Well water quality depends on many factors including: soil and rock types, local land uses, and well type. Well water quality can change over time; so make sure yours is safe to drink. Ensure accuracy of results by using licensed private well samplers, labs, and interpreters.
The following tests are recommended for existing well maintenance and some are required by Rhode Island law to be performed for new wells, certificates of occupancy, or property transfers. Required tests are italicized.
Depending on soil and land use conditions where you well is located, you may need to do additional well-water tests. In addition, make sure to check your city or town ordinances for other required tests.
If a well is near a known source of groundwater contamination it should be tested for chemicals that may be present at elevated levels. In particular, the Department of Health recommends testing for Beryllium in areas where the bedrock is close to the surface and for Arsenic in areas where there are, or have been orchards as that element has been used in pesticides. Use the private well testing tool to determine which tests you should run for your location more.
