Groundwater Collection

NLS has played a significant role in Wisconsin’s groundwater monitoring program since its inception. Beginning in 1975 we installed and sampled over 250 monitoring wells in conjunction with Wisconsin’s Inland Lake Renewal program. By the mid-1980s we were sampling landfills, spray irrigation, and lagoon sites. Our mobile lab allows for effecient sampling. Our inline field filtration procedure minimizes pre-filtration oxidation.  Our methods were soon incorporated into Wisconsin DNR’s formal Groundwater Sampling Procedures Guidelines.

NLS field crews presently monitor over 1300 wells and lysimeters at 80 sites in Wisconsin and Michigan.  We have monitored half of these sites since the year 2000.  Our clients recognize the value of  precise, dependable groundwater data, and we are pround to have earned their confidence in the value of our monitoring program.
