Water-Resources Investigations Report 82-4094

From purpose and content: The purpose of this report is to: (1) describe the general quality of ground water found in the injection zones (permeable strata that accept water) of drainage wells; (2) assess the impact of drainage wells on the water quality of supply wells, particularly public-supply; and (3) establish a data base necessary for future studies

Water-Resources Investigations Report 79-19

Abstract: This report presents selected basic data collected during a study of the water resources of the Clarion River and Redbank Creek basins in northwestern Pennsylvania. Hydrologic information including data on aquifers, water levels, and yields is presented for 1,304 wells. Records for 51 springs are also given. The report contains 83 chemical analyses of water samples collected from 30 stream sites and 300 analyses of water from 196 wells and 43 springs. Also included are 103 trace-elements analyses. Monthly and annual means of ground-water levels for six observation wells are tabulated. Benthic invertebrate data from 136 stream sites are listed. Locations of data-collection sites are shown on 50 page-size reductions of 7.5-minute topographic quadrangle maps
