Bulletin, geologic series 30

The report is based upon field investigations made during the period of about four years beginning July 1, 1924, by the author working in cooperation with the Divsion of Waters in studying the ground water resources of the State. This report is the first of a series which are being prepared on ground water conditions in several areas throughout the State where large supplies of water are being utilized for potable and public use. The necessity for more accurate knowledge of our water resources,in order to plan intelligently future water supply developments, amply justifies these investigations
