clean water
for hawai‘i. forever.

A pesticide legacy from Maui's pineapple and sugar plantation era. Banned in 1977 but still leaching into wells decades later. Causes male infertility, sterility, kidney cancer, and stomach cancer. Maui has documented DBCP contamination in multiple wells across the Pa‘ia Aquifer.

Originally an impurity in pineapple-field nematocides. A potent industrial solvent and probable human carcinogen. Linked to liver, kidney, and stomach tumors. Hawai‘i has some of the highest 1,2,3-TCP contamination in the United States — and it persists in groundwater for decades.

Linked to skin lesions, cardiovascular disease, diabetes, and cancers of the bladder, lungs, kidney, and skin. Long-term exposure even at low levels causes cumulative damage to the nervous system. Naturally occurring in volcanic groundwater and concentrated through agricultural runoff.

The "Erin Brockovich chemical." Causes lung, stomach, and intestinal cancer even at extremely low concentrations. California sets its health goal at 0.02 parts per billion — Maui's levels routinely exceed this. Damages liver, kidneys, and the reproductive system. Industrial pollution legacy.

Disinfection byproducts that form when chlorine reacts with organic matter in tap water. Associated with bladder, colon, and rectal cancer. Linked to fetal growth issues, miscarriage, and birth defects in pregnant women. Absorbed through skin during showering.

Carcinogenic disinfection byproducts. The EPA regulates HAA5 because of strong links to cancer of the bladder, colon, rectum, and esophagus, plus liver and kidney damage with chronic exposure. Found exceeding health guidelines across the Iao Aquifer system.

A family of disinfection byproducts including chloroform and bromoform. Linked to bladder cancer, colorectal cancer, and adverse reproductive outcomes. Absorbed through skin and lungs during showering — making whole-home filtration essential, not just under-sink drinking water filters.

Classified as a probable human carcinogen. Associated with kidney and liver cancers, and reproductive problems including miscarriage. Forms during chlorination of water containing natural organic matter — and Hawaiian groundwater is rich in organic matter.

Animal studies indicate that long-term intake causes liver and kidney cancer. Damages the central nervous system and is linked to spontaneous abortion in pregnant women. Forms when bromide-containing water is chlorinated — common in coastal aquifers.

From decades of fertilizer runoff into Maui's groundwater. Causes "blue baby syndrome" (methemoglobinemia) in infants — a potentially fatal condition. National Cancer Institute research links elevated nitrate to bladder cancer and thyroid disease in adults.

Causes liver tumors in animal studies and is classified as possibly carcinogenic to humans. Linked to neural tube defects in newborns when mothers are exposed during pregnancy. Crosses skin and lung barriers easily — exposure happens with every shower.

A heavy metal that leaches into Maui groundwater from volcanic rock and industrial sources. Linked to high blood pressure, kidney damage, gastrointestinal distress, and developmental problems in children. Bioaccumulates in the body over time with continuous exposure.
