MA# 3: Is Storm Water Damaging the Puget Sound? Today, storm water runoff is the number one cause of pollution in the Puget Sound. The pollutants contained in storm water runoff are mainly caused by urban runoff, factory farming, and chemicals. Urban runoff can produce pollutants such as gasoline, grease, ammonia, manure, toxic chemicals, and pesticides. In factory farming, the main problem is the production of manure which is extremely bad for the Puget Sound because of the high levels of nitrates it contains. Chemicals carry numerous pollutants which can alter marine life genetics and harm human health. Alternatives to the problems lie in green infrastructure, greenroofs, bio-swales, and porous concrete; however, the solution to the …show more content…

Storm water is a great danger to the environment because it does not receive any treatment before entering waterways. A storm can overload the system, causing it to reach its max capacity. The water treatment plant is then forced to let the overflowing, untreated, water dump into the river. This leads to an almost opaque water, like that found in the Puget Sound. There is an average of 900 billion gallons of untreated sewage water entering larger bodies of water each year in the United States (Barnett). The rain that falls on surfaces drains into bodies of water through storm water collection systems, usually, without treatment. There is a strong relationship between concrete thickness and imperviousness in residential areas, leading researchers to believe that roads create impervious surfaces. When rain down the streets and rooftops, it absorbs all the harmful materials from those surfaces and flows into the major bays and the Puget Sound. The Environmental Protection Agency estimates the remodeling of the aging water system would cost between $300 billion to $1 trillion over the next 20 years (Barnett). The effects of urban runoff are immensely damaging to the Puget Sound. The list of substances and chemicals that can cause damage is extensive. The effects of urban runoff are even more daunting than the causes. The effects include an increase in temperatures, algae blooms, lowered oxygen levels, injured marine life,
