Abstract
This project reviewed the ability of hydrilla to release

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.
