New Water Testing Method Development

The Regional Water Authority laboratory is currently working on the development and incorporation of three UCMR4 methods. The methods that will shortly be available to our customers are the following:

• EPA Method 557 (Brominated Haloacetic Acids)
• EPA Method 541 (Alcohols)
• EPA Method 530 (Semivolatile)

Currently, the laboratory is analyzing for both haloacetic acids and semivolatiles. Both analyses are being performed using an EPA approved procedure. However, EPA has specified the above-listed methods for UCMR4 and we want to ensure that we meet all our customer needs for both current and future requirements.
