ENVIRONMENTAL ENGINEERING (Practice Questions) a). List the three categories of use that account for most of the wells constructed, and identify the characteristics that are common to all wells. b). Consider a contaminant plume that is 100m wide x 40m thick x 1200m long. If d’Arcy’s velocity is 2.0 x 10-6 m/s and the aquifer porosity is 0.4, what minimum pumping rate would assure full plume capture, and how far apart should two wells be placed for optimal location / alignment along the leading edge of the plume? C). How long would it take to pump an amount of water equal to the volume of the water contained in the plume? State any assumptions made.
