DEQ WQ Toxics Monitoring, Quality Assurance Project Plan


Lori Pillsbury, 503-693-5735

In 2015, DEQ began its second round of monitoring for toxics around the state. This year, the laboratory is collecting water and sediment samples from locations in the Klamath, North Coast, Rogue, and Umpqua basins. Data from these samplings will be available in mid-2016.

Program Overview

In 2008, the DEQ Laboratory launched a statewide water quality toxics monitoring program. Lab staff sampled water, fish and sediment on a rotating basin basis. Land use, population pressures, past contamination and discharges were all factors in choosing monitoring sites.

Overall, goals for DEQ's Water Quality Toxics Monitoring Program are to:

  • Work with DEQ internal groups, community groups and Oregon citizens to identify opportunities for reducing these pollutants.
  • Gather information to characterize the presence and concentration of chemicals of concern in Oregon’s waters.
  • Use this information to identify sources of these chemicals.
  • Present and make available information gathered for public benefit.

The DEQ laboratory analyzes seven major categories of toxics. Read more about the specific toxics categories DEQ investigates.

DEQ laboratory staff collected samples on a rotating basin schedule during spring, summer and fall. Collection of all types of samples did not occur at each site. Access, site appropriateness, species availability and hydrology all determine the types of samples collected. Also, the lab does not analyze all types of samples for all the chemical categories described above. Some pollutants, because of their chemical structure and behavior in the environment, are more likely to be found in fish and sediment.

The lab works with other DEQ programs such as the DEQ Toxics Reduction Strategy and the Pesticide Stewardship Partnerships as well as with other state and federal agencies to carry out this work.
