2. How important do you think wastewater from
manufacturing plants is as a source of water pollution? a. Very
Important b. Important c. Not Important |
| Since the passage of the Clean
Water Act in 1972 (and subsequent legislation) industrial
discharges have been regulated by state and federal governments. As a result,
wastewater from manufacturing plants plays a relatively minor role in
water pollution in the U.S. In our region, manufacturing is a minor part of the economy, which also
minimizes the role of manufacturing in local pollution discharges. |
3. How important do you think wastewater from
sewage treatment plants is as a source of water pollution? a. Very
Important b. Important c. Not Important |
| Wastewater from sewage
treatment plants is regulated by state and federal governments. The plants are
not permitted to release more than a certain amount of nutrients
(phosphorous and nitrogen), bacteria and total suspended solids. For
example, the Moore's Creek Waste Water Treatment plant is permitted to
discharge 2,756 pounds of total suspended solids a day into Moore's Creek,
but in fact, the plant typically discharges 481 pounds a day. Sewage treatment
plants do contribute to water pollution, but in regulated amounts that are
being reduced as plants upgrade in response to more stringent federal
regulations. |

4. How important do you think pollutants that wash
out of the air, such as acid rain, are as a source of water pollution?
a. Very Important b. Important c. Not Important
|
| Acid rain has caused
significant damage to trees and aquatic systems on the Blue Ridge, and in the Shenandoah National Park
in particular, but is not a
significant source of water pollution in the Charlottesville/Albemarle
area. Some studies have pointed to rain as a significant source of the
nutrient nitrogen, which can cause algae blooms. |
5. How important do you think rainfall runoff from
yards, parking lots, and streets is as a source of water pollution? a.
Very Important b. Important c. Not Important |
| Rainfall runoff from yards,
parking lots and streets can be very important source of
pollutants such as sediment, nutrients, bacteria, road salt, oil and gas
residue, as well as heavy metals associated with automobile tires and
brake linings.
In addition, summertime runoff from parking lots can cause a rapid spike
in stream water temperatures. |
6. How important do you think rainfall runoff from farms
and agricultural operations is as a source of water pollution? a. Very
Important b. Important c. Not Important |
| Agricultural runoff can be a
very important source of pollutants
such as sediment, nutrients and bacteria, as well as herbicides and
pesticides if farmers do not use agricultural Best Management Practices
(BMPs) to protect streams on their
property. |
7. How important do you think dirt eroding from
construction sites is as a source of water pollution? a. Very Important
b. Important c. Not Important |
| Construction activity is
regulated by the state and each locality. Developers are required to
install Best Management Practices (BMPs) such as silt fences and sediment
basins to limit the amount of eroded soil that reaches local bodies of
water, and hold soil in place with a cover of grass or other vegetation
once earth-moving has been completed. Nevertheless, such controls are not
very efficient, and localities are hard pressed to adequately monitor
construction activity. As a result, construction sites are probably an
important source of water pollution. |
8. How important do you think trash that gets
dumped into lakes and rivers by boaters and other recreational users is as
a source of water pollution? a. Very Important b. Important
c. Not Important |
| Paper and plastic trash is
probably a greater esthetic concern than a threat to water quality. Such
trash can, however, interfere with the functioning of stormwater management
facility outlets and inlets. In addition, some litter, such as cigarette butts, can harm wildlife that mistake
it for food. |
9. Out of all of the sources of water pollution
that you were just asked about, which one do you think is the most
important as a source of water pollution in our area? That is, which
one contributes the most to water pollution. a. Wastewater from
manufacturing plants b. Wastewater from sewage treatment plants c.
Pollutants that wash out of the air, such as acid rain d. Rainfall
runoff from yards, parking lots, and streets d. Rainfall runoff from
farms and agricultural operations e. Dirt eroding from construction
sites f. Trash that gets dumped into lakes and rivers by boaters and
other recreational users |
| Rainfall runoff ("d") is
probably the biggest source of water pollution in urban areas such as
Charlottesville and Albemarle County's growth areas, and agricultural runoff is probably the
most important source of water pollution in rural areas. |
10. When you mow your grass, what do you do with
the grass clippings? Do you a. Leave them in the yard b. Collect
them and throw them in the garbage c. Rake or blow them into a drain
d. Mulch or compost them |
| It is best to leave grass
clippings in the yard or compost them because this returns nutrients to
the soil without the use of additional fertilizer. Disposing of them in the
garbage will also prevent water pollution. Dumping them down a storm drain will
pollute a local body of water with decaying organic matter. |
11. Approximately how often you use fertilizer on
your lawn? Would you say a. Monthly b. Two or three times a year
c. Once a year or less
12. If you fertilize, does anyone ever test
the soil in your lawn to determine how much fertilizer is needed? a.
Yes b. No |
| It is best to fertilize a lawn
once a year, in the fall. This encourages healthy root growth and
minimizes the likelihood that fertilizer will be washed into storm drains and
streams by rain. More importantly, a soil test helps insure that excess fertilizer will not be
applied at any time, saving money and decreasing the possibility of water pollution.
Fertilizer (nutrients) in water causes algae blooms that kill fish and
other creatures by depleting oxygen levels. Call your local Virginia Cooperative Extension office for
information about an inexpensive soil test. |
13. Do you wash your vehicle at home, or do you
take it to a car wash? a. At home b. Take to a car wash c. Both
at home and take to a car wash d. Do not wash car |
| If you take your car to a car
wash that recycles water, you will conserve water and keep detergents and
wastewater out of streams. If you wash your car at home, do it on the
grass where wastewater will not go down a storm drain and
wash water can be filtered through the soil. Use a nozzle
on your hose with an automatic shut-off and a bucket
to save water.
Use biodegradable detergents. |
14. If you change your oil at home, how do you
dispose of the used oil? Do you dispose of it a. In a designated lawn
area b. With other garbage (dumpster, placed in trash bags with other
trash, etc c. Pour it down a storm drain d. Take it somewhere it can
be recycled (recycle center, gas station) |
| One quart of motor oil can
pollute one million gallons of clean water. That's what happens if you
dump it down a storm drain. Oil dumped in the woods or on the lawn it can
pollute ground water. Please take your used motor oil to be properly
recycled.
Many places that sell oil also recycle it free. Check
with you local auto parts supplier |
15. When you walk your pet, how often do you pick
up their droppings? a. Always b. Often c. Sometimes d. Rarely
e. Never |
| Pet waste pollutes water with
bacteria and nutrients (causing algae blooms) when rain runoff carries it
to storm drains or streams.Several of our streams in the Rivanna River watershed are impaired by excessive
levels of bacteria. |
16. If you had to pick one of the following options
for where stormwater runoff goes once it enters a storm drain, would it be
that it goes to a. The sewage treatment plant b. A separate
special sewer treatment plant c. Nearby fields and yards d. Closest
river, stream or lake e. Drainage pond |
| The runoff that goes down a
storm drain usually flows untreated into the closest river, stream or lake.
However, some storm drains empty into a stormwater management facility
such as a rain garden or a detention pond where some pollutants will be
filtered through the soil beneath the basin.
However, none of the runoff in the Rivanna River watershed goes to a
treatment plant. |
