Chapter 8
Checklists
Checklists facilitate the implementation of the site well array O&M plan by providing site personnel with
concrete tasks and schedules. Checklists for the following may be found in Appendix D.
8-1 Type and Frequency of Data to be Collected
Checklists should include daily and totalized flows, pressure per well, and other data (pH, drawdown).
Consult Chapter 5 for frequencies.
8-2 Well Maintenance Log
Table 8-1 lists the recommended information to be logged during a PM treatment event.
Table 8-1. PM Treatment Log Items
Data types
Description
Physical properties
Well identification and diameter, depth to screen, screen interval, total
depth
Remediation measures
Type and amount of chemical used, surging method and times
Related measurements
Periodically and before and after remediation --
Amount and identification of sedimentation
Flow
Well drawdown
Piezometer drawdowns
Power data and notations on instrumentation
Notes on repairs and
Modifications to the well structure and all equipment data
replacements
Related comments
All potentially pertinent information (weather, delays, equipment
problems, discussions over methods, change orders)
Itemization of costs
For budgeting and future reference.
8-3 O&M Calculation Work Sheet
Specific formula calculation sheets should be provided, specific to the wells to be treated. See Section 6-1
and Appendix C for chemical and treatment choice information.
8-4 Other Records
a. Field data sheets. As discussed in Chapter 2, drawdown and flow sheets should be developed
for routine field data collection and should include all relevant data columns. A variety of examples exist
from text, government, and commercial sources.
b. Cost-effectiveness calculation spreadsheets. Sutherland, Howsam, and Morris (1994) provides
cost-effectiveness work sheets and spreadsheets adaptable for HTRW site use.
c. Work orders. Most organized sites generate work orders for activities such as PM well
treatment or equipment repair. These may be paper forms or generated in software maintenance
management systems.
