Selenium Reduction
Department of Interior National Irrigation Water Quality Program (NIWQP) investigations
into problems caused by irrigation drainage in northeastern Utah revealed leakage of
wastewater ponds at the Ashley Valley Wastewater Treatment Facility (Ashley Valley) near
Vernal. The wastewater percolated through Mancos Shale, a selenium-bearing formation, and
out into Ashley Creek, a tributary to the Green River in an area of biological importance
to the endangered razorback sucker. High concentrations of selenium entered the
environment from this source. The USFWS EC Program in Utah played a major role in NIWQP
investigations in northeastern Utah and in assessing the Ashley Creek selenium problem.
The State of Utah and Ashley Valley initiated action when the USFWS threatened prosecution
under the Endangered Species Act due to effects to endangered fish. Ashley Valley and the
State of Utah signed a consent decree to replace the existing lagoon system with a
mechanical treatment facility by February 2001. Ashley Valley has initiated interim
measures aimed at reducing seepage into the selenium-bearing formation by reducing the
number of ponds from five to three. Grants and loans from the State of Utah and a federal
appropriation of $7 million will be used to pay for the project. Salinity control funds
from the U.S. Bureau of Reclamation may also be available for the project. Ashley Valley
has received designs and construction bids for a new facility. Construction will take
approximately 18 months. The load of selenium contributed to the Green River system by
Ashley Creek is about the same as all of the other upstream sources combined. The NIWQP
studies showed that the Ashley Valley wastewater ponds contributed the majority of
selenium into Ashley Creek. Completion of the new facility should eliminate a significant
portion of the selenium problem to endangered fish in northeastern Utah.
Jordan River Habitat Restoration
The Jordan River, located in Salt Lake County Utah, is a highly urbanized and degraded
river that has been dewatered, channelized and polluted. Five Superfund sites located on
the Jordan River have been or are in the process of being remediated. In 1991 the USFWS
received a $2.3 million settlement from the responsible parties of one of the Superfund
sites known as the Sharon Steel Superfund site. The funds were for restoring threatened
and endangered species, migratory birds and wetlands affected by the release of heavy
metals from the site. In 1997, the USFWS embarked on three long term projects to restore
damaged natural resources and restore 274 acres of habitat on the Jordan River. Other
federal, state, municipal and nonprofit organizations including Utah Reclamation
Mitigation and Conservation Commission, U.S. Environmental Protection Agency, U.S. Army
Corps of Engineers, Utah Division of Wildlife Resources, West Jordan City, City of South
Jordan, National Audubon Society, Great Salt Lake Audubon Society, Tree Utah and Trust for
Public Lands have contributed both funds and in-kind services to match the $2.3 million
with $7.4 million for a total of $9.7 million! This partnership of state and federal
agencies and local organizations have begun work on properties acquired for the
restoration project. Efforts are underway to contour highly erodible banks, remove
nonnative invasive vegetation and to plant trees and shrubs which are native and provide
quality habitats for migratory birds. As property values continue to rise, it becomes a
race to acquire the remaining acreage with the secured funds and the USFWS is now looking
for new partners to join the effort to preserve and protect a riparian corridor on the
Jordan River. These projects represent immense planning, negotiating and vision from many
agencies of various jurisdictions as well as nonprofit organizations, municipalities and
private citizens which have come together to make these projects a reality. For more
