The Lambton Community Health Study group heads to Ottawa Wednesday to formally ask for federal funding.
$4.8-million is needed to complete phase 3 and $1.76-million is being sought over the next five years from the federal government.
The group has received $1.4 million in funding from the Sarnia-Lambton Environmental Association, but Chair of the Health Study Board, Anne-Marie Gillis, says funding from the feds and province is vital.

The study is to determine if Sarnia area industry is having any impact on the health of residents.
The group will meet with officials from Health Canada, the Ministry of Health, and MP Pat Davidson.
