A current environmental concern is that of urban stormwater runoff, which can carry a multitude of contaminants and could threaten or impair surface waters. Pervious concrete (PC) is a type of concrete with significant void spaces that can facilitate infiltration and lead to less runoff. The EPA cites previous research to show that pervious pavement structures reduce such contaminants as metals and total suspended solids. Since Granular Activated Carbon (GAC) is a well-known contaminant adsorbent, the purpose of this research was to determine if PC with added GAC would result in improved runoff treatment, while still maintaining its material properties. …

The project described in our report looks at four alternatives to eliminate odor from the intersection of Las Vegas Blvd and Flamingo Rd: biofiltration, Granulated Activated Carbon (GAC) filtration, nitrate addition and the alternative of doing nothing. The odor is caused mainly by hydrogen sulfide, which escapes from the sewer system in this area. Each alternative was evaluated based on effectiveness, land usage, energy consumption, water and material usage, and cost. Cost was further broken down into initial costs and annual costs, and then a cash flow analysis was performed to evaluate the cost over a 30 year timeframe.
