This presentation shows pictures of unregulated water wells on the Navajo reservation as well as maps of areas across the Navajo Nation where contaminants were detected in the water sources.

30% of Navajo Nation residents lack household access to a public water system. Water consumption from unregulated sources represents a public health concern.

Background 

On August 5, 2015 approximately 3 million gallons of mixed heavy metal liquid waste was released into Cement Creek from the Gold King Mine in Southwestern Colorado. The bright orange color of the waste could be seen as the plume entered the Animas, and then the San Juan River. As the plume passed Kirtland, NM and entered the Navajo Nation, visual tracking was lost. At the Native EH Equity Center, we began to plot available sampling data in an attempt to visualize the plume’s movement in order to determine where metals may have precipitated into the river sediments and floodplains. Results of that interpolation and visualization of data are presented for pH, Al, Fe, and Mn.

Over the following weeks, the Center entered into a Consortium of state universities in an effort to coordinate activities and bring to bear all available resources to understand the future implications of the spill.

The Center for EH Equity plans to work with Navajo colleagues and others in the affected communities to identify potential exposure pathways for future use of the San Juan, and to understand the geochemical, microbiological, and mineralogic properties of the metals and the river to develop a comprehensive understanding of the potential risks that remain for the communities along the river.

Introduction

Less than 1% of the US population lacks household access to a safe and reliable drinking water supply (Navajo Housing Survey, 2007); however, approximately 14% American Indian/Alaska Native homes lack household water supply (USEPA, 2010). For individual tribes such as the Navajo Nation, this frequency can exceed 30% (about 54,000 people).

The Navajo Nation is the site of extensive historical resource extraction. Uranium mining for the Cold War occurred throughout the Navajo Nation and there remains a legacy of more than 1,100 abandoned mine features.

Navajo communities have expressed concerns about the impact of uranium mining and waste on the land, water and human health.

Drinking water is one possible exposure pathway for Navajo Nation residents.

Blue Gap, AZ – The Southwest Research and Information Center and University of New Mexico Civil Engineering Department reported their findings of the presence of dangerous heavy metals in soil and water samplings in the Tachee – Blue Gap community.

The Blue Gap community organized a group of concerned citizens: Tachee  Uranium Concerns Committee/Blue Gap-Tachee Chapter to better understand how metals mixtures at abandoned uranium mine waste sites alter the movement of metals in the environment and also impact health, specifically immune function, DNA damage and repair, and cardiovascular disease in tribal populations.

The Navajo Birth Cohort Study addresses the need to study the multigenerational exposures, to understand the relationship between exposures, birth outcomes, and development key to ensuring that children can develop to their maximum potential.

Window Rock, AZ – This powerpoint presentation was originally presented at the Navajo Nation Museum as an update on the Navajo Birth Cohort Study to the Navajo Nation Institutional Research Review Board on October 21, 2015 in Window Rock, AZ.

The Navajo Birth Cohort Study is a multi-agency prospective study to assess pregnancy outcomes and child development in relation to uranium mining and tailings waste exposures among Navajo mother-infant pairs.
