"Here in our office, when you bring in a water sample we're measuring conductivity and conductivity measures water's ability to carry electricity. If you remember way back to your chemistry classes, different minerals carry different charges. Those charges add up together to make ypur conductivity."
"When we measure conductivity, we've seen enough samples here that we're able to make some assumptions based on that number," said Lang, "So sulfate makes up about 50% of the conductivity, and we know that TDS, or total dissolved solids, can account for probably 85-90% of the conductivity number."
Lang tells people that while they may have TDS meters on hand that can be useful, many are calibrated for water not from Saskatchewan and as such will display incorrect results.
