Septic shocker


A Newton-based scientist says that septic systems may not remove natural hormone-disrupting chemicals like estrogen, allowing them to get into groundwater, the Reuters news agency reports.

Dr. Chris Schwartz of the Silent Spring Institute said that, while the human health implications of the findings are in hot debate, recent tests conducted on Cape Cod raise concerns about the health of unborn children.

"The biggest concern is for prenatal exposures, because fetuses are exquisitely sensitive to any type of hormonal imbalances during their development," he said.

About 25 percent of US households use septic systems. The test findings are being reported in today's issue of the journal "Environmental Science and Technology."
