What a great evening (February 24, 2016) sharing our aquatic work with the folks at Gregg school in Corning,NY.!!! Students enjoyed the digital microscopes, doing transparency testing, and water surface tension testing. Prior to the event I collected water from the Chemung River and did several chemical tests.
pH 7.5 slight base
TDS 134 ppm
Hg .oo1 ppm
metals under 10 ppm
nitrate nitrogen 2ppm (concern)
surface tension 27 drops (Gregg student data
