SOURCE POLLUTION CONTROL PROGRAM GUIDE
COMMON HAZARDS TO WATER RESOURCES
General
Many products commonly used in and around our homes are hazardous to both the
environment and people. If used improperly, these products can end up in nearby surface or
ground waters. This document provides alternatives, where possible, for many products and
common practices that can reduce the potential for adverse impacts to those water resources.
The term commonly used to describe environmentally conscientious practices is "Best
Management Practices" (BMP). Many BMPs are incorporated into the design of your
subdivision. BMPs described herein include "good housekeeping" practices that everyone can
use.
It has been said that the average home today contains more chemicals than the average
chemical lab of 100 years ago. When these chemicals are used industrially, they typically are
subject to various health and safety standards. However, many of these same substances can
be used freely and carelessly in our homes. Typical residential pollutant sources are classified
as either "point" or "non-point" sources. A point source pollutant is one in which the contaminant
can be traced to a specifc location or locations. Non-point pollutants are more difficult to locate.
Stormwater is a good example wherein tiny bits of contaminant collect aver many acres of
runoff, eventually reaching a single point. However, the source of the pollutant is anything but a
"point" source.
A. Point sources of pollutants
1. Household products
Many cleaning agents, solvents, polishes, etc. commonly used in the home are
considered hazardous. These products may be toxic, corrosive, reactive, flammable,
or carcinogenic. It is critical that these products are handled with care and are
properly disposed. A list of common household hazardous materials is presented in
Table 1.
In addition, many hazardous household chemicals persist for long periods of time in
the environment. Manufacturers may truthfully state that a product is
"biodegradable"; most products are biodegradable, but what is important is the rate
at which they are broken down and the products they are broken down into. The
term "biodegradable" is somewhat misleading unless the product rapidly degrades
into harmless substances.
It is important to note here that the term "biodegradable" curzently has no legal
defnition in this state. Consequently, any product can use this term according to the
manufacturer's own definition. This definition may not be at
1of 14
all similar to the consumer's perception.
2. Automotive care products
Common automotive fluids such as oil, gas, antifreeze, degreasers, etc, are easily
spread by small amounts of water and can cause significant damage to area ground
and surface waters. Table 1 presents a list of these common items and Table 2
suggests alternatives or handling tips to reduce the potential for negative
environmental impacts.
B. Non-point sources of pollutants
1. Yard care products
Pesticides (including insecticides and herbicides) and fertilizers are commonly used
by homeowners in the quest for bigger, healthier plants and greener lawns. These
chemicals are often overused. Many times, homeowners apply too much chemical
or apply the right amount but at the wrong time. (Such as before heavy rains or any
time the plants will not be able to absorb the chemicals.) Excess chemicals are
easily introduced into stormwater runoff and can cause algae blooms (fertilizers) or
kill off aquatic organisms (pesticides) in surface waters. Large quantities of fertilizer
can negatively impact nitrate levels in drinking water well supplies as well.
2. stormwater runoff
stormwater runoff needs to be treated because it carries litter, oil, gasoline,
fertilizers, pesticides, pet waste, sediments, and anything else that can float, dissolve
or be swept along by moving water. Left untreated, polluted stormwater can reach
nearby waterways where it can harm or kill aquatic life. Untreated stormwater can
pollute groundwater in similar ways. Nationally, stormwater is recognized as a major
threat to water quality. Remember to keep everything out of stormwater systems
except the rainwater they are designed to collect.

II. REDUCING IMPACTS ON WATER RESOURCES
General
The following ideas should help you reduce the risks of stormwater and ground water
contamination from many common products or practices. From a waste management
standpoint, automobile maintenance is best done by professionals at facilities designed to
handle, store, and dispose of waste products properly. Many of these facilities do an excellent
job of dealing with waste oils, antifreezes, other fluids, batteries and tires. If you do repair or
maintain your car at home, please consider the tips presented in this plan.
Fertilizing a lawn can be done in an environmentally sensitive manner. Also, rather than
bringing out the sprayer whenever a pest infestation occurs in the garden, consider using other
alternatives. Evaluate all factors that might affect the garden, including environmental effects,
before chemicals are applied. Pesticides should only be used as a last resort. Some proven
tactics that can be used to decrease the use of pesticides are discussed below.
A. Household operations
1. Read the label of products before you buy them. Toxic product labels carry many
warnings. Either bypass such products entirely or buy them in small quantities. If
you cannot use the entire product, try to give it away instead of disposing of it.
Thurston County periodically facilitates product exchanges for leftover paints and
other hazardous wastes. Call the Thurston County Health Department at 754-4111
for more information.
