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 ...
Effluent limits – limits used to control discharges through technology-based or water quality-based standards; Monitoring and reporting requirements – used to determine permit compliance; Special conditions – can be used to supplement effluent limits; Standard conditions – pre-established conditions that apply to all NPDES permits.
[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.
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]

Continuous emission monitoring systems (CEMS) are used as a tool to monitor the effluent gas streams resulting from combustion in industrial processes. CEMS can measure flue gas for oxygen , carbon monoxide and carbon dioxide to provide information for combustion control in industrial settings.
The Central Pollution Control Board (CPCB) reported that as of 2016, there were 746 industries directly depositing wastewater into the Ganga, which is the largest river in India. This wastewater contains heavy metals such as lead , cadmium , copper , chromium , zinc , and arsenic , which negatively affect both aquatic life as well as human health.
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.
