Application of Enhanced Treatment Strategies for Soluble Metals in the San Diego Region

Heavy metals are particularly challenging pollutant constituents associated with highway and local road runoff. Automobiles are among the most significant source of zinc and copper found in the environment due to the wear-down of brake pads and tires. During precipitation these constituents can become soluble, making them difficult to impossible to effectively treat without BMP processes aided by infiltration. In many instances and locations, it is impractical or impossible to construct conventional best management practices (BMPs) such as swales, bioretention, and extended detention facilities capable of permitting significant infiltration. In such instances, the transport of soluble metals from highway areas to the receiving waters cannot successfully be mitigated.
The presenter will summarize recent findings from the National Cooperative Highway Research Program (NCHRP) regarding the sources, transport, and fate of soluble metals in the highway environment and present several concept design alternatives for a structural BMP that specifically targets soluble metals. In addition to effectiveness in treating soluble metals, these concepts have been developed with suitability for highway construction and retrofit as the primary characteristics. The presenter will also examine the application of this enhanced treatment approach within a San Diego watershed. The analysis will include a case study hydrology model that incorporates local parameters and cost information from NCHRP research. The case study will be used to demonstrate feasibility and pollutant load removal from the local environment.
