Lake Fork Watershed - Dinero Complex Remediation. The NRM was
successful in procuring funds through the Clean Water Act Section 319
Nonpoint Source Pollution prevention program, to design and implement
stormwater run-on/runoff control features to a series of mine waste piles
leaching metals contaminants to the Lake Fork watershed. The process
has involved the completion of a multi-tired grant procurement process
including a series of response for proposals, public presentations and
threatened and endangered species act compliance issues. Once
completed, the NRM has partnered with the Bureau of Land Management
and the Division of Minerals and Geology to combine funding sources in
order to complete a mine waste removal strategy. This process has
involved preliminary engineering evaluation of the piles material and
repository area characteristics in order to determine if waste removal is a
feasible alternative. The NRM was then responsible for completing and
documenting an Engineered Early Action Compliance effort for community
review and response, in addition to the production of competitive bid
documentation and review. Once the remedy is completed (anticipated
Fall, 2002), the NRM is responsible for construction completion
documentation as well as 5 year monitoring and compliance.

.

AQUAFIX Pilot Study Implementation. The Bureau of Land
Management pursued the installation of an AQUAFIX@ in-situ treatment
unit for the Dinero adit within the Sugarloaf mining district. This in-situ
treatment is a lime (calcium oxide) reagent reaction with acid mine waters
that is flow driven in regards to release rate. The BLM requested that
NRM help install, maintain and sample the pilot system for the 4-month
duration of the study.

Forage Bioaccumulation Investigation. The U.S. Environmental
Protection Agency in coordination with the Emergency Response Team
has been evaluation the fate, transport and bioaccumulation of California
Gulch fluvial tailings related metals within what is termed 'the 11 mile
reach' of fluvial tailings deposition within the Arkansas River Corridor. The
NRM was tasked to create exclusion areas for plants to be able to inhabit
and grow without the possible loss to wildlife and livestock, thus allowing
for uptake and depuration in plant tissues. The NRM maintained the
exclosures as well as documented the conditions of the plant
assemblages. This effort was completed by the collection of the plants for
metals content after the growing season was complete.

.

Arkansas River Water Quality and Sample Collection. The Colorado
Division of Wildlife has been responsible for the continued monitoring and
evaluation of the Upper Arkansas Watershed water quality as part of an
interagency agreement with the Bureau of Reclamation. The CDOW
requested that NRM complete the sampling and on-site water quality
