Borehole water is the only source of reliable potable water to this environment. However, sampling of the water quality has shown contamination. Perhaps as a result of soil porosity enhancing salt water intrusion, inter aquifer exchange, and sometimes iron loadings from upper region being deposited by river flows. Presently, there is no engineered landfill, and so all the municipal solid wastes are dumped in open pits. This also enhances leachates transfer to ground water levels. With all these complexities it becomes difficult to choose optimum aquifer for potable water extraction. Please advise the method to adopt.
evaluate the fresh ground water resources in coastal and delta areas are very much valuable but quite difficult task. We have carried out geophysical and geochemical investigations in Godavari and Krishna delta of southern part of India. Our work was considered as encouraging and useful. Results are well published.
Dear Virendra, kindly provide a link to some of your published work.
If ground water contaminated you have a problem restoring it. Better make a difference between drinking water ± 1 lit person per day, may be 1,5 in hot climates. This water can be treatd at point of use. The remaining water can be used as is for various purposes as is. Simple carbon filters (biochar) can be used for treating the drinking water. Those are commercially available and can be produced locally at very low costs.
