In cases where no water treatment was employed scenario A

Subsequent to pit water disposal, an equal volume of local fresh water was purchased and trucked back to the field (15 miles) for use during the hydraulic fracturing process [41] and [42]. Due to the current lack of comprehensive data on deep well injection facilities, no other inputs (e.g., facility construction, maintenance of the diversity well or 'AZD8055' high pressure pump, chemical inputs used during injection) were assumed. Furthermore, only the transportation impacts associated with truck operation for water transport were considered. LCI components such as truck maintenance and road damage were not included due to minimal information in the literature.
