This facility appears to be well run and maintained. The staff continues to manage several engineering
design issues and equipment problems. The majority of the damages that occurred after Hurricane
Florence have been repaired and the UV disinfection system is back online. Envirochem in Wilmingtor
is still being used for lab analyses and Triple S is the currently contractor for sludge handling and
disposal.
