Naphthalene
Sunbelt Fresh Water Supply District High Meadows Subdivision
NOTE: Sunbelt Fresh Water Supply District High Meadows Subdivision purchases water from City of Houston which is required to test for naphthalene. Sample information shown below was taken by City of Houston.
Naphthalene is a polycyclic aromatic hydrocarbon, or PAH, released from combustion of fossil fuels and waste incinerators, and also used as a moth repellent. PAHs increase the risk of cancer; damage the immune, nervous and reproductive systems; and can harm developing fetuses.
