To provide the client with defensible, comprehensive and innovative solutions,
to conduct the work with integrity, attention to detail and value-added effort,
giving due consideration to budget and time constraints, yet maintaining a
very high standard of quality in work products for a very reasonable cost.

Navajo Mine Report [May, 2005] - This study, undertaken
for the National Academy of Sciences, examines the weight of evidence (or lack thereof)
regarding the mine operator's claims about the lack of environmental impacts from
fly ash disposal at the mine, located near Farmington, northwestern New Mexico).
Evaluation of Critical Management Areas (CMAs)
[March, 2005] - This report documents the development and application of a groundwater modeling methodology for
assessing the potential for the creation of CMAs in the Middle Rio Grande Valley, New Mexico. The work is important
with respect to the client's ability to fully utilize and protect permitted water rights.
Technical Review of a Geohydrological Report
[February, 2003] - The report was produced to support
the findings concerning the adequacy of a 100-year water supply for a proposed subdivision. The review notes that the "cook-book" formulas used in the Land Development Code for calculating water availability
were only appropriate for simple, small scale, shallow groundwater systems, not the complex,
heterogeneous, faulted, multi-layer system commonly encountered. Analysis of the output
produced by the groundwater model demonstrates how inappropriately-assigned model parameters
and inadequate quality assurance checking of results can lead to nonsensical (hydrologically
impossible) results and erroneous conclusions.
Evaluation of Water Reuse Alternatives
[November, 2001] - This report documents the development and appli- cation of a methodology for assessing hydrologic impacts resulting
from discharge of treated wastewater into infiltration galleries or via deep-well injection into the saturated zone.
The analysis procedure was developed to simultaneously take into consideration issues of importantance
to water managers, regulators, citizen and business stakeholders. The results
demonstrate the importance of removing the dependence among the performance measures in order to obtain
meaningful relative rankings among alternative scenarios.
Evaluation of River-Aquifer Interaction
[March, 2000] -- This report documents the model calibration effort for a large-scale, short-duration aquifer test conducted
using municipal supply wells along the Rio Grande in central New Mexico.
Liberal use of expert judgement was necessary in constructing static (recovering) water levels due to insufficient recovery time between pump shut-off and the start of the test. Sensitivity analyses were performed to quantify the uncertainty in the calibrated model parameters and to identify which parameters have the greater impact on river depletions. The lessons learned through the analysis process attest to the importance of carefully designing and conducting a large-scale, multi-well aquifer test.
