    It's hard to see in the photo but the tip of the white test strip just surpases the 4.0 and thus rounded up to 4.2 (172 ppm).

    Rock Run Creek by Andy Neill

    Photos include North and South views from foot bridge sample site. The other two photos were taken in a neighborhood a few blocks east of Essington Road and Rock Run Creek on Cassie Drive. This water runoff likely makes its way into the Rock Run Creek. Note the intermittent stream flows between suburban houses and under the Cassie Drive by a culvert. Driveways and roadways are likely salted regularly in this neighborhood.

    Lippold Park - West Entrance by Far Syed

    After the rain from last night, I went to collect the sample today, and it seems like due to the rain, the chloride increased significantly, while the pond was moving smoothly. The sky was a pretty site too, and not too windy!

    Round Meadow Lake by Jane Barnett

    Above freezing days for the past week have freed this lake from its December ice cover! The temperatures are heading lower again, so this may be the only time it will be free from ice this month.
