Each year 1.2 trillion gallons of untreated sewage, storm water, and industrial waste are dumped into U.S. waters. Stormwater, according to United States Environmental Protection Agency, is runoff that flowed through any surface modified by humans. With the addition of more urbanized areas, the increasing damages of stormwater which has been revealed as a danger to life. Storm water damages all life, including mankind. More specifically, stormwater damages the aquatic life due to the water…

The water quality of the U-High creek was excellent, however not all creeks have excellent water quality. One way that a creek could get polluted, is the farmers who live and plant their crops near-by. The crops that they plant need to be protected and helped to grow. By doing those things the farmer uses fertilizers and pesticides, which as rain falls and washes away these chemicals, into near-by creeks. The problem with that is, the fertilizers, which contain large amounts of nitrates and…

I was trying to do my post based on the water pollution lab, however, the link would not open for me. Instead I did the lab with the cool google earth application and started doing research on the Santee Watershed in SC. This Watershed is home to, you guessed it, the Santee river. The Santee river is the second largest on the east coast weighing in (not really) at 228.8 km running from the Northwestern side of the state down and out the Atlantic on the Southeastern side. Data from this lab shows…

DISCUSSION: Mike Jones, Director, Tuscarawas County Metropolitan Sewer District (TCMSD) explained the other Ohio Public Works Commission (OPWC) application. Mr. Jones explained this is a sewer project as opposed to water. This application is for Wilshire Hills WWTP. Last year the TCMSD finalized a facilities plan which detailed improvements necessary to ensure that they are able to continue to maintain and operate the Wilkshire Hills WWTP plant and continue to remain in compliance with the EPA…

PAGE 1 –INTRODUCING CYSTAL RIVER Crystal River, located on the Nature Coast of Florida, is known for pristine, crystal clear waters, bays and streams that give the area its name. With more than 70 springs, Crystal River/Kings Bay is the largest winter refuge for manatees on the Florida Gulf Coast and is a National Wildlife Refuge. Over the last 20 years, the springs that feed the river have gone through dramatic changes, which have led to a habitat that is being effected by unwanted algae. If…

control measures and to have more public awareness on the situation. Non-point source pollution control is another important factor to consider to properly address the pollution issue in the YRB. It has been determined that more pollutants come from runoffs through farmlands than through grasslands in the Yellow River Basin. (Ouyang et al., 2010) One way to control pollution is to apply long-term vegetation landscape patterns to retain some of these chemicals. Indeed this measure can help to…

Summer of 2014, my life was changing quite a bit. As I come back from my first year at school in U.S. and more than prepared to live away from home, I pack my bags and go to São Paulo. Although it is very close to my hometown, Santos, it was still a great change: new swim club, new city, new friends. São Paulo it is much known to be a complete chaos: anywhere with 12 million habitants has to be at least somehow different. With too many people comes too many problems: air and river pollution,…

The Dust Bowl was caused by the hands of man and the hands of nature and has resulted in many longer term effects. Because of the Plains states’ successfully wheat business and harvest, thousands and thousands of farmers traveled to the area. However, this influx of farmers led to overgrazing and overplowing of the southern plains. Many of the farmers used a farming technique called dry land farming and destroyed the large areas of grassland. This, coupled with an incredible drought and Great…

4.0 CHENNAI FLOOD MITIGATION MEASURES The mitigation measures have to address flood avoidance, flood tolerance, and flood resistance in an integrated way. The measures that are implemented and the new measures to be developed are meant to control causative factors like uncontrolled urban sprawl, loss of natural drainage, the inadequacy of the storm water drainage system, lack of maintenance of existing systems, increase in impervious surfaces and lack of coordination between stakeholders…

Summary Model Bifenthrin Concentration Prediction The prevalence of bifenthrin in urban Sacramento waters is most likely explained by their wide availability in for the control of ants. Although application amounts reported by professional applicators are not 100 percent correct and that of homeowners are not reported, data from the DPR PUR database indicates that bifenthrin is heavily applied by applicators in urban Sacramento. Additionally, these pyrethroids have a longer half-life than some…
