Background information and definitions
Untreated sewage reaching the marine environment can impact subtidal benthic invertebrates through the introduction of bacteria, excess nutrients, toxic substances and solid particles, and through changes in salinity (McGann et al. 2003). Limiting, ceasing or prohibiting the dumping of untreated sewage in an area may benefit subtidal benthic invertebrates by reducing or stopping the source of pollution and allowing communities to potentially recover over time (Bustamante et al. 2012).
