Summary: In the course of field experiments designed to ascertain the main causes of pollution in shallow wells and the more important remedial measures which can be adopted, experimental renovations carried out on three shallow wells, all of poor hygienic quality, brought about a marked improvement in potability. The main items of renovation and construction concerned the use of correct waterproofing methods, and the sealing of the well orifice against surface seepage. Cemented concrete blocks and pre‐cast concrete cylinders provided adequate waterproofing for the first 10–14 ft. of the well shaft. Data obtained from a survey of 48 shallow wells in Northern Ireland sunk or renovated during the past two years, indicate the general ability of such wells to supply water of satisfactory quality, providing due care is taken in construction and siting to prevent the infiltration of surface water.
