For each month such reclaimed water is retained underground, the Division may credit the reclaimed water with 1-log enteric virus reduction. The Division may credit the reclaimed water with up to 10-log Giardia lamblia cyst reduction and up to 10-log Cryptosporidium oocyst reduction for treatment within the vadose zone.

2. An injection well must pass through a minimum of three separate treatment processes for pathogen removal. A treatment process may be credited with a maximum of 6-log reduction and a minimum of 1-log reduction. For Giardia lamblia cyst reduction and Cryptosporidium oocyst reduction, the point of compliance is at the point of injection. For each month such reclaimed water is retained underground, the Division may credit the reclaimed water with 1-log enteric virus reduction. The point of compliance is the point of extraction.
