- People monitoring saltwater intrusion in drinking-water sources
- Worth noticing
- The page labels sodium as an estimate from conductivity and says it is most accurate where salt water is the main source.
Field notes
Saltline lists two pipe modules with estimated sodium levels, temperature, conductivity, and last-seen timestamps. Both modules are marked offline: one reading is 33 hours old and the other 24 hours old. The page groups sodium values below 200 mg/L as safe, 200–600 as elevated, and above 600 as unsafe; it notes that the estimate is based on conductivity calibrated with table salt.
