Unfortunately the discharge from from sewage treatment plants contain drugs that do not get removed in the treatment process and that could be a source of of some of the more recent problems. Not a bright future for our waters and aquatic life. I spent all my early childhood summers wading in a creek in upstate NY so I can appreciate what you did as a kid. If AIMH produces like I believe it will, I'm taking my whole family to an all inclusive resort in NW Costa Rica...Paradisus Playa Conchal.
