The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the overdraft and further degradation of the groundwater. To understand the response and behavior of the aquifer to different recharging and pumping scenarios, it is necessary to simulate the flow of groundwater in the unconfined aquifer. In addition, the movement of contaminants must also be simulated in order to understand the response of the aquifer to different waste application rates as well as recharging and pumping rates. The aquifer responses could then be used as constraints in a mathematical model that optimizes the recharging and pumping schedules. This scheme is applied to the Chino groundwater basin in southern California, and the results are presented and analyzed.
