Why test for VOCs in Connecticut
Volatile organic compounds come from fuel, solvents and their breakdown products, and because they evaporate they reach you through the shower as well as the tap. Read our VOCs explainer.
Connecticut guidance that mentions VOCs:
- Connecticut's health department guidance, as summarized by the state legislature's research office in 2019: basic indicators every year; lead at least once; arsenic, uranium and radon at least once and ideally every five years; VOCs at least once. [1]
About 861,472 people in Connecticut used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [2] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Connecticut.
