Meador’s first study found that the survival rate of juvenile chinook that smolted in contaminated estuaries of rivers flowing into Puget Sound was cut in half compared with juveniles coming from a relatively uncontaminated natal estuary. Let me repeat that:Survival rate is cut in half.
In his second study, Meador analyzed the discharge from secondary sewage treatment plants, located upstream from chinook estuaries, for the occurrence of 150 “chemicals of emerging concern,” or CECs. These are chemicals associated with pharmaceutical and personal care products, as well as industrial compounds. Many are known endocrine disruptors, which can affect hormonal balance and result in developmental and reproductive abnormalities.

On February 23, the Seattle Times reported that researchers had found 92 chemicals of concern, some associated with drugs—from caffeine to cocaine—in the tissue of juvenile Chinook salmon netted in Puget Sound estuaries into which sewage treatment plants discharge effluent. The researchers also found the chemicals in the effluent from these plants. The Times story noted that scientist James Meador’s earlier research had shown that juvenile Chinook salmon swimming through contaminated estuaries in Puget Sound die at nearly twice the rate of fish elsewhere. Other scientific research has linked nutritional stresses experienced by endangered southern resident orca to the decline in abundance of chinook salmon
