ABSTRACT
The information presented in this chapter covers various topics related to the operation, maintenance, and troubleshooting of a pond, including control testing, safety, and optimizing operations. Much that has been written on these topics in the past 30 years remains valuable but may not be readily available. This chapter summarizes much of that information and brings it up to date. It introduces the basic tools used to monitor an operating pond treatment system and provides guidance when the system does not seem to be functioning as designed (USEPA, 2011).
