PERFORMANCE VERIFICATION OF STORMWATER TREATMENT DEVICES UNDER EPA�S ENVIRONMENTAL TECHNOLOGY VERIFICATION PROGRAM
FREDERICK, R. M. AND T. STEVENS. PERFORMANCE VERIFICATION OF STORMWATER TREATMENT DEVICES UNDER EPA�S ENVIRONMENTAL TECHNOLOGY VERIFICATION PROGRAM. Presented at 2006 EPA Science Forum, Washington, DC, June 16 - 18, 2006.
The Environmental Technology Verification (ETV) Program was created to facilitate the deployment of innovative or improved environmental technologies through performance verification and dissemination of information. The program�s goal is to further environmental protection by accelerating the acceptance and use of improved and more cost-effective technologies. ETV seeks to achieve this goal by providing high-quality, peer-reviewed data on technology performance to those involved in the design, distribution, permitting, purchase, and use of environmental technologies.
The program works in partnership with recognized standards and testing organizations and with stakeholder groups consisting of federal, state, and local government representatives; consulting engineers; vendor organizations; and university researchers. All activities are conducted with the full participation of individual technology developers. The program evaluates the performance of innovative technologies by developing appropriate test plans, conducting field or laboratory tests, collecting and analyzing data, and preparing high quality peer-reviewed reports. All evaluations are conducted in accordance with rigorous quality assurance protocols to ensure the data are of adequate quality and the resulting technology verification reports are defensible.
NSF International, in cooperation with EPA, operates the ETV Program�s Water Quality Protection Center (WQPC), one of six technology centers in the ETV Program. The WQPC has evaluated the performance of eight stormwater treatment technologies designed to remove a variety of pollutants commonly found in stormwater runoff from roadways, parking lots, and vehicle maintenance areas. The technologies are generally compatible with existing storm sewer inlets and provide treatment by gravity or inertial separation or may contain a combination of screens and filter elements to trap pollutants. Field testing was conducted with full-scale commercial units, capturing runoff from 15 qualified storm events over a 15-month period using automated sampling equipment. Typical analyses included total dissolved solids (TDS); total suspended solids (TSS); suspended sediment concentration (SSC); total and dissolved phosphorus; oil and grease; chemical oxygen demand (COD); chloride; zinc, calcium, copper and magnesium; and sand fractionation.
Performance verification reports on these technologies are available to the public and posted on the ETV Program�s web site. This poster summarizes the performance of the tested devices and addresses some of the concerns of conducting extended field tests with these technologies.
