Aquarius 3.0 Shellfish sanitation simulator, rainfall and water quality closure rule evaluator, version 3.0

This project aims to enhance existing protocols for assessing safety measures in shellfish harvesting areas, with a focus on transforming Aquarius 2.0 into Aquarius 3.0 - our next-gen sanitation model and software. The upgrade will enrich our capacity to evaluate sanitation closure rules for conditionally approved shellfish territories. Alongside this, we're integrating a tide-focused program to allow crucial tide metrics to feed into formulas for gauging Adverse Conditions - combing tide and rainfall data. Thus, refining the accuracy of our safety assessments and ensuring consumer safety remains paramount.

Simultaneously, we're also inducting a second sanitation model named "Pearl" that works seamlessly with the Aquarius system. The new offshoot, Aquarius 3.0 will utilize daily rainfall analytics to produce a curated list of days (and their corresponding durations) when shellfish harvesting is viable, simulating open periods under varied hypothetical closure scenarios. Pearl model then dives into this data, harnessing actual fecal coliform samples from the dates within these simulated open periods, demonstrably assessing whether opening these areas for further shellfish harvests could potentially risk consumer safety.


  1. Develop the Pearl model (including beta testing with pre-existing ta from fecal coliform databases) and integrate it into Aquarius 3.0 along with updated components of Aquarius 2.0
  2. Initiate designs of the various modules that will support Aquarius 3.0 and design the final output report components.
  3. Continue to collect input databases for the growing areas in participating states.
  4. Release software instructions for version 3.0, two audio podcasts describing the NSSP and general shellfish sanitation programs, a Flash Video describing the operation of Aquarius v.3.0 program, and a PowerPoint presentation.
