b) The final site assessment shall provide:
1) results of laboratory analyses or field screening measurements
of agrichemical concentrations in soil and groundwater, including quality
control samples;
2) facility site maps, at a scale no larger than 1 inch equals
200 feet, of sufficient detail and accuracy to show all of the following:
A) the locations of all soil samples, keyed to a table of
analytical results,
B) the locations of any monitoring or water supply wells sampled,
