ABSTRACT

Serpentine, a magnesium silicate mineral formed when peridotite is altered by extremely hot water during tectonic plate subduction and partial crustal melting from heat from the upper mantle, is composed of the plated minerals lizardite and antigorite crisscrossed by veins of chrysotile. In California, serpentinite is typically found within the Coast Range, Klamath Mountains and Sierra Nevada foothills. When analyzed for metals presence, serpentinite rocks typically contain elevated chromium (Cr), nickel (Ni). Chrysotile asbestos is often found in veins within serpentinite. Asbestos has also been identified at multiple locations in the bedrock of the northern New Jersey area, with most occurrences confined to the Precambrian marbles of the New Jersey Highlands and the basaltic rocks of Mesozoic age of the Newark Basin.

When project sites are evaluated for the presence of potentially hazardous substances or waste soil is analyzed for landfill disposal pre-approval, metals are part of the list of required analytes, but evaluation for the presence of asbestos is often not included. Following years of anecdotal observation, this research intended to evaluate whether the presence of elevated chromium and nickel concentrations could be a reliable indicator for the presence of chrysotile asbestos. If such a correlation could be made, at what concentrations would the presence of Cr and Ni be a predictor for chrysotile?

This study used data from soil samples collected within California’s Coast Ranges and reported within site investigation reports published for public use on the California Department of Toxic Substances Control Envirostor database and California’s State Water Resources Control Board Geotracker database. Data was evaluated using statistical tools to establish a threshold concentration for Cr and Ni, above which, serpentinite is likely to be the source and warrants additional analysis for the presence of chrysotile asbestos. To test this theory, elevated Cr and Ni concentrations from USGS were mapped to see if this method could be used as a reliable predictor for where to find serpentinite rock and was found to be successful in identifying a specific location in Maryland.

BIOGRAPHY

Sarah Kalika has over 22 years of experience as a geologist in the environmental consulting industry and a Bachelor of Science in Geological Sciences from the University of California, Santa Barbara. She has performed primarily environmental geoscience investigations during her career including Phase I & II property transactions, asbestos and lead surveys for renovations and demolitions, abatement oversight, geologic mapping and sampling for the presence of naturally occurring asbestos, asbestos dust mitigation plan preparation, area air monitoring for asbestos, construction storm water pollution prevention plan preparations and inspections, and health and safety plan preparation. She has successfully managed the investigation, regulatory agency interaction, documentation, and cleanup of many complex, high profile, and confidential development projects, including schools, agricultural redevelopment, commercial and residential properties, highways, and rail corridors.

As a California Certified Asbestos Consultant and Professional Geologist, Ms. Kalika has a unique combination of expertise with applying regulations originally written for asbestos in building materials to construction projects that impact asbestos occurring naturally within rock and soil. Ms. Kalika is skilled in navigating the often-complicated assortment of regulations that apply to asbestos and asbestiform minerals and provides awareness training sessions for workers who will interact with asbestos-containing soil or rock on jobsites.

As a member of the Association of Environmental & Engineering Geologists, she has served as chair of several operational committees as well as the Naturally Occurring Asbestos Technical Working Group and co-chaired the AEG Annual Meeting in San Francisco. She is currently on the Executive Council as Association President.

Ms. Kalika is a frequent public speaker and gives presentations for consulting companies, school districts, commercial property managers, and members of the Association of Environmental & Engineering Geologists
