Water Resources of Monroe County, New York, Water Years 1989-93, with Emphasis on211 Water Quality in the Irondequoit Creek Basin. Part 2. Atmospheric Deposition, 211 Ground Water, Streamflow, Trends in Water Quality, and Chemical Loads to 211 Irondequoit

摘要

This report describes the hydrologic conditions within Monroe County and the211u001eIrondequoit Creek basin during 1989-93 and explains the methods of data analysis 211u001eand the statistical methods used for trend analyses and estimation of constituent 211u001eloads. It provides comparisons of precipitation volumes, and chemical quality of 211u001ebulk atmospheric deposition during 1989-93, with those of the 1984-88 period. It 211u001ealso analyzes seasonal fluctuations in ground-water levels and water-table 211u001egradients in Powder Mill Park in the southern (upper) part of the basin and in 211u001eEllison Park in the northern (lower) part, and includes a comparison of chemical 211u001equality of ground water in the upper part with that in the lower part. 211u001eComparisons are made of streamflow in Monroe County during 1989-93 with 211u001ehistorical streamflow records and with streamflow during 1984-88. Finally, it 211u001eexamines water-quality trends (upward or downward) in Monroe County during 1989-211u001e93, chemical concentrations in 1989-93 in relation to those of the 1984-88 211u001eperiod, and loads and yields of selected constituents transported by Irondequoit 211u001eCreek to the Bay.
