Abstract:
Installed STPs are not operated well and there is large quantity of sewage from drains and STPs being disposed into main stem of River Ganga. Thickly populated settlement area of Rishikesh to Anupsahar has selected as study area and focused on assessment of pollution load of various drains and STPs into main stem of River Ganga during pre-monsoon of 2015. Eighteen for drains, 9 for raw and 9 for treated sewage for STPs grab samples were collected and pH, EC, TSS, TDS, Cl-, COD, BOD, NH3-N, TC and FC analysis was done at the CPCB laboratories. Bagad River belong to ‘brackish’ water category. Except Sarai, remaining STPs have lacks of infrastructure and capacity. BOD/COD 50 % of the drains and 67% of the STPs treated less than 0.3 mg/l and also the discharge does not meet the CPCB proposed standards through biological treatment and increasing of BOD loads in these drains indicates the negligence of maintenance to control the pollution in their particular locations.
