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
