State and federal drinking water rules require Group A
community water systems to produce and distribute an annual "Consumer
Confidence Report" (CCR) to customers by July 1st of each year. A CCR is
a yearly report on the quality and safety of the system's drinking
water. It includes the most recent results of water quality tests the
system conducted over the last five years (not all tests are required
every year). It also provides access through references and telephone
numbers to source water assessments, health effects data and additional
information about the water system.
