Observations

  • 4 February 2025

    Creek Bend Pond by Lisa O'Brien

    Since last test taken it has been bitter cold. Creeks and pond were frozen, little snow. There was a significant rainfall in last week which measured over 1 inch of rain in some spots. Temperatures have moderated in the last week, with freezing temps overnight. Salt would have been used minimally in the last month due to lack of significant snow. Rain fell on frozen ground and most ran off to open waterways.

    Quantab reading was below the scale so lowest value of ppm was recorded.

    Pond at Briarcliff Neighborhood Beach by Lainey Howard

    The test strip shows 1/4 to 1/2 of a quantab unit which is significantly lower than the lowest unit on the conversion chart, so real result should be between 0-32 ppm (closer to 0)
