Questions
Frequently asked questions
Is Canyon Lake tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Canyon Lake, PFOS 5.2 ng/L (limit 4 ng/L) and PFHxS 12.5 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing; the lead 90th-percentile result was 1.4 µg/L against the 15 µg/L action level. SJWTX TRIPLE PEAK PLANT (PWSID TX0460172) has a Purity Score of 68/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
Who provides tap water in Canyon Lake?
SJWTX TRIPLE PEAK PLANT (PWS ID TX0460172) is the public water system on record for Canyon Lake, Texas, serving about 32,973 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Canyon Lake get its drinking water?
Surface water (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Canyon Lake's water?
Yes. In EPA's UCMR 5 testing (2024-01-23 to 2024-11-25), PFOS was measured at 5.2 ng/L against a 4 ng/L federal limit and PFHxS was measured at 12.5 ng/L against a 10 ng/L federal limit. PFBS (6.4 ng/L, below the 2,000 ng/L EPA health advisory) was also detected. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Canyon Lake's tap water?
SJWTX TRIPLE PEAK PLANT's most recent lead 90th-percentile result (2023–2025) was 1.4 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
What does the latest Canyon Lake water report show?
PurityMap's current record for Canyon Lake holds 31 findings: 3 above a reference, 2 detected within the reference and 26 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where SJWTX Triple Peak Plant reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at SJWTX Triple Peak Plant: 1.4 µg/L (90th percentile, 2023–2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
