   dcterms:title "Depletion of Groundwater in Major U.S. Regional Aquifers"^^xsd:string;
   gcis:hasCaption "(left) Groundwater supplies have been decreasing in the major regional aquifers of the United States over the last century (1900–2000). (right) This decline has accelerated recently (2001–2008) due to persistent droughts in many regions and the lack of adequate surface water storage to meet demands. This decline in groundwater compromises the ability to meet water needs during future droughts and impacts the functioning of groundwater dependent ecosystems (e.g., Kløve et al. 2014{{< tbib '3' '38d66cb7-6270-4fa1-8e12-215ddb0a37c5' >}}). The values shown are net volumetric rates of groundwater depletion (km per year) averaged over each aquifer. Subareas of an aquifer may deplete at faster rates or may be actually recovering. Hatching in the figure represents where the High Plains Aquifer overlies the deep, confined Dakota Aquifer.
