Well Water Testing In Glenmoore: What To Check

Thinking about buying or selling a home in Glenmoore with a private well? Water quality can make or break your timeline, negotiation power, and peace of mind. You want clarity on what to test, how to sample correctly, and what happens if results come back with issues.

In this guide, you’ll learn the essential tests for Glenmoore wells, how to select a certified lab, how to read results, and what to expect for remediation and closing timelines. Let’s dive in.

Why well testing matters in Glenmoore

Private wells in Pennsylvania are not regulated like public water systems. There is no routine government testing for most private wells, so you are responsible for testing and treatment. The Chester County Health Department can provide guidance, local resources, and information on testing kits and certified labs.

Glenmoore’s mix of residential septic systems and nearby agricultural land raises common risks for bacteria and nitrates. Older plumbing can contribute lead or copper. Localized spills or industrial sites may pose volatile organic compound (VOC) risks. Natural geology can add trace metals such as arsenic in certain areas. That is why a smart testing plan starts with core health risks and expands based on what your site and results suggest.

What to test first

Start with a baseline panel that covers the most common and important health indicators.

• Bacteria (Total Coliform and E. coli). Any E. coli is an immediate health concern and requires corrective action and retesting. Total coliform without E. coli still deserves follow-up.
• Nitrate (as nitrogen). Nitrate can come from septic systems and fertilizers. The EPA benchmark is 10 mg/L as nitrogen. Levels at or above this require treatment, not just disinfection.
• pH and Total Dissolved Solids (TDS). These guide corrosion risk, taste, and treatment choices. EPA’s secondary guidelines suggest pH 6.5 to 8.5 and TDS near 500 mg/L as reference ranges.

When to add more tests

Add targeted tests when triggers apply to your property, plumbing, or location.

• Lead and copper. Test if plumbing may predate 1986 or you see corrosion signs. Any detectable lead is a concern in a private well; aim for as close to zero as possible.
• Arsenic. Consider testing if local geology or prior results suggest risk. The EPA benchmark is 10 µg/L.
• VOCs and gasoline-related compounds. Test if near gas stations, underground storage tanks, industrial or dry-cleaner sites, or areas with heavy pesticide use.
• Pesticides and herbicides. Consider if adjacent to agricultural fields or intensive lawn care.
• Radon in water. Test if indoor air radon in the house is high, since well water can contribute to indoor levels.
• Other minerals (iron, manganese, hardness, sulfate). Add if you notice staining, taste issues, or scale buildup.

How to choose a lab and sample right

Your results are only as good as your sampling and lab.

• Use a Pennsylvania state‑certified drinking-water laboratory. Ask the lab if they are certified for the analytes you need and for residential drinking water. The Chester County Health Department and Pennsylvania DEP maintain resources to help you find certified labs.
• Use the lab’s bottles and instructions. Bacteria samples require sterile vials from the lab. Some tests (metals, VOCs) need preservatives or special bottles.
• Follow proper bacteria sampling steps. Remove the aerator, disinfect the tap as instructed, run cold water to flush lines for 1 to 2 minutes, then fill the sterile bottle without touching the rim. Label, refrigerate if required, and deliver to the lab quickly. Many bacteria samples must be received within 24 hours.
• Confirm holding times. Different analytes have different timelines and preservation needs. Ask the lab how fast to deliver and whether cooling is required.
• Use chain-of-custody paperwork. For real estate, make sure your sample is documented properly. Ask about split samples if needed.
• Know typical costs. Prices vary by lab, but as a general guide: bacteria 20 to 60 dollars, nitrate 15 to 50 dollars, metals 20 to 100 dollars each or a panel 100 to 300 dollars or more, VOC panel 100 to 400 dollars.
• Local kits and help. The Chester County Health Department can point you to local testing resources, sample kits, and certified labs.

How to read results and decide next steps

Use public water standards as conservative benchmarks for private wells.

• Any E. coli is urgent. Treat, correct the sanitary issue, and retest.
• Total coliform without E. coli still requires follow-up and corrective steps.
• Nitrate at or above 10 mg/L as nitrogen requires treatment. Disinfection alone does not remove nitrates.
• Lead and arsenic are best kept at or below EPA benchmarks, with the goal of as close to zero as practical for lead.
• Even below-benchmark levels can be a concern for infants, pregnant people, or those with health conditions.

Remediation options and timing

If results show an issue, you can often correct it and move forward with a documented plan.

• Shock chlorination for bacteria. Disinfect the well and plumbing per guidance, allow contact time, flush, then retest in 7 to 14 days. Chlorination does not remove nitrates, VOCs, or many metals.
• Nitrate treatment. Options include reverse osmosis at the tap, ion exchange, or blending with a low-nitrate source. Installation often takes 1 to 4 weeks or more, followed by performance testing.
• Arsenic treatment. Consider specialized media or reverse osmosis. Installation and commissioning typically take 1 to 4 weeks.
• Lead and copper. Replace fixtures, remove lead sources, or install point-of-use filters certified for lead reduction. Work can often be completed in days to weeks.
• VOCs. Whole-house granular activated carbon or air stripping may be appropriate. These systems often take 2 to 6 weeks or more from vendor selection to installation.

After any remediation, plan to retest. Bacteria should be retested 7 to 14 days after disinfection and again after any plumbing repair. Chemical contaminants should be retested after system startup and on a schedule recommended by your contractor and lab.

Plan for closing with confidence

Build well testing into your timeline early so you have room to respond.

• Order baseline tests as soon as the inspection contingency starts.
• If bacteria are positive, disinfect and retest in 7 to 14 days.
• If chemical contaminants exceed benchmarks, allow several weeks for system selection, installation, and verification.
• Document everything. Keep lab reports, contractor proposals, installation records, and performance tests. Buyers should request proof that any treatment system is installed correctly and working.

Sample transaction timeline

• Day 0 to 3: Order and collect bacteria, nitrate, pH, and TDS.
• Day 1 to 4: Receive initial lab results, depending on the lab.
• If bacteria are positive: Day 4 to 10 for shock chlorination and fixes, then Day 11 to 24 for retesting.
• If nitrate or chemicals exceed benchmarks: Day 0 to 30+ for system design, installation, and verification testing.

Buyer and seller checklist

• Order baseline tests: bacteria (total coliform and E. coli), nitrate as nitrogen, pH, TDS.
• Add lead and copper if plumbing is older or water is corrosive.
• Add arsenic if geology or prior tests suggest risk.
• Add VOCs and pesticides near gas stations, industrial sites, or agricultural fields.
• Add iron, manganese, hardness if you see staining, taste, or scale.
• Use a Pennsylvania state‑certified drinking-water lab and follow chain-of-custody.
• Confirm holding times and use the lab’s bottles and instructions.
• Start testing early in your contingency period to protect your timeline.
• Retest after any disinfection or treatment installation.
• Keep all reports and system documents for the next owner.
