What Makes New Iberia's Water Unique?
Local geology and source profile
New Iberia, Louisiana, the Iberia Parish seat — a major south Louisiana Cajun Acadiana city (New Iberia is the Iberia Parish seat and one of the most culturally distinctive cities in Louisiana — a major center of Cajun culture in the heart of the Acadiana region; New Iberia is particularly famous for Tabasco sauce (the McIlhenny Company — makers of the iconic Tabasco hot sauce — has been producing Tabasco on nearby Avery Island since 1868; the Avery Island pepper sauce factory and gardens are one of the most visited attractions in south Louisiana)), home of Shadows-on-the-Teche (one of the most important antebellum plantation houses in Louisiana — a National Trust for Historic Preservation Historic Site on the banks of Bayou Teche), famous for its Cajun and Zydeco music culture (New Iberia is one of the most important Zydeco music communities in Louisiana), and a diverse Iberia Parish community with a significant Cajun-French, African-American, and Hispanic-American population — draws its municipal water supply from the Bayou Teche via the City of New Iberia Water Division. Water hardness in New Iberia measures 71 mg/L — classified as moderately soft.
New Iberia's moderate softness reflects the south Louisiana Bayou Teche coastal plain's calcareous-poor alluvial geology. The Bayou Teche drains Quaternary Mississippi River alluvial deposits (calcareous-poor coastal plain sediments). City of New Iberia treatment produces the moderately soft 71 mg/L.
With hardness at 71 mg/L, New Iberia residents enjoy moderately soft water. City of New Iberia Water Division consistently delivers water meeting all Louisiana DEQ and EPA Safe Drinking Water Act requirements.
