reflecting the leading regional development communities. The map shows that TBAs represent approximately 42 % of the continental area and 30 % of the population. Finally, a brief review of current international law, specific bi- or multilateral treaties, and TBA management practice in Africa reveals...
Maps responding to these pillars were developed and combined to create a composite MAR feasibility map. Results show that 18% of the continental area falls into the low feasibility class, 73% into the moderate feasibility class, and 7% into the high feasibility class. The feasibility map was ...
Lastly, to prevent cluttering and enhance practicality, we constructed two base map polygons, each enclosing areas dominated either by mesas or knobs. This approach allowed for an efficient and clear representation of these dense features on the geomorphologic map. The morphologic maps in Figs. 2...

The population served by groundwater from the GLAC was estimated using two datasets: a map of domestic well locations and populations served in the U.S., and a compilation of public water-supply systems and populations served in the glaciated U.S. from the water-use database. Water-quality...
Although this is probably the highest resolution for water sampling in aquifers of that depths reported to date, it is obviously not sufficient to record pH profiles at the mm range, which might be necessary to map LDET in situ. Moreover, pH profiles could also not be determined from fresh...

Fig. 1. Map showing sampling locations, combined Ra (226Ra + 228Ra) concentrations and estimated mean groundwater ages. Areas without grid cells are too saline for potability. Much of the recharge in the regionally unconfined area discharges to streams through local flow systems that are no mo...
