CREW LABORATORIES
The Center for Restoration of Ecosystems and Watersheds
consists of a complex of laboratories located in Carson
Engineering Center. These laboratories focus on three
related research areas: Environmental Biogeochemistry,
Environmental Microbiology and Environmental Analysis.
The Environmental Biogeochemistry laboratories (S9/S10
complex and S7) focus on inorganic and organic analyses
of natural waters, soils and sediments and are used
extensively for undergraduate and graduate research
activities in wetlands science, ecological engineering
and ecosystem biogeochemistry/ecology. These labs
are also used for demonstration projects and activities
in ES4324/ES5324 Environmental Biology and Ecology,
ES2323 Environmental Science II and CE4903/ES4913
Environmental Capstone Experience.
The Environmental Microbiology laboratory (S22) serves
CEES as both a general environmental microbiology
research facility as well as a teaching facility for
CE 4234 Applied Environmental Microbiology, CE 5624
Biological Design, and ENGR 3510.018 WERC Environmental
Design.
The Environmental Analysis laboratory (S17 complex)
is equipped with state-of-art analytical instrumentation
for the analysis of organic chemicals analytes (volatiles,
semivolatiles, volatile fatty acids), inorganic chemicals
analytes (anions, cations, and metal analyses) and
other water quality parameters. This laboratory contains
many of the basic research/laboratory teaching chemicals
and supplies as well as a variety of environmental
analysis equipment.
The following list provides an example of equipment
included in CREW laboratories: 6-gas chromatographs
(2-NPD, 2-ECD/FID, 2-MS) with autosamplers, auto-headspace
analyzer, thermo-desorber, and purge-and-trap units;
5-ion chromatographs (2-DX300 for anion/VFA analysis,
1-DX90 for anion/cation analysis, 1-MetroOhm for anion/cation
analysis) with autosamplers, electrolytic suppressor;
2- HPLCs with UV, fluorescence, conductivity, PE detectors;
TrAAcs 800 continuous flow analysis system with linear
autosampler; 2- PE5100 atomic absorption spectrophotometers
with flame, furnace and hydride cold vapor generator
capabilities; 2- Beckman DU-65 scanning UV-Vis spectrophotometers;

system 20; 1-Tecator 1009 digestion system 12; 1-anaerobic
glove box; 3-bench-top centrifuges; 3-floor centrifuges;
1-EPI fluorescence microscope; and 1-phase-light microscope.
Specialized equipment for microbial surface thermodynamics
include: 1-Lazer Zee Meter with CCD; 1-luminometer;
1-goniometer with CCD; 1-micro-capillary electrophoresis
with CCD; 1-electrolytic respirometer; 1-gyrotory
water bath and 1-ATP analyzer. Specialized equipment
for field analysis include: 3-YSI6000 multiparameter
water quality units; 1-in situ tracer sonde; 2-SonTek
acoustic Doppler velocimeters; 5-soil probes/collection
units; 1-GTS-210 Electronic Total Station; 1-Trimble
