a The documentation should identify in which aquifer the well being evaluated is screened. All wells in this example are assumed to be screened in the same aquifer. If wells were completed in more than one aquifer, add a column to the table that identifies the aquifer.

b The numbers in the reference column would identify particular references in the HRS scoring package.
