In this paper, a GIS supported environmental risk assessment
using stochastic and fuzzy set theory has been proposed for
the petroleum-contaminated site. Employing the general
accepted regulation by USEPA, federal or local government,
and utilizing the expert opinions on the risk standard through
question survey. Environmental risk calculation in occurrence
possibility term for different age group and linguistic term risk
assessment have performed and the reasonable risk results
Integration of GIS technology with environmental risk
assessment has shown the capacity to maximize the utilization
value of available information. Through the creation of spatial
database and facility relational database, the advanced data
exchange and query function, and appropriate data which is
necessary for contaminant concern, risk-based decision
presentation has been determined, and relevant site physical
and chemical characteristic information can be presented
With the further enhancement of spatial and monitoring data
quantity and quality, a more comprehensive multi-pathway and
multi-scenario case study will be explored in the future
research improvement.
