The OC Health Care Agency (HCA) is a regional provider, charged with protecting and promoting individual, family and community health through coordination of public and private sector resources. The HCA's service environment is complex with 180 different funding sources and over 200 State and Federal mandates. The mandates under which the HCA operates require the County of Orange to provide for, or to regulate, certain health services. Many of of HCA's services are preventaive in nature and therefore are not readily apparent to the public. Some examples include food protection, hazardous waste regulation, water quality monitoring, mental health services, substance use disorder services, communicable disease control, immunizations and public health clinics.
