eliminated from the water. Cryptosporidium is a parasite that causes watery diarrhea and is highly resistant to chlorination, which is why UV light must be used. Other countries around the world are experimenting with different treatment methods to eliminate chemicals that are not removed throughout the water treatment process. An article written in the National University of Colombia talks about adding a double filtration to the water treatment process. It is suggested that granular activated carbon be added to the process to reducethe chemical atrazine from water. This chemical contaminates water by runoff from fields because it is widely used in pesticides. According to (Fuentes-Lopez, Amezquita-Marroquin & Torress-Lozada, 2018), Atrazine, was evaluated during the conventional treatment process, followed by double filtration with two adsorbent granular media (vegetal and mineral GAC), which resulted in an efficient reduction of UV254 (86%) and Atrazine (99%). UV254 is a test method used to measure turbidity in water, which is the presence of organic matter. Solid Waste LandfillsOnce the municipal solid waste (MSW) is collected from homes and businesses, it must be taken to a landfill. In the past, solid waste was taken to dump sites and left there. Dumpsites became illegal and were replaced by landfills. This is the oldest method of disposing of solid waste (Nathanson & Schneider, 2015). Solid waste (SW) is now buried in a sanitary landfill. Every day, the misuse is covered with soil. This controls the spread of vector-borne diseases spread by rats, mice, mosquitoes, and flies. Solid waste landfills are designed and built to protect the public and prevent harm to the environment. Landfills are required to have certain features according to the EPA to be operational. Two essential features are site selectionand leachate containment.Site Selection
UNIT VIII ESSAY7A landfill site cannot be placed anywhere, so careful consideration must be taken. Site selection is one of the most essential features of a landfill because it must have enough volume, capacity, accessibility, and hydrogeologic conditions for optimal use. Landfills must have a lifespan of 25 years until they can reach capacity. The soil that is used to cover solid waste adds 20% to the volume of the landfill which must be considered during the planning stages. Leachate Containment Solid waste contains a liquid that must be controlled to prevent it from leaking into theenvironment. This contaminated liquid is called leachate. In the past, natural soil was relied onfor absorbing the contaminants in the fluid, but that was terminated. This was called naturalattenuation. Now leachate must be contained, controlled, and treated. This is also known as acontainment landfill. Containment landfillsare usually placed in areas that are dry without rain.
