TTHMs and Stage 1 Disinfectant/Disinfection By-Product (D/DBP) Parameters
For the following parameters monitored under Stage 1 D/DBP regulations, the level detected is the annual average of the quarterly averages:  Chlorine, Haloacetic Acids, and TTHM (MCL 80 ppb). Range of Results is the range of results (lowest to highest) at the individual sampling sites.
Contaminant and Unit of Measurement	Dates of sampling (mo./yr.)	MCL Violation Y/N	Level Detected	Range of Results	MCLG or MRDLG	MCL or MRDL	Likely Source of Contamination
Chlorine (ppm)	1/06-12/06	N	0.8	0.6 - 1.2	MRDLG = 4	MRDL = 4	Water additive used to control microbes
Haloacetic Acids (five) (HAA5) (ppb)	3/06-12/06	Y*	123.9	10.5 - 209.8	NA	MCL = 60	By-product of drinking water disinfection
TTHM [Total trihalomethanes] (ppb)	3/06-12/06	Y**	124.8	24.1 - 226.58	NA	MCL = 80	By-product of drinking water disinfection
