area can be opened or to keep an area
opened for the harvest of shellfish.

Water Quality and Shellfish Areas

  1. 1. Sanitary Surveys By Neil Churchill
  2. 2. 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 2
  3. 3. • 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 3
  4. 4. 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 4
  5. 5. • 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.
  6. 6. • 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).
  7. 7. • 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.
  8. 8. • 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).
