Low Level Mercury

The Clean Water Act has prompted many states, including those in the Great Lakes Basin to take swift action in regards to the levels of Mercury allowed to be dischaged into the watershed.  It was for this reason that NLS invested a great deal of resources to provide ultra-low mercury detection limits on effluent wastewater and ambient samples collected by customers. 

NLS was the first lab to be approved by the Wisconsin Department of Natural Resources for the analysis of low-level mercury samples.  Our highly specialized atomic fluorescence spectrometer is used in conjunction with modified versions of EPA Methods 245.7 and 1631 resulting in LODs in the low ppt range.

Collection kits are provided from the lab and include field duplicates and trip blanks.  For more information on this program please contact our lab today.
