not like it would make a difference to anyone not liking the green, but it is natural, not nasty. reservoirs are clear cause of treatment, elsinore is a natural occurring lake with run-off from Cleveland national forest and the san jacinto river. but, i get it, green is green

lake elsinore has a website that explains a lot of it and also shows monthly tests of bacteria levels and so forth... as far as your oil leak? :-)
