The fine-grained nature of the \u003cbr\u003ealluvial matrix creates a highly heterogeneous environment, \u003cbr\u003ewhich adds to the difficulty of characterizing the flow of \u003cbr\u003egroundwater and the fate of aqueous constituents of concern. \u003cbr\u003eThe analysis of the groundwater geochemical data collected \u003cbr\u003ein October 2009 provides evidence that is used to identify \u003cbr\u003efour groundwater flow paths and their extent in the aquifer \u003cbr\u003eand indicates the dominant attenuation processes for the \u003cbr\u003econstituents of concern.\u003cbr\u003eThe extent and interaction of groundwater flow paths \u003cbr\u003ewere delineated by the major ion concentrations and their \u003cbr\u003erelations to each other. Four areas of groundwater recharge \u003cbr\u003eto the study area were identified based on groundwater \u003cbr\u003eelevations, hydrogeologic characteristics, and geochemical \u003cbr\u003eand isotopic evidence. One source of recharge enters the study \u003cbr\u003earea from the saturated alluvial deposits underlying the South \u003cbr\u003eFork of the Puerco River to the north of the study area. A \u003cbr\u003esecond source of recharge is shown to originate from a leaky \u003cbr\u003ecistern containing production water from the San AndresGlorieta aquifer. The other two sources of recharge are shown \u003cbr\u003eto enter the study area from the south: one from an arroyo \u003cbr\u003evalley draining an area to the south and one from hill-front \u003cbr\u003erecharge that passes under the reported release of perchlorate \u003cbr\u003eand explosive constituents. The spatial extent and interaction \u003cbr\u003eof groundwater originating from these various sources along \u003cbr\u003eidentified flow paths affect the persistence and attenuation of \u003cbr\u003econstituents of concern","brand":"ReadCycle","offers":[{"title":"Default Title","offer_id":47180451610864,"sku":"2940148903628","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940148903628_p0.jpg?v=1763709713","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940148903628","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
