Beware of Water Treatment Scams

It is important you are made aware that false claims, deceptive sales pitches, or scare tactics have been used by some water treatment companies. If you have questions regarding water testing please contact 909-334-3508. If you are considering the purchase of a home water treatment system, we recommend the following:

  • Make sure the treatment system/device you are considering is certified to achieve the results being claimed. Reliable certifiers include: NSF International, Underwriters Laboratories (UL), and the Water Quality Association (WQA)
  • Make sure the treatment system/device actually addresses whatever issue you are concerned about - no one system will treat all water quality problems
  • Work with a reputable water treatment company
  • Verify that the installation is done by a licensed plumber or licensed water conditioning contractor (as required by state law)
  • Compare water treatment systems and prices
  • If you are contacted by a company to test your water and they say they are working with the city or a state agency, ask for their contact person at the agency and call to verify
  • Make sure you understand how to properly use and maintain the system; otherwise it may not work properly and, in some cases, can even make your water quality worse. Be wary of companies claiming their system is maintenance-free

Beware of any sales pitch that involves:

  • Reciting a list of recent groundwater contamination problems across the state, regardless of whether the contamination actually affects our area or not
  • Conducting a series of in-home "water quality tests" that the salesperson claims indicate the presence of contamination, when in fact they may simply indicate the presence of naturally occurring minerals in the water
  • Misrepresenting state and federal drinking water standards, claiming the resident's water exceeds those standards, and implying the water is unsafe to drink
  • Offering a "one-time only" offer of a water treatment system at a "greatly reduced" price, when in fact the systems may be sold at inflated prices

If you believe you have been provided false or misleading information please refer to the current Water Quality report for verification.
