What Makes Sherwood's Water Unique?
Local geology and source profile
Sherwood, Arkansas, in Pulaski County — a major north Little Rock suburban community (Sherwood is a significant Pulaski County city — one of the primary north Little Rock suburban communities, a rapidly growing city adjacent to Little Rock Air Force Base (one of the most important US Air Force airlift installations — LRAFB is home of the C-130 Hercules tactical airlift mission for the 19th Airlift Wing, one of the primary Air Force cargo operations in the United States); Sherwood's proximity to Little Rock AFB makes it one of the most significant military commuter communities in Arkansas), a diverse Pulaski County community with a significant military and veteran, African-American, and working-class suburban population, adjacent to North Little Rock in the north Pulaski County corridor, home of significant retail development along US-67, and one of the rapidly growing north Little Rock metro communities — draws its municipal water supply via Central Arkansas Water. Water hardness in Sherwood measures 134 mg/L — classified as moderately hard.
Sherwood's moderate hardness reflects the central Arkansas Pulaski County Arkansas River supply's calcareous-moderate geology. The Central Arkansas Water distributes Lake Maumelle and Arkansas River supply to the northeast Pulaski County Sherwood zone, producing the moderate 134 mg/L.
At 134 mg/L, Sherwood residents encounter moderate scale accumulation. Monthly cleaning is 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 Sherwood corridor (Pennsylvanian calcareous-moderate Arkansas Valley shale and Ordovician calcareous-moderate Arkansas Ozark Plateau limestone — the calcareous-moderate central Arkansas Arkansas River Valley; CAW Sherwood northeast Pulaski distribution); moderately hard supply at 134 mg/L in Pulaski County.
