[A data processing system for bacteriological and chemical water analysis].

Abstract

Using the "Natural" computer language a menu-guided system for cataloguing, processing and evaluating bacteriological and chemical water analyses was designed. The program can be employed to different blocs of analyses, e.g. "TrinkwV"-analyses, standard-analyses, those on volatile chlorinated hydrocarbons and bacteriological water analyses as well. For each water sample the actual, the last and the next to the last value, also arithmetical means, minimal and maximal are stored and can be retrieved. The evaluation of the bacteriological analyses and those of the volatile chlorinated hydrocarbons is carried out by a choice of text variants, whereas the TVO- and standard-analyses are interpreted automatically. Managing laboratory data has become much easier during our three years experience using this system for information storage, search and retrieval in water research and routine; even untrained users are able to handle it after a short period of tuition.
