My yard and house plants are watered with water from wells owned by my neighborhood - the water is chlorinated. The water has so much dissolved solids, I spend a couple hours a week cleaning the mister nozzles in my greenhouse to keep them functioning. My soap won't raise a lather. It only rains for a couple months in winter. I've not noticed my potted plants or my yard landscaping suffering for it. If your plants are doing fine, don't worry about the water.
