Hutchinson-Nickerson are larger than required by the local consumers within that
part of GMD2. In the area of GMD5, if we consider the salt water of the deep
aquifer as a potentially usable portion of the regional groundwater resources, then
the local amounts of water available exceed the requirements of all local
consumers. The weak point in this calculation is lack of balance of the salinity
budget. A balance can be attained only by partial use of the groundwater resources
of the deep aquifer, which will require mixing this water with water of
comparatively low salinity. However, freshwater resources are scarce in GMD5
area, and in the dry season the local water demands by the consumers cannot be
met under current conditions, especially in areas of intensive irrigation. The bright
point in this situation is that northern Stafford County in GMD5 contains two
types of local consumers, farms (especially irrigated) and natural habitat (the
wildlife refuge), with very different needs for water quality.
The initial calculations outlined in preceding paragraphs led the authors to the
development of a proposed IWRM solution, whose details are given in the
following section. This proposed solution must be considered by the regional and
state agencies before developing the next stages, which would include
incorporation of parameters of environmental safety, economy, political aspects,
etc. In subsequent advanced stages of the study program, contemporary research
platforms would be used to provide adequate expert systems and optimization
tools. Some of the issues requiring evaluation are the appropriate timetable of
different operations, gradual development of the project in stages, timetables for
investment of private and public moneys, possible state subsidies to alleviate the
burden on the small local communities, etc.
3.3 Adoption of the Appropriate Solution
Based on application of the IWRM approach, it appears that almost all water
supply needs can be met with water quantities and qualities appropriate to the
specific uses. Actual implementation of the water transport and use changes would
require both investment in infrastructure and modification of existing regulations
and practices. The solution proposed in this section is under initial discussions to
determine the feasibility of its engineering implementation, and the necessary
modifications of decision-making and allocation of appropriate public and private
investments. However, this solution exemplifies the great potential of the IWRM
approach to address issues of environmental quality and water supply needs
through innovative combination of issues and resources.
