The main purposes of EnviroSync are to:
(1) serve as an advocate for the MES-SR community
(2) assess the state of existing SR facilities for MES research on a continuing basis
(3) assess the SR needs of the MES community on a continuing basis
(4) serve as an advisory group to federal agencies concerning the need for new
SR facilities in the MES area
