Water filtration in Cedar Park
Cedar Park gets all of its water from Lake Travis. The city treats it at its own plant and at the regional Brushy Creek plant it shares with Round Rock and Leander.
Lake Travis water is a good source, but by the time it reaches your house it's hard and carries chloramine. Both are easy to deal with once you know the numbers.

Hard water at 183 ppm
Cedar Park's 2025 report lists hardness at 183 ppm, about 10.7 grains per gallon. That's just over the line into very hard.
Expect white scale on fixtures and spotting in the dishwasher. A softener makes the biggest visible difference here.
Chloramine at higher levels
The city disinfects with chloramine. Its 2025 average was 3.09 ppm, on the higher end for the area. If the taste or smell bugs you, catalytic carbon filtration is the fix.
The 2025 report also says the city found no PFAS compounds above reporting levels in federal UCMR5 testing.
