Cost and Performance Report Low Impact Technologies to Reduce Pollution from Storm Water Runoff SI-200405

摘要

This project was to validate the performance of a dual media filtration system that removes metals, organic compounds, and sediment found in storm water runoff from DoD industrial sites. Full-scale demonstrations were conducted at the Navy Regional Recycling Center (NRRC) in San Diego, CA and the Anniston Army Dept (ANAD) in Anniston, Alabama. The specific performance goal at NRRC was to meet the NPDES storm water permit by passing acute toxicity requirements, and by reducing copper and zinc to less that 63.6 ug/l and 117 ug/l respectively. All of the acute toxicity test requirements were met 100% of the time for the last 5 storm events, after slight modification to the media bed. The average removal efficiencies for the last five storm events of the test period met the permit requirements for aluminum, copper, and lead, and was within 3% of the 117 ug/l limit for zinc. The dual media filtration system met the performance goal at ANAD. No sheen, visible oil, floating solids, or visible foam was reported in the dual media storm water filters effluent during throughtout the demonstration period.
