Fluoride in Louisiana well water
In Louisiana, 0% of 97 tested private well samples exceeded the EPA limit for fluoride (4 mg/L).
Natural fluoride in bedrock wells can exceed the limit. Above 4 mg/L long-term exposure causes skeletal fluorosis; above 2 mg/L children can develop tooth mottling.
Check your fluoride number
Type the value from your lab report. It is compared to the EPA limit, the same way the full interpretation does it.
Getting it fixed
