Very high ammonium levels - very unusual for the creek. I rang EPA to report this (ref # 331657). I spoke with Trevor Hausler (WW, MCMC) who said high ammonium levels usually indicate sewerage. Visually the creek was clear, and I couldn't smell anything in particular, however there is a sewerage line running under where we test and a methane outlet pipe, so the place always smells like sewerage.
