Smyrna's water is slightly hard at 28 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill.

Contaminants & Safety
Disinfection byproducts are the notable finding here. Smyrna's water has TTHMs at 6.68 ppb and HAA5 at 2.13 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture?

About Smyrna's Water Supply
Water Utility: City of Smyrna Water
Water Source: Local wells (Groundwater)
Population Served: 13,467
Hardness: 28 PPM (1.6 grains per gallon)
Smyrna draws its drinking water from groundwater sources — Local wells. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 13,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Smyrna Water's Consumer Confidence Report (CCR) or test your own tap.
