AB: A stochastic surface interpolation technique, Kriging, is used to assess regional pathogen pollution levels. Assessment is carried out using several models fitted to semivariograms established from the available data. Data collected from the sampling efforts conducted as a part of PRIDE (Personal Responsibility in Desirable Environment) project in Southeastern Kentucky are used for this study. The main pollution causing sources in the study area are straight pipes and failing septic systems. Validation of interpolated data is achieved by using sampled data that are not included in the Kriging interpolation process. Causal validity of the interpolated results is also assessed using the pollution causing sources using a geographical information system framework. Preliminary results suggest that Kriging can be used for identifying heavily impaired watersheds due to pollution after sufficient confidence is established in the interpolation results.
