Test Your Well | Certified Well Water Testing Lab Directory

Water testing prices vary widely depending on what you're testing for and which lab you use. Here's a realistic breakdown of what to expect — and where to find affordable certified testing.

Quick Summary

| Test Type | Typical Cost | |---|---| | Basic coliform bacteria + nitrates | $40–$100 | | Standard panel (10–20 parameters) | $100–$200 | | Comprehensive panel (50+ parameters) | $200–$400 | | PFAS testing (6 EPA compounds) | $75–$200 | | arsenic only | $15–$40 | | lead only | $20–$50 | | Full VOCs panel | $100–$200 | | radon | $25–$75 |

Basic Testing: $40–$100

A basic test covering coliform bacteria and nitrates is the minimum recommended annual test for private well owners. At most certified labs, this runs $40–$100 depending on your state and lab.

Some county health departments offer subsidized testing at lower cost — worth checking before going to a private lab.

Standard Panel: $100–$200

A standard or "essential" panel typically adds:

pH, hardness, iron and manganese, manganese
Total dissolved solids (TDS)
Sulfate, chloride, sodium
Possibly arsenic and lead

This is the right starting point if you've never tested before or haven't tested in several years. For $100–$200 you get a real picture of your water.

Comprehensive Panel: $200–$400

A comprehensive panel covers 50–100+ contaminants including heavy metals, volatile organic compounds (VOCs), agricultural chemicals, and in some cases PFAS. If you have specific concerns about your area, are buying a home, or just want full peace of mind, a comprehensive panel is worth it.

Add-On Tests

PFAS: $75–$200 for the six EPA-regulated compounds. Some labs offer broader PFAS panels (40+ compounds) for more. Worth adding if you live near military bases, airports, or industrial sites.

Radon: $25–$75. Particularly relevant in New England, Appalachia, and parts of the Midwest.

pesticides/herbicides: $50–$150 as an add-on. Important in farming communities.

Mail-In Testing vs. Local Lab

Mail-in kits are typically in the $80–$300 range for comprehensive panels and include:

Sample containers shipped to you
Prepaid return shipping (in most cases)
Results by email

They're convenient and often competitively priced. The tradeoff: you're handling the sample yourself, and bacteria samples are time-sensitive (must arrive at the lab within 24–48 hours).

Local certified labs let you drop off a sample in person, which is better for time-sensitive tests. Pricing is similar to mail-in, sometimes lower for basic tests.

What Affects the Price?

Number of parameters tested — More tests = higher cost
Lab certification level — Some certifications require more rigorous methodology
Turnaround time — Rush processing costs more (typically +$25–$75)
Location — Urban labs in competitive markets may charge less than rural labs
State-specific programs — Some states subsidize testing for low-income households

How to Save Money

Bundle tests — A comprehensive panel is almost always cheaper per-contaminant than running individual tests
Check your county health department — Many offer free or discounted testing for residents
Test strategically — Run a full comprehensive panel once, then test only for what you found or what's specific to your annual risks

Is It Worth It?

A comprehensive well water test costs less than a single restaurant dinner for a family. The potential cost of not testing — treatment for a waterborne illness, remediation of a contaminated well, or health effects from long-term exposure — is orders of magnitude higher.
