(1) The need for monitoring shall be determined by the type of well, nature of the injected fluid, and water quality of the receiving and overlying aquifers.
    (a) Except as provided in paragraph (b) below, the Department shall require monitoring for the following:
    1. Group 1 wells operating on an open-loop system or with provisions for additives, Group 3, Group 4, Group 5, and Group 8 motor vehicle waste disposal wells;
    2. Group 2 and Group 7 wells except when the injection fluids meet the primary and secondary drinking water standards contained in Fl. Admin. Code Chapter 62-550, and the minimum criteria contained in Fl. Admin. Code R. 62-520.400; and the injection fluids have been processed through a permitted drinking water treatment facility;
    3. Group 6 and Group 9 wells, except swimming pool drainage wells, if injection is into an underground source of drinking water; and
    4. Any Class V well where either an exemption from water quality criteria under Rule 62-520.500 or 62-520.510, F.A.C., or an aquifer exemption under subsection 62-528.300(3), F.A.C., was required.
    (b) The Department shall not require monitoring for the following:
    1. Wells used to inject fluids that meet the primary and secondary drinking water standards contained in Fl. Admin. Code Chapter 62-550, and the minimum criteria contained in Fl. Admin. Code R. 62-520.400, and that have been processed through a permitted drinking water treatment facility;
    2. Air conditioning return-flow wells and swimming pool drainage wells receiving a general permit under Rule 62-528.705 or 62-528.710, F.A.C.; or
    3. Other Class V wells that the Department determines through the process described in subsection 62-528.100(2), F.A.C., will provide reasonable assurance of compliance with this rule, without monitoring.
    (2) The Department shall determine the frequency of monitoring based on the location of the well, the nature of the injected fluid and, where applicable, the requirements of Chapters 62-600 and 62-601, F.A.C. The monitoring parameters and frequency shall be addressed in the Class V permit or authorization to use a Class V well under subsection 62-528.635(4), F.A.C.
