Water Microbiology

In total, 15 Norwalk beaches are tested for bacteriological water quality weekly (and more often as necessary) from Memorial Day through Labor Day. Click here to see the swimming status of these beaches.

Also, well water is tested for portability on a fee-for-service basis. A well water test kit can be picked up and returned to the Health Department reception desk during normal operating hours. Results are available in 24 hours. Click here for fees.

Tick Identification

Citizens should bring ticks to the Health Department during normal operating hours for identification. Ticks are screened by the laboratory, and those identified as deer ticks are sent to the Connecticut State Agricultural Experiment Station for Lyme disease testing. This service carries a nominal fee for non-Norwalk residents. Click here for fees.

Sexually Transmitted Disease Diagnostic Testing

The Laboratory supports the Sexually Transmitted Disease Clinic by providing clinical testing and specimen referral related to the diagnosis of STDs. Click here for the hours of operation of the STD Clinic.
