Few labs in the country are as qualified to help you comply with the UCMR. MWH Labs provided the EPA with expert review UCMR1, which required all utilities serving populations over 10,000 plus some 800 smaller utilities to monitor drinking water for specific contaminants on List 1 and 2 using specific methods and quality control requirements. We also co-authored the official EPA method (314.0) for perchlorate analysis, and served on the AWWARF/EPA Chemical Contaminant List (CCL) research team that evaluated test methods for List 2 contaminants.
During UCMR1, MWH served as a primary contractor for monitoring UCMR compounds for EPA. In this contract we analyzed over 2000 samples using methods 524.2, 525.2, 515.4, 314, 526, 528, and 532, with QC requirements that exceeded Federal regulations. Our experience with some of these methods dates back nearly ten years, when we performed the National Pesticide Survey for the EPA.
UCMR2, scheduled to take effect in July 2007, will require even more stringent quality control and will require EPA approval of all participating labs, based on data packages and proficiency testing. For UCMR2, MWH was the first lab in the country to submit an application package to EPA for laboratory approval. The methods that are currently expected to be required in UCMR2 include 529 (explosives), 527 (PDBEs), 331 (perchlorate), 521 (nitrosamines), 525 (pesticides), and 535 (pesticide degradation products. Proficiency testing samples for UCMR2 are expected later this spring. MWH expects to be able to support you with your UCMR2 compliance.
