ETL appeared on Television broadcasts of two news conferences called by John Keane of Trout Unlimited. The news conferences were to publicize the release of the report. A Study of Storm Water Conveyances as Point Sources of Pollution in the East of Hudson Watershed, New York City Drinking Water Supply.

ETL has recently completed an Interlaboratory Validation study. Three laboratories as well as our own performed the Tetramitus Assay on cadmium chloride and 4NQO 4-nitroquinoline-N-oxide and compared the results. This study was undertaken by Drs. Chandler Fulton, Charles Walsh and Oscar Pancorbo from Brandeis University, the University of Pittsburgh and the Massachusetts DEP, respectively.

Preliminary evaluation of the data shows that all laboratories obtained linear dose response curves for both toxicants with an interlaboratory coefficient of variation of 50-60%. Further evaluation will be published in the upcoming ATSDR Report, 2nd edition.

ETL has submitted a report to the ATSDR suggesting that a peer review panel would be an appropriate body to evaluate the Tetramitus Assay. ETL has agreed to this process, but requested additional time in order submit a later version which would include the results of the New York City Drinking Water and Croton Watershed studies.

ETL, with the assistance of Dr. Marina Larson, has filed a second patent application which deals with the use of other flagellate species for measuring size-specific particle toxicity. A preliminary application also was filed for the use of flagellate swimming patterns as an indicator of potential toxicity.
