Description
Neural network modeling was used to examine the relationships between multipleinterrelated water quality and quantity parameters at the intake to a water treatment facility located on the Delaware River. The relationships were used to train a neural network model to predict peak concentrations of Cryptosporidium oocysts at the intake of a New Jersey water treatment facility. Input parameters to the model were selected based on their correlation with oocyst concentrations and stepwise evaluation of neural network training. The final trained neural network model predicted two conditions of input Cryptosporidium concentrations,background and above background (assigned as 1 and 0, respectively), from eight other water quality parameters. Clostridium perfringens concentrations were the most significant input parameter in predicting the final model’s performance. Turbidity was the least significant parameter. Furthermore, a site-specific, linear relationship between the numbers of full oocysts and the total number of oocysts recovered by the Information Collection Rule method at the water treatment plant intake was noted (full oocysts = 0.595 x total oocysts, R2 = 0.9011). Includes 15 references, tables, figures.
