It has existed since the outset of the industrial revolution. Sewage treatment can be used to clean water tainted with industrial waste. Some examples of industrial waste are paints, sand paper, paper products, industrial by-products, metals,radioactive wastes,etc.
Penalties and fees are created as enforcement actions and to ensure that violating conditions are corrected in a timely manner to ensure consistent treatment of industrial dischargers; to eliminate economic advantages for violations; and to ensure that states recover expenses attributable to violations.
