Exelon Application states, “The cumulative impact of the Project to the system is to provide the last site of sediment storage along the Susquehanna River before sediment reaches Chesapeake Bay. This has benefited Chesapeake Bay by providing a means by which the quantity of fine-grained sediment and associated nutrients, sources of water quality impairment, reaching the Bay are reduced.”.

Stream Ecology. 1/22/2009. Stream Load Classifications. Bed load. : Sediments moving predominantly in contact with or close to the stream bed.. Suspended load. : Sediments that move primarily suspended in fluid flow but may interact with bed load and is comprised primarily of silts and clays and sometimes sand. Suspended load has a continual exchange between sediment in fluid flow and on the bed as it is constantly being entrained from the bed and suspended while heavier particles settle out from the flow to the bed. .  sediments (. bio.  = life, . generare.  = to produce) are sediments made from the skeletal remains of once-living organisms.

Introduction. . Mercury has an affect on everything. Between soil on land, and sediment in water, sediment contains more mercury from being in the contaminated water.  Mercury has a huge effect on organisms. When mercury from power plants goes into the air, the mercury falls from the clouds when it rains, and lands in water, on the ground, and pollutes everything. Mercury affects how quickly organisms move, and makes them less tolerant to diseases, or harmful things. Mercury affects many different systems throughout the organism's body. (Mercury and health).
