While not all microorganisms are harmful to human health there are some that may cause diseases in humans These are called pathogens Pathogens present in water can be transmitted through a drinking water distribution system causing wa terborne disea A ES AN D P AUL F LL ISINFE CT IN G YO LL W ER SHO CK C ORINA ION THE SHOCK CHL ORINA TION PROCESS A standard treatment for sanitizing your well system is shock chlorination Guidelines for using this treatment safely and effectively are listed below coli or fecal coliform For disinfecting wells to control iron or sulfur bacteria lease contact your Environmental Health Officer or Public Health Inspector BEFORE YOU START 1 Store sufficient water to meet family needs for 24 hours including the wat Courses for Entry into the Doctor of Pharmacy [Pharm.D.] Program 8/2014 Chemistry General Chemistry I with lab - 4 - 5 hours General Chemistry II with lab - 4 - 5 hours a Organic Chemistry I with lab Chlorination OF WATER SUPPLIES WHY IS CHLORINE ADDED TO THE ATER? Chlorine is used as a disinfectant, that is, to kill harmful micro-organisms that may be present in the water supply and to prevent micro-orga Chlorination requires FeCl3 !!Iodine must be oxidized to form a more powerful I+ species (with Cu+ or peroxide) 16.2 Other Aromatic introduces acyl group, "COR !!Benzene with acetyl chloride yields 5-7. The radical mechanism explains why the bromination of butane results in a racemate.. When a hydrogen atom is extracted from butane by an attacking bromine atom, it does not matter which hydrogen is extracted, an achiral planar sp. Free Radical Reactions. Overview. 2.
