Photo: Not sure exactly what is being dumped but the masks make it look like a no, no... as seen at Dauphin and Van Pelt #Philly

Workers dump liquids into storm drains along Dauphin St. at N. Van Pelt on Wednesday morning May 16, 2012. Unsure what the contents are but the masks do not help. Made these photographs as I was trying to track down a N. Philadelphia fire on Wendesday morning. Alejandro A. Alvarez / Philadelphia Daily News / © 2012 Philadelphia Media Network
