Havelock Water Hardness & Quality Report (2026)

Havelock, North Carolina, in Craven County — the home of Marine Corps Air Station Cherry Point (MCAS Cherry Point), the largest Marine Corps air station in the world, a city dominated by the Marine Corps installation and its civilian workforce — receives its municipal water from the City of Havelock Water Department, which draws from Slocum Creek impoundment or from the Neuse River in the Craven County coastal plain.

The moderately hard 142 mg/L hardness and TDS of 330.8 mg/L reflect the North Carolina Coastal Plain's Cretaceous calcareous geology in the Neuse-Trent River valley. The Neuse River and Slocum Creek watershed drains the North Carolina Coastal Plain — underlain by the Cretaceous Black Creek Formation (calcareous marl, limestone, and glauconitic sand), the Peedee Formation (calcareous sand), and the Pleistocene terrace sand and shell-rich coastal deposits. The Aurora Phosphate Formation (Cretaceous marine phosphatic limestone) in Beaufort County and the broader Craven County Coastal Plain calcareous marl contribute moderate calcium and bicarbonate to the supply.

At 142 mg/L, Havelock's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 7.3 ppt warrants a certified drinking water filter — MCAS Cherry Point (Marine Corps Air Station — one of the largest AFFF users on the East Coast) and Marine Corps Auxiliary Landing Field Bogue are the primary documented PFAS sources for the Havelock-Craven County groundwater supply.
