Water sampling in Accotink Cr

Assistant researcher Mahdi Mojarrad and I visited Accotink Creek this morning to conduct our normal quarterly water quality monitoring for Fairfax City. It was a very chilly morning and there was ice covering much of the creek.

In one place along Daniels run we had to break through the ice with our sledgehammer.

The water looks very clear but the temperature was barely above freezing and the conductivity was elevated due to road salt runoff.
