What’s in Downey’s water?
Downey stands out for running one of the region's self-sufficient municipal systems, pumping nearly all of its water from city-owned wells that reach deep into the Central Groundwater Basin. Because this supply is almost entirely local groundwater rather than imported river water, it is naturally rich in dissolved minerals and reliably hard. That hardness is why so many Downey homeowners fight scale on their faucets, cloudy residue on glassware, and dry, tight-feeling skin after showering. The same minerals quietly coat the inside of water heaters and dishwashers, forcing them to work harder. PurAgain filtration removes up to 99% of contaminants, so families across the city enjoy softer, cleaner water at every tap.
The only way to know exactly what’s in your Downey water is to test it, and that in-home test is free.

Downey, in Los Angeles County, runs on imported Colorado River and State Water Project supply that arrives hard and heavily chloraminated.
