Ms. Kaiser has 10 years of experience as an environmental professional, including more than 7 years in consulting. She works as a risk assessor, assistant project manager, data analyst, researcher, and health and safety coordinator. In these roles, her responsibilities have included human health and ecological risk calculations, project management, statistical analysis, site assessment, research, compliance assurance, sampling method development, and biotic and abiotic fieldwork.
Ms. Kaiser has experience evaluating human health and ecological risks from chemicals in soil, groundwater, surface water, tissue, and air on sites where PCBs, dioxins, PAHs, and/or metals are the primary chemicals of interest. She has provided technical support for multiple projects in Oregon, Washington, and California at a wide range of sites, including retail gasoline stations, bulk petroleum terminals, former gun clubs, abandoned mine sites, electrical substations, lumber mills, and in-water sediment areas. With an interdisciplinary background and a versatile skill set, Ms. Kaiser specializes in projects that do not fit into well-defined categories.

Permitting/Compliance
Assisted the client and its legal team in evaluating the client’s potential liability due to ownership and/or operation of properties within the Portland Harbor Superfund site. Specific tasks included considering the composition and distribution of contamination with river sediments, evaluating the contamination generated at neighboring properties, and preparing supplementary information for the Portland Harbor allocation team.
Developed responses, on behalf of clients, to 84 questions formally requested by EPA through the CERCLA 104(e) process. This work entailed compiling client information on historical and current site operations, spill history, environmental permitting, and waste production and disposal.
