No just free chlorine is fine since that is the residual used at McMullen and you are using a continuous analyzer. I would recommend measuring total when the continuous instrument is verified weekly. I also told Seth he could rely on DMWW's weekly instrument verification or vice versa, depending on what you want to work out, if at all.

Do we need to have both free and total chlorine at that station? There is currently only a free chlorine analyzer at the station. JANET GASTINEAU
