That leads to the ocean!
Most floor finishes contain zinc, a metal that can damage the environment and sanitary sewer systems. Because of those reasons, the federal, state and county has set regulations for that metal.
The University of Hawaii Windward Community College reported that any wastewater containing zinc in excess of 2.6 mg/l should not be disposed of down the drain.
Banned wastewater should be stored in hazardous waste barrels, and disposed of by a licensed hazardous waste disposal firm.
To top that off, floor finish strippers typically contains many toxic substances including butoxyethanol, monoethanolamine, sodium hydroxide and/or sodium metasilicate.
Despite those clear hazards, I had seen a dingbat dump floor stripper and floor finish down a storm drain that leads to the ocean! That person should be disciplined for their incompetence!
Tip: You can help out Hawaii by reporting spills and environmental violations to the United States Environmental Protection Agency (EPA) on their website. They have a special box to report a person by their name!
