Ms. Kalmes is a certified industrial hygienist with over 20 years of health risk assessment experience. In this role, she is responsible for designing, conducting, and managing technical studies addressing environmental, and occupational impacts of chemical agents. Ms. Kalmes has developed and conducted sampling programs to evaluate potential chemical exposure in air, soil, and groundwater and has prepared over 100 exposure and risk assessment for various properties, including former landfills, industrial, residential, recreational and agricultural properties and schools, including Brownfields Sites. She has evaluated potential exposure to metals, pesticides, volatile organic chemicals and petroleum products in soil, groundwater and air and developed clean-up levels and other risk management recommendations. Ms. Kalmes has evaluated soil vapor intrusion issues through use of soil vapor modeling and air monitoring tools. She has communicated risk results to a variety of stakeholders, including neighborhood, worker and community groups. Ms. Kalmes has taught more than 15 courses on risk assessment at the University of California Extension Program and has developed and conducted more than 100 training programs. Currently, Ms. Kalmes specializes in conducting and directing studies to assess potential exposure to consumer products including evaluation of benzene, toluene, lead, cadmium, arsenic, phthalates, ethyl benzene and formaldehyde. She has developed sampling protocols to evaluate FDA and CPSC and Proposition 65 claims, specifically addressing dermal contact and incidental ingestion of metals associated with hand-to-mouth activities. Ms. Kalmes has also conducted numerous exposure assessment analyses of community and occupational exposure data for use in cohort and case-control epidemiologic studies. In this role she has designed and managed air sampling programs to evaluate various job classifications to be used in epidemiological studies. She has evaluated community and occupational exposure issues associated with asbestos, beryllium, sulfides, and chlorinated hydrocarbons.

Proposition 65/Product Evaluations—Conducted Proposition 65 evaluations assessing potential exposure to children and adults for various chemicals including benzene, toluene, lead, cadmium, arsenic, phthalates, ethyl benzene, and formaldehyde, and various products (PVC, jewelry, containers, toys, cookware and tableware, and appliances). Developed sampling protocols to evaluate FDA and CPSC compliance, as well as exposure to metals in consumer products, specifically addressing dermal contact and incidental ingestion associated with hand-to-mouth activities. Managed product-testing programs for three major companies involving lead content of products. Evaluated dermal and oral migration of phthalates in various consumer products. Industrial Hygiene—Provided reviews of health literature, air sampling methods, and worker exposure data for silica, beryllium, and asbestos and their associated products. Conducted air sampling for numerous compounds such as volatiles, oil mists, pesticides, and particulates. Audited and reviewed health and safety compliance programs for petrochemical, agricultural, laboratory, and chemical manufacturing facilities, including review of labeling, MSDSs, training manuals, safe chemical handling procedures, ventilation, and employee training, and chemical inventory procedures. Exposure Reconstruction/ Occupational Epidemiology—Conducted numerous exposure assessment analyses for use in cohort and case-control health studies including petrochemical, aircraft, chemical, and agricultural industries. Designed and managed air sampling program to obtain 8-hour, peak and short-term levels for various job classifications to be used in epidemiological studies. Performed exposure reconstruction studies to evaluate chemicals such as benzene, silica, formaldehyde, lead, and asbestos. Risk Assessment/Brownfields—Managed numerous assessments of contaminated property for future residential, commercial, and school developments, while working closely with regulatory agencies to obtain approval of health-based strategies. Key issues for these sites included soil gas vapor migration, particulate emissions, and groundwater transport and fate modeling. Developed health based cleanup levels for scenarios such as residential, commercial, construction, and trespassers. Has successfully worked on sites involving chemicals such as TCE, PCE, 1,1,1,-TCA, EDB, PAHs, arsenic, lead, barium, and mercury.
