[21]: p. 2–9 Nutrient pollution such as nitrates can harm the aquatic environments by degrading water quality by lowering levels of oxygen, which can inturn induce algal blooms and eutrophication. [22] Other agrochemicals such as pesticides and fungicides can enter environments from agricultural lands through runoff and deposition as well.
The section requires states to identify water bodies that cannot meet water-quality standards without control of nonpoint sources. The states must then identify best management practices (BMPs) and measures for those impaired sources, along with an implementation plan. The EPA approves these plans, and if a state fails to develop a plan, the ...
The physical process of sedimentation (the act of depositing sediment) has applications in water treatment, whereby gravity acts to remove suspended solids from water. [1] Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans.
