what do we reckon the cheapest way to rigorously test clean, potable water is? Bottled, tap, well, stream, etc. I have a crap TDS tester, and i think i could figure out something with lasers and optical sensors.
Are gas chromatography mass spectrometers cheap enough, yet? anyone have one i can borrow?
