A sanitary survey is required before an area can be opened or to keep an area opened for the harvest of shellfish.
• Components– Shoreline Survey– 15 sets of water samples per
classification station over a three year period
– Written Report

• Extent of shoreline to be surveyed– Determine boundaries of the survey area
• Survey the study area for pollution sources
• Types of pollution sources: – Man-made active (point source)– Man-made passive (point source)– Marine (both point and non-point)– Natural (both point and non-point)
Initial Determination of Area

Is there any evidence of discharge?How far is source from the water body?Is the pollution source impacting the water body?Is the source direct or indirect?Point or Non-point ?Is it a dry weather or wet weather problem?Determine flow rate.Sample the discharge.Calculate bacterial loading.Map (location by GPS) all sources and record characteristics of each source. Take a picture!
Source Determination

• Sump pumps• Pool discharges• Failing septic systems and/or systems too
close to the water’s edge (50 feet).• Wastewater Treatment Plants• Industrial discharges
Man-made Active
5
Evaluation – Characterize land use - farms, industry, unique uses, etc. Identify drainages and any other types of pollution sources.

• Pipes, roof drains, etc.• Runoff from roads and other hard
surfaces• Storm drains and illegal connections into
the drain pipe• Dumpsites and other Garbage Containers
Man-made Passive
6
Evaluation – Characterize land use and any other types of pollution sources. Can use a Smoke Test or Optical Brightener Test to try to locate the illegal connection).

• Animals – dogs, cows, marine mammals, other wildlife
• Waterfowl
• People
• Marshes, streams & wetlands
Natural
7
Evaluation - Record the presence of wildlife and if possible estimate numbers and types.

• Marinas
• Mooring Fields
• Boats which are large enough to hold a
Marine Sanitary Device.
Marine
8
Evaluation - Evaluate marinas and mooring fields (use a separate form for this).

During shoreline surveys you count only the boats that are large enough to hold an MSD (≥20’)

On smaller boats MSDs can be found located under the center console
