Problem 1. A drilling operation punctured a discarded bottle of a pesticide, suddenly releasing a small volume of the liquid into the aquifer. Groundwater flow in the region is restricted to a shallow, sandy aquifer that is about 3-m thick. The organic matter content of the sand is negligible, so the pesticide does not adsorb onto the soil. A water supply well is located 200-m away from the point of release in the direction of the groundwater flow. Use the parameter values given in the following table to address the questions below. 1. Create a figure showing the concentration (g/L) as a function of time at the supply well. Based on that figure, approximately how many days after the concentration first reached 10g/L did it return to that level? 2. Calculate the maximum concentration (g/L) at the supply well. 3. How many days after the release will that maximum value occur? Problem 1.
