The Healey-Driscoll administration on Jan. 20 announced the award of $830,000 in grants to nine Cape Cod municipalities to support projects that reduce nitrogen pollution and help the towns meet septic system and water protection regulations.

The grants were awarded through the Natural Resource Nitrogen Sensitive Areas Grant Program, administered by the Massachusetts Department of Environmental Protection, which helps communities develop plans to address nitrogen pollution from wastewater and other sources.

Excess nitrogen fuels the growth of nuisance plants, weeds, and algae that use up much of the oxygen in the water, which harms water quality and forces out indigenous fish and plant species.

Grants between $7,182 and $150,000 were awarded to Barnstable, Bourne, Brewster, Dennis, Falmouth, Mashpee, Truro, Wellfleet and Yarmouth.
