RE: Dirty Mop Water
Maybe mopping a bit less and targeted cleanups would help some. While we were putting together some information for auto repair shops, one of the shop owners I talked to said that they no longer mop their floors. Instead, they rely on sweeping and "squeegee-ing" up spills. You could try using a squeegee and a dustpan to "sweep" up the spill. Then, add the liquid to the
appropriate waste container. Just a thought.

Absorbents are sometimes used for small leaks. However, usually the spills

The mop water is sampled and ultimately dispositioned as hazardous or

through the recycling unit (Yellow Bellied Sump Sucker) because of the
bacteria that accumulates. The shop floor is mopped once a week and it
follows the same disposal process.
The coolant used is Trimsol E-190, the metal is mostly non-ferrous, and the
If anyone has any suggestions for applicable waste reduction techniques I'd
love to hear from you!
