EPA has released the Containment and Disposal of Large Amounts of Contaminated Water: A Support Guide for Water Utilities. The guide serves as a reference document for the preparation and response to a contamination event when rapid decision making is needed. It provides recommendations primarily to drinking water, wastewater and stormwater utilities following an all-hazard chemical, biological, and radiological (CBR) contamination event. Secondary users of the guide are decision makers involved with planning and disposal at the federal, state, local and tribal levels. Click here for the guide.
