Lancaster Hard Water
How Hard Is Lancaster Water?
Lancaster’s water hardness depends on which provider serves your home. Most of the city is served by Los Angeles County Waterworks District No. 40, while Cal Water’s Lancaster system serves part of the area. Cal Water’s most recent water quality report shows its groundwater averaging 101 ppm (range 61–140), or about 5.9 grains per gallon, with purchased State Water Project water from the Antelope Valley-East Kern Water Agency at 95 ppm. A free in-home water test is the best way to know what’s coming out of your tap.

Frequently Asked Questions
Is Lancaster tap water safe to drink?
It depends on your provider. Cal Water’s most recent water quality report for its Lancaster system, which serves part of the city, shows contaminants such as arsenic (3.5 ppb average, range 3.2–3.7 ppb), hexavalent chromium (8.7 ppb average, range 6.1–11 ppb), nitrates (1.8 ppm average, range 1.3–2.3 ppm), and disinfection byproducts like TTHMs (41 ppb average, up to 75 ppb). Most of these are within regulatory limits, but Cal Water discloses that its hexavalent chromium levels exceed California’s 10 ppb maximum contaminant level (MCL). A system of its size is not considered in violation until after October 1, 2028, and Cal Water says it is working to comply. Arsenic and hexavalent chromium are also well above California’s public health goals.
Is Lancaster’s water hard?
Yes. Cal Water’s Lancaster system reports moderately hard water, with groundwater averaging 101 ppm (about 5.9 grains per gallon) and purchased AVEK water at 95 ppm. This can lead to scale buildup on faucets, soap inefficiency, and dry skin or hair.
Does Lancaster’s water contain PFAS (“Forever Chemicals”)?
Cal Water’s most recent water quality report for its Lancaster system does not list any PFAS results, so it doesn’t show whether PFAS are present. A free in-home water test can tell you more, and homeowners concerned about PFAS exposure should consider reverse osmosis or advanced carbon filtration, as these are proven to reduce PFAS.
Does Lancaster add fluoride to its water?
No. Cal Water doesn’t add fluoride to its Lancaster system. Its most recent water quality report shows naturally occurring fluoride averaging 0.40 ppm (range 0.32–0.47 ppm) in the groundwater and 0.06 ppm in purchased AVEK water, below California’s 2 ppm limit.
What other contaminants are in Lancaster’s water?
Cal Water’s most recent water quality report for its Lancaster system detected:
- Arsenic (up to 3.7 ppb)
- Hexavalent Chromium (8.7 ppb average, up to 11 ppb)
- Nitrates (up to 2.3 ppm)
- Copper (not detected)
- Lead (not detected)
- TTHMs (41 ppb average, up to 75 ppb)

Where does Lancaster get its water?
Cal Water’s Lancaster system blends local groundwater from its wells with purchased State Water Project surface water from the Antelope Valley-East Kern (AVEK) Water Agency. Most of the city is served by Los Angeles County Waterworks District No. 40, which publishes its own report.
What is the pH level of Lancaster water?
Cal Water’s Lancaster groundwater averaged pH 7.3 (range 6.5 to 7.9) in the most recent water quality report, and purchased AVEK water averaged 7.0 (range 6.7 to 7.7), which is slightly acidic to slightly alkaline.
Should I use a water filter or softener in Lancaster?
Yes, due to hard water and contaminants such as TTHMs, arsenic, and chromium, many Lancaster residents install whole-house water filters, reverse osmosis systems, and softeners to improve water quality and appliance longevity.
Does Lancaster water have a high total dissolved solids (TDS) level?
Cal Water’s Lancaster groundwater averaged 335 ppm TDS (range 280 to 390 ppm) in the most recent water quality report, and purchased AVEK water measured 310 ppm. That’s below California’s 500 ppm recommended secondary standard, but dissolved solids can still affect taste. Reverse osmosis is recommended to lower TDS levels.

Why Do Lancaster
Homeowners LOVE Us?
Culligan has professional courteous drivers that are in and out in no time to change out my filters. In the SCV it’s a must to protect our appliances from hard water failure and at the same time have clean soft filtered drinking water.
The technician was awesome and solved our issue quickly and perfectly. He told us exactly what we need to do moving forward so as to get plenty of filtered drinking water all the time.
I have been a Culligan customer for over 30 years and have always been pleased with their service. I would certainly recommend them to anyone needing water service.