2. Buy detergents that contain little or no phosphorus. Phosphorus can cause algae
blooms if washed into lakes or streams. Most detergents that are low or phosphate
free are labeled as such.
3. Use no more than the manufacturer's suggested amount of any cleanser. (More isn't
necessarily better.)
4. Products such as oven cleanser, floor wax, furniture polish, drain cleaners, and spot
removers often contain chemicals that are toxic. Buy the least toxic product
available, and use anon-toxic substitute if one can be found. Ovens, for example,
can be cleaned by applying table salt to spills, then scrubbing with a solution of
washing soda and water. Table 2 lists substitutes for many commonly used
household products.
If it is necessary to use a product that contains toxic chemicals, use the product only
as directed. Do not combine products, as they may become more dangerous when
mixed (example: mixing chlorine bleach and ammonia produces dangerous gases).
Use eye-wear and rubber gloves as appropriate. Contact the Hazardous Substance
Hotline at 1-800-633-7585 if you have any questions regarding disposal of a product
or empty container. The County has both hazardous waste collection days and
3of14
permanent facilities where residents can bring hazardous wastes. Call the Thurston
County Health Department at 754-4111 for more information.
5. Many chemicals left over from some activities such as photography and auto repair
are hazardous and should not be flushed down the sink or toilet. This is especially
important if your home is hooked up to a septic system. Toxic chemicals can kill
bacteria in the tank that treat sewage and can also pollute water supply wells.
6. Be sure that all toxic material containers are clearly marked.
7. Common (not automobile) household batteries are one of the largest sources of
heavy metals (such as lead, nickel, cadmium, and mercury) found in landfills.
Instead of throwing batteries away, dispose of them at a hazardous waste collection
site.
B. Automotive care and maintenance
1. Cars should be serviced regularly. Leaky lines or valves should be replaced.
Dumping oil, degreasers, antifreeze, and other automotive liquids into a stream or
storm drain violates city, county and state law. Do not dump them onto the ground
because they will end up in stormwater runoff or in groundwater. Do not use oil to
reduce dust levels on unpaved areas. Instead, recycle used oil and antifreeze.
(Keep them in separate containers.) Call the Recycling Hotline at 1-600-RECYCLE
or call the Thurston County Health Department for the location of the nearest
recycling center. You may also call your local automotive service centers to see if
they take oil for recycling. (Some also take used oil filters.)
3. Wrap empty oil and antifreeze containers in several layers of newspaper, tie
securely, and place them in a covered trashcan. (Antifreeze tastes sweet but is
poisonous to people, Flsh, pets, and wildlife.)
4. Sweep your driveway instead of hosing it down. Fluids and heavy metals associated
with automobiles can build up on driveway surfaces. When cleaned with a garden
hose, these contaminants can be washed into local surface or ground waters.
Sweeping up sediment and disposing of it properly can reduce the impact on our
water resources.
5. Wash vehicles on the lawn or in a location where soapsuds can be directed onto the
lawn or another vegetated area. This will help to keep soapsuds from washing into
the storm drain system or local surface water. (Your stormwater pond is not
designed to cleanse soapy water from washed cars.)
6. Small spills of oil or other Fluids can be absorbed by using materials such as kitty
litter or sawdust. Wrap the used kitty litter and any contaminated soil in a plastic bag
and then place it in the garbage. If a spill reaches surface water, you must notify the
nearest regional office of the Department of Ecology immediately! Southwest
Regional Office number: 407-6300. There are foes for failure to notify the
appropriate agency when a spill occurs.
4of14
7. De-icing chemicals, usually a form of salt, can harm concrete less than three years in
age, burn vegetation, and are corrosive to cars and other metal objects. De-icing
chemicals and their additives can also be toxic. (Cyanide is formed from the
breakdown of a common anti-caking agent used in de-icing chemicals.)
Urea salts are an alternative to other types of salt de-icers, but great care must be
used in applying them. These salts contain large quantities of nitrogen, which can
severely burn plants and encourage algae growth in lakes if over-applied. The use
of these chemicals should be minimized or avoided. Instead, shovel walks clear and
apply a dusting of sand to improve footing.
C. Landscape design and maintenance
1. One of the best methods of reducing impacts to water resources is by using
landscaping materials that do not require extensive care. Native plants have
adapted themselves to our region, particularly their root structure and water needs.
These plants have also built tolerances over the centuries to local pests and disease.
By using native plants in the landscape, we are less likely to need fertilizers,
herbicides, and pesticides. Native plants are also more tolerant of drought
conditions and typically require less water.
Native plants come in all shapes and sizes so there is probably one that will fit into
your landscape plans. There are deciduous and evergreen varieties of trees, shrubs,
and groundcovers. Following is a brief list of just some of the more common
varieties of native plants. Contact your local garden supply store for more ideas on
use of native plants in your garden.
