To complete secondary treatment, effluent from the sedimentation tank is usually disinfected with chlorine before being discharged into receiving waters. Chlorine is fed into the water to kill pathogenic bacteria, and to reduce odor. Done properly, chlorination will kill more than 99 percent of the harmful bacteria in an effluent.

Since different fish have varying tolerances to dissolved oxygen levels, the wastewater being discharged from an aquaculture operation may have large impacts outside the facility long before a problem is detected within. Anti-fouling agents used to keep cages/pens clean are highly toxic.

Introduction A large volume of ,wastewater, continues to be ,discharged, into natural watercourses leading to pollution of the coastal zones and drinking water reservoirs in India [1]. Disposal of partially treated and mostly untreated effluents into rivers and lakes and runoff from urban and agricultural areas are the two main reasons responsible for deterioration of drinking water resources [4].

Locations where such unplanned groundwater recharge has occurred include Egypt, Mexico, Peru, and Thailand. In Mexico, a large flow of ,wastewater, from Mexico City is ,discharged, to the arid Tula Valley (also known as the Mezquital Valley) where a total of 500,000 inhabitants are supplied water this way (Jimenez and Asano, 2008).

Washington fish farmers are required to ,keep, the total organic carbon in the sediments surrounding cages within a certain level, which is indexed to sediment grain size. If this standard is exceeded, the farmer is required to sample the benthic animals, a much more expensive and time-consuming affair.
