- Total trihalomethanes – Potential effect: Cancer
These are five of the 31 contaminants analyzed by the Environmental Working Group (ewg.org).
12 of these contaminants are rated as exceeding EWG Health Guidelines.
Does San Angelo water have Lead contamination?
Yes, San Angelo has lead in its water. The most recent Lead samples collected in 2018 showed concentrations up to 3.7 parts per billion (ppb).
The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.
- Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.
There is no safe level of lead for humans.
- The good news is that 99.99% of the lead can be removed.

Conclusion – What Can You Do?
Information about water quality can be surprising.
But there are things you can do in your home to clean up your water.
- Test Your Water using Varify Home Test Kits or similar.
- To Remove Lead and Other Contaminants In Your Home:
- Use Activated Carbon filters to remove most contaminants in your drinking water.
- To filter out even more contaminants, consider a Reverse Osmosis water filtration system for your house.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Arsenic – health risks
- Barium – health risks in water
- Bromochloroacetic acid
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Cyanide – exposure limits
- Dibromoacetic acid
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Monobromoacetic acid
- Selenium – health risks
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
- Our recommendation: APEC Reverse Osmosis Systems
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
