The U.S. Geological Survey tested waters for 95 different chemicals from commonly used household products. Of 139 streams studied in 30 states, 80 percent had trace chemicals from sprays, cologne, headache pills, cholesterol-lowering medicine, body lotions and coffee. Research shows that sex steroids from oral contraceptives can feminize male fish and change behaviors of either sex and antidepressants make shellfish spawn too early or too late. Research has tied a decline in human male sperm count to low levels of birth-control hormones in the environment. The Stalk Institute’s Schubert said birth-control pills in tiny concentrations in wastewater can be enough to make cancerous prostate and mammary tumors grow aggressively. These substances escape water treatment processes and are not tested for. At present, 16 percent of Florida’s wastewater, 93 million gallons a day, is put underground, potentially degrading ground water quality in ways we have yet to understand. Septic tanks are also incapable of removing any of the problematic chemicals and deliver them directly into groundwater.
