Indian ministry of Environment and Forestry has decided to launch in situ bio- remediation project in Buddha Nala in Ludhiana. This project will stop the industrial and domestic effluent discharge in the Buddha Nala.
The MoEF will try to create filters trough which untreated water will be passed. The effluent will be treated with microbial consortium. The treatment of effluent with microbial consortium will be helpful to reduce BOD “Bio – chemical oxygen demand” and COD “chemical oxygen demand”.
The MoEF is expecting to reduce BOD by 40% along with foul odor. In this project only microbes will be used and there will be no use of genetically modified organisms. Buddha Nala project is the largest bioremediation project of our country. The cost of the whole project will be funded by National River Conservation Directorate, Ministry of Environment and Forests, Government of India
use of microbes for the degradation of toxins and treatment of industrial effluent will work.

There are a number of cost/efficiency advantages to bacterial remediation, which can be employed in areas that are inaccessible without excavation. For example, hydrocarbon spills (specifically, petrol spills) or certain chlorinated solvents may contaminate groundwater, and introducing the appropriate electron acceptor or electron donor amendment, as appropriate, may significantly reduce contaminant concentrations after a long time allowing for acclimation. This is typically much less expensive than excavation followed by disposal elsewhere, incineration or other ex situ treatment strategies, and reduces or eliminates the need for "pump and treat", a practice common at sites where hydrocarbons have contaminated clean groundwater.
