The objective of this study was to take advantage of the unique opportunity
afforded by the Information Collection Rule (ICR) Treatment Study database to analyze the data for trends in granular activated carbon (GAC)
effectiveness. The database allows the effects of water quality parameters and plant
design variables on GAC service life to be evaluated. Statistical analysis was conducted
to study the relationships between GAC service life and factors such as geographical
location, raw water quality, GAC type, empty-bed contact times (EBCT), and plant pretreatment.
Two potential products of this study of GAC efficiency trends are: the
development of statistical models that utilities can use to perform desktop GAC treatment
feasibility studies prior to more expensive bench- or pilot-scale testing; and, a tool for
utilities to optimize their current utilization of GAC and reduce treatment costs. In this
paper, the methodology that could be used to evaluate the entire database is demonstrated
for one geographical region.
