Water Headlines for August 24, 2006Benjamin H. Grumbles Water Headlines is a weekly on-line publication that announces publications, policies, and activities of the U.S. Environmental Protection Agency’s Office of Water. In This Week’s Water Headlines:
New Guidance to Help Public Water Systems Evaluate Treatment ChangesEPA is releasing a draft guidance to help public water systems as they make operational changes to comply with drinking water regulations that control microbial contaminants and disinfection byproducts. As they work to provide safe drinking water, operators of public water systems must evaluate the effects that changes in the treatment process could have on their ability to meet multiple drinking water standards. "This is an important step in completing our lead reduction action plan and helping utilities meet existing and new requirements under the Safe Drinking Water Act," said Benjamin H. Grumbles, Assistant Administrator for Water. The failure to carefully consider these effects can result in problems that affect public health. For example, treatment changes to reduce disinfection byproducts could increase the corrosivity of drinking water, which, in the absence of adequate corrosion control, could result in an increase in lead in drinking water. New Report on Emerging Technologies for Conveyance SystemsA new technology guide for municipal and utility collection system owners and operators is available from the EPA. The guide provides information about innovative and emerging technologies for the installation and repair of new and existing conveyance systems. The nation's conveyance system is comprised of over 21,000 collections systems accounting for more than 750,000 miles for publicly owned sanitary and combined sewers and 500,000 miles of privately owned sewers. “This useful information will help advance our sustainable infrastructure agenda,” said Benjamin H. Grumbles, Assistant Administrator for Water. The guide classifies the state of development for each technology as established, innovative, or embryonic and provides a Technology Summary Fact Sheet for each innovative and embryonic process with information describing the technology, cost data, contact information, and data sources. The guide also includes data on cost-effective technologies for repair and rehabilitation of existing conveyance systems and preliminary information on emerging technologies for new installations and for the repair of existing conveyance systems. The use of these cost effective technologies may extend the service life of the existing collection system or greatly reducing the replacement, repair, operation, and maintenance costs for municipal utilities across the country. For a copy of the report, visit the publications section on the OWM Municipal Technologies web site at: www.epa.gov/owm/mtb. AQUATOX Training Workshop in Philadelphia, October 2006EPA is sponsoring an AQUATOX training workshop on October 24-26 in Philadelphia. AQUATOX is a PC-based simulation model for aquatic ecosystems that covers eutrophication, chemical fate, bioaccumulation, and ecotoxicology. The course is a detailed overview of the model that allows ample time to work with it in a lab setting. There is no charge for the workshop, but attendance is limited. We require that you register before the course. You can get more information at our AQUATOX training page on the Internet at www.epa.gov/waterscience/models/aquatox/training/.
