Pennsylvania private wells
Well water treatment in Pennsylvania, built around your test result
More than 1 million Pennsylvania homes draw water from a private well, and the state sets no construction or water quality standards for any of them. When your lab report comes back, no agency calls you with next steps. Keystone Well Water exists for that moment: we explain what the numbers mean, then connect you with an independent licensed water treatment contractor working in your county. Free for homeowners.
Start from what your report found
- Total coliform or E. coli the most common failure in PA wells
- Iron, manganese, or staining the everyday problem, worst up north and west
- Nitrate above 10 mg/L watch the agricultural southeast
- Radon in water widespread and almost nobody tests for it
- Lead, arsenic, or PFAS the health-standard group, region-specific
Nobody is checking your well. That is the whole problem.
Pennsylvania is one of only a few states with no statewide private well construction standards; only local ordinances apply, and most counties have none. The state's PFAS drinking water limits stop at the public water meter too, so a private well sits outside every one of those protections. Testing, interpreting, and treating are entirely the owner's job.
That is why this site leads with education instead of sales copy. Test first, treat second: it is the order Penn State Extension and the Pennsylvania DEP both teach, and it is the order that keeps you from buying equipment your water does not need.

What the contractor you are matched with can address
Every match goes to an independent licensed professional who sizes equipment to your lab numbers, your household, and your plumbing. The two most requested starting points in Pennsylvania:
Bacteria and UV disinfection
Coliform shows up in one of every three tested Pennsylvania wells, usually because a well built to no standard lets surface water in. A correctly sized UV system fixes the symptom for good; shock chlorination alone treats it for a few weeks. This is the state's flagship well problem and the first page to read after a failed bacteria test.
UV disinfection, explainedWhole-house well water treatment
Most Pennsylvania lab reports flag more than one thing: hardness plus iron, bacteria plus nitrate. A whole-house system treats the combination in the right order at the point the water enters your home, which usually beats stacking single-purpose fixes one emergency at a time.
How whole-house systems are put togetherIron and manganese staining, softening for limestone-valley hardness, nitrate, radon in water, and PFAS each have their own page under Services in the menu, with the same rule on every one: each technology is described by what it is designed to reduce, cited to EPA or NSF standards, never as a cure-all.

Frequently Asked Questions
Is Keystone Well Water free to use?
Yes. Homeowners never pay us anything. We are paid a referral fee by the water treatment professional we match you with, and that fee never increases the price you pay for your project. The full explanation lives on our How We Make Money page, linked in the footer.
Who installs the treatment system?
An independent licensed local contractor. Keystone Well Water is a matching service, so every system is sized, installed, and serviced by the independent water treatment professional you are matched with, not by us. You can verify any Pennsylvania home improvement contractor through the Attorney General registration search before you sign.
Do I need a water test before requesting a match?
No, but it helps. A recent lab report lets the contractor you are matched with quote the right technology instead of guessing. If you have not tested yet, request the match anyway and say so; testing through a DEP-accredited lab or the Penn State Agricultural Analytical Services Lab is the usual first step.
What parts of Pennsylvania do you cover?
The whole state, with the deepest coverage in the Lancaster, York, and Berks corridor and the surrounding south-central and southeastern counties. Statewide requests are welcome; match times can be longer outside the corridor.
