|About this project|
This project was a collaboration of the UNC Research Translation Core (UNC RTC) and the NC Division of Public Health (NC DPH). The purpose of this project was to develop the capacity of NC DPH to identify North Carolina populations at greatest potential risk from well water contamination and enhance the public's understanding of environmental exposures, distribution of contamination, and the impact of groundwater on human health.
Data used in this project
The data used in this project were all private well tests received by the NC State Laboratory of Public Health from 1998-2010. Investigators used these data to map the concentration of 31 contaminants, many of which are also Superfund priority chemicals. The maps represent the average concentration of contaminants detected in each county as well as National Priority List sites and facilities that reported to the Environmental Protection Agency (EPA) Toxics Release Inventory. EPA data were included to increase public awareness of hazardous wastes sites and other sources of toxic releases throughout the state.
All maps created from this project represent the average concentration of contaminants detected in private well water samples in North Carolina counties. Two maps are available for each contaminant--one map represents the average of all data from 1998-2010, the second map reports the average of all well samples collected in the year 2010.
In addition, advanced mapping and geocoding techniques were used to characterize two contaminants--arsenic and perchloroethylene (PCE). A Bayesian Maximum Entropy (BME) framework was utilized to predict the concentrations of these two contaminants in unmonitored locations and to characterize spatiotemporal changes in the distribution of these contaminants.
