Stormwater management is a very recent term based on regulations passed in the 1990’s. American businesses such as scrap metal yards, gas stations & even car washes must comply with runoff water regulations, and must find innovative and cost effective ways to remove high PPM counts of harmful heavy metals such as lead, mercury, zinc, copper, cadmium, thallium and others; as well as fuel-based contaminants such as ammonium.
A recent court case in Oregon has resulted in new special protections for contaminated rivers and will now require more than 800 industrial sites such as lumber yards, scrap metal yards and truck depots to report their stormwater pollution four times per year instead of once.
Even now the recent Carr fires in Northern California are threatening the Sacramento River watershed.
Zeolite has been a proven heavy metal sequestration media for many years, and has been identified as a powerful filtration tool in the real world. In laboratory research, clinoptilolite has been shown to have a high absorption capacity, able to trap and adsorb harmful metals.
