You must have collected nearly 100 samples, all different matrices (water, soil, sediment, product samples), and multiple analyses are needed. You have COCs (chain of custody forms) filled out for everything, and you are driving over to the laboratory…

Periods immediately after a rainfall have to be avoided.” Temporal and seasonal changes can play a…

Because of this variability in the ‘show’ers, the standard test may not capture the event appropriately. As prefaced in last week’s post, your data shows periodic flow and no buildup pressure. The…
