The drinking water in Mount Pleasant, SC generally meets all federal health standards, earning a solid B grade with a composite safety score of 82/100 across 3 ZIP codes. While the primary water utility, Mt Pleasant Water Works (1010002), maintains adequate compliance with EPA regulations, there have been minor or administrative violations on record. Overall, residents receive safe tap water that is actively monitored by South Carolina Department of Health and Environmental Control.

Over the past 5 years, Mount Pleasant has recorded 3 health-based violations. While occasional violations can occur due to seasonal changes or temporary infrastructure issues, Mt Pleasant Water Works (1010002) is legally required to resolve these quickly and notify the public via their annual Consumer Confidence Report. The city's water supply, primarily drawn from surface water, is treated to address these specific contaminants.

Fortunately, the modeled risk for widespread lead exposure in Mount Pleasant's municipal water is relatively low compared to national averages. However, because lead typically enters drinking water through the corrosion of older, individual home plumbing rather than the main supply lines, residents in homes built before 1986 should still exercise caution by running the tap before use.
