Drinking Water Quality: Hardness

How are total dissolved solids (TDS) measurements used to evaluate drinking water quality? In this investigation, students use a conductivity sensor to relate total dissolved solids (TDS) measurements with drinking water quality. Students can compare treated drinking water with natural water sources.
