d. rain gardens help filter out pollutants.
3.) Which of the following are not true of stormwater runoff?
a. as it washes across impervious surfaces, stormwater carries oil, herbicides, pesticides, heavy metals, pet wastes and other contaminants into the waterways.
b. it contributes to erosion.
c. It causes changes to the chemistry and temperature of a stream.
d. It goes to a treatment plant before it is discharged into a waterway.
e. It is discharged directly into waterways without going through a treatment facility.
4. Which of the following does not contribute to the restoration and protection of our waters?

d. they are highly significant and contribute greatly to the health of the entire watershed.
6.) It is essential that we protect, restore and conserve our water resource because:

b. with an increasing human population demands for this limited resource are growing
c. it is the responsible thing to do
7.) Actions individuals can take as responsible stewards of our water resource are:

d. mowed and manicured open space
e. rain gardens
f. grassy swales along streets
9.) True or False—the greatest threat to water quality is human activities.
