DWS City Water Test


***Rated #1 Lab Water Test Kit by ""***

If you are concerned about whether Lead is in your drinking water—we have you covered!

The DWS Water Test tests for those contaminants most often cited as being related to health-related issues. In addition to testing for pathogenic bacteria, the DWS Water Test also includes testing for essential elements, heavy metals, inorganic chemicals, volatile organic compounds, PCBs and pesticides—contaminants such as nitrates, lead, mercury, MTBE, arsenic, benzene, THMs, DDT, and many more.

We test for at least 200 targeted contaminants


...If the volatile organic testing performed on our mass spectrometer identifies the spectra of what are called ‘non-targeted’ compounds, we then conduct a search for the next 50 un-targeted compounds if they are present. We do this by matching the non-targeted spectra against a database of about 250,000 compounds published by the National Institute of Standards and Technology (NIST)1.

That means our DWS Water Test evaluates your drinking water for 200 targeted contaminants PLUS a library search, if warranted, for up to 50 additional non-targeted contaminants...

All from one cost-effective water test.

The main difference between our mail-order testing service and State or County certified testing is that the latter requires laboratory-qualified personnel physically collect the sample from the source being tested. That's it!

If you need a certified lab to perform your testing either because it is required for the sale of a house or because it is for other legal reasons, you need to have your water tested by a lab that is certified in your state or jurisdiction. Drinking Water Specialists ONLY performs Informational testing (read more here).

Bacteria Water Test

  • We ship you everything you need to have us test your water for all of the other parameters:
    • water vials for you fill,
    • complete instructions,
    • information form for you to fill out,
    • return packaging, and
    • a pre-paid USPS shipping label, if you ship from within the continental U.S.
  • Once your water test kit arrives at our lab, we will normally email your water test results in about 10 business days.
  • We also send you an information sheet that tells you what you need to do if certain parameters we have tested are at higher levels than they should be.
  • If you still have questions after receiving your report, we are here to help you.

This test is only $209 including shipping both ways*credit cards accepted

 *shipping only included for the continental U.S.; if outside the continental U.S. please inquire about an additional cost.

1  If the volatile organic testing performed on our mass spectrometer identifies the presence of ‘non-targeted’ compounds, we then search for these compounds. We do this by matching the non-targeted compounds against a database of over 250,000 compounds published by the National Institute of Standards and Technology (NIST).

Think of this as a ‘facial recognition’ search where the shape of un-targeted compounds found by the mass spectrometer are compared to those in the library.

That means our DWS City Water Test evaluates your drinking water for at least 200 targeted contaminants PLUS a library search, if warranted, for additional non-targeted contaminants.

To be perfectly honest, we very rarely find any non-targeted compounds that warrant a search. That’s why we DO NOT add any of these ‘ghost’ parameters to our total parameter count. 

NOTE: If you decide you do not want to have your water tested and wish to return the test kit, unopened, within the first 30 days of ordering the test kit, we will refund your purchase price, less a 10% restocking fee.
