    North Aurora Riverfront Park by Maura Canzano

    Incorrect units on Post-It (3.8 Quantab Units = 138 ppm)

  • 8 December 2024

    Timber Ridge Forest Preserve by Andy Culbertson

    A muskrat swam to the stream bank and cleaned itself for several minutes. On the smaller streams that fed into the creek, there was some ice on the edges of the water. I forgot to pour out a couple of vial-fulls to clean the vial this time before testing a sample. On the test strip there was a small pale patch above the 3.6 line, but there seemed to be a gap under it, so I didn't count it in the reading.

    River Park Boathouse by Susanna Lang

    I thought a lot of foamy stuff had been released into the canal which enters the river just north of my test site but it was ice! Very cold until recent days. Otherwise the river seemed as usual in winter—mallards, gulls, a great blue heron about a quarter mile south, human fishermen, calm water.
