Central Pollution Control Board (CPCB)

Rivers are one of the prime suppliers of drinking water. They are also important for agriculture, fisheries and recreational activities. However some of these activities also pollute the rivers. Pollution can be either from point sources such as industrial or sewage effluent discharges, or can be diffused from roads or agricultural run-off. Therefore it is necessary that rivers are protected from pollution and are managed as a sustainable resource for all of the activities that depend on their water quality.

Against this backdrop, this document by the Central Pollution Control Board (CPCB) elaborates on the river water quality in India. The Central and State Pollution Control Boards / Pollution Control Committees in Union-Territories of India are responsible for restoration and maintenance of the wholesomeness of aquatic resources. To ensure that the water quality is being maintained or restored at desired level it is important that the pollution control boards regularly monitor the water quality. The water quality monitoring is performed with following objectives:

The report presents the results of a detailed survey of groundwater quality in metropolitan areas (population >100,000) in India.

The report recognises that most groundwater quality problems are anthropogenic in origin, caused by a combination of over-exploitation and infiltration of wastes. Inadequate infrastructure and resources mean that waste generated by cities and industrial areas is not properly collected, treated and disposed, thus leading to grondwater contamination.

The guidelines summarize policies and action plan for water quality management and consider designing a water quality monitoring network

The documents titled 'Guidelines for water quality management' and 'Guidelines for water quality monitoring' are published by the Central Pollution Control Board (CPCB) in 2008, under the guidance of the Water Quality Assessment Authority formed under the Ministry of Environment and Forests (MoEF).

The reports help in evaluating the nature and extent of pollution control required, effectiveness of exisiting measures, in drawing water quality trends and prioritising pollution control efforts
This post presents reports on  the status of water quality in India  by the Central Pollution Control Board, Ministry of Environment and Forests  for the years 2007, 2008 and 2009. These reports present the outputs of water quality monitoring done under the project on Monitoring of Indian Aquatic Resources (MINARS).

The water quality data for the years 2002-2008 has been analysed here.

This brief report by the Central Pollution Control Board (CPCB) presents an analysis of the monitoring of the water quality in India under the National Water Quality Monitoring Programme. The water quality data for the years 2002-2008 has been analysed and monitoring locations exceeding the water quality criteria have been identified as polluted locations with respect to risk.

It is expected that the development and proper use of such a manual by concerned laboratories will bring homogeneity for ensuring quality assurance especially in water and wastewater analysis.

WastewaterThis guide manual on water and wastewater analysis prepared by the Central Pollution Control Board (CPCB), caters to the need of evolving a simplified code of practice for the laboratories engaged in carrying out water quality assessment under the Hydrology Project-II implemented by the

Water quality of the Ganga as it passes through various states is presented in this document.

The data has been collected over a period of many years from 39 water quality monitoring stations along the main river and 102 stations on its tributaries which were setup in 2008/09.

The study focuses on the parameters for dissolved oxygen, (DO), biochemical oxygen demand (BOD) and faecal coliforms (FC) as these indicate the biological health of the river. The period of study for the river Ganga is 1999-2008. The study finds that most of the water quality parameters studied do not meet the standards.

CPCB's comprehensive environmental assessment of industrial clusters finds only 16% spots with normal pollution levels. Ankleshwar in Gujarat is the worst, while Digboi in Assam is the best.

CPCB ReportA Comprehensive Environmental Pollution Index (CEPI) is a very useful tool to capture the health dimensions of the environment including air, water and land. The CEPI is intended to act as an early warning tool and can help in categorising the industrial clusters/areas in terms of priority of planning needs for interventions.

This report by the Central Pollution and Control Board (CPCB) presents the results of the application of the CEPI to selected industrial clusters or areas.

The main objective of the study was to identify polluted industrial clusters or areas in order to take concerted action and to centrally monitor them at the national level. This was in order to improve the current status of environmental components such as air and water quality data, ecological damage, and visual environmental conditions.

This is the fourth in a decadal series of reports published by the Central Pollution Control Board (CPCB), which provides basic information about the status of water supply and sewage generation.

CPCBThis is the fourth in a decadal series of reports published by the Central Pollution Control Board (CPCB), previous ones published in 1978-79, 1989-90 and 2000, which provides basic information about the status of water supply and sewage generation and treatment of 498 Class-I cities and 410 Class-II towns, along with information on 53 coastal Class-I cities and 35 coastal Class-I towns, besides Ganga Basin as a separate subsection.
