Wastewater is considered a potential source of Wastewater is considered a potential source of pollution because it may—especially if it is pollution because it may—especially if it is untreated or only partially treated—contain organic untreated or only partially treated—contain organic and inorganic materials that can be hazardous to and inorganic materials that can be hazardous to both humans and other life forms. In many streams, both humans and other life forms. In many streams, treated wastewater treated wastewater may actually be cleaner than may actually be cleaner than what is already contained in the stream; however, what is already contained in the stream; however, treated, untreated, or partially treated wastewater treated, untreated, or partially treated wastewater may also contain small amounts of radiation or may also contain small amounts of radiation or toxics that increase the temperature of waters, toxics that increase the temperature of waters, affecting aquatic wildlife and habitat. Finally, affecting aquatic wildlife and habitat. Finally, discharged wastewater, especially if it is untreated discharged wastewater, especially if it is untreated or partially treated, may lower the amount of or partially treated, may lower the amount of dissolved oxygen in the receiving stream (oxygen is dissolved oxygen in the receiving stream (oxygen is required by microorganisms that consume the required by microorganisms that consume the organic material).organic material).

Wastewater flows from domestic sources average about Wastewater flows from domestic sources average about 100 gallons per day for each person served. During dry 100 gallons per day for each person served. During dry weather, however, highest flows are about twice the weather, however, highest flows are about twice the average flow, while minimum flows are only about half average flow, while minimum flows are only about half the average flow.the average flow.

Furthermore, disposal costs are Furthermore, disposal costs are reduced when the volume of waste is reduced when the volume of waste is decreased. This can also lead to a decreased. This can also lead to a reduction in workplace exposures to reduction in workplace exposures to hazardous materials which can affect hazardous materials which can affect workers' health and hence, their workers' health and hence, their productivity. If less waste is produced, productivity. If less waste is produced, there will also be a diminished need for there will also be a diminished need for on-site storage space. Furthermore, by on-site storage space. Furthermore, by preventing pollution there will be a preventing pollution there will be a greater likelihood that a company will greater likelihood that a company will be in compliance with local, state, and be in compliance with local, state, and federal compliance statutes. Finally, as federal compliance statutes. Finally, as community pillars, businesses shoulder community pillars, businesses shoulder an important responsibility for an important responsibility for protecting the environment and protecting the environment and natural resources for their own good as natural resources for their own good as well as that of society. well as that of society.

Do not let the water run while brushing your teeth or washing your face (you can save up to 5

gallons). Do not leave the water running if you wash dishes by

hand. Rinse all your dishes at once by using a dish rack

placed in the sink. Only run your dishwasher and washing machine

when they are full. Do not open fire hydrants on hot summer days

because water needed to fight a fire will not be available in an emergency. Also, opening fire

hydrants is illegal. Do not throw in the trash, pour down the drain, or

dump on the ground paint, antifreeze, motor oil, and other household hazardous wastes, because

they can migrate to your water source. Dispose of tissues, dead insects, and other waste in

a trash can rather than a toilet. Plant native plants instead of traditional lawn grass

to avoid the use of herbicides, pesticides, fertilizers. Do not dump used motor oil on the ground or into

sewers; throwing motor oil in the trash is illegal. Recycling centers and many service stations accept

used motor oil for recycling.
