    Adoption of slow sand filter technology spread throughout Europe in the mid- to late 1800's and by 1872, the technology had reached the United States. Poughkeepsie, New York was the first American town to build a slow sand filter (Hendricks, 1991). Additional installations followed, and by 1899, twenty such filters were in use in the,
