Major aquifers, well yields, estimated natural recharge, estimated water in storage, number of index wells and date of last water-level sweep are shown in Table 3.13-5. Figure 3.13-7 shows aquifer flow direction and water-level change between 1990-1991 and 2003-2004.
Each Federal agency should make achieving environmental justice part of its mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of its programs, policies, and activities on minority populations and low-income populations.
This technical memorandum was prepared to summarize results of drilling, construction, and testing at hydrologic test well DHRES-09. The well was installed to characterize hydrogeologic conditions in the deep groundwater system west of the Concentrator Fault and east of the Main Fault, and to provide a monitoring point for the deep groundwater system during on-going dewatering operations. Monitoring data obtained from DHRES-09 have been incorporated into the RCM hydrologic monitoring program.
Arizona hedgehog cactus survey was conducted on the approximately 1,224-hectare Federal Parcel. The parcel is on the Tonto National Forest east of the Town of Superior. Resolution proposes to obtain the Parcel by way of a land exchange.
This report provides chemical, physical, mineralogical, and microbiological procedures for the analysis of coal overburdens and the resultant minesoils. These step-by-step methods identify and measure rock and soil properties that influence advance planning, mining efficiency, post-mining land and water quality and long range land use.
This action is necessary to ensure that National Forest System roads provide for public uses of National Forest System lands; provide for safe public access and travel; allow for economical and efficient management; to the extent practicable, begin to reverse adverse ecological impacts associated with roads; and meet all other current and future land and resource management objectives.
Topics include land use, demographics, specific industry sectors, the role of non-labor income, the wildland-urban interface, the role of amenities in economic development, and payments to county governments from federal lands.
These maps show an estimate of the likelihood of earthquake ground motions, based on a probabilistic seismic hazard analysis. Such analysis incorporates seismic and geologic information to consider the probability of all possible damaging earthquakes, calculates the potential range of ground motions for each potential earthquake, and arrives at a level of ground shaking that has a given probability, using the formulation first developed by Cornell (1968).
