What is the Water Quality in Lake Charles, Louisiana?
Compared to other US cities, Lake Charles water quality ranks in the middle range for contamination excluding Lead.
Most of their 22 contaminants have cancer-causing attributes.
- Haloacetic acids (HAA5) are at extremely high levels: 47x health guidelines.
- Haloacetic acids (HAA9) are at extremely high levels: 116x health guidelines.
- These are both byproducts of the chlorine treatment process most water supplies go through.
- Radium is at very high levels: 25x health guidelines.
Let’s look closer at what’s in Lake Charles water.
What’s in Lake Charles water?
Here are the top 5 chemical compounds in Lake Charles water and what health issues they can potentially cause:
- Bromodichloromethane – Potential effect: Cancer
- Chloroform – Potential effect: Cancer
- Haloacetic acids – Potential effect: Cancer
- Radium – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are five of the 22 contaminants analyzed by the Environmental Working Group (ewg.org).
12 of these contaminants are rated as exceeding EWG Health Guidelines.
Does Lake Charles water have Lead contamination?
Yes, Lake Charles has lead in its water. The most recent Lead samples collected in 2019 showed concentrations up to 17.0 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.

What Can You Do?
Information about water quality in Lake Charles can be surprising.
But there are things you can do in your home to clean up your water.
To Remove Lead and Other Contaminants In Your Home:
There is one solution that beats Brita, PUR, and some whole house systems.
- It costs less per gallon.
- Needs fewer filter changes.
- And it doesn’t make your water taste weird.
- Use Berkey filters with activated carbon to filter out the majority of contaminants in Lake Charles drinking water.
- To filter out 20 of the 22 contaminants in your whole house, consider a Reverse Osmosis water filtration system for your home.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Barium – health risks in water
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- 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.
