water sampling event for the Colorado Department of Public Health and .
Environment. This project involved sampling from over 40 wells in the
Leadville Superfund Site. At the same time the student involved conducted
a ground water extension to the Dye tracer study using the same wells.

Pueblo Board of Water Works: NRM was hired to reestablish a riparian
habitat along the east banks of Columbine Ditch. Columbine Ditch is
property of the Pueblo Board of Water Works. This ditch diverts water
from the western slope over the divide into the Arkansas River water shed
.The project required several students to transplant and water willows.
Transplantation involved the clipping and bundling of willow branches that
were later soaked for 48 hours and buried in the ground. Once they were
planted, the willows were monitored, maintained, and watered three times
a week. NRM will continue this project in summer 2003.

BlM - Fremont Pass Reclamation: For the Bureau of Land
Management, the NRM was responsible for inventorying and evaluating
the nature and extent of erosional sources throughout the length of the
closed portion of Fremont Pass. This project was funded in part by a
grant procured by the U.S. BLM, for which NRM provides grant
administration assistance. These erosional zones had historically been
contributing significant sedimentation to the Arkansas River headwaters
area. NRM surveyed and classified each erosional area by feature and
also implemented a monitoring strategy. Currently the NRM is in the .
phase of providing permit compliance assistance and design strategies for
the control of the erosional areas.

California Gulch Constructed Wetlands Treatment
(Resurrection/Newmont and EPA): Constructed wetlands are finding a
usefulness in the realm of acid mine drainage treatment. They have been
demonstrated as an effective metals-loading treatment system for
compromised waters. NRM implemented a project to undertake and
determine the effectiveness of constructed wetlands as a treatment
alternative for the California Gulch Superfund Site. The NRM is in
partnership with the US EPA and Resurrection/Newmont Mining Co., who
are responsible parties for the Superfund Site. The NRM is currently in
mid-stage of the wetlands assessment by having completed an
assessment of its application, designing the tentative treatment footprint
within the Gulch and by implementing a bench scale test. The bench
scale test will identify the suitable combination of treatments for the
reducing cell component of the treatment wetlands. Upon completion of
the bench test, an in-field pilot study will be designed.

Resurrection/Newmont Operable Unit 8 - Surface Water Sampling:
The NRM was tasked to assist Resurrection/Newmont with their annual
surface water sampling conducted throughout the Operable Unit 8 portion .
