What Makes Mansfield City's Water Unique?
Local geology and source profile
Mansfield City, Connecticut, in Tolland County (Capitol Planning Region) — a major northeast Connecticut University of Connecticut community (Mansfield is a significant Connecticut town — the home of the University of Connecticut main campus (UConn Storrs — one of the most important public research universities in New England; UConn is the flagship state university of Connecticut with approximately 19,000 undergraduate students; the UConn campus in Mansfield–Storrs is a major comprehensive research university with strong programs in pharmacy, law, business, and engineering; UConn's Division I athletic programs — particularly basketball (the UConn Huskies — one of the most celebrated programs in college basketball history; the UConn women's basketball program under Geno Auriemma has won 11 national championships and is widely considered the greatest dynasty in women's college sports history) — are among the most accomplished in the country)); Mansfield is the home of Storrs, the village at the heart of the UConn campus, and is a strongly university-dominated community — most of Mansfield's economy, population, and character revolves around the university, making it one of the most purely university-dominated communities in New England, a diverse Capitol Planning Region community with a primarily UConn student, faculty, and staff population — draws its municipal water supply via the Mansfield City Water Division. Water hardness in Mansfield City measures 41.5 mg/L — classified as soft.
Mansfield City's soft supply reflects the northeast Connecticut Tolland County Fenton River watershed's calcareous-poor crystalline geology. The Fenton River watershed drains the Precambrian Connecticut gneiss (calcareous-poor). Excellent treatment produces the soft 41.5 mg/L.
With hardness at 41.5 mg/L, Mansfield City residents enjoy soft water with no scaling concerns. Mansfield City Water Division consistently delivers water meeting all Connecticut DEEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Fenton River watershed via the Mansfield City Water Division — the Capitol Planning Region northeast CT Mansfield corridor (Precambrian calcareous-poor CT Windham County crystalline gneiss — the calcareous-poor northeast CT Mansfield Fenton River watershed; excellent treatment); soft supply at 41.5 mg/L in the Capitol Planning Region.
