Stage 2 D/DBPR Compliance Seminar

(NASHVILLE, TN – January 25, 2013) – Since their discovery in the 1970s, disinfection byproducts (DBP) have been a major concern for regulators, drinking water utilities, and the public due to their carcinogenicity and other potential health effects.

While most large systems are generally well prepared for Stage 2 D/DBPR compliance, many small and medium systems have yet to fully address the various changes in treatment and management practices that may be necessary to meet the new requirements.

The Stage 2 D/DBPR maintains existing maximum contaminant levels (MCLs) of 80 ?g/L for total THMs and 60 ?g/L for the sum of five HAAs from the Stage 1 D/DBPR, but focuses on a locational running annual average instead of a system-wide annual average, resulting in effectively stricter limits for many utilities of all sizes.

Hazen and Sawyer is a leader in developing cost-effective DBP reduction strategies for systems of all sizes, and has most recently developed a set of tools to help small and medium sized systems evaluate combinations of DBP reduction strategies based upon their own system-specific data.
