The water in Fell city also contains 30 μg/L of chloroform (formed in the water treatment plant), 5 μg/L of chlorpyriphos (a persticide), and 10 μg/L of chromium VI. Given the reference doses below, calculate the total hazard quotient. State which compound is the total HQ is acceptable. References doses (all mg/kg.d): 0.01 for chloroform, 0.0003 for chlorpyiphos, and 0.003 for chromium VI. Answer: 0.66
Suppose you have a soil that is made up of 10% organic matter with CEC = 200 cmol/kg, 40% kaolinitewith CEC = 10 cmol/kg, and 50% vermiculite with CEC = 100 cmol/kg.1- Calculate the overall CEC of the soil by taking a weighted average of the three soil components.2- What percentage of the overall CEC is contributed by the organic matter? How does that numbercompare to the 10% of the soil itself that is organic?

Q) Calculate the “Chlorine Demand of Water”, if “addition of (i.e. Chlorine added)” 200 kg/d of chlorine in a flow of 0.088 m3/sec gives a ‘residual of 0.20 mg/l as Chlorine (Cl2).
A 1.000-gram sample of NaOH (39.997 g/mol) which has been exposed to the air for some time (NaOH will adsorb water and CO2 from the ambient air) is dissolved in water and then diluted to 500.00 mL. 100.0 mL of this solution required 38.60 mL of 0.1062 M HCl to be titrated to the endpoint (~pH 3). A second 100.00 mL portion is treated with excess BaCl2 and then diluted to 250 mL and filtered. 200 mL of the filtrate required 29.62 mL of HCl to titrate to the (~pH 8-9) endpoint. Calculate the mass percentage of NaOH and Na2CO3 (105.9898 g/mol) in the original sample. The adsorbed CO2 is converted to Na2CO3. The Ksp for BaCO3 (s) is 2.58 x 10-9.
