140 Hoffmann I. —Tóth L. Experiences gained with the portable water quality analyser by I. HOFFMANN and L. TÓTH In order to solve the problems of water pollution control a growing number of analyses and rapid processing of the data are essential. In addition to the permanently mounted automatic water quality monitoring stations (Aquadat MMG), portable water quality analysers (e.g. the "Aquacheck OH —503" model made by the Hungarian RADELKIS Company, Hungary) are being applied in an ever expanding field. Of the investigations performed in the region of Lake Balaton, the results obtained in the littoral zone (Figs. 1 to 4), the stratification studies (Table I), the layer studies in fish ponds used for sewage disposal (Fig. 5), further the results of analyses related to the site selection of intakes from the lakes are described (Table II). The results of investigations into the thermal pollution caused by power stations in the Danube region are shown in Table III. The round 57 km long section of the Soroksár Danube Arm has been surveyed in less than eight hours, producing 558 data. Using the portable analyser the investigations on nine horizontal filter wells drawing on bank filtered water have been completed within 1 hour. The area of groundwater entrance has taken 3.5 hours to locate (Fig. 7). The investigations on the Komora Valley reservoir (Table V) and on the Kisköre reservoir (Fig. 8) produced results within a very brief period of time. Thus the Kisköre reservoir has been investigated by layers at 16 points, yielding 276 data in round three hours only.
