Keeping Pace^® with Analytical Services

Sherri Lloyd, Product Marketing Manager at Pace^®, spoke with Mariah Peronto, Air Program Manager for Pace^®, to discuss the Air Center of Excellence which officially opened in May 2023.

Whenever The United States Environmental Protection Agency (EPA) comes out with a new PFAS regulatory proposal, we inevitably get a lot of questions. The National Primary Drinking Water Regulations (NPDWR) proposed for PFAS on March 14^th were no exception. While the EPA held a couple of informational webinars that were highly informative, the Pace® PFAS Team wanted to offer some clarity as well.

In November 2023, significant revisions to the United States Pharmacopeia (USP) General Chapter <797> will go into effect, bringing critical updates to the environmental monitoring standards governing the compounding of sterile preparations. In this post, we delve into the changes to USP 797 BUD standards and how they impact environmental testing requirements.

In this edition of Keeping Pace^® with Analytical Services, we focus on EPA Method TO-15A.

Here’s What You Need to Know About PFAS

Stack testing, also called performance testing or emissions performance testing, is a procedure for sampling various types of emission sources at a facility. It is a critical tool to determine compliance with U.S. Clean Air Act regulations, state regulations, and air permits. It also provides real-world data for emission inventories and air quality modeling.

An Interview with Chris Johnson, Product Manager - Air

Did you know that testing has shown certain tubing and other sampling media can potentially emit or adsorb VOCs which may impact the results of vapor intrusion (VI) testing? This becomes important when sub-ppbv reporting limits are required for soil gas sampling to risk-based screening levels. To meet the risk assessment goals of soil gas samples, Pace® is often required to report compounds of concern down to the part per billion ranges or lower.
