Water Quality in McKinney, Texas
Watershed: Clemons Creek – East Fork Trinity River
What is the water quality like in McKinney, TX?
Let’s dive deeper into what’s in McKinney water.
What’s in McKinney water?
Here are the top 7 chemical compounds in your water and what health issues they can potentially cause:
- Arsenic – Potential effect: Cancer
- Bromodichloromethane – Potential effect: Cancer
- Chloroform – Potential effect: Cancer
- Haloacetic acids – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Radium – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are seven of the 33 contaminants analyzed by the Environmental Working Group (ewg.org).
16 of these contaminants are rated as exceeding EWG Health Guidelines.
See the What Can You Do? section below for all of the contaminants you can filter out and how to do it.
Where does McKinney’s water come from?
McKinney’s water comes from the Clemons Creek – East Fork Trinity River watershed.
One of the two EPA assessed water sources in the Clemons Creek – East Fork Trinity River watershed is in Impaired condition. This is the East Fork of the Trinity River itself.
Ideally, a water source would be rated in Good condition. Lake Lavon to the southwest of McKinney is Good condition.
Whether a water source is in Impaired or Good condition refers to the quality of these uses:
- Drinking Water
- Aquatic Life
- Fish and Shellfish Consumption

Conclusion – What Can You Do?
Information about water quality can be surprising.
But there’s no reason to lose hope. There are things you can do in your household as well as things you can do at a community level.
In Your Household:
- Use Berkey filters with activated carbon to filter out 26 of the 33 contaminants in your drinking water.
- Berkey filters can also remove up to 99.99% of Lead in McKinney water.
- Brita can filter 16 contaminants (and Lead depending on the filter).
- Note: We may receive a commission if you decide to purchase filters through links on this page.
- To filter out 30 of the 33 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
- Atrazine – herbicide
- Barium – health risks in water
- Bromochloroacetic acid
- Bromodichloromethane – health risks in drinking water
- Chlorite – change in blood chemistry
- Chloroform – side effects
- Chromium (total)
- Cyanide – exposure limits
- Dibromoacetic acid
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Monobromoacetic acid
- Monochloroacetic acid
- Selenium – health risks
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
*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.
