Drinking water in West Haven, Connecticut is delivered through 1 EPA-regulated community water system serving an estimated 69 people. Each system is tracked in the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act, which requires testing for regulated contaminants, consumer notification of violations, and publication of an annual Consumer Confidence Report.
