This page is a complete guide to testing your drinking water and choosing the right water test kit, for both private well water and city (municipal) water. It is a home water test kit and lab water test hub covering the well water test kit, the city water test, the drinking water test kit, and the tap water test kit, plus a full water quality test panel. It explains how to test your water quality and run a water quality test with a certified mail-in laboratory test, why a certified lab test is more accurate than DIY test strips or your city's annual Consumer Confidence Report, and what each test is for. Tests available: the Well Water Test (53 contaminants including total coliform and E. coli bacteria, $199), the City Water Test (47 contaminants, $199), the Advanced Well (113 contaminants, $329) and Advanced City (109 contaminants, $279) panels with full VOC and pesticide scans, and focused single-contaminant tests for iron ($89), iron speciation, water hardness in grains per gallon ($99), hydrogen sulfide / rotten-egg smell ($139), coliform and E. coli bacteria ($139), nitrate ($139), lead and copper ($89), tannins ($99), uranium ($89), arsenic speciation ($519), a 60-compound VOC scan ($169), radon ($129), fluoride ($99), hexavalent chromium / chromium-6 ($169), a 140-compound herbicide and pesticide screen ($269), and PFAS forever chemicals ($349). Every test is analyzed by an independent, NELAC/ELAP-accredited laboratory in a network of 200+ certified labs, measuring contaminants down to parts per billion using EPA methods (ICP-MS, ion chromatography). Results compare against EPA Maximum Contaminant Levels: lead action level 15 ppb, nitrate 10 mg/L, arsenic 10 ppb, uranium 30 ug/L, iron aesthetic 0.3 mg/L. Symptom-to-test guide: orange or rust stains mean test for iron; rotten-egg smell means test hydrogen sulfide; white scale and spots mean test hardness; yellow or tea-colored water means test tannins; blue-green stains mean test lead and copper; a new or untested well means run the full panel with bacteria; wells near farmland mean test nitrate and pesticides. How it works: order the kit (free shipping), collect a sample in about 5 minutes, mail it back with the prepaid label, and get certified results in about 5 business days. What makes Mid Atlantic Water different: co-owner Aidan, a water treatment specialist with 32 years of experience, personally reviews every result and tells you exactly what needs treatment, what does not, and which system and size to install, or that your water is clean and you need nothing. Mid Atlantic Water has specialized in well and city water treatment since 1997 and ships nationwide to all 50 states.

Best Well Water Test Kit (2026): 53 Contaminants, Certified Lab
Watch the complete guide

Every other water test hands you a report and walks away. We read your results and tell you what to do. Aidan personally reviews every certified lab report, tells you which contaminants need treatment and which are fine, and recommends the exact system, size, and order, or tells you honestly that your water is clean and you need nothing at all. Mid Atlantic Water has specialized in well and city water since 1997.

Complete Water Test Panels (Start Here)

If you are on a new or untested source, or you want the full picture, start with a complete panel. These are our most popular home water test kits: the Well Water Test covers 53 contaminants including bacteria; the City Water Test is the drinking water test kit for municipal homes, covering 47 (no bacteria, since city water is disinfected); and the Advanced panels go deeper (109 to 113 parameters) with a full VOC and pesticide scan. Every panel is a full water quality test run at an independent, NELAC/ELAP-accredited lab and reviewed personally by Aidan.

Single-Problem Tests (Know the Symptom, Target It)

Already know your main issue? Target it directly with a focused, lower-cost test. Iron for orange-brown stains, hardness for scale, hydrogen sulfide for rotten-egg smell, coliform and E. coli for safety, nitrate for agricultural wells, lead and copper for plumbing, fluoride, and tannins for yellow water. Each one returns the exact number you need to size the matching treatment system, and Aidan tells you what to do with it.

Specialty & Advanced Contaminant Tests

For specific health concerns and high-anxiety contaminants: arsenic speciation, uranium, radon, hexavalent chromium (chromium-6), a 60-compound VOC scan, a 140-compound herbicide and pesticide screen, and PFAS forever chemicals. These use specialized lab methods and sampling. If your geology, location, or news has you concerned about one of these, this is how you find out for certain.

