Sometimes these nets got lost in the water. The detergents went down the pipes with the sewage into the lake. They used poisonous tile and drain cleaners, which flowed into the sewage system. Sometimes these ships spilled oil into the lake. To simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Water is necessary to all living things.
Earth is unique in our solar system having about 70 percent of its surface area covered with water. Of this three percent, almost two-thirds is tied up in glaciers and sea ice leaving approximately one percent of Earth's water available for use by living organisms including humans. This amount of available drinkable water is further reduced by the introduction of pollutants to our water cycle. Clean water is not a limitless resource. Using the available equipment, devise a filtration system that you will use to clean your dirty water sample.
