Rely on a private well in Readington? A quick yearly water check can protect your health, your plumbing, and your peace of mind. Many local wells draw from shallow deposits or fractured bedrock, which means conditions can change after heavy rain, nearby landscaping, or even routine maintenance. This guide gives you a clear testing checklist, when to add extra parameters, how to handle sampling and labs, and what your results mean for daily use and a future home sale. Let’s dive in.
Why annual testing matters in Readington
Readington Township sits over a mix of shallow unconsolidated deposits and fractured bedrock aquifers. That geology, plus common septic systems and nearby agriculture, increases the likelihood of certain contaminants. Microbial issues can show up after storms or if a well cap is damaged. Nitrate and nitrite can come from septic fields and fertilizers.
Some bedrock wells in the region can have naturally occurring arsenic or radon. Iron and manganese are also common and can stain fixtures or create off tastes and colors. Plumbing can contribute lead and copper, especially in older homes. In some areas of New Jersey, PFAS have emerged as a concern. VOCs or petroleum compounds may be relevant near gas stations, spill sites, or industrial uses.
Core annual tests to order
Order these every year for any private well in Readington:
- Total coliform and E. coli
- Nitrate as nitrogen and nitrite
- pH
- Total dissolved solids (TDS) or conductivity
- Hardness
- Iron and manganese
- Visual notes by sampler (color, odor, turbidity)
These parameters help you catch fast-changing health risks like bacteria and nitrate. They also track water chemistry that affects plumbing, appliances, and the performance of treatment systems.
Add every 2–3 years
Layer in these parameters every 2 to 3 years, or sooner if you renovate plumbing or notice changes:
- Lead and copper
- Sodium and chloride
- Sulfate
- Alkalinity and calcium
These results help with corrosion control, water softener sizing, and understanding salt or sulfate levels that can affect taste, diet, and fixtures.
Site-specific add-ons to consider
Arsenic
- When to test: If your well taps bedrock, if nearby wells have reported arsenic, if you have never tested for it, when changing treatment, or if you plan to sell.
- Frequency: At least once for a baseline. If detected, retest every 1 to 3 years or after treatment changes.
- Why it matters: Arsenic can be naturally occurring in some bedrock aquifers and is a chronic health concern.
Radon in water
- When to test: If your well draws from fractured bedrock or if you have high indoor radon in air. Also consider if local geology suggests risk.
- Why it matters: Radon in water can transfer to indoor air. Water mitigation uses different methods than standard filters.
PFAS
- When to test: If you are near potential sources like airports, firefighting training areas, landfills, or certain industrial sites, or you want a baseline.
- Frequency: At least once to establish a baseline. Retest if detected or if new information emerges nearby.
- Why it matters: PFAS are persistent and may have chronic health effects.
VOCs and petroleum compounds
- When to test: If you are near a gas station, dry cleaner, industrial site, spill location, or if you notice fuel or solvent odors.
- Why it matters: Some VOCs can pose immediate and longer-term health risks and often require specialized treatment.
Pesticides and herbicides
- When to test: If you live near active agriculture, extensive turf care, or you use pesticides on your property.
- Why it matters: Certain pesticides can migrate to groundwater depending on local use and soils.
Bacteria follow-up
- When to test: If you ever get a positive total coliform or E. coli result, retest right after disinfection and any wellhead repairs.
- Why it matters: Recurring positives point to well cap, casing, or drainage issues that need a fix.
Sampling and labs in Hunterdon County
- Use a state-certified drinking water lab. New Jersey DEP maintains a list of certified laboratories and methods. Certified labs are also required for test results used in real estate transactions.
- Follow lab instructions exactly. Labs provide bottles, preservatives, and forms. For example, lead and copper often require a first-draw sample after at least 6 hours of stagnation. Bacteria bottles are sterile and must be kept cold and delivered quickly.
- Timing matters. Bacteria samples are time sensitive and usually need delivery within 24 hours. Metals may need acid preservation. Each analyte has a maximum holding time.
- Local help. The Hunterdon County Health Department can advise on drop-off points, training, or transport options. Rutgers Cooperative Extension in Hunterdon offers homeowner education and occasional workshops.
- Cost and turnaround. Basic bacteria and nitrate panels are usually modest in cost with 24 to 48 hour turnaround. Standard chemistry takes a few days. PFAS and VOC panels cost more and often take longer due to specialized methods.
Read results and take next steps
Bacteria
If total coliform is detected, inspect the wellhead, cap, and drainage. If E. coli is detected, treat it as an immediate health concern. Use bottled or boiled water for drinking until you disinfect the system, address the source, and retest with clean results.
Nitrate and nitrite
The EPA maximum contaminant level for nitrate as nitrogen is 10 mg/L. Elevated nitrate is hazardous for infants and pregnant women. If results are high, avoid using water for infant formula and consider treatment such as reverse osmosis, ion exchange, or blending with a low-nitrate source.
Arsenic
If arsenic is present, consult a water treatment professional to evaluate options like reverse osmosis, adsorptive media, or coagulation and filtration. Because arsenic is a chronic contaminant, choose point-of-use or whole-house systems based on how you use the water, and retest after installation and at routine intervals.
PFAS
If PFAS are detected, review NJ guidance and consider treatment options such as granular activated carbon or high-pressure membrane systems. PFAS vary by compound, so professional evaluation is important.
VOCs and petroleum compounds
If VOCs are present, avoid consuming the water until a professional assesses risk and mitigation. Common treatments include air stripping or activated carbon. Some cases may require an alternate supply.
Metals
Iron and manganese mostly cause aesthetic issues like staining and metallic taste. Oxidation and filtration often help. Lead and copper are health concerns linked to corrosion and plumbing materials. Consider corrosion control and, where needed, plumbing upgrades. Retest after any changes.
Radon in water
If radon is elevated in water, mitigation typically involves aeration systems or point-of-use treatment. You should also test radon in indoor air to understand the combined exposure.
Ongoing maintenance
Service softeners and filters on schedule and retest after service. Hardness, iron, and TDS inform treatment sizing and media life. Recurring bacteria indicate a need to improve wellhead sealing, casing condition, and site drainage.
Quick ordering roadmap
- Annual baseline order:
- Total coliform and E. coli, nitrate and nitrite, pH, TDS or conductivity, hardness, iron, manganese.
- Every 2–3 years or before listing for sale:
- Lead and copper, sodium, chloride, sulfate, alkalinity, calcium.
- One-time baseline or if risks apply:
- Arsenic, radon in water, PFAS, VOCs or petroleum screen, targeted pesticides or herbicides.
- Event-triggered add-ons:
- After a positive bacteria result, retest immediately after shock chlorination and fixes.
- If nearby land use changes or a known spill occurs, consider VOCs or PFAS.
Selling a home with a well
Well testing is a common part of buyer inspections in Hunterdon County. As a seller, having recent test results can speed negotiations and reduce surprises. Consider an expanded pre-listing panel, including arsenic and lead or copper, so you can address issues before the property hits the market.
Disclosure expectations and required parameters can vary by transaction type and current state or county guidance. Confirm the latest requirements with the Hunterdon County Health Department, NJDEP resources, or legal counsel. If results exceed standards, buyers and sellers often negotiate treatment, repairs, or price adjustments.
