Groundwater Level Status Report for Fiscal Year 2006 Los Alamos National Laboratory

TL;DR: The status of groundwater level monitoring at Los Alamos National Laboratory in Fiscal Year 2006 is provided in this paper, where pressure transducers were installed in 132 monitoring wells for continuous monitoring of groundwater levels.
Abstract: The status of groundwater level monitoring at Los Alamos National Laboratory in Fiscal Year 2006 is provided in this report. The Groundwater Level Monitoring Project was instituted in 2005 for providing a framework for the collection and processing of quality controlled groundwater level data. This report summarizes groundwater level data for 158 monitoring wells, including 43 regional aquifer wells, 23 intermediate wells, and 92 alluvial wells. Pressure transducers were installed in 132 monitoring wells for continuous monitoring of groundwater levels. Time-series hydrographs of groundwater level data are presented along with pertinent construction and location information for each well.

Summary

  • In view of the observed mean weight loss at 6-months being >10% TBWL in the two previously referenced real-world studies, one would expect to have observed a statistically significant and clinically meaningful reduction in obesity related metabolic comorbidities.
  • This international multicenter study of 112 consecutive patients who underwent endoscopic sleeve gastroplasty for treatment of obesity demonstrates consistent efficacy and safety of the procedure across the study centers, and is furthermore consistent with reported outcomes in the published literature.
  • The adverse event rate associated with ESG may be acceptable to many patients in light of the superior weight loss as compared with HIDLT.
  • The technique used was the same as that described by Sartoretto et al. [16] using the OverStitch fullthickness endoscopic suturing system (Apollo Endosurgery, Austin, Texas, USA).
  • Tate CM, Geliebter A. Intragastric Balloon treatment for obesity: review of recent studies.
  • 10,44 Consistent with reductions in visceral adiposity, GMD resulted in significant reductions in serum and liver lipid content and size (Fig. 4).
  • The authors previously published works have investigated an alternative to excision, devitalization of the gastric mucosa, in an obese rat and porcine model [12, 13].

TL;DR: This paper presents a method that utilizes a simple analytical modeling approach for analysis of a long-term water level record utilizing an inverse modeling approach and provides guidance for the development of more complicated models requiring detailed specification of the aquifer heterogeneity.
Abstract: Identification of the pumping influences at monitoring wells caused by spatially and temporally variable water supply pumping can be a challenging, yet an important hydrogeological task. The information that can be obtained can be critical for conceptualization of the hydrogeological conditions and indications of the zone of influence of the individual pumping wells. However, the pumping influences are often intermittent and small in magnitude with variable production rates from multiple pumping wells. While these difficulties may support an inclination to abandon the existing dataset and conduct a dedicated cross-hole pumping test, that option can be challenging and expensive to coordinate and execute. This paper presents a method that utilizes a simple analytical modeling approach for analysis of a long-term water level record utilizing an inverse modeling approach. The methodology allows the identification of pumping wells influencing the water level fluctuations. Thus, the analysis provides an efficient and cost-effective alternative to designed and coordinated cross-hole pumping tests. We apply this method on a dataset from the Los Alamos National Laboratory site. Our analysis also provides (1) an evaluation of the information content of the transient water level data; (2) indications of potential structures of the aquifer heterogeneity inhibiting or promoting pressure propagation; and (3) guidance for the development of more complicated models requiring detailed specification of the aquifer heterogeneity.

The status of groundwater level monitoring at Los Alamos National Laboratory in Fiscal Year 2006 is provided in this report. The Groundwater Level Monitoring Project was instituted in 2005 for providing a framework for the collection and processing of quality controlled groundwater level data. This report summarizes groundwater level data for 158 monitoring wells, including 43 regional aquifer wells, 23 intermediate wells, and 92 alluvial wells. This report presents and describes groundwater level data obtained by Los Alamos National Laboratory ( LANL ) during Fiscal Year ( FY ) 2006 to provide regulatory compliance and to provide other programs at LANL with groundwater level data for modeling and data assessment. This report includes groundwater level data obtained during FY 2006 ( October 1, 2005, through September 30, 2006 ) and, where available, historical data. The groundwater level data are presented on time-series graphs to provide a comprehensive representation of the groundwater level characteristics, to the extent possible with available data. For the alluvial wells, the first graph for each well represents the entire period of record, while the second graph represents FY 2006 to provide better representation of seasonal changes. 2. 0 Description of Groundwater Level Data The Groundwater Level Monitoring ( GWLM ) Project at LANL is conducted under the Quality Assurance Project Plan ( QAPP ) for Groundwater Level Monitoring ( LANL 2006 ) to assure the quality of groundwater level data. The QAPP contains the work processes and the data quality objectives utilized in the GWLM Project. In the following sections, both manual measurements and transducer measurements are shown on the time-series hydrographs. Because hourly transducer measurements are too voluminous to reproduce for most hydrographs, mean daily groundwater levels are shown on the hydrographs in this report. In the following sections, acronyms used to describe groundwater level data include GW data obtained from transducers during groundwater sampling events Trans measurements from transducers installed in a well MP Measurement Port identification in multiple completion wells. Groundwater levels in water supply wells at Los Alamos have been summarized in the series of water supply reports for Los Alamos, e. g., Koch and Rogers ( 2003 ). The previous report in this series, Groundwater Level Status Report for 2005, was issued in May 2006 ( Allen and Koch 2006 ).Â
