Columbia Water FAQ

Is Columbia SC tap water safe to drink in 2026?

Columbia tap water meets EPA federal drinking water standards and scores 82/100 (Good) on PurityMap for 2026. For most healthy adults the water is considered safe but point-of-use filtration adds an important layer of protection.

Does Columbia SC use chlorine or chloramine for disinfection?

Columbia uses chloramine as the primary disinfectant with a residual level of 1.5 ppm. Chloramine is harder to remove than free chlorine and requires a catalytic carbon or reverse osmosis filter. Standard Brita-style pitchers will NOT remove chloramine.

Columbia water hardness is 2.8 grains per gallon (soft) with a TDS of 95 ppm (good). This level is unlikely to cause significant scale buildup in household plumbing.

Has PFAS been found in Columbia SC drinking water?

Based on available EPA UCMR5 monitoring data as of 2026 PFAS have not been detected above EPA advisory levels in Columbia drinking water.

What is the best water filter for Columbia?
