Abstract
A implantação de um complexo industrial na reglao de Barcarena, PA, levou as autoridades, a empresa e a comunidade em geral a procederem estudos sobre as características do ecossistema antes do início das atividades industriais. O presente trabalho diz respeito ao estudo sobre o quimismo predominante nas águas subterrâneas e do sistema flúvio-estuarino dessa região.
