Considerable controversy continues about water availability for and potential impacts of hydraulic fracturing (HF) of hydrocarbon assets on water resources. Our objective was to quantify HF water volume in terms of source, reuse, and disposal, using the Barnett Shale in Texas as a case study. Data were obtained from commercial and state databases, river authorities, groundwater conservation districts, and operators. Cumulative water use from ∼ 18,000 (mostly horizontal) wells since 1981 through 2012 totaled ∼ 170,000 AF (210 Mm(3)); ∼ 26 000 AF (32 Mm(3)) in 2011, representing 32% of Texas HF water use and ∼ 0.2% of 2011 state water consumption. Increase in water use per well by 60% (from 3 to 5 Mgal/well; 0.011-0.019 Mm(3)) since the mid-2000s reflects the near-doubling of horizontal-well lengths (2000-3800 ft), offset by a reduction in water-use intensity by 40% (2000-1200 gal/ft; 2.5-1.5 m(3)/m). Water sources include fresh surface water and groundwater in approximately equal amounts. Produced water amount is inversely related to gas production, exceeds HF water volume, and is mostly disposed in injection wells. Understanding the historical evolution of water use in the longest-producing shale play is invaluable for assessing its water footprint for energy production.

“…Dramatic shifts in community structure and function are predicted if these remaining perennial habitats shift from perennial to intermittent. Predicted global climate change of increased frequency and duration of droughts in the southwestern United States (IPCC 2007a), coupled with the escalating human demands on groundwater and surface water resources, will likely have a detrimental impact on the remaining groundwater-dependent ecosystems in the Great Plains and arid Southwest IPCC 2007b;Bogan and Lytle 2011;Burk and Kallberg 2012). Note: Larvae and pupae of Trichoptera and Diptera were treated as a single taxon.…”

Invertebrate communities of groundwater-dependent refugia with varying hydrology and riparian cover during a supraseasonal drought

Extreme disturbances eliminate aquatic biota and alter community structure and function. During a supraseasonal drought in north-central Texas in the summer and fall 2006, macroinvertebrate communities from persistent groundwater-dependent macrohabitats of varying hydrology and riparian shading were investigated to study their role as invertebrate refugia, and to characterize the taxonomic and functional community structure of benthic assemblages. Ash Creek was the only stream with surface flow within a 35-km radius during the drought. Two perennial and three intermittent stream sites were studied that included perennial riffles, a perennial pool, shaded disconnected pools, and disconnected pools in full sun. Riffles had significantly higher taxa richness, EPT (Ephemeroptera, Plecoptera, and Trichoptera) richness, proportion of lotic taxa, and diversity than other macrohabitats. Macrohabitats were refugia for 106 benthic macroinvertebrate taxa, and perennially flowing habitats contained 19 taxa (17.9% of total taxa) not collected in disconnected pools. Larvae and pupae of caddisflies Marilia spp., Oecetis spp., Helicopsyche spp., and riffle beetle Microcylloepus spp. larvae and adults demonstrated resistance to drought by their presence in shaded disconnected pools without surface flow for over a month. Gathering-collectors were the most dominant and taxonomically diverse functional feeding group (FFG) in all macrohabitats. Scrapers ranked second in dominance in riffles, followed by predators; however, predators were the second most dominant FFG in all pool habitats. Continued overabstraction of groundwater in the region could lead to loss of perennial riffles and pools and extirpation of lotic taxa, such as Lutrochus spp., Mayatrichia spp., and Marilia spp., and dramatically alter community structure and function.Keywords: drought refugia; aquatic insect community; headwater stream; groundwater-dependent ecosystem; perennial stream IntroductionThe north-central region of Texas, with rainfall totaling less than 882 mm annually, is a semiarid ecosystem (NOAA 2012a). The region has many small streams and springs that are important to the maintenance of aquatic diversity and community structure (Brune 2002). The aquatic invertebrates found in these streams are important links between primary producers and secondary consumers in these systems. Because these streams are dependent on groundwater and springs to maintain flow, reductions to these water sources caused by droughts have been recognized as important forces shaping invertebrate assemblages in streams (Grimm and Fisher 1989;Dudley et al. 1990;Boulton and Lake 1992a;Stanley and Fisher 1992). Lake (2003) distinguished between two types of droughts: seasonal and supraseasonal. Organisms in streams subjected to predictable seasonal droughts *Corresponding author.

However, supraseasonal droughts cannot be foreseen and build gradu...
