Drainage Canal Survey, Hickam Air Force Base, Hawaii
1993
Curtis, Darrin L.
Personnel from Armstrong Laboratory Water Quality Function conducted a drainage canal survey at Hickam AFB HI from 16 to 27 Mar 92. The scope of the survey was to indicate if current water quality in the canals is within Hawaii Water Quality Standards. Significant findings were: seawater samples should only be analyzed by trained personnel familiar with the procedures for marine samples; biota should be resampled and analyzed for metals in ppm wet weight; the uppermost site in the Transportation Canal should be resampled and analyzed for metals to verify elevated levels; canal water turbidity levels are above state standards and should be addressed with the state (the levels are likely due to nature, such as tidal flow and fish waste with some slit influence); cadmium and silver samples should be resampled and analyzed using the seawater/ brine procedure; and all marine samples submitted to any laboratory should be clearly marked on the sampling form and container to note that it should be handled differently than normal freshwater samples. It was found that little information is available about tropical estuarine systems and information may have to be found locally, either from the state or local contractors familiar with tropical estuarine systems.
