Shalllow wells are often contaminated with effluent from septic tanks, sewers, farm slurry spreading etc, which matter not at all for plants, which will relish the nutrients.
However it is rather unsavoury for say, salad veg and you may wish to stick to the company mains for them.
You can have a cheap test done to detect faecal bacteria and hence sewage or slurry contamination - your local EHO can probably arrange. Again faecal bacteria no big deal unless you are watering veg.
You can legally pump a suprising amount from your well - easily enough to water most domestic gardens - check with your local Environment Agency office.
For a clean supply you may need to sink a deeper borehole which is cost effective for very large gardens as shallow wells are apt to have slow rate of water infiltration or even run dry in prolonged droughts
To test your well hire a pump and pump the well dry measuring the amount of water pumped out (bucketfulls per minute - we are not talking rocket science here). Then time how long the well refills - if in minutes you have a very good well if days it is not so good.
