How Hard Is Palmdale Water?
Palmdale’s tap water is moderately hard. Palmdale Water District’s most recent water quality report shows treated surface water, about 71% of what the district delivered that year, averaging 6.5 grains per gallon (range 5.6–7.4). Groundwater averages 6.8 grains per gallon but varies widely from well to well, from as low as 1.9 up to 15 grains per gallon.
Where Can I Get A Water Quality Report?

Frequently Asked Questions
Is Palmdale tap water safe to drink?
Yes, Palmdale Water District’s most recent water quality report shows its water meeting all health-based state and federal drinking water standards. However, some contaminants were detected, including hexavalent chromium (groundwater average 4 ppb, up to 9 ppb), nitrate (groundwater average 2 ppm, up to 6 ppm), and total trihalomethanes (TTHMs; highest running annual average 67 ppb, with individual samples up to 89 ppb). Compliance is based on running averages, so these levels are within regulatory limits, but many residents choose additional filtration for drinking water.
Is Palmdale’s water hard?
Yes, Palmdale water is classified as moderately hard, with treated surface water averaging 6.5 grains per gallon (gpg) and groundwater averaging 6.8 gpg, ranging from 1.9 to 15 gpg depending on the well. Hard water can cause mineral buildup on fixtures and reduce appliance efficiency.
Does Palmdale’s water contain PFAS (“Forever Chemicals”)?
Palmdale Water District’s most recent water quality report shows PFAS averaging non-detect under the EPA’s UCMR 5 testing. A few samples, mostly from groundwater, showed trace amounts of PFBS, PFHxA, and PFPeA, at 6 parts per trillion or less. However, because PFAS are persistent in the environment, many residents consider reverse osmosis or advanced carbon filtration systems for additional protection.
Does Palmdale add fluoride to its water?
No. The water quality report does not describe adding fluoride. Palmdale’s water contains naturally occurring fluoride: according to the latest report, treated surface water averaged 0.1 ppm and groundwater averaged 0.2 ppm (up to 0.5 ppm), well under the 2.0 ppm state limit.
What other contaminants are in Palmdale’s water?
The most recent water quality report identified the following trace contaminants:
- Hexavalent Chromium (groundwater average 4 ppb, up to 9 ppb; California limit 10 ppb)
- Vanadium (groundwater average 16 ppb, up to 48 ppb)
- Nitrate (groundwater average 2 ppm, up to 6 ppm)
- TTHMs (highest running annual average 67 μg/L, individual samples up to 89 μg/L)
- HAA5 (highest running annual average 10 μg/L, up to 13 μg/L)
- TDS (groundwater average 254 ppm, up to 540 ppm)
Where does Palmdale get its water?
Palmdale’s water comes from a mix of surface water and groundwater sources. Surface water from the State Water Project and Littlerock Reservoir is stored in Lake Palmdale and treated at the Leslie O. Carter Water Treatment Plant, while groundwater is pumped from the Antelope Valley groundwater basin. According to the most recent water quality report, about 71% of deliveries were treated surface water and 29% were groundwater, all treated and monitored by the Palmdale Water District.
What is the pH level of Palmdale water?
The pH of Palmdale’s water ranges from 6.8 to 8.4, which is considered neutral to slightly alkaline. Treated surface water averaged 7.2 and groundwater averaged 8.2, according to the most recent water quality report.
Should I use a water filter or softener in Palmdale?
Yes, due to hard water and trace contaminants such as TTHMs, hexavalent chromium, and nitrates, many Palmdale residents choose whole-house water filters, reverse osmosis systems, and water softeners for improved water quality and appliance protection.
Does Palmdale water have a high total dissolved solids (TDS) level?
Generally not. Palmdale’s treated surface water averages 250 ppm TDS and its groundwater averages 254 ppm, ranging from 150 to 540 ppm depending on the well, according to the most recent water quality report. Averages are well under California’s 500 ppm recommended limit, though the highest wells exceed it (the upper limit is 1,000 ppm), which may affect taste. Reverse osmosis systems are recommended to reduce TDS.

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.
