Survey Introduction

In June 2016, surface water from the Sacramento River was introduced into the City of Davis water distribution system. Surface water is naturally softer than local groundwater. In 2015, before the switch to surface water, the average level of water hardness (weighted average) was 306 ppm (17.9 grains per gallon). In 2018, the average hardness (weighted average) was 74 ppm (4.3 grains per gallon).

The purpose of this survey is to receive feedback from the Davis community on the use of water softeners and any adjustments that have been made in water softener usage due to the change in water hardness.

If you complete the survey and provide an e-mail address, you will be entered into a weekly raffle for an environmental kit.
