What Makes Tucker's Water Unique?
Local geology and source profile
Tucker, Georgia, in DeKalb County — a major northeast Atlanta suburban community (Tucker is a significant DeKalb County unincorporated community that incorporated as a city in 2016 — a northeast Atlanta suburb adjacent to Stone Mountain and Decatur; Tucker is one of the more rapidly growing DeKalb County suburban communities, with a significant tech and professional economy tied to the Atlanta metro; Tucker is home of a significant Indian-American and Korean-American professional community (Tucker is one of the more diverse northeast Atlanta suburbs with growing South Asian and East Asian American communities along the Memorial Drive and Lawrenceville Highway corridors)), a diverse DeKalb County community with a significant African-American, Indian-American, and working-class to professional suburban population, adjacent to Stone Mountain and Clarkston in the northeast DeKalb County corridor — draws its municipal water supply via the DeKalb County Water and Sewerage Authority. Water hardness in Tucker measures 111 mg/L — classified as moderately hard.
Tucker's moderate hardness reflects the northeast Atlanta DeKalb County Chattahoochee Piedmont watershed's calcareous-poor geology with distribution variation. The Chattahoochee River (Lake Lanier) at Tucker–DeKalb County drains the Precambrian Georgia Piedmont gneiss (calcareous-poor). DeKalb County Water treatment produces the moderate 111 mg/L.
At 111 mg/L, Tucker residents encounter moderate scale accumulation. Monthly cleaning is recommended. DeKalb County Water and Sewerage Authority consistently delivers water meeting all Georgia EPD and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Chattahoochee River (Lake Lanier watershed) via the DeKalb County Water Authority — the DeKalb County northeast Atlanta Tucker corridor (Precambrian calcareous-poor Piedmont Georgia gneiss — the calcareous-poor northeast Atlanta Chattahoochee Piedmont watershed; effective treatment); moderately hard supply at 111 mg/L in DeKalb County.
