Preliminary investigation of groundwater recharge by injection in Saskatchewan

Abstract

This research project was conducted to determine if it was feasible to improve the quality and quantity of water in an aquifer by artificial recharge through domestic wells. A portable water treatment system was designed and constructed to inject the best quality of water possible. A procedure that can be used to evaluate possible recharge sites was developed. The injection tests undertaken in this project indicated that the recharging of an aquifer through existing domestic wells is possible. The results of these injection tests were evaluated through pump tests and the chemical analyses of water samples. A computer program was developed to assist in the design and demonstration of the recharge process. The computer program was used to predict the piezometric head within the aquifer and to predict the mixing and gravitational segregation occurring within a confined, horizontal, radial flow system.
