Surfside Beach — known locally as "the family beach" — draws its municipal water from the same Grand Strand Water & Sewer Authority (GSWSA) system serving most of Horry County. That means the same hardness and disinfection byproduct profile applies here as in Myrtle Beach proper, but Surfside's dense mix of year-round residents and rental properties makes water quality a daily concern.
Hardness Is the Most Common Complaint
Surfside Beach city water is reported by the City of Myrtle Beach at about 54 mg/L on GSWSA water, which is classified as soft; private wells vary. Hard water is associated with scale on faucets and showerheads, residue on glassware, soap that doesn't lather well, and dry skin after showering. A free test gives you your home's actual reading.
Disinfection Byproducts
Chlorine treatment of river-sourced water can produce total trihalomethanes (TTHMs) and haloacetic acids (HAA5) — both federally regulated contaminants that form when disinfectants react with organic content in the source water. GSWSA publishes its measured levels annually in its Consumer Confidence Report.
Rental Property Considerations
Surfside Beach has a high concentration of vacation rentals. Hard water spots on glassware and chlorine odor are among the most common guest complaints property managers hear — a whole-house filtration system protects both your plumbing investment and guest satisfaction.
What Surfside Beach Homeowners Should Do
A free in-home test measures your hardness and disinfection byproduct levels directly at your tap, so you know exactly what a softener or carbon filter needs to handle.
