Las Vegas - April 30* 1953 oo* R* L. Adamson - Los Angeles During the past two weeks the Health Department, Las Vegas, has reported quite a few looations where water analysis has indioated contamination in the southern and southeasterly portion of the oity. When these reports were received, it became necessary for me to take steps to correct the situation— which was done by the means of the introduction of chlorine into the system at the wells and at the Charleston Boulevard Reservoir for several d$ys during the past week* The condition reported by the Health Department last week has now been entirely cleared up* New samples were taken last Tuesday morning and reports from the Health Department today, which are in my possession, Indicate that the water at each of the locations where contamination was previously reported is now entirely free of contamination. This is no doubt due to action taken immediately after contamination was reported to me* In connection with the work of introducing chlorine into the water mains, I find that the facilities at hand are very crude and unsatisfactory from the standpoint of efficient operation* This applies not only to the Water Company1s equipment, but to the Railroad Company's equipment. From the Water Company's side, we have a pres­sure pump, which pumps chlorine directly into the main from a chlorine solution previously prepared* This operation requires that a man be kept on the Job throughout the 2 k hour period to regulate the flow of chlorine into the main in order to prevent the introduction of Mr, Wm.
