EC238 Study Guide - Final Guide: Total Maximum Daily Load, Biochemical Oxygen Demand, Criteria Air Contaminants
Document Summary
Organic wastes: degradable wastes such as domestic sewage. Inorganic substances: chemicals such as toxic metals salts, and acids. Technology-based standards in ontario: municipal & industrial strategy for abatement (misa) Ontario initiated a program to deal with all types of water pollution: conventional discharges, toxics, metals, and organic chemicals. The goal of misa was the virtual elimination of toxic contaminants in municipal and industrial discharges into waterways . A technology-based effluent standard is an effluent standard set at the level of emissions that a source would produce if it were employing a particular type of abatement technology. Point source a pollutant with a well-defined point of discharge into the environment; for example, air pollutants from the stacks of electricity-generating plants or other industries. Nonpoint source a pollutant that does not have a well-defined source or discharge. An example is runoff of agricultural wastes or pesticides into rivers or groundwater.
