Riverside Water Quality: What's Really in Your Tap Water

Riverside Public Utilities serves most of the city with groundwater pumped from the Bunker Hill and Riverside basins, so Riverside's water reflects what's in the local aquifers. Some neighborhoods on the edges of the city are served by Western Water or other districts. The water meets state and federal standards, but it's hard, and EWG lists 10 contaminants above its stricter health guidelines, including nitrate, arsenic, chromium-6, PFAS, radium and uranium.

Sources: EWG Tap Water Database, City of Riverside (PWS CA3310031), 25 contaminants detected and 10 above EWG guidelines, 2013 to 2024 data; and Riverside Public Utilities' 2025 Water Quality Report (hardness 197 mg/L average, range 180 to 210; nitrate 5.4 mg/L average against a 10 mg/L legal limit; arsenic 3.3 µg/L; chromium-6 2.1 µg/L; uranium 6.1 pCi/L; chlorine disinfection). All results were below state and federal legal limits; EWG health guidelines are stricter, health-based goals. Contaminants marked for the RO faucet are reduced in your drinking and cooking water at the kitchen sink.

Softening and soap savings

Hard Water Savings Calculator for Riverside Households

Hard water quietly costs you money on energy, appliances, fixtures, plumbing and soap, and bottled water adds up fast. Here's what an average Riverside household on hard water can expect to save with our complete system, based on independent studies.

Pick your household size to update the estimates.

Lower Water Heater Bills

$100/year
The research

Battelle: tank water heaters lose about 4% efficiency for every 5 grains of hardness. Soft water also lets you wash in cold water.

Longer-Lasting Appliances

$90/year
The research

Water heaters, dishwashers and washing machines last longer without scale. In Battelle tests, tankless heaters failed from scale in 1.6 years of use on 26 gpg water.

Clear Faucets and Showerheads

$50/year
The research

Battelle: showerheads on hard water lost 75% of their flow in under 18 months of use.

Fewer Plumbing Repairs

$60/year
The research

Less scale inside pipes, valves and toilet parts means fewer repair calls and descaling jobs.

Half the Soap and Detergent

$150/year
The research

WQRF study: soft water cut laundry detergent by 50% and dishwasher detergent by 50% or more in very hard water.

No More Bottled Water

$250/year
The research

Americans drink 47.3 gallons of bottled water per person each year. Your included 8-stage RO faucet replaces it with purified water from the tap.

What a Riverside Home Spends vs. Saves, Year by Year

The blue line is everything you spend: the $3,399 system plus salt and RO filters every year. The green bars are what you save. Once the bars pass the line, the system has paid for itself.

Pays for itself
Year 6

Tap any year on the chart to see its numbers. Upkeep uses about $70 a year in softener salt for a 3 to 4 person home and about $80 a year in RO filters.

How we estimate this: averages for a household on about 20 gpg water, before price increases. Energy uses Battelle's finding of about 4% water heater efficiency loss per 5 gpg plus cold-water washing. Appliance and fixture figures spread replacement costs over shorter lifespans on hard water. Soap figures use WQRF's 50% detergent reduction for laundry and dishes. Bottled water uses 47.3 gallons per person per year at about $1.50 per gallon for bulk cases, replaced by the included reverse osmosis faucet. Figures are gross savings and do not include softener salt or RO filter replacement costs. Your actual savings depend on your home, water use, appliances and local rates.

Riverside FAQs

Riverside Water Questions, Answered Locally

Is Riverside water hard?

Yes. Riverside Public Utilities' 2025 Water Quality Report shows average hardness of 197 mg/L, with a range of 180 to 210 mg/L. That's about 12 grains per gallon, very hard by Water Quality Association standards, which is why Riverside homes see scale on fixtures and inside water heaters.

Where does Riverside's water come from?

Riverside Public Utilities supplies most of the city with local groundwater pumped from the Bunker Hill and Riverside basins. Some neighborhoods on the edges of the city are served by Western Water or other districts, so check your water bill.

Does Riverside water have chlorine or chloramine?

Riverside Public Utilities disinfects with chlorine, averaging 0.58 mg/L in its latest report. Our catalytic carbon removes chlorine at every tap, along with the taste and smell it leaves behind.

How much nitrate is in Riverside water?

The utility's latest report shows nitrate averaging 5.4 mg/L, with a range of 4.7 to 6.5 mg/L, against a legal limit of 10 mg/L. EWG's health guideline is much lower. Carbon filters and water softeners don't remove nitrate, but our 8-stage reverse osmosis faucet reduces it in your drinking water.

What contaminants are in Riverside tap water?

EWG's Tap Water Database lists 10 contaminants above its health guidelines for the City of Riverside: nitrate, arsenic, chromium-6, PFOA, PFOS, PFHxS, radium, uranium, TTHMs and HAA9. All were below legal limits. The utility's report shows chromium-6 averaging 2.1 µg/L against California's 10 µg/L limit.

Does Riverside water have PFAS?

EWG lists PFOA, PFOS and PFHxS above its health guidelines for Riverside, at levels below current legal limits. Catalytic carbon and reverse osmosis both reduce PFAS.

Which areas near Riverside do you serve?

All of Riverside, plus Jurupa Valley, Moreno Valley, Corona and Norco, and down the I-215 to Murrieta and Temecula.

What does water treatment cost for a Riverside home?

Our Mixed Bed Water Softener with Catalytic Carbon + 8-Stage Reverse Osmosis is $3,399 installed during our 40% off offer, down from $5,665, or from $60 a month with financing on approved credit. Your exact price is confirmed in writing after your free water test.
