Well water testing in Dutchess County, New York
About half of Dutchess County residents get water from household wells. The county health department tested hundreds of private wells in 2007–08, three towns require well testing when a home sells, and the state offers free PFAS testing here. Every fact has a source.
How many people here use a private well
USGS estimates that about 145,000 people in Dutchess County supplied their own household water in 2015, about 49% of the county's population.1
The county health department says private wells aren't regulated by EPA, New York State or the county, so testing is up to the owner.2
Buying a home with a well in Dutchess County
- Town laws: the Dutchess County Department of Behavioral & Community Health (DBCH) says the Towns of East Fishkill, Fishkill and Wappinger have local laws requiring well water testing in real estate transactions.2 Ask the town for the current requirements and test list.
- State disclosure: New York's Property Condition Disclosure Statement asks the seller the water source and whether water quality or flow rate has been tested.5
- Elsewhere in the county, no test is required. Write a well inspection and water test contingency into your offer. Our homebuyer's guide covers what to include.
What countywide testing found
In 2007–08, the county health department ran a countywide private well testing initiative. In its Phase II report (September 2009), the county said:3
- Sodium was the most commonly detected substance. The county pointed to water softener backwash and road salt as likely sources.
- Total coliform bacteria was the next most common.
- No principal organic compounds or MTBE were found above drinking water standards.
The county publishes a database of private well test results.4
What to test and how often
The New York State Department of Health (NYSDOH) recommends testing for bacteria every year, and every 3–5 years for lead, nitrate/nitrite, arsenic, sodium, iron/manganese, turbidity, pH, hardness and alkalinity. Late spring or early summer is the best time.6 NYSDOH suggests extra tests depending on nearby activities, such as volatile organic compounds near fuel storage.7
Free PFAS testing
Dutchess County is one of six counties in NYSDOH's private well PFAS testing pilot, which offers free testing to eligible homes. If PFOA or PFOS is 10 ng/L or more, rebates are up to $5,000 for whole-house treatment, $1,000 for point-of-use treatment, or $10,000 for connecting to public water.8 Check eligibility on the program page.
