Zoning Board of Appeals Chair Ken Ferreira was appointed to the Board of Health at the Tuesday September 17, Board of Selectmen's meeting.

Ferreira said he was approached by a Board of Health member because they were looking for someone with engineering experience, and Ferreira is a professional engineer. He also serves on the Zoning Board of Appeals.

In February of 2013 The Board of Health passed a regulation requiring that all new construction projects, or homes with failed septic systems within 500 feet of a body of water install "denitrification" septic systems.

The old regulation required the systems for new projects within 150 feet of a body of water.

Denitrification systems remove some nitrogen from the wastewater. Too much nitrogen spurs algae blooms which can kill fish and other marine life.
