The Columbia Water Treatment Plant first disinfects the water with chlorine, than adds ammonia, forming chloramine.

The disinfection method used in Columbia allows for disinfection of the water through the distribution system all the way to the faucet. Disinfection: Water must be disinfected to prevent bacterial growth and prevent disease causing illnesses like typhoid, hepatitis and cholera.Fluoride is added to meet Environmental Protection Agency recommendations and helps improve dental health. Chlorine may be added before or after filtration to prevent bacterial growth. Filtration: Any particles remaining in the water after the softening process are filtered through layers of anthracite coal and sand.Softened water enables you to use less laundry detergent and reduces scale formed in water heaters and pipes. This process physically removes 50 percent of the hardness causing minerals from the water. Heavy, insoluble particles of calcium and magnesium form and settle to the bottom of the softening basins, and as it accumulates, it is piped to storage lagoons. Softening: Lime is then added to the aerated water, and a chemical reaction occurs between the lime and the calcium and magnesium dissolved in the well water.This oxidation of the well water reduces levels of iron, carbon dioxide and hydrogen sulfide that are naturally found in the water. Aeration: At the treatment plant, the water first flows through aerators and is exposed to air that is drawn through the aerators by fans.Interactive USGS map to access water data from Columbia wells Water resources investigation reportsĢ003: Ground-Water Flow and Ground- and Surface-Water Interaction at McBaine Bottoms, Columbia, Missouri-2000–02Ģ006: Water-Quality Data, 1999-2005, and Ground-Water Level Data, 2004-2005, for McBaine Bottoms, Including the Eagle Bluffs Conservation Area, Columbia, MissouriĢ008: Ground-Water Flow, 2004-07, and Water Quality, 1992-2007, in McBaine Bottoms, Columbia, Missouri The objective of these studies is to monitor the water quality throughout the McBaine Bottoms, to track changes in groundwater quality in the vicinity of the public supply well field and the Eagle Bluffs Conservation Area, and to provide the City with the information needed to protect the well field and ensure good quality drinking water.

In 1992, an agreement among the USGS, the City of Columbia and the Missouri Department of Conservation began groundwater monitoring in the McBaine Bottoms around the City’s wetland treatment units and on the Eagle Bluffs Conservation property. The Integrated Water Resource Plan (IWRP) Final Report was completed in March 2017 and will guide the best combination of strategies for ensuring a sustainable and cost-efficient water supply. The wells average 110 feet deep, penetrating the aquifer near its bottom. Forty-four billion gallons of water fill the area which is constantly replenished by groundwater sources. Water slowly moves through the aquifer, which acts as a natural filtration system. This geological formation is an alluvium and when saturated with water becomes an alluvial aquifer. Long ago, melting glaciers washed sand, gravel and boulders downstream and left thick deposits along the course of the river. The Department welcomes these Fall 2023 additions to our graduate student community: Beatrice Chen (New York University) Juliette Goutierre (Sorbonne-Université, Paris IV) Madeline MacLeod(Stanford University) Renate Mattar (Paris III, la Sorbonne Nouvelle) Samantha Raup (Lycoming College) Max Salata (Yale University) Clarisse Vazquez(University of California San Diego) Jianna Walker (University of Oviedo).Columbia’s water is pumped from wells that tap into a water-filled bed of sand and gravel beneath the bottom land bordering the Missouri River just southwest of the city. Jianna will travel to Spain this October to meet the royal family and to attend the Princess of Asturias Award ceremony. Jianna Walker, MA in French candidate, has received the Premio Extraordinario de Fin de Grado Santa Catalina de Alejandría award, given by the University of Oviedo (Principality of Asturias, Spain). We congratulate Professor Camille Robcis, winner of the 2024 Frantz Fanon Outstanding Book Award for Disalienation: Politics, Philosophy, and Radical Psychiatry in Postwar France, from The Caribbean Philosophical Association!Ĭongratulations go out to Laurence Marie for receiving a Villa Albertine and Albertine Foundation Translation award for her book Inventer l'acteur! Professor Dobie was selected as an inaugural recipient of the Division of Humanities Award for Academic Excellence on March 6, 2024. We mourn the passing of Maryse Condé (1934-2024), Professor Emerita of French and a celebrated novelist.Ĭongratulations to Benjamin Olivennes on the successful defense of his doctoral dissertation, A modern antimodern: Yves Bonnefoy's critique of 20th century art!
