DBPR Requirements

As of January 1, 2004: Surface water and ground water systems under the direct influence of surface water (GWUDI) serving less than 10,000 people, and all ground water systems must comply with the Stage 1 DBPR requirements. This requirement affects all Community Water Systems (CWS) and Non-transient Non-Community Water Systems (NTNCWS) that disinfect.

Regulated Contaminants / Disinfectants Coverage Required Monitoring Frequency
TTHM/HAA5 Surface and GWUDI serving ≥ 10,000 4/plant/quarter
Surface and GWUDI serving 500 - 9,999 1/plant/quarter
Surface and GWUDI serving < 500 1/plant/year in month of warmest water temperature*
Ground water serving ≥ 10,000 1/plant/quarter
Ground water serving < 10,000 1/plant/year in month of warmest water temperature*
Bromate† Ozone plants Monthly at entrance to distribution system
Chlorite Chlorine dioxide plants Daily at entrance to distribution system; monthly in distribution system
Chlorine/Chloramines All systems Same location and frequency as Total Coliform Rule sampling
Chlorine dioxide Chlorine dioxide plants Daily at entrance to distribution system
DBP precursors (TOC/Alkalinity/SUVA) Conventional filtration systems Monthly for total organic carbon and alkalinity or the SUVA alternative

* System must increase monitoring to 1 sample per plant per quarter if an MCL is exceeded.
† Reduced Bromate monitoring may be available based on results of optional Bromide monitoring - See Stage 1 DBPR.
