I thank all persons who have responded to my query.  

 

Based on the responses, here is some more data:

1. The river is a perennial river (River Yamuna), fed from melting snow in the Himalayas and rain in its catchment.

2. The loacation is Agra, Uttar Pradesh, India

3. The water being drawn is further being filtered in a slow sand filter to obtain potable water.   There is no waste water being produced.  Regarding RWH, the location is open, with no buildings close by.  The ground is sandy and there is almost no runoff here unless very heavy rains occur for a long duration (which i have personally seen only twice in the past 25 years).

4. Quantity proposed to be drawn is 100 kilo liters per day, to be supplied to nearby villages.  (The facility will be activated soon)

5. Giving back to the community has a very high priority in the scheme of things at my organisation.  Tree plantation is done regularly on every possible occasion (Independence Day, Republic Day, Lorhi, Holi, Deepawali, ...)  Large swathes of barren areas have been covered with greenery over the years by sustained plantation and care.

6. The water level has been determined in two bores, near the river.  These levels are as follows:

RL at River bank - 100 m

RL at the bore on RBF site 250 m from river bank - 99.565 m

RL at a bore 500 m from river bank - 102.31 m

 7. Chemical analysis of water samples from these locations has not yet been done.  As suggested by Ian Pearson, I will try to analyse for chlorides and nitrates.

8. At present there are no bores between the river bank and the RBF bore.  I will have to put in bores for this purpose.  Will try out shortly.

9. The bore has already been drilled, but if required, another one at a more appropriate location can be made.  The existing one can be dismantled.

 

Again I thank all for your suggestions.  

Based on your suggestions, at present the option of drilling wells between the River and the RBF well and finding out the RL of water in these seems to a good way to proceed.  Further, Chloride and Nitrate estimation in the water from these wells could also provide an answer to my query.

 

If any further comments / suggestion can be made based on the above information, please do post the same for me.

Thank you.
