Brown, K. W. 1986. Hazardous waste disposal. What are the options? Grounds Maintenance 21 (2): 84, 86, 122.

Anyone who must dispose of more than 100 kg (200 pounds or approximately 30 gallons) of pesticide solution or rinse water each month is a hazardous waste generator, as the result of recent federal legislation. Such waste must be treated as a hazardous waste and must be stored and disposed of only by approved methods. Because many of the commonly used pesticides are on the EPA list of toxic substances, all surplus spray solutions, container rinsate water, spray equipment rinsate, solutions resulting from spill cleanup and misformulated solutions are hazardous wastes and must be dealt with accordingly. In the past, the common practice has been to wash the excess spray and rinse down the drain and into the sewer or allow it to run off into adjacent drainage ways. These practices will now likely be banned or abandoned because of the adverse impact on the environment when the pesticides flow or leach from such systems into surface or underground water resources.
