Free Microbial Testing Program

Worried about bacteria in your well or home water? Bring a sample to our Kennewick shop and we will test it for total coliform in our own lab, at no charge. Microbial testing is a drop-off service; we do not collect bacteria samples at your home.

  • Drop off your sample at 4819 W Clearwater Ave, Kennewick, Monday through Friday, 8:00 AM to 5:00 PM.
  • We incubate it for 48 hours alongside a bacteria-free control sample.
  • Read the result. Purple means no total coliform was detected. Yellow means coliform is present and we will recommend treatment, such as UV disinfection.

We just had installed a very elaborate filtration system for our well water. Matt was very knowledgeable and did an excellent job with the installation. Our water tastes fabulous!

Marcy Roop

The soft water system installed and maintained by Soft Water Specialists has been working great resulting in no hard water deposits on shower/fixtures. The staff is courteous and prompt with routine preventive maintenance and inspections.

John Geuther

Incredible professionalism and a great installation experience. Pricing was great and I canโ€™t even think of the words good enough to recommend Chris and Soft Water Specialists. We are extremely pleased with our purchase. If youโ€™re contemplating a water softener and/or filtration system we highly recommend them.

Frequently Asked Questions

They solve different problems. A softener addresses hard water minerals. A filter targets things like chlorine, sediment and taste. Many homes benefit from both. Find your ideal water system.

A site survey is needed to properly assess your situation, and every system is customized for each client based on their needs. Weโ€™ll come out, test your water and give you a custom quote. See how much a water softener costs for more.
