Sanitary sewer overflow (SSO): sewage spills from a sewer meant to carry sewage separately from rainwater. Combined sewer overflow (CSO): sewage mixed with rainwater spills from a shared sewer system. Cyanobacteria (harmful blue-green algae) can make water unfit for contact; the issuing authority decides when its advisory ends.
