(a) Aquifer identification. Using Texas Water Development Board aquifer names, the aquifer(s) underlying the proposed subdivision which is planned to be used as the source of water for the subdivision must be identified and generally described.(b) Geologic and groundwater information. To meet the requirements of this chapter, the following geologic and groundwater information must be considered in planning and designing the aquifer test:(1) the stratigraphy of the geologic formations underlying the subdivision;(2) the lithology of the geologic strata;(3) the geologic structure;(4) the characteristics of the aquifer(s) and their hydraulic relationships;(5) the recharge to the aquifer(s), and movement and discharge of groundwater from the aquifer(s); and(6) the ambient quality of water in the aquifer(s).
