The Hazardous Waste Management Program is seeking an enthusiastic and dedicated Health & Environmental Investigator I/II (HEI) for our Residential Services Program. A key responsibility of this position is to provide individual case management and in-home assessments to families of children with elevated blood lead levels. The HEI will work closely with families, particularly women and children from refugee and immigrant communities. This work requires an individual who is willing to understand the needs of these families and provide services in a manner that is consistent with the family’s values, beliefs, and practices.  It also requires awareness and sensitivity to the historical and present-day trauma that people in many of our communities carry. The successful candidate will be able to approach this work with humility and an openness to self-reflection and learning.  

This work also involves using a community-centered approach to help plan, implement, and evaluate projects designed to reduce exposure to hazardous materials in the home. The HEI will work in partnership with others to provide public education, outreach, and awareness on hazardous materials found in the home, advise residents on ways to reduce exposure, and evaluate community adoption of any recommended actions. Project teams are currently working in partnership with community-based organizations to encourage safer cleaning practices. However, the successful candidate should be prepared to work on a wide array of topics pertaining to hazardous materials in the home.

Through the work of over 150 dedicated employees, the Environmental Health Services Division identifies and sustains environmental conditions that promote health equity and healthy people and communities in Seattle and King County.  Our vision is healthy, safe, and vibrant communities that are free of health disparities based on race, gender, or economic status.  The Division’s core values include equity and social justice, integrity, community service, collaboration, a supportive work culture, and learning from each other and the communities we serve.
