[2] Since the mid-1970s, EPA has promulgated ELGs for 59 industrial categories, with over 450 subcategories. Effluent Guidelines currently control pollution at approximately 40,000 facilities that discharge directly to the nation's waters, 129,000 facilities that discharge to POTWs, and construction sites.
[1] [2] ZLD technologies help industrial facilities meet discharge and water reuse requirements, enabling them to meet government discharge regulations, reach higher water recovery (%), and treat and recover valuable materials from the wastewater streams such as potassium sulfate , caustic soda , sodium sulfate , lithium , and gypsum .
A Discharge Monitoring Report (DMR) is a United States regulatory term for a periodic water pollution report prepared by industries, municipalities and other facilities discharging to surface waters. [ 1 ] : 8–14 The facilities collect wastewater samples, conduct chemical and/or biological tests of the samples, and submit reports to a state ...
Beginning in the 20th century, designers of industrial and municipal sewage pollution controls typically utilized engineered systems (e.g. filters, clarifiers, biological reactors) to provide the central components of pollution control systems, and used the term "BMPs" to describe the supporting functions for these systems, such as operator training and equipment maintenance.
Delhi Pollution Control Committee was established in 1991 by central government and works with Central Pollution Control Board and National Green Tribunal to control the pollution in the capital.

In addition to wastewater discharge monitoring, EPA works with federal, state and local environmental agencies to conduct ambient water monitoring programs in water bodies nationwide. [23] The CWA requires EPA and the states to prepare reports to Congress on the condition of the nation's waters. [24]
