What it means in Linden
Sodium above the guideline
Sodium ranged from 32 to 99 ppm in 2025, so at its highest it was about twice the 50 ppm recommended upper limit. The report says that matters mainly for people on a sodium-restricted diet.
1,2,3-trichloropropane
This solvent, used in paint removers and degreasers, measured 0.01 to 0.02 ppb. New Jersey's limit is 0.03 ppb, so the water passed with little room to spare.
Nitrate well below the limit
Nitrate measured 0.6 to 2 ppm against a limit of 10 ppm. Above 10, nitrate is a health risk for infants under six months old.
