One of the first things that a newbie in environmental consulting does is go out and sample ground water monitoring wells . Doesn't matter if you're a biologist, geologist, engineer... most environmental investigations and practically all remedies involve groundwater monitoring, and the work doesn't involve a whole lot of technical know-how and has minimal chance for personal injury. That last bit, of course is relative to all fieldwork - any time you work outside, you have a decent chance of getting into some sort of vehicle incident, getting bitten by something, throwing your back out hoisting a cooler, and getting chased by angry property owners.
