Basic Data Report 1
Introduction
Baltimore County is in north-central Maryland. It is bounded on the north by the Pennsylvania border, on the west by Carroll and Howard Counties, on the south by Baltimore City and the Chesapeake Bay and on the east by Harford County. About 80 percent of the area of Baltimore County lies in the Piedmont physiographic province. The remaining 20 percent of the area is in the Coastal Plain province. Baltimore City is not a political subdivision of Baltimore County, but is a political unit equivalent to a county. The county has a land area of 610 square miles, of which approximately 65 percent is used for agricultural purposes. The population of the county was 492,428 in 1960, most of which is concentrated in the urbanized areas adjacent to Baltimore City. Approximately 20 percent of the industry of Maryland is located in Baltimore County, and most of that is in the Coastal Plain segment.
This report presents well and spring records collected by the U.S. Geological Survey in cooperation with the Baltimore County Department of Public Works, and the Maryland Geological Survey. It makes available basic ground-water data that will be useful in the planning of waterresources development. The report is the result of an inventory of 5,265 wells and 48 springs. The fieldwork was done chiefly during 1952-54 and 1964-65. The basic source of the well information is the permits and completion reports furnished by the drillers to the Maryland Geological Survey during the period June 1945 to May 1964. Since 1964 well permits have been issued by the Maryland Department of Water Resources and a few wells included are based on records from this agency.
