Artificial-Recharge Experiments and Operations on the Southern High Plains of Texas and New Mexico

Description: Abstract: Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells. Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopment through pumping and surging significantly prolongs the life of recharge wells under some conditions. Surface spreading is little practiced on the High Plains, but locally may be a feasible means of artificial recharge.

Availability of Water from Limestone and Dolomite Aquifers in Southwest Ohio and the Relation of Water Quality to the Regional Flow System

Description: Abstracts: The largest ground-water supplies from the 150 to 450-foot thick carbonate-rock aquifer in southwest Ohio are available in a 2,800 square-mile area on the crest and eastern flank of the Cincinnati arch. Well production in the high-yield area is mainly from the Newburg zone, a permeable stratum in the lower part of the Bass Island group. A structure contour map on the top of the Lockport Dolomite shows that the Newburg zone conforms to the configuration of the Cincinnati arch. The chemical quality of the water in the consolidated-rock aquifers is intimately related to the regional flow system, and undergoes a progressive change from a calcium bicarbonate-type in recharge areas to a calcium sulfate-type in areas of natural discharge.

Brief History of Measurement Systems: with a Chart of the Modernized Metric System

Description: Pamphlet issued by the United States National Bureau of Standards providing an overview of the English system of measurement used in the United States and of the metric system. The internal pages of the pamphlet contain a chart labeled "The Modernized Metric System" which includes tables of common conversions and a chart of the seven base units: meter/length, kilogram/mass, second/time, ampere/electric current, kelvin/temperature, mole/amount of substance, and candela/luminous intensity, as well as two supplementary units: radian/plane angle and steradian/solid angle. There is also a graphic representation of yards versus meters in ruler form at the bottom.

Coal Surface Mining Reclamation Costs: Appalachian and Midwestern Coal Supply Districts

Description: Report issued by the U.S. Bureau of Mines discussing costs of strip mining reclamation. As stated in the introduction, "the Bureau of Mines has undertaken this study to determine, as accurately as possible, the actual costs of reclaiming strip mined land in conjunction with active mining operations" (p. 2). This report includes tables, illustrations, and photographs.

Condition Survey: Altus Air Force Base, Oklahoma

Description: "The purpose of this report is to present the results of a condition survey performed at Altus Air Force Base (AAFB), Oklahoma, during 14-17 May 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).

Condition Survey: Biggs Army Airfield, Fort Bliss, Texas

Description: "The purpose of this report is to present the results of an inspection performed at Biggs Army Airfield (BAAF), Fort Bliss, Texas, during January 1972. The inspection was limited to visual observations, and no tests were conducted on any of the pavement facilities. A layout of the airfield is shown in plate 1" (p. 1).
