9. The food processing waste discharge causes an oxygen sag in a stream, with minimum DO of 2.0 mg/L. Upstream, the 10 °C water is saturated in O2 and has no BOD. Assuming the downstream oxygen deficit is proportional to the BOD, by what fraction should the BOD in the industry waste be reduced to have a healthy stream with DO > 5 mg / L?

Concentrations of toxaphene in fish may impair human health and fish-eating birds (such as bald eagles) that feed on the fish. What route of exposure is greatest for a higher-risk group that is assumed to consume 100 g fish per day? Assume the following correlation applies to toxaphene and our problem’s specific fish: log BCF = 0.85 * log Kow – 0.07

2. 1 Jar tests have indicated that 80 mg/L of alum are required to coagulate water for drinking water treatment. The source water contains 180 mg/L alkalinity as CaCO3 and 10 mg/L of suspended solids. The treatment plant capacity is 0.5 m³/s. How much alkalinity remains in the water after coagulation?
Poorly treated municipal wastewater is continuously discharged directly into a lake. The discharge from the wastewater plant into the lake occurs at a flow of Qd = 1 m3/hr. The concentration of phosphate (PO43, M = 95 g/mol) in the discharge flow (Cxd) that is decaying with first-order kinetics is 100 mg/L. The lake is a well-mixed water body of 100 m3. (Phosphate is naturally uptaken by algae with a first- order decay rate constant equal to 0.20/day.) The concentration of phosphate in the incoming river (Cx,r) is 10 mg P/L. The incoming river flow rate is Q, = 10 m3/hr. %3D a) Which of the following equations represent the correct mass balance equation?

A waste stream is discharging into a river at a rate of 5 m3/s. Upstream of where the waste stream enters the river, the river has a streamflow of 100 m3/s with a nitrate concentration of 1 mg/L. Downstream of where the waste stream enters, the nitrate concentration has been measured to be 3 mg/L. What is the nitrate concentration in the waste stream? Assume no change in storage in the system.

A wetland with a volume of 103m3 drains into pond with a volume of 106 m3. The concentration methylmercury (CH3Hg) in the wetland is 4 × 10-3 ng/L. The wetland is flowing into the pond at a rate of 103 m3 /day. Microbial processes are causing methylmercury to be generated within the pond at a rate of 100 ng/day. The pond has a concentration of 6 × 10-4 ng/L CH3 Methylmercury decays within the pond at a rate of 100 ng/day. The pond has an outflow of 103 m3/day. Is methylmercury mass increasing or decreasing in the pond? Show all mass balance calculations?
