The NYS Health Department recommends that you test your well water at least once a year for bacteria, and every 3-5 years for other contaminants.
The most basic test for bacterial contamination of a water supply is the test for total coliform bacteria. The total coliform count provides a general indication of the sanitary condition of your water supply.
The Oswego County Health Department offers water testing for coliform bacteria through the Oswego Residential Well Assistance Program. The cost of this program is $30. You will receive verbal results whether your water tested positive or negative for coliform bacteria.
The Environmental Health Division also offers Realty Water Testing for property transactions. The cost is $75, and we will provide you with written results.
If you are interested in either of these programs, call 315-349-3557. Environmental staff will guide you through the process. Refer to the instruction sheet for more information. Please note that water samples can only be accepted Monday through Thursday from 8:30 a.m. to 12:30 p.m.
