Q. We frequently use 55-gal drums of Liquinox to remediate gasoline contaminated soil and groundwater. We are not cleaning lab glassware. We inject it into the groundwater at hazardous waste sites to solubilize the globules of gasoline or other contaminants trapped in the porous spaces of the soil. I would like to know if it is cheaper to buy the powdered Alconox and dissolve it? Is there an equivalent unit of measure to evaluate the two?

Read the answer.

Alconox will supply a Liquinox pump dispenser that meters out 1 ounce of liquid detergent at a time. Request yours.

We applaud you for looking to employ sustainable, safe, clean, and reduced waste cleaning processes. The first step in evaluating the environmental health and safety of an aqueous cleaner is to secure the material safety data sheet and technical bulletins for the cleaners you plan to test or use, and to assemble as much information as you can about the soils you will be removing. A review of this information should disclose important environmental and health hazards as well as regulations.
