Possible Effects of Long-Term Exposure to Arsenic (As):
Skin damage or problems with circulatory systems, and may have increased risk of getting cancer. Read more from the US EPA.

Characteristics of water with excess Iron (Fe):
Rusty color; sediment; metallic taste; reddish or orange staining. Read more from the US EPA.

Possible Effects of Long-Term Exposure to Alpha Particles:
Increased risk of cancer. Read more from the US EPA.

Possible Effects of Long-Term Exposure to Lead210 Particles:
Increased risk of cancer. Read more from the California EPA's Office of Environmental Health Hazard Assessment (PDF).

Possible Effects of Long-Term Exposure to Uranium234:
Increased risk of cancer, kidney toxicity. Read more from the US EPA.

About this data: This data was collected by the US Army Corps of Engineers (USACE) and published by the US Environmental Protection Agency (US EPA) between 1994 and 2000. All raw data displayed on this website is in the public domain. An indication of "NA" for a particular contaminant means that contaminant was not tested for. The limits cited come from US EPA Maximum Contaminant Levels (MCLs). For those contaminants which do not have EPA MCLs (as indicated by a star), the preliminary remediation goals of the USACE availble were used instead. Information about health effects is derived from US government websites, to learn more, click the link next to each one. Please Note: Navajo Nation policy is that livestock-use-only wells are not to be used for human drinking water. Additionally, this website does not contain information about other possible contaminants this water source may have, such as E coli and various bacteria.

Raw Data

"MCL" stands for Maximum Contaminant Level, the highest allowable amount of a given contaminant in public drinking
water, as set by the US EPA. For those contaminants which do not have EPA MCLs (as indicated by a star), the preliminary
remediation goals of the US Army Corps of Engineers were used instead.
