Spilfyter

This is a cool product I used to use when I was a state hazardous waste inspector. Back then they were made by an outfit called J.V. Manufacturing; now they’re sold by the NPS Corporation, but same thing. I used the Chemical Classifier Strips, which have little square cutouts which change color for various contaminants. You can tie a little string on one and fan it in the vapor space of, say, a half-full drum, look for color changes, and then dip it into the liquid. there’s a color chart to compare it to for results. Very useful for “quick & dirty” field testing. They also make one for wastewater.
