New Castle County Executive Matt Meyer announced the winners of this year’s Great Schools Clean Streams environmental education campaign, which enlisted area residents to raise awareness of the environmental harm from pouring kitchen grease and oils down the drain and into the county’s wastewater treatment system.

Residents participated in the Great Schools Clean Streams campaign by signing an online pledge at greatschoolscleanstreams.org to properly dispose of used cooking grease and throw it in the trash. Each participant assigned their pledge to the public, charter or private school of their choice in New Castle County, and the schools that collected the most pledges won cash awards they can use to purchase classroom materials and to support school projects.
