Sanitary Sewer Overflows and Emergency Room Visits for Gastrointestinal Illness: Analysis of Massachusetts Data, 2006-2007.

ABSTRACT: BACKGROUND:Sanitary sewer overflows (SSOs) occur when untreated sewage is discharged into water sources before reaching the treatment facility, potentially contaminating the water source with gastrointestinal pathogens. OBJECTIVES:The objective of this paper is to assess associations between SSO events and rates of gastrointestinal (GI) illness in Massachusetts.
