Sounding The Alarm On Silent Noncompliance
7/5/2019
Water and wastewater utility operators work diligently to operate within strict guidelines, ensuring their facilities are producing the best drinking water and highest quality effluent possible. Despite all their efforts, however, it can be easy to fall outside of regulatory compliance without even being aware. The key to avoiding problems like these is to understand how silent noncompliance can happen and knowing when to raise a red flag.

What Can 2nd Generation ATP Do For An Operator Or Field Technician?
11/1/2018
It’s important to start with the fact that this is not a regulatory test. This technology won’t replace any required compliance tests and the results are not reportable, which is actually a great benefit to our users. While regulatory testing is important, compliant does not necessarily mean clean.

Coping With Mixed-Source Water Quality And Corrosion Challenges
10/12/2018
When it becomes necessary to expand or blend water supply sources, variety is not necessarily the spice of life. Whether new water sources are surface water or groundwater, fresh, brackish, seawater, or water recovered from aquifer storage, they can ultimately impact water treatment plant (WTP) operations and finished water quality — including compliance with the U.S. EPA Lead and Copper Rule.

EPA’s ENTACT Study Breaks New Ground With Non-Targeted Research
8/1/2018
EPA scientists are leading a multi-phase project to evaluate the ability of non-targeted analysis laboratory methods to consistently and correctly identify unknown chemicals in samples. EPA’s Non-Targeted Analysis Collaborative Trial (ENTACT) was formed in late 2015 and includes nearly 30 academic, government, and industry groups. Non-targeted analysis involves analyzing water, soil and other types of samples to identify unknown chemicals that may be present, without having a preconceived idea of what chemicals may be in the samples.
