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.

Laboratory Determination of Hydraulic Conductivity

Hydraulic conductivity is the measure of flowability of water inside the soil in the presence of a hydraulic gradient. The hydraulic gradient is defined as the difference in the water heads in the soil, which induces a water motion. In simple terms, a hydraulic gradient is the presence of a potential that induces a flow of water.
