Split Samples. An industry and a municipal wastewater treatment plant disagreed about wastewater concentrations of total Kjeldahl nitrogen (TKN) and total suspended solids (TSS). Specimens were split and analyzed by both labs, and also by a commercial lab. The results are below. Give your interpretation of the situation.
