Field Trials of BMP to Remove Dissolved Metals in Highway Runoff

The recently published National Cooperative Highway Research Program (NCHRP) Report 767: Measuring and Removing Dissolved Metals from Stormwater in Highly Urbanized Areas (NCHRP Project 25-32) developed a number of designs of facilities for the removal of dissolved metals in highway runoff in ultra-urban areas, as well as a laboratory protocol to evaluate the potential of various media to remove dissolved metals. That research did not include a field testing component to evaluate either the functionality of the designs or validate the laboratory protocol. The objectives of this project are to achieve both of those goals, so that departments of transportation (DOTs) can implement the designs with the sure knowledge of their cost effectiveness. The purpose of the proposed field trials is to evaluate dissolved metal removal rates, assess operational functioning under actual highway conditions, and develop actual cost information, so that DOTs have reliable data to support implementation decisions. Potential tasks include (1) selection of installation location, (2) construction of the treatment facility, (3) water quality monitoring for up to a year, (4) whole-life cost assessment and, (6) final report development. Dissolved metals in highway runoff frequently exceed water quality standards; consequently, DOTs are under regulatory pressure in many areas to reduce the concentrations of these constituents. Without field testing the recommendations contained in NCHRP Report 767, the money and effort that went into that project will be largely lost. Consequently, the proposed work is a necessary follow up to that previous work. Note: The American Association of State Highway and Transportation Officials (AASHTO) Standing Committee on Research suggests that the emphasis of this research be placed on deployment.
