If you believe that someone has disposed what you believe is hazardous waste in an inappropriate location, stay away from it! Call your local city police department. Dumping hazardous waste in an inappropriate location is a crime, and the Police Department or other regulatory agency may need to collect evidence.
Street or storm drain dumping: If the substance is a highly flammable liquid such as gasoline or paint thinner, call 911 immediately! A serious explosion could occur. Otherwise, contact your local police or sheriff. It is forbidden by law to drain anything into the storm drain or gutter except rainwater and the occasional sprinkler runoff. Dumping of soapy water from carpet cleaners and steam cleaning residues from parking lot cleaning is prohibited. Bright green or yellow liquids may be automobile antifreeze, which has a sweet taste and is very toxic to animals, so do not delay in reporting it if you see it standing or being drained into the gutter. Animals (and people) can suffer a slow, painful death due to liver and kidney failure after drinking antifreeze. Dumping oil into the stormdrain may also cause harm to a stream, river or ocean.
