    Chemical Analysis of Water Water Analysis of Sample taken from No. 17 Borehole at Hazon Fora before Chlorination, 2nd September. .1254 Chemical Results Parts per 100 .000 Total solids dried at 180°C Chlorine as chlorides Free ammonia Albuminoid ammonia Nitrogen as nitrates Oxygen absorbed (4 hours at 80°F) Total hardness Permanent hardness Temporary hardness Lead and copper Iron Appearance and colour (Hazon degrees 20) Pale Smell and taste Micrcspopicul examination of deposit pH value Free Carbon Dioxide Report Dissolved Oxygen 333 28.4 0.08 0.03 trace 0.2 228 nil 228 none 1.3 yellow & slightly cloudy Sightly earthy- see report. 6.6 This sample of borehole water Is of satisfactory organic purity, the somewhat high free ammonia being character- istic of many borehole waters, and the other constituents give no indication of pollution. The water is somewhat cloudy and microscopical examinati r of the deposit shows it to be almost entirely mineral matter, mostly ferric oxide. The pH value is low and the water is probably corrosive to metals, but aeration would odidise the iron, if it is inherent in the water, and raise the PH value by discharging some of the free carbon dioxide. The sample is somewhat similar to that examined In October last, but it contains no permanent hardness, the pH is low and the free ca-bon dioxide is higher. Bacteriological Examination Thirty two bacteriological examinations of the water wor^ made throughout the year. 3/5/54
