Description of the problem:
Las Animas, Colorado, a rural community with a marginal economy and difficult water problems, recently put its new reverse osmosis plant on line.
Las Animas (population approximately 2,660) lies over the alluvial aquifer of the Arkansas River on the plains of southeastern Colorado. Water quality data in this basin has been evaluated and documented through several US Geological Survey studies. The quality of the water is affected by the extensive use and reuse of the Arkansas River water for irrigation. Evapotranspiration of the irrigation water concentrates the dissolved solids. The degradation of the water is illustrated below, starting at Pueblo.
