5/20/2020 - Method 334.0 Quarterly Verification
Method 334.0 Quarterly Verification (equipment verification only)
In September 2009, the Environmental Protection Agency (EPA) published Method 334.0. In 2018, the Pennsylvania Department of Environmental Protection (PaDEP) required compliance of Method 334.0. Many systems have done intial demonstration of capability for individuals who conduct chlorine analysis and have completed initial calibration verifications. To maintain Method 334.0 compliance, systems must complete Routine Calibration Verifications. PRWA will have staff at this training seminar to perform Routine Calibration Verification for participating systems instruments. Operators can choose to attend only the seminar, attend the seminar and have equipment verified, or just have the equipment verified. In addition to the instrument in need of routine calibration verification, paperwork specific to method 334.0 will be needed including:
- Initial Calibration Verification
- And, if completed at any time, quarterly instrument verification
In addition to the instrument(s) to be verified, the PRWA staff will need clean sample glassware. Also, if the instrument cannot be verified using a DPD pillow packet, the specific chemical/reagent needed should be provided.
