Using the RCRA hazardous waste lists, determine whether the following are hazardous wastes using the RCRA listing procedure. If it is a listed waste, state the waste number. If is is not a hazardous waste, state why not. Assume that the industry producing the waste is a RCRA hazardous waste generator. 1. 2800 kg per month of acetone waste generated as the result of metal parts washing. 2. 5.7 million L/day of 150 mg/L trichloroethylene in an industrial waste stream being discharged to a municipal wastewater treatment plant. 3. 235 kg of endrin that is being disposed of because it is off-specification and out of date.

Collection Systems

The collection systems form a part of sanitary engineering, which is a sub-branch of civil engineering. It is also known as public health engineering and wastewater engineering. It is a methodology followed to remove and properly dispose of human waste, along with creating systems to provide safe and clean usable water. These measures ensure a hygienic and disease-free community. Sanitary engineering, apart from building sewer disposal units, is also involved in plumbing, fire protection, hydraulics, life safety, environmental protection, information technology, microbiology, pathology, and so on.
