What Makes Chamblee's Water Unique?
Local geology and source profile
Chamblee, Georgia, in DeKalb County — a major northeast Atlanta inner suburb (Chamblee is a significant DeKalb County city — an inner northeast Atlanta suburb adjacent to Doraville and Brookhaven; Chamblee has undergone a remarkable demographic transformation since the 1990s and is now one of the most ethnically diverse communities in Georgia; Chamblee is known as the 'Chambodia' and 'Little Saigon' of Atlanta (Chamblee has one of the most significant Southeast Asian-American communities in the Southeast United States — Vietnamese-American, Cambodian-American, and Korean-American businesses, restaurants, and community institutions are concentrated along Buford Highway in Chamblee and adjacent Doraville; the Buford Highway corridor in Chamblee–Doraville is celebrated as one of the most diverse and authentic Asian and Latin American food destinations in the United States)), home of the Antique Row (one of Atlanta's most well-known antique furniture and home goods shopping districts), a diverse DeKalb County community with a significant Hispanic-American, Vietnamese-American, and Korean-American population — draws its municipal water supply via the DeKalb County Watershed Management. Water hardness in Chamblee measures 150 mg/L — classified as moderately hard.
Chamblee's moderate hardness reflects the northeast Georgia DeKalb County Chattahoochee watershed's calcareous-poor Piedmont geology with distribution variation. The Chattahoochee River at Chamblee–DeKalb County drains the Precambrian Georgia Piedmont gneiss (calcareous-poor). DeKalb County Watershed Management treatment produces the moderate 150 mg/L.
At 150 mg/L, Chamblee residents encounter moderate scale accumulation. Monthly cleaning is recommended. DeKalb County Watershed Management consistently delivers water meeting all Georgia EPD and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Chattahoochee River (Buford Dam watershed) via the DeKalb County Watershed Management — the DeKalb County northeast Georgia Atlanta suburban Chamblee corridor (Precambrian calcareous-poor Georgia Piedmont gneiss — the calcareous-poor northeast Georgia DeKalb County Chattahoochee Piedmont watershed; effective treatment); moderately hard supply at 150 mg/L in DeKalb County.
