Langan Addresses Environmental Liability at Legacy and Renewable Energy Sites
Utilities play a fundamental part of everyday life, supplying gas and electricity to residential, commercial, and industrial properties around the world. Unfortunately, the production, storage, and delivery of gas and electricity has resulted in a legacy of soil and groundwater contamination. While utility companies are moving toward clean and renewable energy sources, they remain obligated to investigate and remediate legacy contamination. Langan has supported the utility industry for over 25 years, providing various environmental services at both legacy and renewable energy sites

ASSESSING DATA QUALITY USING DATA VALIDATION
As engineers, geologists, and environmental scientists, it is in our nature to question things: Why did a particular event occur? What are the current site conditions? How are things changing?
So why shouldn’t this curiosity also apply to the analytical data used to make project decisions?
We should question whether laboratory results are “good enough” for the project’s data quality requirements. And what it means if a surrogate is recovered high, or if a holding time is exceeded, or if the field blank is contaminated.
