Shellfish Growing Area Water Quality Checklist [FREE PDF]

Shellfish growing area water quality monitoring is a federally and state-mandated requirement under the FDA National Shellfish Sanitation Program (NSSP) and EPA NPDES permit regulations, designed to protect public health by ensuring shellfish are harvested from waters free of pathogens, chemical contaminants, and biotoxins. Compliance with the NSSP Model Ordinance and state shellfish regulations requires systematic, documented water quality testing at certified intervals, including fecal colifor

Site & Environmental Conditions

Document ambient environmental conditions that influence water quality and sampling validity.

  • Is the growing area currently open and approved for harvest according to the state shellfish authority?
  • Has rainfall exceeded the precautionary rainfall threshold (facility-specific SOP) in the past 48 hours?
  • Are there any visible pollution events (sewage overflow, oil sheen, agricultural runoff) in or near the growing area?
  • Has a harmful algal bloom (HAB) or red tide advisory been issued for this region within the past 7 days?
  • Are sampling station markers and GPS coordinates confirmed and matching the approved sampling plan?

Water Sample Collection Procedures

Verify that sample collection follows certified protocols to ensure laboratory result validity.

  • Were samples collected using sterile, certified sample containers approved for microbiological analysis?
  • Was the sample collected at the required depth (typically 1 meter or per approved sampling plan)?
  • Was the sample labeled with station ID, date, time, and sampler initials immediately after collection?
  • Was the sample placed on ice (0-4°C) and will it reach the certified laboratory within 6 hours of collection?
  • Was a field duplicate or blank sample collected for quality assurance purposes?

Fecal Coliform & Microbiological Parameters

Record fecal coliform results and assess compliance with NSSP classification thresholds.

  • Does the most recent fecal coliform result meet the Approved classification standard (median ≤14 MPN/100mL, 90th percentile ≤43 MPN/100mL)?
  • Is the current fecal coliform rolling median within the Approved range based on the last 30 sampling results?
  • Has the certified laboratory report from the previous sampling event been reviewed and filed?
  • Were any fecal coliform exceedances in the past 90 days reported to the state shellfish control authority?
  • Is the laboratory used for fecal coliform analysis currently certified by the state shellfish authority?

Physicochemical Water Quality Parameters

Measure and record key physicochemical parameters affecting shellfish health and regulatory compliance.

  • Is the water temperature within the acceptable range for the species being cultivated?
  • Is the measured pH within the acceptable range of 7.5–8.5 for shellfish cultivation?
  • Is dissolved oxygen (DO) at or above 5.0 mg/L at all monitoring stations?
  • Is the salinity within the acceptable range for the species being cultivated at this site?
  • Is turbidity within acceptable limits and has a turbidity reading been recorded?

Marine Biotoxin & Harmful Algal Bloom Monitoring

Assess biotoxin risk and verify compliance with shellfish biotoxin monitoring and closure requirements.

  • Has the latest paralytic shellfish poison (PSP) monitoring result been reviewed and is it below the action level (80 µg STX eq/100g shellfish tissue)?
  • Has domoic acid (amnesic shellfish poison, ASP) monitoring been conducted and results reviewed within the past 7 days?
  • Is there visual evidence of algal discoloration, foam, or phytoplankton bloom in the growing area water?
  • Has the state biotoxin monitoring program bulletin been checked for this region within the past 48 hours?
  • Are phytoplankton cell count monitoring records from this growing season available and up to date?

Pollution Source & Shoreline Survey

Identify and assess potential pollution sources that may affect growing area water quality classification.

  • Have all known upstream pollution sources (stormwater outfalls, sewage plants, marinas) been surveyed for new or increased activity?
  • Is there any new construction, land disturbance, or agricultural activity near the growing area that was not present at the last survey?
  • Are all vessel sewage systems within the growing area boundary compliant with No Discharge Zone (NDZ) requirements?
  • Have results of this shoreline survey been documented in the growing area pollution source log?
  • Are photographs of any newly observed pollution sources or shoreline changes attached to this record?

Harvest Decision & Regulatory Notification

Document the harvest decision based on water quality findings and complete required regulatory notifications.

  • Based on all water quality results and site conditions, is the growing area approved for harvest today?
  • If harvest is not approved, has the state shellfish control authority been notified within the required timeframe?
  • Have harvest crews and buyers been notified of the current harvest status (open or closed)?
  • Has this completed water quality record been filed and is it accessible for regulatory inspection?
  • Are there any corrective actions, anomalies, or observations requiring follow-up before the next sampling event?
