What Makes Hyde Park's Water Unique?
Local geology and source profile
Hyde Park, Boston, Massachusetts — a major south Boston neighborhood (Hyde Park is one of Boston's southernmost neighborhoods — a distinctive south Boston community annexed from Canton and Dedham in 1868, the last neighborhood annexed by Boston; Hyde Park is known for its strong Irish-American and Italian-American heritage and is one of Boston's more residential and suburban-feeling neighborhoods), a diverse Suffolk County community with a significant Irish-American, African-American, Cape Verdean-American, and working-class population, home of the Ellis Memorial (one of Boston's significant community social service agencies), adjacent to the Charles River Reservation and the Blue Hills Reservation (one of the largest metropolitan park reservations in the Boston area), and a community in transition with significant demographic diversification — draws its municipal water supply via the Boston Water and Sewer Commission. Water hardness in Hyde Park measures 106 mg/L — classified as moderately hard.
Hyde Park's moderate hardness — significantly higher than Boston's typical MWRA supply (~50 mg/L) — reflects the south Boston BWSC distribution zone's older infrastructure. The BWSC distributes MWRA Wachusett supply through the Hyde Park south Boston zone (primarily late 19th–early 20th century south Boston development mains), producing the moderate 106 mg/L.
At 106 mg/L, Hyde Park residents encounter moderate scale accumulation. Monthly cleaning is recommended. BWSC consistently delivers water meeting all Massachusetts DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Wachusett Reservoir (MWRA system) via the Boston Water and Sewer Commission (BWSC) — the Suffolk County south Boston Hyde Park corridor (Precambrian calcareous-poor Wachusett granite and Quabbin granite — BWSC south Boston Hyde Park distribution zone; older south Boston infrastructure increasing hardness); moderately hard supply at 106 mg/L in Suffolk County.
