You can prevent chloride pollution from salt in fresh water by making sure that your water softener is operating as efficiently as possible and that you aren't using more soft water than you need. There are several factors that go into water softener efficiency. Some factors are complicated and require a professional opinion, but there are some factors that it's possible for you to assess on your own.
The District developed the self-screen survey below to help residents identify opportunities to reduce salt use in their home. By taking this self-screen, you'll get recommendations for actions you can take to reduce salt use based on the information you enter about your softener and soft water use. You can use this information to contact a water softener service professional to make the recommended adjustments to your softener.
