Dibromochloropropane, or DBCP, is a pesticide introduced by the Dow Chemical Company and Shell Development Company in 1955 in order to control nematodes, or root worms, at the base of pineapple plants. However, by 1984, when DBCP was finally phased out in Hawai`i, it would cause damage to more than just nematodes. Although DBCP was initially thought to dissolve in soil, it instead percolated into the groundwater, and contaminated the drinking water supply in Hawai`i [2;5]. DBCP is in the persistent organic pollutants class of pesticides, which remain in the environment for long periods of time and can be harmful to human health . By 1977, DBCP was known to be harmful, and was banned in California after it was discovered to cause cancers in test animals, and that workers exposed to DBCP were experiencing infertility . DBCP has also been linked to kidney and liver damage, infertility and potentially cancer .
