Explaining environmental sampling (Part II)
Still have questions about environmental sampling? Good news. Inside CTEH is back to explain more about this process. We’ll also share how CTEH scientists use sampling to help keep communities safe from potentially contaminated air, sediment, soil and water sources.
Are the environmental sampling results reliable?
CTEH’s sampling protocols are based on U.S. Environmental Protection Agency guidance and regulations, which were designed to minimize the potential for cross contamination. The protocols also help ensure “duplicate samples,” or samples that are representative and repeatable. In addition, our analytical laboratories perform multiple calibrations and analyses to detect any potential cross contamination or interferences.
Why are third parties like CTEH needed to conduct sampling?
To put it simply, qualified third parties help eliminate the potential for bias in sampling.
How does environmental sampling help protect our health?
Before you can prescribe a remedy to clean up a hazardous chemical, you need to determine the extent of the leak or spill. Once you know the type, concentration and extent of the issue, you can design a solution to prevent adverse impacts to human health and the environment.
