Your trusted analytical laboratory for more than 50 years.
A Proud Family Business
Where you are is not as important as who you are. In 1974 Ron and Winnie Krueger moved their family to the shores of Ground Hemlock Lake in Forest County to begin a lake management consulting business in support of Wisconsin’s Inland Lake Renewal Program.
Northern Lake Service Inc
NLS lab was born and raised in a tiny office and lab room at the back of the family garage. As lake management became less of an emphasis, NLS started providing lab services to wastewater clients and quickly ran out of space. In 1980, NLS moved into a historic building in Crandon, WI.
Continued Business Growth
In 2010 a second location was established in Waukesha, WI to better service the metro area. More than three decades, three major additions, and three generations later, our modern facility is home to a company that sets the standard for environmental lab services in the Midwest.
