Georgetown TX Water Quality Report Explained — What Every Homeowner Needs to Know

Updated August 2026  •  (737) 738-8111

The most important number in Georgetown’s water quality report for homeowners: 440 mg/L (25.8 GPG) — total hardness. This single measurement explains why your water heater failed early, why your showerhead is clogged, and why your Georgetown plumber’s estimate is higher than you expected.

Where Georgetown’s Water Comes From

Georgetown’s municipal water supply comes from two sources: the Edwards Aquifer and the Lake Georgetown Reservoir. The Edwards Aquifer supplies the majority of Georgetown’s water and is responsible for its high mineral content — rainwater percolates through Cretaceous-era limestone for thousands of years before reaching the aquifer, dissolving calcium carbonate and magnesium in the process.

The City of Georgetown then adds chloramine (a combination of chlorine and ammonia) to disinfect the water, and adjusts pH for corrosion control. The water meets all EPA safety standards. But softening is not performed — the hardness level you receive is the natural hardness of the Edwards Aquifer.

What the Report Doesn’t Tell You — But Should

The City of Georgetown’s Annual Water Quality Report fulfills EPA regulatory requirements — it tells you the water is safe to drink. What it doesn’t explain is the practical impact of these measurements on your home:

440 mg/L hardness means: your water heater will fail at 6–9 years instead of 10–12. Your showerhead will lose 50–75% of flow within 18 months. Your dishwasher and washing machine will work harder and wear faster. White scale will appear on every fixture and glass surface.

Chloramine means: if your water heater has a standard magnesium anode rod, Georgetown’s water chemistry will cause hydrogen sulfide production — the rotten egg smell many Georgetown homeowners report from hot water.

pH 7.5–8.2 means: slightly alkaline water, which can contribute to a specific type of copper pipe corrosion called “blue-green staining” — a greenish residue on fixtures indicating copper dissolution from supply pipes.

How to Get Georgetown’s Annual Water Quality Report

The City of Georgetown mails the Consumer Confidence Report (CCR) annually to all water account holders. It’s also available on the Georgetown Utilities website at Georgetown.org. The report covers all measured contaminants, violations (if any), and source water information. Look for “Total Hardness” in the secondary standards section — it will confirm the 440 mg/L figure.
