Moreover, surface water regimes also represent stark differences in
precipitation patterns from eastern to western states, which is why
water allocation in the United States has a stark water right spatial
pattern. Although surface water allocation doctrines are more
complicated at the state level than the following figure suggests
(Figure 1), it effectively represents this trend. Descriptions of surface
water allocation doctrines are provided in Table 1.

States.

States.

Surface water allocation doctrines can affect the potential
development of MAR projects if a water right is required to replenish
or store water in aquifers, although some states will grant winter
month water rights when demand is low and flows are high.
As technology and population increased, along with our
understanding of the hydrologic cycle, integrated management
approaches have appeared throughout the country, however most
states follow specific groundwater allocation doctrines. Similar to
surface water doctrines, groundwater rights (Figure 2; Table 2) are
complex and have developed over time. Moreover, MAR practitioners
intending to recover stored water may find it difficult to obtain a
permit for extraction. States may allow recovery of only a percentage
of stored water, requiring the applicant to 'bank' the remaining, or
restrict extraction of water on a seasonal basis.

act of replenishing aquifers, while ASR includes storing water for
later use. The USEPA regulates all projects injecting non-hazardous
fluids into or near underground sources of drinking water as Class
V injection wells within the scope of the Underground Injection
Control (UIC) program. The UIC program is a measure to protect
contamination of underground sources of drinking water. Although
federal code has been designed by the USEPA, states may apply for
primacy, which gives states the power to implement and enforce
the program, with the caveat that enforcement must meet or exceed
federal regulations. Federal enforcement of the UIC program would
appear to provide consistency among states; however, the USEPA
maintains 10 regional offices that are responsible for several states
(Figure 3), yet each region may enforce different regulations and
guidelines. For example, the point of compliance for injection wells
may be located at the wellhead, a designated distance from the
wellhead, or at the outer edge of the injected water.

The federal role and MAR
The federal enforcement of MAR deals mainly in water quality.
The United States Environmental Protection Agency (USEPA)
separates MAR into two categories: artificial recharge (AR) and
aquifer storage and recovery (ASR). The USEPA defines AR as the
