Groundwater Level Status Report for Fiscal Year 2007 - Los Alamos National Laboratory
17 Mar 2008-
TL;DR: The status of groundwater level monitoring at Los Alamos National Laboratory in Fiscal Year 2007 is provided in this paper, where pressure transducers were installed in 133 monitoring wells for continuous monitoring of groundwater levels.
Abstract: The status of groundwater level monitoring at Los Alamos National Laboratory in Fiscal Year 2007 is provided in this report. The Groundwater Level Monitoring Project was instituted in 2005 to provide a framework for the collection and processing of quality controlled groundwater level data. This report summarizes groundwater level data for 166 monitoring wells, including 45 regional aquifer wells, 25 intermediate wells, and 96 alluvial wells, and 11 water supply wells. Pressure transducers were installed in 133 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.

1.0 Introduction
- This report includes groundwater level data obtained during FY 2007 (October 1, 2006 , through September 30, 2007) 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 2007 to provide better representation of recent and seasonal changes.
2.0 Description of Groundwater Le vel Data
- Previous reports of groundwater level data at LANL were compiled for the regional aquifer test wells (TWs) by Koch et al. (2004) and for all wells in a submittal to the New Mexico Environment Department in January 2005 (LANL 2005) .
- 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) .
3.38 Test Well 1
- The following sections include additional port and construction information for single and multiple completion intermediate wells at LANL.
- Time-series groundwater level data are shown for each well.
5.0 Groundwater Le vel Data from Alluvial Wells
- Table 5 -1 lists the alluvial wells that were monitored for groundwater levels in FY 2007.
- The table provides the well name, date of completion, well depth, surveyed location coordinates, ground surface elevation, and the screen top and bottom depths for each well.
- In the following alluvial groundwater sections, the first graph for each well represents the entire period of record, while the second graph represents groundwater level data from FY 2007.
- Alluvial groundwater levels respond to snowmelt runoff, storm runoff, and, in some canyons, effluent discharges.

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.
