South Gate, Maryland, an unincorporated community in Anne Arundel County — a major south Anne Arundel County suburban community (South Gate is a significant Anne Arundel County unincorporated community — a south Anne Arundel suburban area in the Fort Meade corridor along MD-170 and the Anne Arundel–Baltimore County border; South Gate is part of the larger Ferndale–Linthicum–South Gate suburban cluster adjacent to Baltimore Washington International (BWI) Airport — one of the most strategically located airport-adjacent residential communities in the Maryland–DC metro area), a diverse Anne Arundel County community with a primarily working-class, military/federal government contractor, and suburban family population, adjacent to Ferndale and Hanover in the south Anne Arundel corridor, home of BWI Airport adjacent communities, and a community served by the Marc Penn Line commuter rail — draws its municipal water supply via the Baltimore City DPW. Water hardness in South Gate measures 180 mg/L — classified as hard.

South Gate's hard supply reflects the south Anne Arundel County BCDPW distribution zone's limited softening. The BCDPW distributes Liberty Reservoir supply through the south Anne Arundel County South Gate zone with limited softening, producing the hard 180 mg/L.

At 180 mg/L, South Gate residents face regular hard water challenges. Monthly descaling and water softeners are recommended. Baltimore City DPW consistently delivers water meeting all Maryland MDE and EPA Safe Drinking Water Act requirements.
