| ANTHROPOGENIC HABITAT MODIFICATION in PEDDER BAY |
 |
Pearson College fronts on the bay on the north side. Modifications to the shoreline have changed the habitat of the bay. The floating docks provide a large substrate for additional growth of biomass. Boats, diesel and gasoline, provide additional hydrocarbon discharge into the bay. Introduction of efficient four stroke engines in recent years have helped to mitigate boat engine pollution.
No Inorganic fertilizers or pesticides are used on the campus, so surface runoff is not an issue. |

Pedder Bay marina docks has a great number of boats which provide a large potential input of hydrocarbons. Chronic oil pollution from bilge systems of boats in marinas such as this provide a continual hazard to marine life. Location of Sewage outfall is not known, although it is believed that it runs at least part way out of the bay. |

The trailer court at Pedder Bay sits on the bank of the estuary . Sewage from this location is pumped seaward and terminates in middle Pedder Bay. Primary sewage treatment only is available. | |||

The Rocky Point DND sewage outfall runs down the shore in a buried pipe, and terminates over 100 meters seaward in the bay. It is presumed that secondary treatment has been done on this effluent. | |||
 |
The bottom of the ocean at the DND Jetty has been dredged to deepen it for ocean going vessels. This is a fixed concrete pier. | |||
