Non-Radioactive Contaminants:
Iron (Fe): Above Limit
Thallium (Th): Above Limit
Radioactive Contaminants:
      Lead210: Above Limit*


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 Thallium (Th):
High levels of Thallium can lead to nerve damage, changes in blood chemistry, irritation and intestinal damage, testicular effects, hair loss, as well as damage to the kidney and liver damage if consumed in high doses of long periods of time. 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).

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.

One comment about this water source so far:

    To whom it may concern;
    I was looking at the return of the navajo bog web site wben i came upon this website about the windmills. However, windmill 8T-518 is about a mile north of my mothers residence. As a child growing up 8T-518 was our main source of drinking, cooking and washing water until up to the time running water was in place around 1999. I’m writing to know more about this and also what can be done for myself and family. Thank you.
