As a service to our customers, we offer the highly respected Watercheck™ and Citycheck™ comprehensive water tests from National Test Laboratories, LTD.

National Test Labs water reports have become the gold standard in home water testing because of the laboratory's prompt, reliable service, the reasonable cost, and the clear, easy-to-understand reporting format of the tests themselves.

Test results are color-coded for easy interpretation and all aspects of the test are clearly explained in English (not the usual technical gibberish of water test reports).

A high quality water test is worth many times its cost.

Whether you have a private water source or get water from a city supplier, a top quality independent water test will give you extremely valuable information about your water.

If you find out that you have great water with no significant treatment issues, that is the most valuable information of all, and the test pays for itself many times over, both in peace of mind and in avoidance of purchasing unneeded equipment.

If you learn that you have an unsafe level of a health-threatening substance (like lead, arsenic, E.coli, chromium, or fluoride) that needs immediate treatment, the test pays for itself many times over.

If you are planning to treat a known water issue, like hardness, iron, or an unpleasant odor, a reliable, easy-to-understand independent test will give you precise information about the issue in question and provide a full picture of your water so you can select the most appropriate and cost-effective treatment. The test, again, pays for itself many times over.

When you consider the total cost of providing water for a home, a good water test is a minor expense, and the information you receive always pays for the test.

National Test Laboratories tests are not home test kits. Testing is done by certified laboratory scientists using the best testing equipment available. Your participation consists of collecting the samples according to instructions and overnighting them to National Test Laboratories.

Here’s how it works.

You order the test from us and we ship you the kit at our expense via UPS ground. You read the instructions, take the samples according to instructions, and mail them overnight (at your expense) to the test laboratory in the shipping container provided. Within a few days you will receive a detailed test report. (Sample Report - PDF) We at Pure Water Products also receive a copy of your report, so if you you would like us to help with interpretation or determining whether or not treatment is needed, we have a copy of your report. (We promise that you don't become an advertising target by buying the test. We won't even contact you unless you ask us for help.)

The kit that you receive from us includes clear, detailed instructions, a freezer pack to assure that a fresh sample arrives at the laboratory--everything you need to collect the samples and the shipping container and paperwork for sending your samples to the lab.

Watercheck™ Test Kit from National Test Laboratories, LTD.


  • Comprehensive test for well & municipal water sources
  • 83 Tested Elements
  • Coliform & E.coli Bacteria included

The Watercheck™ test is National Test Lab's most popular test offering. The Watercheck includes all of the main water treatment issues that apply both to wells and city water. It looks at 83 separate water issues, including bacteria (presence/absence for coliform and E.coli), nineteen heavy metals and minerals, six other inorganic chemicals, five physical characteristics, four trihalomethanes and forty-seven volatile organic chemicals.

Watercheck not only includes the most prevalent chemical contaminants of wells and city water supplies, but it also furnishes all the standard tests needed for treatment of common problems: pH, TDS (total dissolved solids), alkalinity, turbidity, hardness, iron, manganese. The Watercheck package also includes a test for coliform bacteria, and, if coliform is found, a test for E.coli. There are also tests for arsenic, fluoride, lead, chromium and other poisons. (See Sample report for a complete list of contaminants and water characteristics that are tested. Note that MTBE, the gasoline additive that's been in the news, is included, as is chromium, also a contaminant that has received much public attention in recent years.)

We also offer an upgrade test called Watercheck™ with Pesticides that adds tests for an additional twenty pesticides, herbicides and PCB’s. This is a valuable option that you should consider if your water comes from a lake or pond or from a well in an agricultural region.

In our opinion, the two comprehensive Watercheck products below are the best choice for most situations, both for municipal private water supplies. However, there are more testing options listed below.

The price below is the full charge to you for the testing. We pay National Testing Laboratories' fees as well as shipping of the test kit from us to you.

Your only additional expense will be overnight shipping to the NTL test location.
