I can remember asking myself this question many years ago at my first environmental laboratory job. I was manually shaking out separatory funnels for EPA 625 and 608 and each sample looked drastically different from the next as I was pouring them into each separatory funnel. At the time, I thought the term wastewater meant anything that came from a sewer pipe and that it mainly consisted of human waste. When I looked deeper into the possible sample categories for these methods, I was very surprised by the different sample types required to be tested as wastewater. With that, it prompted me to ask myself well where does it come from?
“Pesticides” is one of those terms that invokes a wide range of emotions in people. Some people smile when they think of the insecticides that keep their award-winning flower garden looking beautiful all season.
