I have a domestic well (not bore well) very near to my house in Kottayam district, Kerala. It is around 50 to 60 feet deep. Four years earlier it had water, currently water is not available when there is no rain. It is full of rocks at the bottom. My questions are:

1. If I dig further will there be the possibility of striking water ? To know this, will a scientific method wil help ? (a geophysicist or hydrologist) as in the case of borewells?

2. If yes, can the experts please suggest suitable contacts here in Kottayam?

3. Now the most importanr question: Since the well's bottom is rock, the conventional method to dig further is to remove the rock by explosives. But people say it should not be done because the house is very near to it. Is it true ? If yes please let me know is there any other method, by which I can remove the rock ? Is there any scieintific method available ?
