Two equal point sources discharge TC bacteria to an estuary as shown in the figure below. Assume salinity concentration of 8 ppt in the estuary. Note that 100% seawater has a salinity of 35 ppt.

a.     Determine the required percent removal in order that TC ≤ 2000/100ml. Assume equal removals at both plants and neglect wastewater flows (doesn't contribute to overall flow in estuary).

b.     Confirm (a) by plotting N vs X for the range of -3≤ X≥3.
