MWS has donated an instrument to the Maryland Department of Natural Resources to assist in a special water-quality study of Mattawoman Creek and its tributaries. The instrument, a "conductivity data logger," continuously records how well the water conducts electricity, which is a measure of dissolved salts. The extra meter will greatly enhance the project by allowing comparisons between tributaries. The MWS volunteers also assist in the study by making monthly measurements over the watershed.

Initial results of the study were reported at the annual meeting of the Maryland Water Monitoring Conference held November 13, 2015. The conductance was found correlate with the road density on the land upstream of the measurement location, a signature that road salts are the main cause for elevated stream conductance.
