Well water in Schuylkill County, Pennsylvania

1in2

Testing strongly recommended

private wells tested between 2007 and 2025 in Schuylkill County had total coliform above the EPA limit (0 MPN/100mL), according to the Penn State water testing lab.

142 private wells tested 2007 to 2025 in state summaries; 756 test results across 15 contaminants from at least 93 wells, 1931 to 2023; iron has the most at 108. Data refreshed September 16, 2026.

Compiled by Nick at Well Water Nerd from public records. How these pages are built

These are samples homeowners paid to send to the Penn State lab, often because of a suspected problem, so shares above the limit run higher than a random survey would find.

An estimated 46,004 people in Schuylkill County get their drinking water from a private well, per USGS 2015 county water use. That is about 32% of residents.

Separately, the USGS national arsenic model estimates that 2% of the 46,004 people on private wells in Schuylkill County draw water above 10 ug/L (the model's range is 1% to 3%), from geology and well depth rather than local tests.

What individual samples found

Each row summarizes every public sample for that contaminant inside Schuylkill County. Above limit means above the EPA maximum contaminant level; where EPA has no enforceable limit, the row shows a health guideline or nuisance level instead.

Over time

Share of samples above the limit by period. A cell needs ten samples to show; a comparison needs twenty in each period. Later periods sample fewer wells, and often the ones already known to have a problem.

What this means

Among homeowners in Schuylkill County who sent a sample to the state lab, the health-based limits most often exceeded were total coliform (52% of 142 wells), E. coli (16% of 142 wells), and arsenic (8% of 36 wells). These are ordinary wells tested by their owners, so the shares are the best available picture of a typical well here, with one caveat: people test more often when they suspect a problem.

Manganese and iron exceed the state's advisory level in a sizable share of wells; these are mostly a taste, staining or diet issue rather than a toxicity one.

Wells in Schuylkill County

2,568 domestic wells in Schuylkill County are on record with the state. 97% are drilled into bedrock, and the typical well is 180 feet deep (one in ten goes past 375 feet).

In a typical Schuylkill County well, bedrock starts about 31 feet down, the median yield is 15 gallons per minute, 6% of wells yield under 3 gallons per minute and usually need a storage tank.

Bedrock wells are where arsenic, uranium and radon come from: the water sits in fractures in granite and metamorphic rock and picks up whatever the rock carries. That is why testing for those three matters more here than in a dug or gravel well.

Find your own well's report

The state keeps the driller's report for most wells drilled since 1984. It tells you how deep your well is, where bedrock starts, and how much water it makes, which decides what treatment can work.

Open PaGWIS (Pennsylvania Geological Survey) and choose Water Well.
The record lists depth, depth to bedrock, yield and use; drillers have reported new wells to the state since 1966.

Pennsylvania has no private well construction standard and does not require testing, so many older wells have no record at all.

The rock under Schuylkill County

Valley and Ridge aquifers

Sandstone and carbonate-rock. Layered sandstone and limestone means a well may draw from either. Hardness and iron are routine, and the limestone layers can carry bacteria and nitrate from the surface quickly, so test for both yearly.

Classification from the USGS Principal Aquifers of the United States (national map, 2003 edition, GIS release 2015), read at the county centroid. A single well can sit in a different unit, especially near a boundary.
