Quantification of Salt Concentration in Water Bodies Using Sensor Technology

Abstract (Summary)

Chloride-based deicers have been the primary products used for the winter maintenance operations in the U.S. Deicers/Salts mixes with rain and snowmelt and are transported to local water bodies lakes and streams, which will have a detrimental impact on the water quality. An increase in chloride concentration in the water bodies is toxic to most of the aquatic species. We monitored high resolution (15 minutes) salt concentration for a relatively long time period (winter and spring months) using low-cost sensors at water bodies in Madison County, Illinois. We calibrated sensors using different standard NaCl solutions. Our validation results showed sensors were able to predict salt concentrations in both laboratory and field settings within the precision level required to quantify salt concentration in water bodies. The concentration of salt in water bodies increased in the winter season, which may be attributed to winter road maintenance practices using deicing. Furthermore, we found that the salt concentrations were noticeably high for ephemeral drains/streams within the urban setting compared to perennial streams
