The report says that it used the construction drawings to determine the location of the fly ash on the site. The construction drawings do not show the actual location of the fly ash. This has led to some confusion about the reliability of the conclusions in the report.
The most important data regarding the fly ash is the amount (approximately 1.5 million tons) and the general distribution. Since we used a distribution pattern which covered the width of the golf club, the model should be accurate and scientifically reliable without knowing the exact locations. The anomaly found in data results from the southwest corner of the site may be explained by the hills on that corner which may contain fly ash.
