STORM WATER AWARENESSEastern Virginia Medical School
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.

Storm Water Program
4
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.
What is it?
5
Runoff collects and transports soil, pet manure, salt, pesticides, fertilizer, oil and grease, leaves, litter and other potential pollutants.
Pollutants
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.
Yard Waste/Fertilizer
7
Rinse water, as well as grease and oil, from washing your car drains to the curb then to the storm sewer.
Washing the car
8
Pet droppings contain bacteria and other pathogens.
When our pets leave those little surprises, rain washes all that waste into our storm drains.
Scoop the poop!
9
Paint, pesticides, used motor oil, solvents, etc. At EVMS, dispose via Environmental Health & Safety
(EH&S) At home, Household Hazardous Waste Facilities and
Collection Schedule For more information, contact SPSA

Household Hazardous Waste
12
Rain carries pollutants to streams, wetlands, lakes and coastal waters.
Storm drains carry runoff from a neighborhood to the nearest body of water. Storm sewers DO NOT carry storm water to wastewater
treatment plants!
Where does it go?
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.
Why the concern?
Algae
14
Household hazardous wastes like insecticides, pesticides, paint, solvents, used motor oil, and other auto fluids can poison aquatic life.
Debris – plastic bags, six-pack rings, bottles, and cigarette butts – washed into water bodies can choke, suffocate, or disable aquatic life.
Why the concern?
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.
Illicit Discharges
17
Exxon Valdez oil spill – 1989 11 million gallons of oil
spilled
Do-it-yourselfers Home oil change 200 million gallons per
year
Oil Spill?
18
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
Impacts
19
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 Pick up droppings, bury them, or, if not mixed with
other material, flush down the toilet.
What can we do?
20
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.
What can we do?
21
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!
Effects of Pollutants
22
Lawn maintenance Yard waste – do not blow
in the street Pesticides and herbicides
– apply per manufacturer’s instructions
EVMS Concerns
23
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
EVMS Issues
24
Only Rain Should Go Down the Drain!
Remember…
