Newport Beach Hard Water
How Hard Is Newport Beach Water?
Newport Beach’s tap water is very hard. The City of Newport Beach’s most recent water quality report shows local groundwater averaging 232 ppm, or about 14 grains per gallon, with readings ranging from 47.5 to 475 ppm (about 2.8–28 gpg). Imported water from the Metropolitan Water District is just as hard, averaging 236 ppm (about 14 gpg). The city’s supply is about 85% groundwater and 15% imported water. Some neighborhoods are served by Mesa Water District or the Irvine Ranch Water District instead, so check your water bill to confirm your provider.

Frequently Asked Questions
Is Newport Beach tap water safe to drink?
Yes, Newport Beach’s tap water meets all state and federal safety standards, and the most recent water quality report lists no violations. However, some contaminants were detected in local groundwater, including uranium (average 4.58 pCi/L, up to 12.9 pCi/L), nitrate (average 1.5 ppm, up to 3.3 ppm), and hexavalent chromium (average 0.2 ppb, up to 0.32 ppb). While these levels are within regulatory limits, uranium and hexavalent chromium are above California’s non-enforceable public health goals.
Is Newport Beach’s water hard?
Yes, Newport Beach’s water is classified as very hard. Local groundwater averages 232 ppm (about 14 gpg), ranging from 47.5–475 ppm, and imported MWD water averages 236 ppm (about 14 gpg). Hard water can cause scale buildup on fixtures, dry skin, and reduced appliance efficiency.
Does Newport Beach’s water contain PFAS (“Forever Chemicals”)?
The City of Newport Beach’s most recent water quality report doesn’t list PFAS results, so it doesn’t show whether PFAS are present in the city’s supply. Because PFAS contamination has been found in parts of the Orange County groundwater basin, many residents choose reverse osmosis or advanced carbon filtration systems for added protection, and a free in-home water test can tell you more about your tap.
Does Newport Beach add fluoride to its water?
Newport Beach’s groundwater contains naturally occurring fluoride averaging 0.4 ppm, and the imported MWD water in the city’s blend is fluoridated by MWD to about 0.7 ppm, within state and federal guidelines.
What other contaminants are in Newport Beach’s water?
The most recent water quality report detected several trace contaminants, including:
- Uranium (groundwater average 4.58 pCi/L, up to 12.9 pCi/L)
- Nitrate (groundwater average 1.5 ppm, up to 3.3 ppm)
- Arsenic (up to 3.8 ppb)
- Hexavalent Chromium (groundwater average 0.2 ppb, up to 0.32 ppb)
- TTHMs (average 22 ppb, up to 33 ppb)
- HAA5 (average 14 ppb, up to 22 ppb)
- TDS (groundwater average 388 ppm, up to 726 ppm; imported MWD water average 545 ppm)
Where does Newport Beach get its water?
Newport Beach’s water is a blend of about 85% groundwater and 15% imported surface water. Groundwater comes from four city wells in Fountain Valley that draw from the Orange County groundwater basin, managed by the Orange County Water District, and is pumped to a reservoir in Newport Beach. Imported water from the Colorado River and Northern California comes through the Metropolitan Water District (MWD).
What is the pH level of Newport Beach water?
Newport Beach’s local groundwater averages a pH of 7.9 (range 7.7–8.2), and imported MWD water averages 8.3, which is considered neutral to slightly alkaline.
Should I use a water filter or softener in Newport Beach?
Yes, due to hard water and the presence of trace contaminants, many residents benefit from whole-house water filters, reverse osmosis systems, and water softeners to enhance water quality, taste, and appliance longevity.
Does Newport Beach water have a high total dissolved solids (TDS) level?
It can be. Newport Beach’s local groundwater averages 388 ppm TDS (range 122–726), while imported MWD water averages 545 ppm (range 465–625), above the 500 ppm level California recommends for taste. Reverse osmosis is recommended for reducing TDS for better-tasting drinking water.

Why Do Newport Beach
Homeowners LOVE Us?
I couldn’t believe how hard our installation person worked to get the whole house filter installed. You couldn’t pay me enough money to crawl all the way under the house! I am really enjoying the peace of mind that I have clean drinking water for my senior parents, myself, and my dog. Highly recommend.
All of the employees at Culligan have been very helpful with getting me and my family taken care of. I definitely recommend this office for your water needs.
We got a whole house purification system, water softening system and a reverse osmosis system. Installation was quick and clean and anytime we had a problem, Culligan was quick to send someone out and fix it.
