Clean Water Act
Environmental Protection Agency
Phase I 1990 – large municipal systems
Phase II 1999 – additional municipal systems
2004 National Water Quality Inventory
Of assessed U.S. water bodies, 44% of rivers (miles), 64%
of lakes (acres), and 30% of bays and estuaries (sq. mi.) are
impaired by pollution.
Do not meet water quality standards
Not clean enough for swimming and fishing
Leading sources include atmospheric deposition,
agriculture runoff, and hydrologic modifications.

What is it?
Storm water is water from rain or melting
snow that does not soak into the ground.
It flows from rooftops, over paved areas and
bare soil, and through sloped lawns.
4
Pollutants
5
Runoff collects and
transports soil, pet
manure, salt, pesticides,
fertilizer, oil and grease,
leaves, litter and other
potential pollutants.
Yard Waste/Fertilizer
6
Sometimes we dump or sweep pollutants down the
drain.
We also spread lawn chemicals that end up in the
street, and subsequently into storm drains.
Washing the car
7
Rinse water, as well as grease and oil, from washing
your car drains to the curb then to the storm sewer.
Scoop the poop!
8
Pet droppings contain
bacteria and other
pathogens.
When our pets leave
those little surprises,
rain washes all that
waste into our storm
drains.
Hazardous Waste
Paint, pesticides, used motor oil, solvents, etc.
At EVMS, dispose via Environmental Health & Safety
(EH&S)

Where does it go?
Rain carries pollutants
to streams, wetlands,
lakes and coastal
waters.
Storm drains carry
runoff from a
neighborhood to the
nearest body of water.
12
Storm sewers DO NOT carry storm water to wastewater
treatment plants!
Why the concern?
13
Excess nutrients cause
algae blooms.
When algae die, they
remove oxygen from
the water.
Fish and other aquatic
life cannot exist in
water with low oxygen
levels.
Bacteria can wash into
swimming areas and
create health hazards,
often making beach
closures necessary.
Algae
Why the concern?
14
Household hazardous
wastes like insecticides,
pesticides, paint,
solvents, used motor oil,
and other auto fluids can
poison aquatic life.
Debris – plastic bags, sixpack rings, bottles, and
cigarette butts – washed
into water bodies can
choke, suffocate, or
disable aquatic life.
Illicit Discharges
15
An illegal and/or
improper waste
discharge into a storm
drain system and
receiving waters
Example: connection of
a floor drain in a
business to a storm
sewer
Illicit Discharges
16
Pouring used motor oil
down a storm sewer
catch basin rather than
properly recycling the
waste oil.
One quart of used motor
oil can contaminate
250,000 gallons of
drinking water and
spread an oil slick the size
of two football fields.
Oil Spill?
Exxon Valdez oil spill –
1989
17
11 million gallons of oil
spilled
Do-it-yourselfers
Home oil change
200 million gallons per
year
Impacts
Flooding
Clogged
drainage ditches in neighborhoods
Beaches closed due to contamination
Hampton,
Norfolk, Virginia Beach
Increased mercury in fish
Lake
Whitehurst and Lake Trashmore
Oyster yield decreased
Reduced water quality
18
What can we do?
Yard waste
Sweep clippings back onto the lawn.
Rake up pine needles and leaves and recycle them.
Landscaping
Eliminate bare spots and paved areas.
Plant grass, ground covers or flower beds.
Pet droppings
19
Pick up droppings, bury them, or, if not mixed with
other material, flush down the toilet.
What can we do?
Hazardous chemicals
Store
safely, read manufacturers directions, and
dispose at a household hazardous waste facility.
Car washing
Wash
your car on the lawn or use a commercial
car wash.
Report illicit discharges
At
EVMS, report to EH&S.
At home, call your local Public Works Department.

Effects of Pollutants
Polluted storm water often affects drinking
water sources. This, in turn, can affect human
health and increase drinking water treatment
costs.
You dump it, you drink it!
21
EVMS Concerns
Lawn maintenance
22
Yard waste – do not
blow in the street
Pesticides and
herbicides – apply per
manufacturer’s
instructions
EVMS Issues
Hazardous chemicals
Dispose via EH&S, not in drains
Recycle waste oil and antifreeze
Ice melting products
Spread only on the sidewalk according to
manufacturer’s instructions
Raw materials
Mulch, sand, dirt, rocks
Prevent washing into storm drains
23
Remember…
24
Only Rain Should Go Down the Drain!
