JLI Environmental Labs, Auburn NY

JLI is hard to find, but their assistance is invaluable. To get there, turn in at the Adventure Zone, drive past it and across the parking lot for the leather crafting shop. The office is in the low white building with the blue door. If they're supposed to be open, try the door - it's likely open.
We needed to test our well water twice, and both times their instructions were clear, succinct and helpful. We got our results in about two weeks and were able to treat the water with their guidance.
