Sodium in Nevada well water
In Nevada, sodium was detected in 100% of 4,396 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.
Check your sodium number
Type the value from your lab report. It is compared to the EPA limit, the same way the full interpretation does it.
Test your Nevada well for sodium
Certified lab analysis of your own tap water, bottles and prepaid return shipping included. The Essential well panel covers arsenic, uranium, nitrate, lead, copper, manganese, iron, sodium and bacteria; radon and PFAS are add-ons.