Evergreen Plants:
Trees -western red cedar, douglas fir, western hemlock
Shrubs -rhododendron, evergreen huckleberry, tall Oregon grape
Ferns -lady fern, sword fern, deer fern
Groundcover- manzanita, kinnikinnik, common juniper
Deciduous Plants:
Trees -big leaf maple, pacific dogwood, bitter cherry
Shrubs-western azalea, nootka rose, red huckleberry
2. The lawn is a major component of the landscape. Selection of a grass well suited to
our area is an important step in reducing the impact to water resources. The
National TuAgrass Evaluation studies various types of grasses for their resistance to
insects, drought tolerance, seasonal appearance, density, the strength of their sod,
and leaf texture. Based upon these characteristics, specific grass types are
recommended for specific areas throughout the country. Fescue and perennial rye
grass are recommended for this area.

3. Use of native plants will greatly reduce the need for fertilizer. Use of mulch may
eliminate the need altogether. Mulch acts as a physical barrier to weeds and is an
excellent alternative to herbicides. Mulch can be compost, bark or wood chips, or
leaves and grass clippings. It should be spread around the base of plants and within
flowerbeds. The recommended depth of mulch varies between plant varieties but
should typically be two to four inches.
4. Proper use of fertilizers yields better plants and reduces negative impacts to our
water resources. Fertilizers typically contain high levels of nitrogen and phosphorus,
both of which can damage ground and surface waters. The following are a few tips
to optimize the use of fertilizers in your garden.
- The first step in fixing a problem is to know what that problem is. Therefore,
before applying any fertilizer, test your soil. Existing soil conditions,
particularly nitrogen, phosphorus, potassium, and pH levels, can be easily
determined by using kits available at garden stores or from the WSU
Cooperative EMension. Applying fertilizer before knowing the components of
the soil could lead to over loading certain areas that may impact our water
resources.
Proper fertilization is important in maintaining a healthy lawn that resists
environmental stress, including competition with weeds and moss and
drought stress. Because Spring and Fall are periods of optimal growth, these
are the most important times to fertilize. The use of slow release fertilizers is
recommended. Natural organic and synthetic organic fertilizers (such as
IBDU, sulfur or polymer coated urea, or methylene urea) behave similarly
once they are applied to the soil. Although some people feel that natural
organic fertilizers provide added benefits to soil health, research has not
shown this to be true as a general rule. The natural organic nutrient sources
in these products are often supplemented with synthetic plant nutrients
anyway. The most important thing to remember is to use a slaw release
fertilizer. Extensive research around the country has shown that when these
materials are applied properly there is very little risk of surface or
groundwater contamination, and they provide an even feeding, which is better
far your lawn. Remember to sweep granules off pavement to prevent
washing into storm drains.
Turf fertilization practices for the entire year are built around what is done in
the fall. Apply fertilizer in early to mid September to promote regrowth from
summer stress. Another application in November is important in keeping the
grass competitive with moss through the winter. If you fertilize in November,
you probably don't need an early Spring fertilization. If not, your lawn will
probably be ready for fertilizer in the Spring. Again, use a slow release
fertilizer so that you don't promote a big flush of growth. Fertilize again in
early June so that the grass has the nutrients it needs to grow at a moderate
rate through the summer stress period.
If you want to maintain a lawn of moderate quality, a minimum of three
fertilizations through the year is needed. Additional light fertilizations can be
6of14
added if you are looking for a higher quality lawn. In general, you should
apply no more than one pound of actual fertilizer nitrogen per 1000 square
feet at a time, although this rate can be increased to 1.5 pounds in the fall
when using slow release products. (If the fertilizer analysis is 24-4-12, for
example, it contains 24% nitrogen.) To apply 1 pound of N per 1000 square
feet, you need to apply 4.2 pounds of fertilizer (1 - 0.24 = 4.2). Return
clippings (grasscycle) when you mow to recycle nutrients into the lawn.
- Water plants and lawns before fertilizing. Water enough to dampen the
ground thoroughly, but not enough to cause surface runoff. Dampening the
soil prevents fertilizer from being washed from the surface of dry soil in the
first rain or watering after application.
- Use mulching mowers to return grass clippings directly to the lawn. Essential
nutrients from the decomposed grass can then be retained in the soil thereby
reducing the need for fertilizer.
- Many soils can benefit from the use of organic fertilizers such as compost or
peat. These substances add nutrients to soil and increase the porosity of the
sail as well as its ability to hold water.
