I work as an environmental consultant, testing air toxics. I use this lab for Method 30B mercury trap procurement and analysis by CVAA. This lab has great customer service, good standard turnaround times, and excellent priority turnaround times. Quality work, which makes my work life easier. I was just happening to update my companys list of preferred labs, and noticed the 1 star review. I dont usually leave reviews, so I thought I would procrastinate a bit more... And, leave a more accurate review.
