What Makes Hawaiian Paradise Park's Water Unique?
Local geology and source profile
Hawaiian Paradise Park, Hawaii, in Hawaii County — a Hawaii County unincorporated community adjacent to Keaau and Pahoa on the east side of the Big Island — receives its water from the Hawaii County Department of Water Supply, drawing from deep basaltic aquifer wells in the Kilauea volcanic rift zone through the east Hawaii Island distribution.
The soft 57.5 mg/L hardness and TDS of 172.8 mg/L reflect the Hawaii County Kilauea Basalt volcanic aquifer's soft character — the Holocene Kilauea Basalt and Pleistocene Mauna Kea Basalt are both highly insoluble tholeiitic basalt formations, and Hawaiian volcanic aquifer water reflects pristine Pacific rainwater that has percolated through nearly mineral-free olivine basalt (compare Keaau HI: 55/166 in Hawaii County comparable; Pahoa HI: 59/178 in Hawaii County comparable; Hawaiian Paradise Park consistent soft from the same Hawaii County Kilauea Basalt volcanic aquifer). The Kilauea volcanic aquifer — Holocene Kilauea Basalt (insoluble — primary dilutant), Pleistocene Mauna Kea Basalt (insoluble — secondary dilutant), and Quaternary volcanic ash deposits (insoluble — minimal TDS).
At 57.5 mg/L with TDS 173, Hawaiian Paradise Park's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 1.2 ppt is exceptionally low — among the lowest in the US — reflecting the remote Pacific location and absence of major industrial or military contamination in east Hawaii. Review the Hawaii County Department of Water Supply's annual report.
Geology & Source: Hawaiian Paradise Park in Hawaii County draws from the Hawaii County Water on Kilauea Basalt wells (Hawaii County, east Big Island, Hawaii) — the Kilauea volcanic aquifer at Hawaii County is developed in Holocene Kilauea Basalt (insoluble) and Pleistocene Mauna Kea Basalt (insoluble) — Hawaii Hawaii County Kilauea Basalt volcanic aquifer produces soft water at 57.5 mg/L with TDS 172.8 mg/L.
