water is affected in many different ways by phosphates Phosphorus is usually present in natural waters as phosphate(Mcwelsh and Raintree‚ 1998). Phosphates are present in fertilizers and laundry detergents and can enter the water from agricultural runoff‚ industrial waste‚ and sewage discharge (Outwater‚1996) . Phosphates‚ like nitrates‚ are plant nutrients (Phosphates‚ 1997). When too much phosphate enters a water‚ plant growth flourishes (Phosphates). Phosphates also stimulate the growth of

In nature‚ organisms of all shapes and sizes greatly affect the ecosystems which surround them. As African elephants stomp through the savannah‚ pushing over trees and crushing shrubs‚ the forest is kept from overtaking their grasslands. The predatory nature of wolves in the Pacific Northwest prevents overpopulation as they hunt out rabbits and deer. While ecosystems rely on animals to maintain a healthy status‚ they also rely on the environment to keep from drastic change. However‚ glaciers all

Assam had a record of 169.5 mm in 24 hours on the 22nd of July and 900mm in total for July. This long duration of precipitation left the soil completely saturated and as the rate of precipitation quickly exceeded the infiltration capacity. The surface runoff increased dramatically and in turn as did the river’s discharge. Another aspect which lead to the flooding was that the peak discharge of the river Ganges and the Brahmaputra coincided so this increased the river discharge downstream. These physical

absorbed by grass and vegetation‚ some evaporates‚ and the rest travels over the land as surface runoff. Floods occur when ponds‚ lakes‚ riverbeds‚ soil‚ and vegetation cannot absorb all the water. Water then runs off the land in quantities that cannot be carried within stream channels or retained in natural ponds‚ lakes‚ and man-made reservoirs. About 30 percent of all precipitation is in the form of runoff small and that amount might be increased by water from melting snow. River flooding is often

The plant manages to do this by running the water through a series of operations‚ prior to releasing it back into the environment. The WPC (water pollution control plant) of Akron usually receives about 70-75 million gallons of water to treat a day. On days that it rains‚ over 100 million gallons of water is collected‚ because of the ‘combined’ sewers of the water runoff‚ through a pipe that is 110 inches in diameter
