Drinking water: probably a private well

No community water system’s service area covers the center of ZIP 33587, and no system lists it. In rural areas that usually means private wells. The EPA does not regulate private wells: owners should test once a year for coliform bacteria and nitrate, and every few years for arsenic, lead, uranium and other local concerns. Your county health department can recommend a certified lab.

Radon in Hillsborough

EPA radon zone 2 — moderate potential. Predicted average indoor radon between 2 and 4 pCi/L. Test your home; many homes here exceed 4 pCi/L.

EPA Superfund National Priorities List (NPL): the country’s most serious known hazardous-waste sites, each with an EPA cleanup record (linked). Distance is measured from the ZIP center to the site’s reference point; being near a site does not by itself mean exposure — EPA site pages describe what was found and how it is being cleaned up.

What this is — and isn’t. These are records your water utility and state reported to the EPA, and the EPA’s radon map for your county. They describe the system and the area, not the water from your own tap or the air in your home. For that, read your utility’s annual Consumer Confidence Report and test: lead and radon tests are inexpensive.
