Antietam Creek Watershed Alliance (ACWA) is dedicated to promoting, protecting, and restoring the Antietam Creek as a sustainable resource for the community.

ACWA is a grass-roots, volunteer based 501(c)3  focused on the care and protection of the Antietam Creek Watershed.  We provide the opportunities for citizens to become engaged with the Creek or in their backyards as well as provide education to empower individuals to make a difference in the watershed.
