Abstract

Water-quality data collected at 16 water-quality-sampling sites in the James River Basin during 1949-95 were statistically summarized. Analysis of variance of data ranks was used to make comparisons among sites for selected constituents that had 20 or more analyses per site. Statistically significant differences among sites were indicated for specific conductance, dissolved solids, major ions, and nutrients. Regression analyses indicated negative relations to streamflow at most sites for specific conductance, dissolved solids, hardness, and most major ions. Several nutrients related positively to streamflow. Seasonal trends were prevalent for calcium, magnesium, sodium, potassium, sulfate, and chloride. Seasonal trends for nutrients were less frequent. Time trends were indicated for one or more constituents at all sites.
