THM-precursors should this plant become established in the
Occoquan Reservoir. It was found that the Occoquan Reservoir
could support hydrilla. Three sources of THM-precursors were
found to result from hydrilla. These included: 1)
extracellular products (ECP) from hydrilla itself; 2) ECP
from periphyton that colonized the hydrilla; and 3) decay
products from hydrilla. This study projected aa potential
increase in THMFP of 23 ug/L should hydrilla become established
in the Occoquan. The current level of THMFP in the
H reservoir is approximately l,OOO ug/L.
