Connecting to the existing Troy system was seen as the most expensive, at $48.5 million; connecting to a new untreated surface water source from the Tomhannock, at $34.4 million; continued filtering of existing village wells plus a remediation system for contaminants at McCaffrey Street, $10.1 million; development of a new village well water sources, at $6.9 million, and continued use of filtering alone at the existing village wells at $6.3 million. Comments on the report will be accepted until Nov. 18.
