This book was released on 1995 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ecological Studies Team (EST) of ESH-20 at Los Alamos National Laboratory (LANL) has collected samples from the stream within Sandia Canyon since the summer of 1990. These field studies gather water quality measurements and collect aquatic macroinvertebrates from permanent sampling sites. Reports by Bennett (1994) and Cross (1994) discuss previous EST aquatic studies in Sandia Canyon. This report updates and expands those findings. EST collected water quality data and aquatic macroinvertebrates at five permanent stations within the canyon from November 1993 through October 1994. The two upstream stations are located below outfalls that discharge industrial and sanitary waste effluent into the stream, thereby maintaining year-round flow. Some water quality parameters are different at the first three stations from those expected of natural streams in the area, indicating degraded water quality due to effluent discharges. The aquatic habitat at the upper stations has also been degraded by sedimentation and channelization. The macroinvertebrate communities at these stations are characterized by low diversities and unstable communities. In contrast, the two downstream stations appear to be in a zone of recovery, where water quality parameters more closely resemble those found in natural streams of the area. The two lower stations have increased macroinvertebrate diversity and stable communities, further indications of downstream water quality improvement.

Book excerpt: In the summer of 1990, an accidental spill from the TA-3 Power Plant Environment Tank released more than 3,785 liters of sulfuric acid into upper Sandia Canyon. The Biological Resource Evaluation Team (BRET) of EM-8 at Los Alamos National Laboratory (LANL) has collected aquatic samples from the stream within Sandia Canyon since then. These field studies gather water quality measurements and collect macroinvertebrates from permanent sampling sites. An earlier report by Bennett (1994) discusses previous BRET aquatic studies in Sandia Canyon. This report updates and expands Bennett's initial findings. During 1993, BRET collected water quality data and aquatic macroinvertebrates at five permanent stations within the canyon. The substrates of the upper three stations are largely sands and silts while the substrates of the two lower stations are largely rock and cobbles. The two upstream stations are located near outfalls that discharge industrial and sanitary waste effluent. The third station is within a natural cattail marsh, approximately 0.4 km (0.25 mi) downstream from Stations SC1 and SC2. Water quality parameters are slightly different at these first three stations from those expected of natural streams, suggesting slightly degraded water quality. Correspondingly, the macroinvertebrate communities at these stations are characterized by low diversities and poorly-developed community structures. The two downstream stations appear to be in a zone of recovery, where water quality parameters more closely resemble those found in natural streams of the area. Macroinvertebrate diversity increases and community structure becomes more complex at the two lower stations, which are further indications of improved water quality downstream.

This book was released on 2008 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spring ecosystems in arid regions are oftentimes the only permanent water source in the uplands and provide essential habitat for a myriad of aquatic and terrestrial organisms (Erman 2002); they are essentially aquatic islands in a sea of desert (Thompson et al 2002) . Riparian areas adjacent to springs can provide habitat to up to 75% of the available species diversity in arid regions (Shepard 1993). Spring ecosystems have evolved within a narrow set of environmental conditions strictly dependent on groundwater discharge (Shepard 19 93). Discharge of springs within Bighorn Canyon National Recreation Area (BICA) has been found to be dependent on snowmelt-based groundwater reaching outflows as recently as weeks after melting, to as long as years after (D. Schmitz, pers. comm.). The mosaic of microhabitats in springs is largely due to stable, long-term flow rates (Perla & Stevens 2003), and perennial discharg e has been linked to diverse, unique and often endemic flora and fauna (Myers 1995, Sada and Vinyard 2002). Aquatic macroinvertebrates can make up a substantial proportion of spring biodiversity. Aquatic species in spring ecosystems can display a high degree of endemism, often evolving to subtle cues in water chemistry (Arsufi 1993, Heino et al. 2003; Sada et al . 2005). Macroinvertebrate populations in springs of the Great Basin, Sierra Nevada, and Colorado Plat eau are known to support endemic aquatic macroinvertebrates (Erman 2002; Hershler and Sa da 2002; Sada and Herbst 2001). An initial survey of Great Basin Springs reported four new species of aquatic invertebrates (Myers 1995). A new species of the springsnail, Pyrgalopsis (the only species reported east of the continental divide) has recently been found in a Missouri River (Montana) spring (Hershler and Gustafson 2002). Even though most spring locations in BICA have been documented on USGS topographic maps, there has been no documentation of aquatic fauna occurring within these ecosystems. Spring flora and fauna in BICA have only been investigated for occurrence of rare riparian and wetland plants (ex.Sullivantia hapemanii var. hapemanii) (Heidel and Fertig 2000). Therefore, a survey of spring fauna will substantially increase the known BICA species and document potentially rare, endemic or endangered species. Surveys in this area will fill data gaps, serve as a reference point for change detection, provide a baseline necessary for evaluating the rarity of different spring ecosystem types, and form an understanding o biological diversity and integrity at the local and ecoregional level. Many spring species have narrow environmental ranges (specialists) and therefore are susceptible to changes in water chemistry and habitat quality Our main objectives for this study include 1) an initial aquatic invertebrate faunal survey and bioassessment of targeted perennial BICA springs, 2) determining the environmental factors that determine biointegprovide a sampling scheme and identify indicator measures (species richness, abundance, target species (i.e. endemics, etc.) with which to monitor spring diversity and biointegrity in the future. Achieving our objectives, especially the third, will allow park managers to monitor the status and changes of aquatic macroinvertebrate indicators over time within BICA springs. This process can be repeated every five years for any proposed spring-type monitoring protocol: an impaired (cattle or human impacted) sample and a reference (pristine) condition sample from each spring type
