Abstract:

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, California and the Anniston Army Depot 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 than 63.6 micron gl and 117 micron gl 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 percent of the 117 micron gl 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 throughout the demonstration period.
