The audit report on the economic sector for 2015-16 laid out in the Uttar Pradesh Assembly said the malfunctioning of existing treatment facilities was also responsible for the poor quality of water.
The UP Pollution Control Board (UPPCB) failed to take appropriate action against the defaulters like municipal authorities and industries, the report said.
UPPCB monitors the pollution level in rivers and water bodies of the state by collecting samples once every month and the audit analysed the reports of 12 major rivers and six water bodies.
The BOD (bio-chemical oxygen demand) level and total coliform (which included bacteria that are found in the soil in water that has been influenced by surface water and in human or animal waste) are above the prescribed standard in 12 major rivers and six water bodies for the years 2013-15, the report said.
The water quality of Gomti was also not within the prescribed standards and the main reason for pollution in the river was sewage generation in Lucknow being much higher than the total capacity of the two STPs (sewage treatment plants), the report pointed out.
