What Makes Jacksonville's Water Unique?
Local geology and source profile
Jacksonville, Arkansas, in Pulaski County — a major central Arkansas Little Rock suburban military community (Jacksonville is a significant Pulaski County city — adjacent to Little Rock Air Force Base (LRAFB — one of the most important US Air Force installations in the South; LRAFB is the home of the 19th Airlift Wing, one of the Air Force's premier C-130 Hercules transport aircraft operations; LRAFB is also home of the 189th Airlift Wing of the Arkansas Air National Guard)), a diverse Pulaski County community with a significant military and veteran, African-American, and working-class suburban population, adjacent to Cabot and North Little Rock in the central Arkansas Pulaski County corridor, home of significant Jacksonville retail and residential development as the Little Rock metro area expands north and east, and a community shaped by its Air Force base identity — draws its municipal water supply via the Central Arkansas Water. Water hardness in Jacksonville measures 157.5 mg/L — classified as hard.
Jacksonville's hard supply reflects the central Arkansas Pulaski County CAW distribution zone's calcareous-moderate character. The Central Arkansas Water distributes Lake Maumelle supply to the northeast Pulaski County Jacksonville zone with limited softening, producing the hard 157.5 mg/L.
At 157.5 mg/L, Jacksonville residents face regular hard water challenges. Monthly descaling and water softeners are recommended. Central Arkansas Water consistently delivers water meeting all Arkansas DEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Arkansas River (Lake Maumelle watershed) via the Central Arkansas Water (CAW) — the Pulaski County central Arkansas Little Rock suburban Jacksonville corridor (Pennsylvanian calcareous-moderate Arkansas Valley shale and sandstone — the calcareous-moderate central Arkansas River Valley CAW distribution; limited softening); hard supply at 157.5 mg/L in Pulaski County.
