Olympian Well Water Testing

Private Well Water Safety

Private well water safety is your responsibility. Unlike city water, private wells aren’t monitored or regulated which means contaminants can go undetected. Regular certified testing is the only way to ensure your water is clean, safe, and healthy for your family.

If your home relies on a private well, water safety starts with you. Without routine government testing, hidden contaminants can affect your water at any time. Professional testing ensures your water stays safe, clean, and protected.

Why Test Your Private Well

Private wells have no utility monitoring - contamination is invisible without laboratory analysis

Municipal water users receive an annual Consumer Confidence Report summarizing system-wide test results. Private well owners have no equivalent. Your well water could change significantly due to a nearby septic failure, agricultural activity, or changes in groundwater flow - with no indication until someone tests it.

The EPA recommends annual bacteria and nitrate testing for all private wells, with comprehensive panels every 3-5 years or following any event that could affect well integrity: flooding, nearby construction, plumbing work, or changes in adjacent land use.

“I have seen arsenic exceeding the MCL in wells that appeared perfectly clear, odorless, and normal in every way. Laboratory testing is the only method of detection.”

Recommended Testing Schedule

Testing frequency by parameter

Bacteria & E. coli Annual
Nitrates Annual
Iron & Manganese Every 2-3 years
Lead & Arsenic Every 3 years
VOCs At purchase, then every 5 years
PFAS At purchase or if near impact zone
Full PWTA Panel At every NJ real estate closing

Why Annual Testing Matters

Annual well water testing is essential because water quality can change at any time, even in wells that have always produced clean water. Many contaminants have no color, odor, or taste, which means homeowners often have no idea something is wrong until someone becomes sick or a serious plumbing issue occurs. Yearly testing allows property owners to catch contamination early, before it becomes a bigger health or system problem. Seasonal weather changes, heavy rainfall, drought, and local environmental factors can all influence groundwater conditions from year to year. For example, rainfall can introduce bacteria into a well, while drought can increase mineral concentrations. Nearby construction, roadwork, agricultural activity, septic system leaks, and industrial runoff may also introduce contaminants without any visible signs. Testing once a year helps confirm whether the system is functioning properly and ensures the water continues to meet recommended safety standards. In addition to bacteria and common minerals, annual testing can help detect more serious contaminants such as arsenic, nitrates, PFAS, and volatile organic compounds. These contaminants can have significant long-term health consequences if left unnoticed. Annual testing also helps protect your plumbing system. High iron or manganese levels can stain fixtures, damage appliances, and reduce water pressure. Corrosive water can damage pipes and cause costly repairs. By testing annually, homeowners gain reliable data, track changes over time, and make informed decisions about treatment or maintenance. Most importantly, yearly testing provides peace of mind, ensuring that the water your family uses every day is safe and healthy. Regular testing is not optional, it is essential preventative care for your well and home.

Complete well water analysis for homeowners and transactions

01

Bacteria & Potability

Total coliform and E. coli - the minimum safety baseline for any potable well. Results in 24-48 hours. Required for PWTA and recommended annually for all private well owners, regardless of other testing.

Microbial
02

PWTA Full Compliance Panel

All NJ PWTA-required parameters: bacteria, nitrates, VOCs, arsenic, lead, iron, manganese, pH, turbidity, sodium, and gross alpha. Official compliance report formatted for NJ real estate closings.

PWTA
03

Comprehensive Well Panel

Full PWTA parameters plus PFAS, pesticides, herbicides, radon, radionuclides, and additional heavy metals. Recommended for first-time well testing or properties with agricultural or industrial history nearby.

Full Panel
04

PFAS & Emerging Contaminants

PFAS panel using EPA 537.1 for well owners in PFAS-impact zones or near military installations. NJ has some of the highest PFAS groundwater detections in the nation. Not in the standard PWTA panel.

PFAS
Common Contaminants

Most frequently detected contaminants in NJ and CT private wells

Bacteria

Coliform and E. coli are the most frequently detected PWTA failures. Sources: septic proximity, surface water intrusion, well head integrity failures. Never assume a well is bacteria-free without annual laboratory confirmation.

Annual testing minimum

Arsenic

Naturally occurring inorganic arsenic exceeds 10 ppb in portions of Morris, Hunterdon, Sussex, and Passaic counties in NJ, and portions of Connecticut. No taste or smell - undetectable without laboratory analysis. Carcinogenic at chronic low-level exposure.

NJ geology hotspots

PFAS & VOCs

PFAS from industrial sources and military installations has contaminated NJ groundwater in multiple counties. VOCs from solvents, dry cleaning chemicals, and underground tanks are also detected. Neither is in the standard PWTA panel - both require separate testing.

Not in standard PWTA
Property Types

Private well testing for every property type and transaction

Single-Family Homes

Owner-occupied well-water homes benefit from annual bacteria testing and periodic comprehensive panels to verify aquifer quality and well integrity.

Pre-Purchase Testing

Buyers should test beyond the PWTA minimum. PFAS, VOCs, and agricultural chemicals are not in the standard panel but are frequently detected in NJ and CT groundwater.

Agricultural Properties

Properties with agricultural history face elevated nitrate, pesticide, and bacteria risk from surface runoff contamination reaching the water table near the well head.

Post-Treatment Verification

Following water treatment system installation or well rehabilitation, certified sampling confirms target concentrations are achieved before returning the well to potable use.

Certified Sampling vs DIY Kits

When it comes to checking the safety of private well water, many homeowners consider using inexpensive DIY test kits. While these kits may seem convenient, they often lack the precision, reliability, and certified accuracy required to detect serious health-related contaminants. DIY kits typically test for only a limited range of contaminants, and the results can vary widely depending on the user’s technique, sampling environment, and the quality of the kit itself. In contrast, certified sampling performed by trained professionals ensures that the water is collected according to strict standards, handled properly during transportation, and analyzed by accredited laboratories using advanced technology. Certified sampling eliminates the risk of contamination during collection, a common issue with DIY kits, and follows chain-of-custody procedures that guarantee the sample’s integrity from start to finish. Accredited laboratory testing detects a much broader range of contaminants, including bacteria, metals, minerals, volatile organic compounds, nitrates, and emerging contaminants like PFAS. Our labs use scientifically validated methods that meet state and federal guidelines. Homeowners receive detailed reports with clear explanations, action levels, and often, recommendations for next steps. In addition to accuracy, certified testing is legally and professionally recognized, making it ideal for real estate transactions, mortgage approvals, compliance situations, and rental properties. DIY kits rarely meet these standards. Another advantage of certified sampling is expert interpretation. Professionals can explain results, identify trends, and recommend next steps. When it comes to your family’s health and the safety of your drinking water, relying on certified testing provides the clarity and confidence homeowners need. DIY kits may be tempting, but they cannot replace the precision and reliability of professional, certified sampling.
