IID annually conducts Title 22 (of the California Code of Regulations) source water sampling and analyses on behalf of local public water systems to facilitate their annual production of a Customer Confidence Report (CCR). The All American Canal and three main supply canals (East Highline, Central Main, and Westside Main) are sampled each year for certain constituents as required by law and in coordination with the Drinking Water Field Operations Branch of the California Department of Health Services.
