Chapter 22

This chapter provides an integrated discussion of potential municipal and domestic water supply management options in response to implementation of the Lower San Joaquin River (LSJR) alternatives. Southern Delta water quality (SDWQ) alternatives are not discussed in this chapter, because a substantial degradation of water quality affecting service providers diverting drinking water from the southern Delta would not occur. This chapter incorporates information from Chapter 9, Groundwater Resources, and Chapter 13, Service Providers, in order to illustrate how potential impacts from LSJR alternatives would affect water supply to urban and rural populations in the San Joaquin Valley under current regulatory conditions. Current regulatory conditions include the Sustainable Groundwater Management Act (SGMA) (Wat. Code, § 10720 et seq.), which took effect January 1, 2015, and requires the formation of local agencies to protect and manage groundwater resources. SGMA is discussed in more detail below. This chapter also references project overview information from Chapter 1, Introduction; water resources and management descriptions from Chapter 2, Water Resources; project alternative descriptions from Chapter 3, Alternatives Description; and, cost information from Chapter 16, Evaluation of Other Indirect and Additional Actions.
