Water-Quality Variations and Trends in Monument and Fountain Creeks, El Paso andPueblo Counties, Colorado, Water Years 1976-88

摘要

Water-quality data were collected at four stations on Monument Creek and fivestations on Fountain Creek during water years 1976 through 1988. These data were statistically analyzed to determine variations and trends in water-quality properties and constituents. A qualitative comparison using boxplots of water quality among all stations was done for the period of record. A spatial trend analysis was done to compare the water-quality changes among seven of the nine stations for water years 1980 through 1988. Analysis of time-series trends at each station was done to determine if changes in water-quality conditions occurred during the period of record.
