United States Bureau of Mines Bulletin 508
Report from the U.S. Bureau of Mines discussing the anthracite region of Pennsylvania and the efforts to prevent coal-mine drainage into nearby streams. According to the introduction, "The purpose of this report is not to develop a practicable or feasible method or process of treating acid mine water but rather to present available factual and deduced data that may be useful in showing pH range over which the treatment is to take place and the sludge products most likely to be handled" (p. 2)

From Summary: "This report presents data on the corrosive and erosive effects of acid mine waters in the anthracite region on metals and alloys for pumping equipment and drainage facilities necessary to remove or control this water. This report is based on field tests conducted cooperatively by the Armco Steel Corp. and the Federal Bureau of Mines from January 1953 to June 1954 to determine the most suitable materials for constructing pumping equipment designed to handle these acid mine waters.
