Topic:

Geogenic Concentrations of Metals in the San Diego Embayment 

Results from the Bay Point Formation


Abstract:

Studies regarding the geogenic concentrations of metals in the native formations of San Diego County are underrepresented in the literature.  The concentrations of metals in soils is a fundamental criteria regarding remediation and determining disposal options for soils from contaminated or potentially contaminated properties in San Diego County.  Without an established naturally occurring range of concentrations, it is difficult to differentiate geogenic from anthropogenic signatures.

We present the results of over 200 in-situ geogenic soil samples from the Bay Point Formation of San Diego, California.  All of the soil samples were analyzed for metals following EPA 6000 / 7000 Series Methods by a California Certified Analytical Laboratory.  The 95% Upper Confidence Limit for 17 metals was calculated using the statistical software package ProUCL.

The results demonstrate that Arsenic concentrations detected during this study exceed commonly utilized health risk soil screening levels and other risked-based corrective action guidelines recognized by some regulatory agencies in California.  Additional research is needed to assess the bio-availability of the Arsenic, the potential impact to human health and the environment, and the impact these results may have on current regulatory screening levels and/or guidelines for assessing soils on occupied properties and development sites in San Diego County.

Further research is currently underway to identify the range of concentrations of metals in additional formations throughout the San Diego Embayment (e.g. San Diego Formation, Torrey Sandstone, Mission Valley Formation, Scripps Formation).  All data is currently being transferred into a centralized GIS database that is intended to be made available online for public use.
