If your tap water appears white, cloudy, hazy, or has a slightly “milky” appearance, you are probably experiencing a condition known as “entrained air.” This condition is harmless and is almost always caused by air in the water. One of the many properties of water is its ability to dissolve gases – including air. Sometimes the air comes back out of the water in the form of many tiny bubbles, giving the water a “milky” appearance. If your tap water is “milky” and you want to confirm whether or not you are experiencing entrained air, rinse out a clear glass twice and then fill it with cold tap water. After a few moments, the water should begin to clear from the bottom of the glass to the top as the bubbles rise to the surface. This is a completely natural occurrence and is harmless. If your water does not clear after 5 minutes, please call our office and we will be happy to assist you. For questions about your water, do not hesitate to contact Customer Service at (909) 875-1804. The Water Quality Supervisor is also available at (909) 875-1804, ext. 371.

Unfortunately, Southern California has hard water. We do not soften the water at this time as it is very costly, the brine waste from treatment is hard to dispose of, and the softening process makes the finished water high in salts – which can be harmful to customers with low sodium diet restrictions. Soft water is also very corrosive to our system and can cause damage to infrastructure and internal plumbing.

If you have any other questions about your water quality, our Consumer Confidence Report can be found online at http://www.westvalleywaterquality.org/ or the Water Quality Supervisor directly at (909) 875-1804 ext 371.
