Quick Answer: Well water testing is essential before buying a Pocono home on a private well because Pennsylvania does not regulate or routinely test private wells. A standard test panel checks for coliform bacteria, E. coli, nitrates, lead, arsenic, and other contaminants common in this region. The water can look perfectly clear and still be unsafe to drink.

If you're buying a home outside a public water service area in Pike, Wayne, Lackawanna, Monroe, Orange, Sullivan, or Sussex counties, the water in the tap comes from a private well on the property. Nobody is testing that well for you. The state doesn't require it. The seller usually doesn't bother. That responsibility falls on the buyer.

Why Pocono Wells Need Testing

Pennsylvania has roughly one million private wells, more than almost any other state. The Department of Environmental Protection does not regulate water quality for private wells. There is no required testing, no required treatment, and no agency monitoring whether your water is safe.

That means contaminated wells are not unusual. Common problems in the Poconos include:

Coliform bacteria from surface contamination, septic cross-flow, or a damaged well cap
Naturally occurring arsenic in certain bedrock formations
Radon in water (separate from indoor air radon and just as serious)
Lead from old plumbing or well components
Nitrates from agriculture or septic leaching
Iron, manganese, and hardness that affect taste and plumbing but not health directly
Low pH (acidic water) that corrodes copper plumbing

A clean well today doesn't guarantee a clean well next year. Conditions change, but the baseline matters when you're buying.

What a Proper Well Water Test Covers

A real estate well water test should cover the basics at minimum:

Total Coliform and E. coli

Coliform bacteria are an indicator group. Their presence means something has gotten into the well that shouldn't be there. E. coli specifically indicates fecal contamination. Either result means action is required.

Nitrates and Nitrites

Levels above 10 mg/L for nitrates are unsafe, especially for infants. Common in agricultural areas and near old septic systems.

Heavy Metals

Lead, arsenic, copper, and iron. Arsenic is the one to watch in the Poconos. It occurs naturally in some bedrock formations and has no taste, color, or odor at dangerous levels.

pH and Hardness

Acidic water (pH below 6.5) damages copper pipes and water heaters. Hard water is a comfort issue, not a health one, but it tells you what plumbing problems to expect.

Radon in Water

Worth testing if airborne radon in the home is elevated. Water can be a major source of indoor air radon when wells draw from radon-rich bedrock.

Optional: VOCs, Pesticides, Bacteria Beyond Coliform

For homes near commercial operations, gas stations, or farms, expanded testing may be appropriate.

At Ease Home Inspection Services partners with a certified laboratory for sample collection and analysis. Standard panels can be tailored to the lender's requirements (FHA, VA, and USDA loans all have specific well water test requirements).

What the Results Mean

Lab reports come back as actual numbers compared to EPA or state action levels. A few common scenarios:

Coliform positive, E. coli negative: The well has been compromised by surface water or a damaged cap. Usually fixable with disinfection and resealing.

E. coli positive: Immediate health risk. The well should not be used for drinking or cooking until treated and retested.

Arsenic above 10 ppb: A point-of-use or whole-house treatment system is required. Installed cost can run into the thousands, depending on the technology.

Nitrates above 10 mg/L: Identify the source if possible, then treat with reverse osmosis at the kitchen tap or ion exchange whole-house.

Low pH: A calcite or soda ash neutralizer treats the whole house, and installation is a moderate expense.

A good lab report includes treatment recommendations alongside the numbers.

What to Do With Bad Results

You have bargaining power. The seller can be asked to:

Disinfect and retest the well at their expense
Install a treatment system as a condition of closing
Reduce the purchase price by the cost of treatment

Most sellers will work with reasonable requests, especially if the issue is fixable. Walking away is also a valid choice if the well is failing or contamination is severe.

After You Move In

Even with a clean test at closing, plan to test your well annually. Conditions change. A neighbor's failed septic, a heavy rain event, or a slow shift in groundwater can change results. Annual coliform tests are cheap and easy.

Frequently Asked Questions

How much does a well water test cost?

Cost depends on the panel: a basic real estate panel (coliform, nitrates, lead, arsenic, pH) costs less than an expanded panel with VOCs and pesticides. Contact At Ease Home Inspection Services for a quote.

How long do results take?

Most basic results come back in three to five business days. Coliform requires a 24-hour incubation. Plan ahead if you have a tight closing.

Can I test the water myself?

You can collect the sample yourself, but the sample needs to go to a certified lab in proper sterile containers within a strict time window. Most buyers have the inspector handle collection and chain of custody to keep the results legally defensible.

What if the well also serves an attached apartment or rental unit?

You may have additional Pennsylvania DEP requirements. Ask your inspector or attorney.
