Fla. Admin. Code Ann. R. 62-550.515 - Volatile Organic Contaminants Monitoring Requirements

Monitoring for the volatile organic contaminants listed in paragraph 62-550.310(4)(a), F.A.C., shall be conducted to determine compliance with the maximum contaminant levels.

(1) Monitoring Frequency.

(a) Initial base point monitoring. Each community or non-transient non-community water system shall take four consecutive quarterly samples for each contaminant listed in paragraph 62-550.310(4)(a), F.A.C., during the first compliance period.

(b) If the public water system does not detect any of the contaminants listed in paragraph 62-550.310(4)(a), F.A.C., it shall sample annually beginning with the next compliance period.

(c) If the initial monitoring for contaminants listed in paragraph 62-550.310(4)(a), F.A.C., as required in subsection (1) of this section, was completed between January 1, 1988, and December 31, 1992, and the system did not detect any contaminant listed in paragraph 62-550.310(4)(a), F.A.C., then each ground water system and subpart H system may take one sample annually beginning January 1, 1993.

(d) After a minimum of three years of annual sampling, ground water systems with no previous detection of any contaminant listed in paragraph 62-550.310(4)(a), F.A.C., may take one sample during each compliance period.

(e) Subpart H systems and ground water systems may apply to the Department for a monitoring waiver as specified in Rule 62-560.545, F.A.C.

(2) Sampling location. During the first quarter of the initial base point monitoring, ground water systems shall take a minimum of one sample that is specifically representative of each well. It may be collected as a raw or treated sample. Subsequent samples shall be taken as required by subsection 62-550.500(5), F.A.C.

(3) Monitoring Frequency After a Contaminant Is Detected. If a contaminant listed in paragraph 62-550.310(4)(a), F.A.C., is detected at a level exceeding 0.0005 milligrams per liter in any sample:

(a) The system shall notify the Department within seven days of receiving the laboratory results and shall monitor quarterly for that contaminant at each sampling point that resulted in a detection.

(b) The Department shall decrease the quarterly monitoring requirement of this section to annually if the system has results from four consecutive quarters that are below the MCL, unless the system enters into another schedule as part of a formal compliance agreement with the Department. After three years of annual sampling with no detection of the contaminant, a ground water system may decrease the annual monitoring requirement to one sample each compliance period.

(c) Systems that monitor annually shall monitor during the quarter that previously yielded the highest analytical result for that particular contaminant.

(4) Compositing of samples is allowed as provided in subsection 62-550.550(4), F.A.C.
