(DAILY?)

  3. Market # 3:Ballast Water Quality Validation 100 75 50 25 0 Discharge XYZ 35 % EC50 Level: Control 100% 50% 25% 12.5% 6.25% Our live cultures and test cartridges are the only aquatic live species that are ready to use for testing and verification of the toxicity of ballast water treatment systems and discharges. Both freshwater and marine water samples can be tested. The test cartridges contain plankton, called dinoflagellates, found in 85% of the world’s oceans. The ASTM E1924 test method is a ready-to-implement, live species toxicity test, that can move shipboard to provide quantifiable and repeatable test results. These sensitive organisms are a perfect answer to rapidly determine negative effects of toxic substances.

  4. Water Quality TestingPoint Source Driven Project (needs assessment) Water Testing Laboratory More tests Water to be tested Chemical Instrument Data Adverse Effect? Physical Response ? Integrated Findings “Effluent Centric” • Limited # of samples • Turnaround time not usually tied to near term actions • Expenses paid by permit holders (mostly private companies)

  5. Rapid CharacterizationAdvantages Chemical Instrument Data Physical Paradigm Shift: Early Assessment of Effects = Focus and $ Saved Water Project (needs assessment) Water Testing Laboratory More tests Water to be tested Adverse Effect? Adverse Effect? Response ? Integrated Findings The use and adoption of rapid test methods determines where and how much future testing or treatments should be done. $
