Sodium in New Mexico well water
In New Mexico, sodium was detected in 100% of 8,202 tested private well samples.
Sodium enters wells with road salt and from softeners. EPA's guidance level of 20 mg/L matters for people on sodium-restricted diets; most people are not affected below 250 mg/L.

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