A river is contaminated with 0.65 mg/L of dichloroethylene (C2H2Cl2). What is the concentration (in ng/L) of dichloroethylene at 21 C in the air breathed by a person swimming in the river (kH for C2H2Cl2 in water is 0.033 mol/L * atm)

(7) The following values were obtained for the nitrate concentration (mg/L) in a sample of river water: 0.403, 0.410, 0.401, and 0.380. The last measurement is suspect. Based on this data set only, should it be rejected? Justify your answer. (8) Three further measurements were added to those given in question (7) so that the complete results became: 0.403, 0.410, 0.401, 0.380, 0.400, 0.413, and 0.411. Should “0.380” still be retained/rejected? Justify your answer. (9) Based on questions (7) and...

You are the lead engineer at a bioremediation field site that is contaminated with 330 mg/L PCE, which has a molecular formula of C2Cl4. The other available electron acceptors are: oxygen at 8 mg/L, nitrate (NO3-) at 600 mg/L, Fe(OH)3 at 600 mmol/L, and sulfate (SO42-) at 250 mg/L. When these are reduced they become: water, NH4+, Fe2+, and S2-, respectively. PCE must be reduced completely to ethene (C2H4) or the local community group will protest. However, all of the...

An industrial wastewater flowing at a rate of 37,000 m3/day is contaminated by 187 mg/L of propanol – CH3CH2CH2OH. As an environmental consultant, you propose to treat the water in an activated sludge process in which propanol is oxidized by oxygen into carbon dioxide – CO2. The reaction is highly favorable and assumed to be complete. a) Equilibrate the half-reactions and overall reaction that are expected to occur during the treatment process. b)Determine the theoretical quantity of oxygen (in mol/day)...