Water Testing Comparison

Certified lab test vs DIY strips, the utility report, and doing it yourself

There are four common ways people check their water, and they are not equal. What separates the MAW approach: the same independent, third-party certified lab the best mail-in services use, PLUS a personal review of your results by Aidan, a water treatment specialist with over 30 years of experience, who tells you exactly what needs treatment, what does not, and which system and size to install. DIY strips cannot detect lead or arsenic at health-relevant levels, and your city's annual report describes water at the treatment plant, not at your tap.

Both mail-in certified lab services and Mid Atlantic Water use the same independent NELAC/ELAP-accredited laboratory network, so the raw lab data quality is identical. The difference is interpretation and follow-through: we read your specific numbers and tell you what to do, and we stand behind the equipment if you need it. Strip tests and the utility Consumer Confidence Report have their place, but neither tells you what is actually coming out of your kitchen faucet at a health-relevant level of detail.

Step 1: Spot the Symptom

Match your water symptoms to the right test

Start with what you can see, taste, or smell. Each symptom points to a specific test that gives you the number you need to fix it. But remember: many of the most serious contaminants (bacteria, lead, nitrate, arsenic) have no symptoms at all, which is why a full panel is the safe starting point for any untested well.

Orange rust staining in a sink from iron in well water

Orange, brown, or rusty staining on sinks and laundry

Reddish-orange staining and a metallic taste point to iron. Test it to get the exact level (mg/L) that sizes an iron filter.

Iron Water Test Test for iron
A homeowner noticing a rotten-egg smell from a faucet

Rotten-egg or sulfur smell, worse on hot water

That sewer or rotten-egg odor is almost always hydrogen sulfide gas. Test sulfide and pH to size a sulfur filter correctly.

Hydrogen Sulfide Test Test for H2S
White limescale buildup on a showerhead from hard water

White scale, spots on dishes, soap won't lather

Classic hard water. Test your hardness in grains per gallon, the one number that sizes a water softener.

Hardness Test Test hardness (gpg)
Yellow tea-colored well water in a glass

Yellow or tea-colored water

Yellow, amber, or tea-colored water with an earthy note usually means tannins, but iron can also discolor water. Test tannins to tell them apart.

Tannins Test Test for tannins
Blue-green copper staining on a white sink from acidic water

Blue-green stains on fixtures (and old plumbing)

Blue-green staining signals copper leaching from plumbing, often driven by acidic water; lead can leach the same way. Test lead and copper at the tap.

Lead & Copper Test Test lead & copper
A laboratory petri dish showing bacteria colonies grown from an untested well water sample

New, recently purchased, or never-tested private well

No one tests or disinfects a private well but you. Start with the full 53-contaminant Well Water Test, including bacteria, before you trust the water.

Well Water Test (53) Run the full panel
Farmland next to a rural home with a private well

Well near farmland, fertilized fields, or septic

Agricultural areas raise the odds of nitrate (dangerous for infants) and pesticide runoff, both invisible and tasteless. Test nitrate, and the pesticide screen if there is spraying nearby.

Nitrate Test Test nitrate (+ pesticides)

No symptoms, but an infant, pregnancy, or you just want certainty

Many of the most serious contaminants (bacteria, lead, nitrate, arsenic) give no taste, color, or smell. If anyone vulnerable drinks the water, test the full panel; clean results are real peace of mind.

When in doubt, start with the full panel

If you have more than one symptom, a brand-new or untested source, or you just want the complete picture, the 53-contaminant Well Water Test (or 47-contaminant City Water Test) reads everything at once, so you only sample once and Aidan can build a complete plan. From $199, ships free, expert review included.

FULL PANEL From $199 - Expert review
Step 2: Match Your Test

Find the water test that's right for you

Pick the row that matches your situation to see which test to start with. On a new or untested private well, the full 53-contaminant panel is almost always the right first step; for a single known problem, a focused test is faster and cheaper.

Still not sure? Text Aidan what you're seeing and he'll tell you exactly which test to run, free. When in doubt, the full panel reads everything in one sample.

