OCWA's 2024 Consumer Confidence Report states that the hardness of its water ranges from 115 to 190 parts per million, equal to about 6 to 11 grains per gallon, which it describes as moderately hard, and that the pH runs from 7.1 to 8.7 with alkalinity from 95 to 140 milligrams per liter as calcium carbonate. It adds that softening does not improve the sanitary quality of water, that softeners mostly remove calcium carbonate and stop spotting and scaling, and that softeners may increase water usage because it takes more soft water to rinse away soap.

Clay address, and not sure what you are dealing with?
Describe what the water or the heater is doing. In a town with no confirmed lead, the answer is usually something ordinary and findable.
What replaces the lead question in Clay
Start with what Clay does not have. On the state inventory the town records zero confirmed lead service lines across 13,573 lines, with a further 5,615 records under a second Clay locality all classified non lead. That is a publishable negative and it is worth saying plainly rather than hedging it. What Clay does have is 593 galvanized lines requiring replacement, and in 585 of them the public half is already copper, so the conversation here is pressure and rust on the customer side. The housing stock is the newest large one in the metro: a median build year of 1978 across 26,282 units, only 3.2 percent built before 1940, and Radisson at a median of 1990. That moves the agenda to the things that age together in a 1970s or 1980s house, which is original supply valves, hose bibs and a water heater now on its second or third replacement. OCWA rates its water at 115 to 190 parts per million hardness, six to eleven grains a gallon, enough to scale a tank over years and not enough to make a softener a health purchase. The authority says that itself, which is useful to have in mind if a softener appears on a water heater quote.
