Question

1. how do water agencies monitor the effectiveness of their filtration process?

a. alkalinity
b. conductivity
c. turbidity
d. ph

1. what is the disinfectant by-product caused by ozonation?

a. trihalomethanes
b. bromate
c. chlorite
d. no dbp formation

1. what is another term for haloacetic acids?

a. tthm
b. hocl
c. chlorite
d. haa5

1. what is the mcl for trihalomethanes?

a. .10 mg/l
b. .06 mg/l
c. .08 mg/l
d. .12 mg/l

1. what is the mcl for haloacetic acids?

a. 100 ppb
b. 60 ppb

Explanation:

1. Turbidity measures cloudiness from suspended particles, directly indicating filtration success at removing these particles.
2. Ozonation reacts with bromide in water to form bromate, a known disinfectant by-product.
3. HAA5 (five haloacetic acids) is the standard regulatory term for haloacetic acids in water testing.
4. The US EPA's Maximum Contaminant Level (MCL) for trihalomethanes is 0.08 mg/L.
5. The US EPA's MCL for haloacetic acids (HAA5) is 60 ppb.

Answer:

1. c. turbidity
2. b. bromate
3. d. HAA5
4. c. .08 mg/L
5. b. 60 ppb
