The Safe Drinking Water Act requires that utilities issue an annual “Consumer Confidence” Report to customers in addition to other notices that may be required by law. This report details where our water comes from, what it contains, and the risks our water testing and treatment are designed to prevent. The Calvert County Water and Sewerage Division is committed to providing you with the safest and most reliable water supply. Informed consumers are our best allies in maintaining safe drinking water.
