Monitoring for pesticides in other sample matrices, such as wastewater, soil, foliage, fish and oil is also important. By obtaining a variety of sample media one can determine the geographical deposition of various pesticides and how they are transported from one region to another, which in turn affects our drinking water supply. Investigating pesticide behavior and concentration levels in the environment provides us with valuable information necessary for implementing cleanup strategies and minimizing the hazards of these pesticides. The term pesticide includes several different classes of organic compounds. While not pesticides, these compounds are very similar chemically and are easily determined using the same instruments.
Every sample is run using two independent analyses to confirm the compound's identity.
All data is collected and stored on computers so that our chemists can carefully review the results using advanced graphical and integrating software. The analytical procedures that the chemist must adhere to are determined by EPA methods containing rigorous quality control requirements written specifically for identifying and measuring different classes of pesticides. Furthermore, each chemist participates in quarterly performance evaluations to retain lab certification . This ensures that our lab remains compliant with existing regulations and continues to produce the most accurate and legally defensible results for our clients. We are also contracted by the DNR, EPA and other agencies to provide results for research on the flow of pesticides into and through groundwater.
