4. At a site owned by Company X, it is decided to remediate a plume using a double trench system as shown below. A plume lies between the two trenches in a sand layer that is capped by a relatively impermeable clay layer. Nutrient and oxygen laden water will be injected in the trench on the right The water will flush from right to left and be pumped out of the left trench. To ensure maximum biodegradation, it is best if the sand layer stays saturated. Thus, the trench on the left will be pumped just enough to keep the sand layer saturated. The trench on the right will be kept as full as possible. For the sand layer, assume than n-0.35 and k 10.2 cm/s. a) For a one meter thick slice of the sand layer, how much water would need to be pumped to flush through one pore volume* b) How long would it take (in days) to pump five pore volumes of water through the sand? 30 m 1.7 m Clay 3.2 m Bedrock A pore volume is a common term used in analysis of site remediation projects involving flushing. A pore volume is defined as the total volume of the voids in the region being flushed. So when you flush five pore volumes it means that you have flushed enough water to displace all the water in the voids five times. To find the pore volume, calculate the total volume of the region being flushed and multiply by the porosity.
