Morrisville Water Hardness & Quality Report (2026)

Morrisville is served by the City of Durham's water utility, which supplies 321,414 people across the service area. The primary water source is surface water from Lake Crabtree, located near Morrisville in Wake County. The utility operates treatment facilities to process water from this reservoir before distribution to customers in Morrisville and surrounding communities. For detailed water quality data, including pH, lead/copper testing results, and specific contaminant levels, customers can contact the City of Durham Water Department at 919-560-4381 (ext: 35258) or review the annual Consumer Confidence Report.

The Upper Crabtree Creek Watershed encompasses most of Morrisville and extends into Cary, situated within the Neuse River Basin. The watershed lies in the North Carolina Piedmont physiographic province, characterized by metamorphic bedrock and granitic formations. These geological features influence the mineral composition of the surface water supply, contributing to the water's chemical character as it flows through the landscape and imparting moderate mineralization typical of the Piedmont province.

Water from this supply meets all EPA Maximum Contaminant Level Goals (MCLGs), with all tested contaminants remaining within safe levels according to health-based guidelines. Standard water softening or conditioning may be considered based on individual household needs and appliance longevity concerns. Residents should consult the utility's most recent Consumer Confidence Report for specific hardness measurements and treatment recommendations, as the Durham water utility maintains compliance with federal drinking water standards.
