Hydrogeologic and Geospatial Data for the Assessment of Focused Recharge

to the Carbonate-Rock Aquifer in Genesee County, New York

By

James E. Reddy and William M. Kappel

2010

Map 2—This map provides the location of major drainage 

basin divides in Genesee County (Oatka, Black, Tonawanda, 

and Oak Orchard Creek drainage basins) and the location of 

all wells used in the carbonate-rock aquifer study and wells 

located north or south of the study area. The locations of 

wells within the study area were verified using office 

methods, or by field verification; however, the locations of 

wells outside the study area were not verified. Therefore, 

bedrock-surface contours represent a generalized surface, 

especially outside the study area. Anthropogenic features 

(quarries and mines) are also shown on this map. The 

location of agricultural land uses (cropland, hay and pasture, 

in light brown shading) and the “shallow-to-bedrock” soils 

are shown using a hachured pattern. These 

“shallow-to-bedrock” soils have an infiltration rate of 1.42 to 

5.67 inch per hour (in/hr), and bedrock with associated 

solution-widened fractures or karst features may be present 

at or just below the land surface. Four additional 

“shallow-to-bedrock” soils (Aurora, Benson, Wassaic, and 

Rubbleland) that have lower infiltration rates but have been 

associated with manure application and groundwater 

contamination in Genesee County also are shown.
