Publication Abstract

Public Ground-water Supplies in Illinois Hanson, Ross, 1950  Illinois State Water Survey, Champaign, IL,  ISWS B-40 pt.1    Full Text Available

Bulletin No. 40 is published to fill the need for revising and supplementing the contents of Bulletin No. 21 and Supplements I and II, published in 1925, 1938 and 1940 respectively. It is intended not only to include in this Bulletin all of the basic data which were written into Bulletin No. 21 and Supplements I and II but to make Bulletin No. 40 more complete. This is possible because prior to the time of publication of the original Bulletin No. 21 the public-was not aware of the need for accurate records of their water resources. In many cases, no records were kept of water levels and other important well data. At that time a public well could be constructed without notice to the State Department of Public Health. Notice was later made compulsory by law. Possibly ten or fifteen public well supplies were not included in Bulletin No. 21 because their existence was not known to the Water Survey staff.
