Proper siting, location, construction and maintenance of your well will help to minimize the likelihood of contamination. The well cap should be checked regularly to ensure that it is securely in place and watertight. Joints, cracks and connections in the well casing should be sealed. Pumps and pipes should also be checked on a regular basis, and any changes in water quality should be investigated.
Surface drainage should be directed away from the well casing, and surface water should not collect near the well. The well itself should not be located downhill from any source of pollution.
Well water should be tested for bacteriological quality regularly and for chemical contamination if it is suspected. In addition to regular tests, well water should be tested immediately if there is any change in its clarity, colour, odour or taste, or if there has been a change in the surrounding land use. Through regular assessment and testing of drinking water, the microbial and chemical safety of your well water can be verified.
