An ocean outfall diffuser that discharges treated wastewater into the Pacific ocean is 5,000 m from a public beach. The wastewater contains 105 coliform bacteria per milliliter (coliform /mL). The wastewater discharge flow rate is 0.3 m3/s. The coliform first-order death rate in seawater is approximately 0.3 h-1. The current carries the wastewater plume toward the beach at a rate of 0.5 m/s. The ocean current may be approximated as a pipe carrying 600 m3/s of seawater. Determine the coliform concentration at the beach. Assume that the current behaves as a plug-flow reactor and that the wastewater is completely mixed in the current at the discharge point.

An exposure assessment study was conducted in a nail salon. Previous studies have indicated that airborne concentrations of methyl methacrylate are approximately 1 ppm. If the LOD of the analytical method is 0.25 ug and sampling should be conducted at a flowrate of 0.01 LPM, what is the minimum amount of time the sample should be collected to achieve a detectable concentration? Note: Methyl Methacrylate MW=100.1 g/mol A. 11.2 Minutes B. 2.7 Minutes C. 8.5 Minutes D. 6.1 Minutes
