Just got this update from Lynne with the Parks Department ...
Good news. The fire marshal checked the substance & it had a neutral pH. He does not think it is a petroleum chemical. The water looks very clean near the discoloration. I think it might be iron from the ground water. Just to be sure, I have sent one of our naturalists to check it out. I’ll
let you know if he finds anything.
More good news. The managers from the car wash & Jiffy Lube agreed to clean up the trash behind their businesses along the stream banks where our volunteers could not reach. There is a significant amount of trash back there. We’ll try to keep better track of that area.
