Natchez sits on the Mississippi River in Adams County, one of the most historically significant port locations on the lower river. The Port of Natchez handles barge traffic on the Mississippi River Navigation System connecting Adams County to the Gulf of Mexico and the entire inland waterway network, generating USCG-regulated employer exposure for marine vessel personnel and barge operations. Oil and gas production and services activity in the southwestern Mississippi and northeastern Louisiana region stages from Natchez, with pipeline and oilfield service employers on the US-61 corridor connecting to Baton Rouge and New Orleans. Manufacturing including International Paper operations adds industrial employer demand. US-61 (the Great River Road) and US-84 route freight between Natchez and the I-20 Jackson corridor to the north and Baton Rouge to the south. Natchez Regional Medical Center anchors healthcare employer demand. OnSite Employer Testing dispatches mobile collectors to Natchez port facilities, oilfield staging areas, fleet yards, and employer sites throughout Adams County when routing and collector availability allow.
