Respected Lalooji. The land near railway tracks in Mumbai Suburbs is given on lease basis or rent basis to citizens for cultivating vegetables. All these people are using waste water which is also contaminated with industrial waste water which contains hazardous elements which are harmful to human bodies. This practice of using waste harmful water should be discontinued immediately . If the same cultivation is to be continued then they should be directed to use fresh water and also the Railway Authorities should keep check so that they are not using harmful water for cultivation.
