Are there toxic chemicals in the Hyperion’s plant discharge? If they are present, are the levels of pollutants a concern to human health or to the health of the animals living in the Bay?
Sewage moving through the plant’s processes is tested to ensure that systems are operating properly to effectively remove pollutants. The sewage is analyzed for a variety of chemicals, many of which can be toxic or carcinogenic at certain levels. During 2003 through 2004, the presence of toxic or carcinogenic chemicals was rarely detected. With few exceptions in thousands of tests, these chemicals were either not present at all or were at such low levels that they could not be detected by the most sensitive instrumentation. In cases where they were detected, most were in concentrations well below the requirements of Hyperion’s NPDES permit and the objectives of the California Ocean Plan. Therefore, when detected, the pollutants were at levels that are considered protective of human health and the animals inhabiting the Bay.
