Drinking Water

NLS DW (drinking water) testing ranges from investigative analysis to SDWA compliance. We were one of the first laboratories to receive SDWA certification when Wisconsin implemented the program back in 1987. We continue to develop new methods and hold more DW method certifications than any other Wisconsin lab. At last count, 176 public water systems have used our services for 15 years or more. During the last cycle (2014), we performed testing for more than half of Wisconsin's 612 municipal DW suppliers.

NLS would like to make each DW project run as smoothly as possible. We can assist in sample transport, such as automatic, scheduled bottle shipments. We do electronic data submittal for SDWA compliance samples, and offer paperless reporting. We have certified drinking water operators on staff who, with our client service department, can answer questions concerning sample collection to data results.
