Raritan Headwaters 35th Annual Stream Cleanup

Release Date: March 04, 2025

 

Raritan Headwaters is hosting its 35th Annual Stream Cleanup on April 12th, 2025, from 9 am to 12 pm. It only takes three hours to make an impact! At nearly 70 sites, more than 1,400 volunteers will collect over 15 tons of trash and debris along streams and connected landscapes - as litter on the land ends up in a waterway. Litter harms wildlife, water quality, and human health.

Join families, individuals, students, scout troops, churches, businesses, civic groups, and environmental commissions who want to clean up their community. Learn more at raritanheadwaters.org/streamcleanup. We look forward to seeing you on April 12th!
