Aquifers to be sampled shall include, but not necessarily be limited to, the St.
Charles River alluvial aquifer and the Dakota aquifer. During and after drilling of
the supply well into the Dakota aquifer, logs of those wells shalt be examined to
determine if water was encountered in the Codell Sandstone. Provided water is

Groundwater samples shall be collected and analyzed from a minimum of 8
separate events over a time span of at least 5 quarters. D1vIG recommends sampling
