WELLHEAD PROTECTION PROGRAM: 7 Elements
and Duties of the state and local governments and public water
supply agencies. A planning team should consist of an elected
official, fire chief, public works director, system operator,
water customer, and other interested parties. It is important
to take advantage of the knowledge and expertise of members of
the community to design a plan that will best meet the needs of
your community. It is always good to strive for a diverse group.
This element of the program must list all the team members and
a description of their roles and responsibilities.
of the wellhead protection area (WHPA) for each wellhead, based
on reasonably available hydrological and other data. The WHPA
is the area on the surface that overlies that portion of the aquifer
that supplies water to the well. The state mandates using a ten
year total time of travel (TOT) to delineate the WHPA. The map
that shows the WHPA should also show the location of the wells,
water level contours, and municipal boundaries.
of potential contaminant sources within each wellhead protection
area. This provides an assessment of the potential threats to
Source Inventory (CSI) should include a description of the process
used to identify potential sources, a listing of all the potential
sources, and a map which displays all the potential sources of
approaches for wellhead protection, including but not limited
to education and regulatory approaches. These are actions that
are taken to minimize the potential for contamination of the communities'
wells. The plan should include a description of the local management
program, identification of the partnerships or agreements, phasing
of management controls and a time table for program implementation.
plans for public water supply systems, to develop options
to deal with both short and long term loss of the drinking water
supply. The plan should outline the policies and procedures for
the water supply emergency response, and indicating the type and
location of alternate drinking water supplies.
- Proper siting
of new wells to minimize potential contamination. Procedures
should be in place to address the addition of new wells to the
communities supply. The plan should identify the location, proposed
depth, and other descriptive information for all new wells. The
WHPAs should be identified if they are known.
education and participation The public must be involved in
some way during the wellhead protection planning and implementation
process. Having the public involved and educated is a way to help
them own the plan so that they will want to help it succeed.
