What the 2025 Modesto water report can—and cannot—tell you
The City of Modesto’s 2025 Consumer Confidence Report covers Modesto System 5010010, including Empire. The City says the system met applicable federal and state drinking-water standards. It also reports that approximately 40% of the water supplied in 2025 came from groundwater wells and 60% from surface water treated at the Modesto Reservoir plant before mixing in the distribution system.
The same report lists utility-wide monitoring results, including average hardness of 199 parts per million as calcium carbonate and a reported range of 33–388 ppm. That range matters: a citywide average cannot establish the hardness or other conditions at one house. The free Water Report uses public records to create a practical starting point, then asks you to confirm the provider and PWSID on the current bill.
This is not a laboratory test of water from your tap. Current provider records, source blending, the home’s plumbing and goals, household and bathroom sizing, installation conditions, and model-specific performance still control the final recommendation.

A two-minute starting point for a Modesto address
Use the City’s utility-wide report as context, then run the free ZIP lookup to confirm the likely supplier and continue to household sizing, installed price, financing, and optional contact.
2025 source mix
The City reports approximately 40% groundwater and 60% treated surface water, which then mix in the distribution system.
Average reported hardness
The utility-wide range was 33–388 ppm as CaCO3. An address-specific result can differ from the reported average.
City compliance statement
The City says its water met applicable federal and state standards; detection does not automatically mean a violation or tap-specific risk.

Public monitoring records are not a laboratory sample from your faucet. Provider confirmation, the current official source, property plumbing and goals, household sizing, installation conditions, and model-specific performance still control the final recommendation.
A useful place to begin
Call about a Modesto property when…
You see scale or spotting and want to compare the city’s reported hardness context with whole-home softening.
You are researching what is in Modesto tap water and want the official public report explained in plain English.
You want to compare a whole-home path with dedicated reverse osmosis for drinking and cooking water.
You want installed pricing and financing availability before speaking with a sales representative.
Before equipment is selected
Three decisions that shape the local plan
Confirm the provider
ZIP codes and utility boundaries do not match exactly. Check the supplier and PWSID on the current water bill before relying on a utility report.
Separate the goals
Softening, whole-home filtration, and kitchen reverse osmosis do different jobs. The proposed components should be tied to the stated issue without claiming universal contaminant removal.
Size and verify
Household size, bathrooms, main-line access, drainage, power, cabinet space, and model-specific performance shape the final equipment and installation scope.
