This is a professional, full spectrum water test kit (minus pesticides). Our test covers dozens of contaminants, including heavy metals, Chlorination byproducts, and Coliform bacteria. The water is analyzed by one of the most respected labs in the country. All you need to do is fill the sample bottles in the manner prescribed, and overnight the kit back to the lab (overnight service is required for accurate bacteria results). Your test results will arrive in approximately two weeks. If you have any questions you can call us any time to interpret the results and recommend appropriate water systems. This kit is exactly the same as our full spectrum test except it does not include pesticides.
