PFAS & Water Quality in Dover, DE

Where Dover's drinking water comes from

Central Delaware, Dover included, tends to lean heavily on groundwater drawn from the Atlantic Coastal Plain aquifers that underlie much of the region, rather than on surface-water reservoirs. Supplies across this part of the state largely rely on wells tapping those layered sands and gravels. The specific aquifer and well field serving a given street can differ, so treat this as the regional source story rather than a fact about your individual tap.

To pin down who serves your Dover address, begin with the system listed above and track down its public contact information and its annual Consumer Confidence Report, which every utility publishes. Because two homes not far apart can be on separate public water systems, the city-wide view here may not match what comes out of your tap. Calling the utility listed above is free and beats guessing. This is exactly the kind of address-level check worth reviewing when evaluating an address.

Dover water hardness

Groundwater-fed supplies across much of the region tend to carry more dissolved minerals, so harder water is a reasonable regional expectation, though your own well field may not follow the pattern. We don't state a hardness number for Dover because no such dataset exists to support it. If your shower head keeps crusting over, a cheap test strip or the hardness line in your utility's yearly report will settle the matter without any guesswork.

Reading this when you're evaluating a Dover address

City-level numbers describe the broad pattern around Dover; two homes a mile apart can sit on different water systems with very different profiles. The address report fills that gap — it identifies the public water system serving a specific property, lists any PFAS detections on that exact system, and maps the nearby industrial and Superfund sources.
