Suggested Practices to Reduce Zinc Concentrations in Industrial Stormwater Discharges
Source: Washington Department of Ecology
Description: “Ecology prepared this document to help you reduce zinc in your stormwater discharge. The idea is to use source control measures. Source control is removing or covering sources of zinc before they become part of stormwater runoff. This is often more effective than trying to remove zinc once it is in the stormwater. Methods for treating stormwater may be found elsewhere. This guide covers sources of zinc and tells you how to remove or reduce them.” – From summary page
