/*Perchlorate*/ is an inorganic chemical used in solid rocket propellant, fireworks, explosives, flares, matches, and a variety of industries.
Residents were told not to boil the water, as that process does not reduce the chemical level. Boiling, freezing, filtering or letting water stand does not reduce the levels of perchlorate in the water. Boiling water can actually increase the concentration of the chemical in the water by reducing the H2O content.
Residents were advised Barstow water may still be used for non-drinking purposes, such as showering and washing.
