According to the heads of the Infectious Disease Departments at all three of our local large hospitals, a chlorine level of 3 ppm with 0 CYA will make a pool safe from Hep B,C, HIV. (You'll have to trust me on this one, the ones who have been around the forum for awhile know why I happen to have this information! ) When I told them about a suspected contamination in my pool a few years ago, and explained that with a CYA level of 60 I ran my FC up to 30 ppm and held it there for 2 weeks, they all laughed and assured me that my pool was probably the cleanest place there was in the parish, and that none of them would have any problem swimming in it. Granted, it was overkill--they each pointed out that therapy pools in the hospitals have any number of diseased people in them throughout a given week....and nothing special is done to decontaminate, except to maintain a 3 ppm chlorine level on an inside pool.

When cleaning CPR manikins, they require us to use a 10% bleach solution....1/4 C bleach to 1 gallon of water, with a soak time of 10 minutes. So....I agree with the others.....normal chlorination should take care of it!
