Surface Water

NLS has been involved in low-level nutrient testing since the 1970's.  We performed numerous comprehensive lake management studies back then.  While we no longer have the time to do whole-project lake studies, we still provide unmatched analytical support for lake and surface water projects.

From low-level nutrient and metals analysis of lake and river samples to ultra-low level mercury or PCBs in a receiving stream, NLS is the go-to lab for dependable surface water monitoring.  We are also fully equipped to meet the WQX data submittal requirements for EPA funded studies.

Whether it is a simple spring or fall turnover lake sample or a full blown watershed study, our analytical support lends credibility to any final report.  Let us put our 38 years of experience and expertise to work for you.

Below are some of the categories of testing we offer:

  • Biological Contaminants
  • Inorganic Contaminants
  • Volatile Organic Compounds
  • Semi-Volatile Organic Compounds
  • Legacy Pollutants such as PCB, PCP and Mercury
  • Emerging Contaminants
