Abstract	:	The term heavy metal refers to any metallic element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), Selenium (Se), and lead (Pb). Heavy metals are natural components of the Earth's crust. They cannot be degraded or destroyed. To a small extent they enter our bodies via food, drinking water and air. Exposure to excessive concentrations of such elements has produced adverse effects on health. This work is concerned with the detection of heavy metals in drinking water through out old Jeddah water pipelines using laser induced break down spectroscopy (LIBS) and measure their concentrations along with the limit of detection of our system. Laser Induced Breakdown Spectroscopy (LIBS) is a capable tool for detection of heavy metals and other contaminants in solid, liquid, and gas samples. When a pulsed laser with an optimum energy is irradiated on the surface of a sample, a small amount of the sample is vaporized .The ejected material known as plume shows several emission line characteristics of the atoms or molecular species in it. The ability of LIBS to provide rapid multi-elemental microanalysis of samples in the parts-per-million (ppm) range with little or no sample preparation. LIB is very versatile for environmental chemical analysis because they offer real-time monitoring capabilities with high analytical sensitivity and selectivity.
