Laboratory Testing

The Environmental Health Unit maintains its own water bacteria testing laboratory for public and private water supplies. The laboratory is New York State and Environmental Protection Agency (EPA) approved and certified to test potable (drinking) water and non-potable (lakes, ponds, streams) water for Total Coliform and E.coli bacteria.

Locations and hours are listed on the right.

Routine Testing
The Health Department routinely tests all community (cities, villages, mobile home parks) and non-community (restaurants, hotels) water supplies to ensure that Total Coliform and E.coli levels are absent. 

Private Water System Testing
The Health Department also tests private water systems (homes and businesses) primarily when the homes are being sold or when a private homeowner requests a bacteria test be performed. 

Public Water Testing
The Health Department routinely tests public bathing beach water, lakes, pond and streams for a safe level of the Total Coliform and E. Coli bacteria.

Test Results
Water test results will be available within 48 hours of sample submission.

Why Test for Bacteria
Total Coliform and E. Coli bacteria is a group of bacteria that lives in the intestinal tract of all warm blooded animals (birds, cats, dogs, humans, etc.) Since this bacteria lives in humans naturally, this alone usually will not make people ill. However, the presence of this bacteria in water indicates that the water has been in contact with fecal matter and the many viruses and bacteria that can cause illness.
