Frequently Asked Questions

Is there barium in Louisiana water?

Louisiana has 5,089 public water systems. 3016 have recorded barium violations based on EPA SDWIS data. If you are on a private well, your water is not covered by these regulations and should be tested independently.

How can I check my Louisiana water for barium?

Search for your water system using the WaterCheck system lookup, or contact your utility and request a copy of your Consumer Confidence Report (CCR). The CCR is published annually and lists all detected contaminants, their levels, and the EPA MCLs. For private wells, contact a state-certified lab for independent testing.

What is the EPA limit for barium?

The EPA Maximum Contaminant Level (MCL) for barium is 2 mg/L. Systems that exceed MCLs are required to notify customers and take corrective action.