5. Proper watering can help build strong plants resistant to drought, pests, and disease.
Water infrequently but enough to dampen soil down to 10-inches. Be careful not to
water so rapidly that water runs off the surface. Infrequent watering promotes
shallow root depths making the plants susceptible to damage during periods of
drought. Unhealthy plants are easy targets for pests and disease. Also, water
during early morning hours rather than during the day or at night. Irrigating during
the day loses a sizable amount of water to the atmosphere through evaporation.
Watering at night can lead to mold and fungi growth on plants left damp over a cool
night.
D. Pest control
1. Use natural predators and pathogens. Because chemical sprays generally kill
beneficial insects along with the target pest, it may be necessary to introduce natural
predators back into the garden. Ladybugs, lacewings, predatory wasps, and
nematodes are all commercially available. Garter snakes and toads are also
predators and should not be eliminated from the garden.
Some bacteria, viruses, and insect parasites are specific to pests and will not harm
other insects or animals. A commonly used bacterium in the Puget Sound area is
Bacillus thuringiensis (Bt), which is intended to control infestations of tent caterpillars.
Products containing Bt are available at your nursery.
2. Many times a change of habitat can control pest infestations. Removal of old tires
can cut down on the mosquito population by removing a convenient water-filled
location for them to breed. Crop rotation, even in a small garden, can reduce the
number of pest infestations. Removing last year's leaves from under rose bushes
7of14
can cut down on the incidence of mildew and blackspot, as these fungi ovenvinter in
dead leaves.
3. Crops that can ovenvinter, such as leeks and carrots, should be planted in the fall.
This gives them time to become established before pests arrive in the spring.
4. Many eggs, larvae, cocoons, and adult insects can be removed by hand. Be sure
that the insect is properly identified prior to removing it so beneficial insects are not
destroyed in error. Drowning insects in plain water or spraying them with soapy
water are alternatives to squashing them.
5. Plants native to this area are often more resistant to pests and climate than are
introduced plants. Many plant cultivars have been developed that are resistant to
diseases such as verticilium wilt and peach leaf curl. Grass seed mixes are also
available for lawns that require less watering, mowing, and chemical use.
6. Plants, such as hostas, that require some shade are more susceptible to pests when
they are grown in the sun. Plants that are not properly fertilized or watered are less
vigorous in growth and tend to attract pests. Plants that prefer an acid soil, such as
azaleas, will perform better and be less susceptible to pests when they are grown in
soil with the proper pH.

E. Pesticide management
1. Know what pest you are spraying for. Use the pesticide according to the
manufacturer's instructions and buy only the quantity needed. Many pesticides have
a limited shelf life and may be useless or degrade into even more toxic compounds if
kept on the shelf.
2. Do not apply more than the specified amount. Overuse can be dangerous to your
health as well as wildlife and the environment. If more than one chemical can be
used to control the pest, choose the least toxic. The word "Caution' on the label
means that the chemical is less toxic than one that is labeled "Warning".
3. Do not spray on windy days, in the morning of what will be a very hot day, or when
rain is likely to occur. Herbicides can drift and injure valuable ornamental plants in
either yours or your neighbor's back yard. Do not water heavily after application.
Plants should be lightly watered BEFORE application to prevent burning the foliage,
and to help evenly spread the chemical.
4. Never apply pesticides near streams, ponds, or wetlands (exception: approved
applications for aquatic weeds). Do not apply them to bare eroded ground
(exception: use of low toxicity herbicides such as Round-up to allow growth of
desired planting in small areas). Many pesticides bind to soil particles and can be
easily carried into a stream or storm drain.
5. Pesticides should be stared well away from living areas. Ideally, the storage area
should have a cement Floor and be insulated from temperature extremes. Always
keep pesticides in their original containers with labels in tact. Labels often corrode
and become illegible in this climate and may have to be taped onto the container.
6. Federal law requires all pesticides to be labeled with an appropriate disposal
method. Leftovers should never be dumped anywhere, including a landfill. Take
unwanted pesticides to the County's "Hazardous Waste Collection Days" or Hazo
House at the landfill. Call the Thurston County Waste Line at 1-800-624-1234, ext.
4348 for more information.
7. Empty containers should be triple-rinsed and the rinse water used as spray. Once
containers are triple-rinsed, they are not considered hazardous waste and may be
disposed of in most landfills. However, call your local landfill before putting the
container in the garbage.
8. If a pesticide is spilled onto pavement, it can be absorbed using kitty litter or
sawdust. The contaminated absorbent should be bagged and labeled and taken to
Hazo House.
9. If a pesticide is spilled onto dirt, dig up the dirt, place it in a plastic bag and take it to
Hazo House.
10. Many pest control companies and licensed applicators have access to pesticides that