Step 3: Read your results

How to read your water test results

Water tests aren't sized like equipment, but the report can look intimidating. Here are the key terms so you can read your own results with confidence, and remember that Aidan reviews every result with you so you never have to interpret it alone.

mg/L and ppb (the units on your report)

Most contaminants are reported in milligrams per liter (mg/L), which equals parts per million (ppm), or in micrograms per liter (ug/L), which equals parts per billion (ppb). 1 mg/L = 1,000 ug/L. Lead and arsenic matter at the ppb level, which is why strips that read in whole numbers cannot detect them safely.

MCL (Maximum Contaminant Level)

The EPA's enforceable legal limit for a contaminant in public drinking water (for example, lead action level 15 ppb, nitrate 10 mg/L, arsenic 10 ppb, uranium 30 ug/L). Your result is compared against the MCL to decide whether treatment is needed. Some contaminants have only an aesthetic (secondary) standard, like iron at 0.3 mg/L.

NELAC / ELAP certified lab

Your sample is analyzed by a laboratory accredited under the National Environmental Laboratory Accreditation Conference / Environmental Laboratory Accreditation Program, the same standard state health departments require. It means the result is legally defensible and scientifically rigorous, not an estimate.

Present / Absent (bacteria)

Bacteria results are reported as present or absent rather than a number. The EPA standard for drinking water is zero total coliform and zero E. coli, so any detection means action is needed (typically well shock-chlorination plus UV disinfection).

How it works

How certified mail-in water testing works

Mail-in certified lab testing is simple: you collect a sample at your tap, ship it in the prepaid kit to an independent NELAC/ELAP-accredited laboratory, and get back precise, EPA-method results in about 5 business days. The one thing we add that no one else does is the last step, a real water treatment expert who reads your numbers and tells you exactly what to do about them.

01

Order the kit and collect your sample

Pick the test that fits your situation and we ship it free. It comes with the right bottles and preservatives, simple instructions, and a prepaid return label. Collecting a sample at your tap takes about 5 minutes.

02

Mail it to an independent certified lab

Drop the prepaid package with a carrier. It goes to one of 200+ NELAC/ELAP-accredited laboratories in the SimpleLab network, the same independent labs state health departments use. We never touch the testing, so the data is impartial.

03

Get your certified lab report

Your results arrive by email, typically in about 5 business days for the core panels (specialty tests take longer). Every contaminant is measured precisely and compared against its EPA standard.

04

Aidan reviews it and tells you what to do

This is what makes us different from every other test. Aidan, a water treatment specialist with 30+ years of experience, reads your specific numbers and tells you what needs treatment, what does not, and exactly which system and size to install, or that your water is clean and you need nothing.

Your kit and sampling

What's in your kit, and how to collect a good sample

There's nothing to install. A home water test kit is about collecting a clean, accurate sample and getting it to the lab quickly. Every kit ships with everything you need, and the whole process takes about five minutes. Here's exactly what's included and how to do it right.

5 min

To collect your sample. Fill the provided bottles at your tap following the instructions. No tools, no plumbing, no technical knowledge.

~5 days

Lab turnaround. Core well and city panels report in about 5 business days once the lab receives your sample; specialty tests take longer.

Free

Shipping both ways. Free shipping to your door and a prepaid return label to the lab. Every home water test kit includes chain-of-custody paperwork.

What's in every kit

  • Sample bottles and vialsPre-labeled containers with any preservatives the lab method requires, so your drinking water test stays accurate in transit.
  • Step-by-step collection instructionsExactly how and where to draw the sample (which tap, hot or cold, first-draw or flushed) so the result reflects your real water.
  • Prepaid return shipping labelDrop the kit at any carrier location. It routes to the nearest certified lab in the SimpleLab network.
  • Chain-of-custody documentationPaperwork that makes your lab result defensible for real estate, mortgage, or health purposes, not just a home test strip guess.

How to collect your sample

  1. Register your kit (if your test includes a registration card) so the lab can match your sample to your results and contact info.
  2. Run the correct tap as the instructions specify. Some tests want a first-draw sample (important for lead and copper); others want the line flushed first.
  3. Fill each bottle to the marked line in the right order, cap tightly, and avoid touching the inside of the cap or bottle (this matters most for bacteria and PFAS).
  4. Seal the samples in the included bag, add the chain-of-custody form, and pack them in the box.
  5. Collect on a Monday or Tuesday and mail it the same day. Samples that sit over a weekend in transit can affect time-sensitive results like bacteria. Early-week collection keeps your data clean.
  6. Drop the prepaid package with the carrier. Collect early in the week so it reaches the lab before the weekend.

