Dear All
Congratulations for the concern and efforts made towards ZLD (DTE, 16-31st May 2011). What is observed on the surface like: high TDS, change in Colour,smell, health hazards etc. are visible and can be assessed while doing EIA. What is the position of Groundwater? Any measure or idea about it? It is more challenging as it is invisible and not easy to map & control?
The modern tools like: hydrological and geophysical measure will help to map the polluted area both horizontally and vertically. Even these tools helps to map the source of pollution in case the same is not identified on the surface. On long term basis, these tools are tested and effective for regular evaluation and monitoring purpose.
Looking forward ....
