My first thoughts are as follows :

The water should be initially tested to find out what harmful levels of chemicals /other there may be. Micro-biological and chemical testing of drinking water quality should be performed to indicate whether water is safe to drink. These can then be treated appropriately with either dosing, filtration or other treatments as required. The water tank could be a good point for any dosing, however other solutions may be more appropriate such as ground tanks. (Commonly Chlorine with a contact time ie exposure time of the water to the chlorine, has been used to ensure germ free water delivery in UK).

Please be reminded that the water quality for sinks will be higher than toilets, if separate delivery methods can be accommodated (possibly a second untreated or less treated water tank and pipeline for the toilets in addition to a fully treated supply for the sinks etc). I appreciate the cost of this may render it inappropriate.

Ensuring the natural well is as well protected as it can be from contamination is very important, as is the training of a local well manager who maintains and ensures protection is not compromised. Such protection methods could be concrete casing around the top section of the well, a concrete lid with a outlet pipe for the water. All outlets should be protected so nothing can crawl or be dropped in the supply. Any ground around the well or outlets should be maintained to prevent any accidental contamination at point of delivery also.

Without knowing more about the spring location and type it is difficult to describe exactly what the set up should be ie. If the pump should be sat on top of the lid for easier maintenance or whether you could incorporate a filter bed within the well.

I will try to send you some information from our book 'Engineering in Emergencies' and section 3 of a document called WATER in emergencies, also an OXFAM document on spring protection. However if you could provide us some more information and any photos or topographical details you have we would be pleased to be able to answer your specific problem as accurately as we can rather than giving you general information on the topic.
