Question

Calculate the number of wells that can be used to pump and treat a plume with capture width far upstream of 150m, assume that the hydraulic conductivity of the site is 0.05 cm/s, the aquifer is confined with a depth of 4 m, the storage coefficient is 10-4 and the regional groundwater gradient is 0.015. Assume well radius=0.1 m, the maximum permissible drawdown =5 m after 1 year since pumping began. Use the javendel et al's approach. The no. Of wells to be used are:
