Fluoride in New Mexico well water
In New Mexico, 8% of 10,366 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.

Type the value from your lab report. It is compared to the EPA limit, the same way the full interpretation does it.
