Book 94 The two lab tests in question were only to supplement other pilot test activities. The plant staff, including Bill McCain and Brad O'Keefe, and myself, conducted several tests with the pilot unit and confirmed that the pilot unit could indeed oxidize the hydrogen sulfide and eliminate the odor. We used analytical equipment at the plant to measure hydrogen sulfide residuals and chlorine residuals. However, without • obtaining additional analytical evidence on THM's, turbidity, and alkalinity, we cannot recommend that the chemical oxidation method be used since these parameters may impact the water quality. We are proceeding with the completion of our pilot testing, in cooperation with both Envirometrics and Harbor Branch Labs, and should be able to report our findings in _ about three or four weeks. If you have any questions or comments, please contact my office. Very truly yours, CAMP DRESSER & McKEE INC. William B. Suratt, P.E. Associate Director Pinto reported that he telephoned the owner of Envirometrics and had his staff call the other lab in question and has determined that the tests were simply inconclusive; however, Ms. Treadway of Envirometrics did not want to take responsibility for killing the project and wanted the Board to understand that Envirometrics was not responsible for the failure of the program. The major problem with the project was timing and the capital costs for both projects are very close to the same. However, the operating costs of the pilot project would be substantially less. Director Pinto believed we are heading in the right direction and has instructed staff to explain the project to the laboratories when requesting tests in order to obtain more significant results. Chairman Macht stated that the intention of the Board was not to cast blame, and he hoped that the owner of Envirometrics understands that was not the intention of the Board. Grace Treadway, President of Envirometrics, Inc., stated that the article in the newspaper took her by surprise and her letter was in response to that article. She subsequently met with William Suratt of Camp Dresser & McKee and the County's Capital Projects Engineer Bill McCain and they explained to her that it was not their intent to cast blame on Envirometrics. They have apologized and she has accepted the apology. She emphasized that Envirometrics is available at any time to work on a problem with the County. FEBRUARY 28, 1995 78
