development time considerably.
10. Reassemble, install, and test the pump and in-well instrumentation and return to service.
11. Benchmark biofouling and performance indicators using methods suggested.
12. Clean and make necessary repairs to treatment equipment.
C-3. Treatments for Heavily Impacted Wells
a. While the intended scope of this EP is the maintenance of well system performance, it is recognized
that O&M personnel will usually find themselves in the situation of rehabilitating wells and systems that
have deteriorated in performance. Rehabilitative treatments have many similarities to maintenance
treatments such as the example outlined in paragraph C-2. Such treatments are summarized in Driscoll
(1986), Borch, Smith, and Noble (1993), Cullimore (1993), Smith (1995). One such treatment
summarized in Alford and Cullimore (1999) focuses on HTRW remediation applications.
b. Rehabilitation treatments outlined in these publications typically can be applied using adaptations of
conventional ground water technology equipment. In addition, well rehabilitation has a number of
specialty tool, equipment, supply, and service vendors. An attempt has been made to offer information on
and Internet links to sites on well rehabilitation from the "Groundwater Science" website
<http://www.groundwatersystems.com>.
