Acting on a tip, two inspectors from the Environmental Protection Agency (EPA) took samples of the wastewater discharged from a paper mill by accessing sewer pipes through a manhole located on the edge of company property 300 feet from where the water dumped into the public sewer system. The mill and its owner were indicted on criminal environmental law charges based, in part, on the test results from those samples. Are the test results admissible at trial? [Riverdale Mills Corp. v. Pimpare, 392 F.3d 55 (1st Cir. 2004).]
