StormwateRx was approached by AECOM, the #1 ranked global design firm by Engineering News Record (ENR) magazine in July 2016, to solve a lingering stormwater zinc pollutant problem at a lubricating oil distribution facility operated by the largest publicly traded international oil and gas company in the world. The Pacific Northwest facility had been retrofit with a failed stormwater treatment system by a prior consultant and was under a corrective action order by the state Department of Environmental Quality to reduce zinc concentrations in stormwater runoff to below the benchmark of 120 ug/L zinc.

StormwateRx worked with the engineer, local and Corporate environmental and facilities staff to size and locate Aquip Zinc-B-Gone stormwater treatment for the 1.1 acre warehouse facility. The building was retrofit with new gutters to consolidate flows to two Aquip Zinc-B-Gone Max 50 advanced stormwater polishing filters. The fully passive Zinc-B-Gone filters treat stormwater in a two-step process – first to remove particulates and debris, and second to remove dissolved zinc and other metals to very low residual levels. The Aquip Zinc-B-Gone process is highly effective and effluent stormwater quality from the systems have been well below the benchmarks since the filters were put online.