FAQ

Frequently asked questions

The most reliable way is a certified mail-in lab test: you collect a sample at your tap, ship it in a prepaid kit to an independent NELAC/ELAP-accredited laboratory, and get back precise measurements compared against EPA standards. For a private well, start with a full panel that includes bacteria, metals, nitrate, and hardness. For city water, focus on lead, copper, hardness, and disinfection byproducts. DIY strips can give a rough hint but cannot detect lead, arsenic, or nitrate at the levels that matter for health.

The best kit is a certified-lab mail-in test matched to your situation, not a strip kit. For most private wells, a full 53-contaminant panel with bacteria is the right starting point; for a single known problem like iron, hardness, or rotten-egg smell, a focused single-contaminant test is faster and cheaper. What separates our kits is that a 30-year water treatment specialist reviews your results and tells you exactly what to do, instead of leaving you with a report and no plan.

Our certified lab tests range from about $79 for a single contaminant (like iron or hardness) to $199 for the full well or city panel, up to $329 for the deepest advanced panel. DIY strips cost $15 to $40 but cannot measure health-relevant contaminants accurately. Sending a sample to a local lab yourself is possible but you handle chain-of-custody and interpretation. Every one of our tests includes free shipping and a personal expert review of the results.

Certified mail-in lab kits are highly accurate; DIY color-strip kits are not. A mail-in kit sends your water to a NELAC/ELAP-accredited lab that uses the same instruments and methods as state health departments (ICP-MS for metals, ion chromatography for anions), measuring down to parts per billion. Strip kits rely on a color change you eyeball against a chart and cannot detect lead, arsenic, or nitrate at safe-limit levels. If you want a result you can act on, use a certified lab.

At least once a year for bacteria and nitrate, and right away after flooding, well or pump work, or any change in taste, color, or smell. Private wells are not monitored by anyone but you, and conditions change with the seasons and the water table. A fuller panel (metals, hardness, and the rest) every 2 to 3 years, or whenever you notice a new problem, keeps you ahead of issues. City water customers usually test once to establish a baseline and again if they notice a change or move into an older home.

It depends on your source and symptoms. Every private well should be tested for bacteria (total coliform and E. coli), nitrate, and the core chemistry (pH, hardness, iron, manganese). Add arsenic, uranium, or radon if you are on bedrock, nitrate and pesticides near agriculture, and lead and copper in older homes. City water customers should focus on lead and copper (from home plumbing), hardness, fluoride, and disinfection byproducts. If you are unsure, a full panel covers the common contaminants in one sample.

Yes, because your utility's annual report describes water at the treatment plant, not at your tap. Lead and copper leach into water from your home's own service line, fixtures, and pipes after the water leaves the plant, and the only way to know your tap's actual levels is to test at the faucet. City water customers can skip the bacteria panel (municipal water is disinfected and monitored) and focus on lead, copper, hardness, fluoride, and disinfection byproducts.

Core panels (well, city) take about 5 business days at the lab once your sample arrives; single-contaminant tests are similar, and specialty tests (PFAS, radon, arsenic speciation, pesticides) take 8 to 15 business days. You'll get the certified lab report by email, and then Aidan reviews it and reaches out with his recommendation, usually within a day of the results posting.

A strip gives you a rough color-matched guess on a few parameters; a certified lab test gives you exact, defensible numbers on dozens of contaminants. Strips cannot detect lead, arsenic, or nitrate at health-relevant levels and are easy to misread. A lab test uses mass spectrometry and ion chromatography to measure down to parts per billion, the same methods regulators use. For sizing treatment equipment or making a health decision, only the lab number is reliable.

Match each contaminant that exceeds its EPA standard to the right treatment, in the correct order, then size each system to your numbers and household. That is exactly what Aidan does for you: he reads your report, tells you what needs treatment and what is fine, and recommends the specific systems, sizes, and installation order (for example sediment, then iron filter, then acid neutralizer, then softener, then UV). If your water is clean, he tells you that too. Testing first is what lets you buy the right equipment once instead of guessing.
