Aquifer Protection Program
Aquifer Protection Program (APP)

Purpose: The purpose of having an Aquifer Protection
Program would be to essentially protect those aquifer
from potential contamination and/or activities that affect
either the water quality or water supply.

Contamination as an issue: Contamination of water
supplies has been an issue for the Navajo Nation in
areas with a high density population, septic systems that
fall, illegal septage disposal, illegal open trash dumps,
that begin to first impact shallow aquifer.

Aquifer Protection Program would: Therefore, such a
program would monitor and protect aquifer by directly
addressing the issues with all potential sources of
contaminants. This program would be both technically
and physically feasible by following existing regulatory
Related Work that has already been done to support APP: The work necessary to make the program successful include the
identification of susceptible or high risk areas to contamination that has already been completed through a Susceptibility Assessment for
each regulated public water supply well. The results of this type of assessment include a contaminant source inventory map with the
location of the public water supply well and a half-mile radius that includes the potential contaminants of concern.

Aquifer vulnerable determinations: Aquifer or Groundwater vulnerability can then be determined using several factors, including well
construction/aquifer information (total depth, well age, aquifer recharge, hydraulic conductivity, to name a few). To avoid redundancy, a
tracking purpose for each regulatory program would be developed and essentially Groundwater Management Access (GMA) would be an
end result where concerns and priorities area identified within each GMA, of which each groundwater source would meet the *USDW
definition and the aquifers end use would be defined. USDW: Underground Source of Drinking Water
Aquifer Evaluation used to restore or maintain aquifer to safe
and reliable sources:
These types of existing evaluation support
and give the best analysis for aquifer vulnerability which then give
indication to the type of protection afforded to aquifer to existing
and future development, or end uses, on the Navajo Nation.
Continuous groundwater monitoring under this program would
demonstrate the stability of aquifer conditions. Geochemical
characteristic and contaminant concentrations of aquifer (aquifer
characteristics) would show any trends or changes in water
quality overtime (before, during and after) any development or
mining activities. Activities would need to be permitted and any
instability of aquifer conditions would be cause for the business
site lease owner to restore aquifer conditions to baseline or to
Aquifer Protection/Aquifer Water Quality standard.

APP Goal: The goal is to protect public health and such a
program would be coupled with a public education program for
each GMA that provides information relevant to any health
hazards of potential contaminant sources in each aquifer on the
Navajo Nation.
