and WERC: A Consortium for Environmental Education and Technology Development based at New Mexico State University (WERC). Key features of the AWTP included technology development, technology implementation/testing and technology transfer. Each of the partners evaluated and oversaw development of new arsenic and desalination treatment technologies, and the technology transfer program ensured that successful technologies were transferred to the water supply community. Through the use of an arsenic treatment cost model, training sessions and a web site, information on arsenic removal and desalination technologies was transferred to stakeholders. KEY ACCOMPLISHMENTS The AWTP partnership funded research on, and deployment and testing of, innovative arsenic and desalination removal technologies; education for small and large water system operators; and development of a comprehensive web-based tool for arsenic treatment technology selection using site-specific data. As water becomes scarcer, and potable water supplies become increasingly vulnerable to contamination, the development of affordable water treatment systems is critical. Choosing the best available treatment system can be difficult. The AWTP has developed and evaluated improved arsenic and desalination treatment systems and provided that information ...

Drinking Water: The District of Columbia and Communities Nationwide Face Serious Challenges in Their Efforts to Safeguard Water Supplies

Description: Testimony issued by the Government Accountability Office with an abstract that begins "The discovery in 2004 of lead contamination in the District of Columbia's drinking water resulted in an administrative order between the Environmental Protection Agency (EPA) and the District's Water and Sewer Authority (WASA), requiring WASA to take a number of corrective actions. WASA also took additional, longer-term measures, most notably a roughly $400 million program to replace what may be 35,000 lead service lines in public space within its service area. As in WASA's case, water utilities nationwide are under increasing pressure to make significant investments to upgrade aging and deteriorating infrastructures, improve security, serve a growing population, and meet new regulatory requirements. In this context, GAO's testimony presents observations on (1) WASA's efforts to address lead contamination in light of its other pressing water infrastructure needs, and (2) the extent to which WASA's challenges are indicative of those facing water utilities nationwide. To address these issues, GAO relied primarily on its 2005 and 2006 reports on lead contamination in drinking water, as well as other recent GAO reports examining the nation's water infrastructure needs and strategies to address these needs."

Drinking Water: Safeguarding the District of Columbia's Supplies and Applying Lessons Learned to Other Systems

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Concerns have been raised about lead in District of Columbia drinking water and how those charged with ensuring the safety of this water have carried out their responsibilities. The 1991 Lead and Copper Rule (LCR) requires water systems to protect drinking water from lead by, among other things, chemically treating it to reduce its corrosiveness and by monitoring tap water samples for evidence of lead corrosion. If enough samples show corrosion, water systems officials are required to notify and educate the public on lead health risks and undertake additional efforts. The Washington Aqueduct, owned and operated by the U.S. Army Corps of Engineers, treats and sells water to the District of Columbia Water and Sewer Authority (WASA), which delivers water to D.C. residents. EPA's Philadelphia Office is charged with overseeing these agencies. GAO is examining (1) the current structure and level of coordination among key government entities that implement the Safe Drinking Water Act's regulations for lead in the District of Columbia, (2) how other drinking water systems conducted public notification and outreach, (3) the availability of data necessary to determine which adult and child populations are at greatest risk of exposure to elevated lead levels, and what information WASA is gathering to help track their health, and (4) the state of research on the health effects of lead exposure. The testimony discusses preliminary results of GAO's work. GAO will report in full at a later date."

Drinking Water: Experts' Views on How Federal Funding Can Best Be Spent To Improve Security

Description: Testimony issued by the Government Accountability Office with an abstract that begins "After the events of September 11, 2001, Congress appropriated over $140 million to help drinking water systems assess their vulnerabilities to terrorist threats and to develop response plans. Utilities are asking for additional funding, however, not only to plan security upgrades but also to support their implementation. This testimony is based on GAO's report, Drinking Water: Experts' Views on How Future Federal Funding Can Best Be Spent to Improve Security (GAO-04-29, October 31, 2003). Specifically, GAO sought experts' views on (1) the key security-related vulnerabilities affecting drinking water systems, (2) the criteria for determining how federal funds are allocated among drinking water systems to improve their security, and the methods by which those funds should be distributed, and (3) specific activities the federal government should support to improve drinking water security."

Drinking Water: Spending Constraints Could Affect States' Ability to Meet Increasing Program Requirements

Description: Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed the states' roles in implementing the Safe Drinking Water Act, focusing on: (1) how the Environmental Protection Agency's (EPA) budget requests for state program implementation compared to the amounts that are authorized and estimated to be needed; (2) how much the states have spent since the passage of the 1996 amendments to implement their drinking water programs and how their expenditures compare with estimated needs; (3) what effects federal funding levels have had, and could have in the future, on the states' ability to implement their programs; and (4) what existing practices have the potential to help the states implement their drinking water programs more effectively and efficiently."
