Surface runoff

1960s Lake Erie has had many problems with algae. Waste water from the sewers also made their way into the lake, as this was happening factories were dumping pollutants into the lake and waterways. As did fertilizer and pesticides from agricultural runoff. The Ohio Department of Natural Resources and the Ohio Geological Survey, along with Charles E. Herdendorf, said that once scientists realized that phosphorus was to blame…

In the Florida Everglades ecosystem, Phosphorous is the main nutrient that the South Florida Water Management District is attempting to control. Phosphorous is the same nutrient that is a contributing factor to the algae problem in Lake Erie. In South Florida, the main source of drinking water stems from underground aquifers made of porous limestone, that is refilled via the everglades(NPS,2016). In our region, the main source for drinking water for cities, stems from Lake Erie. Thus,…

Egypt receives less than 80 mm of rainfall a year, and only 6 percent of the country is arable and agricultural land, with the rest being a desert. This leads to excessive watering and the use of wasteful irrigation techniques such as flood irrigation an outdated method of irrigation where gallons of water are pumped over the crops. Desertification is a land degradation problem of major importance in the arid regions of the world. Deterioration in soil and plant cover have adversely affected…

This research proposal seeks to test the hypothesis that pesticide run-off from agriculture, even in small amounts, can have a devastating impact on the aquatic ecosystem, in particular that of Daphnia.  For years, pesticides have been known to have devastating impact on the ecosystems surrounding the agricultural centers they are used in. On a regular basis, run-off from farms that utilize both fertilizers and pesticides can seep into the watershed and slowly trickle into bodies of water…

The Murray-Darling Basin is facing many environmental, social and economic factors that affect the life around the basin. The Murray Darling Basin is facing many environmental issues that are caused by humans. The farmers near the MDB use fertilisers that run into the water when it rains and pollutes the water. The pollution from the fertilisers cause algae blooms to form. Another way that humans have affected the environment is through the use of irrigation for crops. The use of irrigation…

Discussion: Mudboils cause structural failures since they are suspensions of gravel, clay, silt and fine sand creating an unstable surface. Since the beginning of persistent mudboil activity in the 1970’s, natural landscapes and engineered features have become subject to land-subsidence as mudoils continually deteriorate the areas in their path (Tresohlavy 2003, pp. 27). Petroleum pipeline rerouting, telephone cable burials, and the collapse of bridges have demonstrated the true capabilities of…

Problem Statement Industries are generated waste water, which contain dyes and pigments in waste water. Characteristically high in colour and organic content (Grag, et al., 2004). Dyes are widely used in industries such as textile, rubber, paper, plastic, and cosmetic. There are many of dyes exist in industries and one of them is methyl red and through nano zerovalent iron removal of dyes from waste water. Dye industry effluents constitute one of the most problematic wastewaters to be treated…

rivers or lakes. Waste disposal pipes can be another example. Non-point source: Release of potential pollutants from a range of activities without a single or definite source. Agricultural facilities can be considered as non-point sources. Stormwater runoff, especially during heavy rainfall, in agricultural land/farmland may contain harmful substances such as pathogens and nutrients, and then enters waterways. Also, sedimentation is one of the main form of non-point source pollutions.…

The water quality of the UHS creek was found to have excellent water quality. There are other creeks, however, that have poor water quality. One way humans negatively affect water quality is by fertilizers and pesticide runoff, mainly used by farmers. Fertilizers and pesticides that drain into a river increases the amount of nitrate and phosphate considerably. This leads to a massive amount of algae growth, known as eutrophication. When the algae die, they are broken down by the bacteria which…
