How does Pollution Effect the Water We Drink? TEKS § (b)(6)(c) Anne M. Berry

Where is all the water located?  97% of the earth is water!  Only 3 % of all the earth’s water is freshwater, streams, lakes, groundwater  Only 1% of the freshwater available is usable for human consumption! WOW!

Two Types of Pollution Type One: Point Source Pollution A sewer pipe that empties Directly into a river or stream Any other source that empties Directly into a waterway

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

Two Types of Pollution Type Two: Non Point Source Contamination that Enters water through Various ways Pesticides Fertilizers Detergents Chemicals from Industry, automobiles And households

Point Source Contamination  The combined authorized municipal and industrial discharge of wastewater — about 61.5 billion gallons per day — is enough to fill Texas Stadium home of the Dallas Cowboys 79 times over with wastewater every day.  Wastewater flows from domestic sources average about 100 gallons per day for each person served. During dry weather, however, highest flows are about twice the average flow, while minimum flows are only about half the average flow. 

What do you think about this? What do you think about this? To flush a toilet 5 to 7 gallons To run a dishwasher 15 to 25 gallons To wash dishes by hand 20 gallons To water a small lawn 35 gallons To take a shower 25 to 50 gallons To take a bath 50 gallons To wash a small load of clothes in a washing machine 35 gallons To brush teeth (running water continuously) 2 to 5 gallons The average American uses 140 to 160 gallons of water per day.

What can YOU do???  Adopting pollution prevention practices and techniques often benefits industry by lowering a company's operational and environmental compliance costs. By preventing the generation of waste, P2 can also reduce or eliminate long- term liabilities and clean-up costs. Furthermore, disposal costs are reduced when the volume of waste is decreased. This can also lead to a reduction in workplace exposures to hazardous materials which can affect workers' health and hence, their productivity. If less waste is produced, there will also be a diminished need for on-site storage space. Furthermore, by preventing pollution there will be a greater likelihood that a company will be in compliance with local, state, and federal compliance statutes. Finally, as community pillars, businesses shoulder an important responsibility for protecting the environment and natural resources for their own good as 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.
