Continue stream flow gaging at the sites shown on Table 3 of Attachment C; 4. Conduct additional monitoring and data analysis to ascertain the occurrence and distribution of additional parameters of concern to local water suppliers, to include bromide, chromium (hexavalent, trivalent, and total), and 1,4-dioxane in the Monitoring Project study area; 5. Summarize Monitoring Project water-quality data in a series of 3 biennial reports covering the following periods: 2016-2017; 2018-2019; and 2020-2021), anticipated to be produced by the end of September in the year following respective data collection; 6.
