Protect People and Wildlife from the Invisible Threat of Toxic Chemicals!

Toxic contamination often hits our most vulnerable communities the hardest-and you can help change that. King County is seeking a passionate Aquatic Toxicologist to spearhead our fight against "forever chemicals" (PFAS) and other Contaminants of Emerging Concern (CECs). In this role, you will do more than write reports; you will drive the science that protects the aquatic food web-from the orcas in the Sound to the fish on our dinner tables. If you are driven to address health disparities through rigorous science and want to protect those with the least resources from toxic contaminants, we want to hear from you!

About the Role: Join our team as we protect our most vulnerable communities and aquatic life, such as fish and orca, from toxic chemicals in the environment. Your work will help King County identify PFAS contamination in our wastewater and landfill systems. In doing so, you’ll help us better protect people and waters of King County.

We need a CEC expert who is driven to apply their scientific training to understand contaminants in our wastewater, stormwater, and landfill systems when the contaminant science is new and quickly evolving. If you love to work collaboratively with other scientists and utility managers to protect people and the natural environment from the hazards of PFAS and other CECs, this job is for you!

You will help us accomplish our goals in the following ways:

• Investigate Groundwater: Guide investigation of PFAS in groundwater at landfills and work with utility staff to develop and implement a monitoring program.
  
  
• Analyze Risk: Collaborate with other team members to interpret wastewater and biosolids PFAS data and prioritize risks to people and the environment.
  
  
• Plan Investigations: Assist with planning investigations of PFAS and other toxic contaminants in the wastewater conveyance system.
  
  
• Design Studies: Write study plans (SAP or QAPP) and coordinate sampling and analysis with King County’s Environmental Laboratory.
  
  
• Innovate: Help develop a Contaminants of Emerging Concern (CEC) Prioritization Tool and track stormwater treatment options for PFAS.
  
  
• Interpret Data: Interpret PFAS data for wastewater influent, effluent, biosolids, and groundwater by putting it into context relative to regulatory standards, other available data, and potential risk to the environment.
  

About the Team: The Science and Technical Support Section is a unique workplace where scientists build the scientific frameworks informing evidence-based policies and management decisions. We are a Seattle-based team of more than 40 technical staff producing credible and innovative, applied science and technical guidance to benefit people and the environment.

We lead environmental investigations, manage monitoring programs, and support clients and partners with technical services. We regularly collaborate with many County sections, local jurisdictions, universities, and state agencies and strive to protect the most vulnerable community members first.

This position is in the Toxic Chemical Assessment unit in this section, which conducts fish monitoring and designs studies to answer questions for utility and natural resource managers about toxic chemicals in our systems and the environment.
