    ASR in Roseville: Navigating Water Quality Issues: (attached)

    An ASR demonstration project in Roseville, California, is improving understanding of the water quality implications of underground injection and recovery. Results show a five-foot rise in groundwater levels, significant reductions in TDS levels, and attenuation of disinfection byproducts.
