Following are excerpts from a talk given by Alexandria Sanitation Authority General Manager and WEF Board of Trustees member Karen Pallansch at a May 24 scholarship awards lunch hosted by the Federal Water Quality Association in Washington, D.C.
According to the Center for Disease Control, one of the greatest achievements of the 20th century was the understanding of the importance of excellent water sanitation in our world. Starting in the early 1900’s and continuing over the next several decades, engineers and scientific professionals, with nothing more than a #2 pencil, graph paper and slide rule, developed methods to clean the water made dirty by each and every one of us, and they found ways faster and more efficient than nature alone could accomplish.
