The placement of wastewater residuals into the deep subsurface offers an alternative form of biosolids and brine management to the currently used surface disposal practices. This project resulted in the creation of a user-friendly map of the U.S. and southern Canada that shows areas with geologic strata appropriate for large-scale biosolids and brine injection. The report includes a guidance document that summarizes state-by-state regulatory requirements for permitting of brine and biosolids injection, and a case study of the City of Los Angeles TIRE (Terminal Island Renewable Energy) facility’s pathway to gain public support and approval of their project. An interactive map was created using Google Earth software (required for use) and the results accompany this report in both a Keyhole Markup Language (KML) file and a compressed KMZ zipped file. The map contains three layers, one that displays all major sedimentary basins, one that illustrates the locations for the top 80 WWTPs with the highest municipal daily flow rates, and one which describes state perspectives on biosolids and brine injection.
