SUMMARY:Fall Salt Snapshot Day

Meet outside of Cedar’s House off of Forbidden Drive and Northwestern Ave and then travel to locations within the Park for water collection.  If you have a car or bicycle\, that will be helpful.  Please RSVP through Eventbrite.   Contact us at wec@phila.gov for more information.   This citizen science project is a project of the Stroud Water Research Center. \nWater samples will be tested in the afternoon at WEC.
