20 Hidrológiai Közlöny 1977. 1. sz. Mátrai István: A magyar vízügyi nagylétesítmények The monitoring stations have been equipped for the observation and relaying of the following 8 water quality parameters

: —- temperature (Aquadat) — dissolved oxygen (Aquadat) — pH (Aquadat) — conductivity (Aquadat) — turbidity (Nephelon) — total organic substance (Okometer) — oil content (Oil test) — iron content (Aquanal). In addition to the monitoring stations built along the Sajó River under the Project, the competent district water authority has started the expansion of the network on the streams in the areas under its jurisdiction. All data are transmitted to the Regional Center established at Miskolc. The purpose of these stations is the continuous registering of water quality parameters, the detection of occasional pollution surges and the indication thereof, whenever particular water quality limits are exceeded. The layout of the regional center in the Sajó Quality Control System (SYR) is shown in Fig. 6. The equipment includes the micro-computer needed for operating the system, the data-transfer and entry equipment, further the dispatching board indicating and displaying the water quality parameters. The results of the Project are expected to materially contribute to the development and improvement of water quality control both in Hungary and abroad. Within the next two decades construction work will be terminated on the basic system of major projects controlling fundamentally the quantitative distribution of water supplies in Hungary. The most economical system for controlling the quality of waters must be related closely to the quantitative distribution system of supplies. Allowance must be made for the greatest polluting load which a particular ecosystem is capable of assimilating, for the least detrimental methods of disposing the polluting- and waste substances in the recipient streams and in the soil, with due regard also to the reclamation of the valuable substances contained in the "pollutants". The eight countries situated along the Danube are anticipated to complete construction on the Danube dams by the end of the century. These dams will bring about radical changes in the original conditions, an accelerated rate of socioeconomic evolution and, in turn, considerably increased hazards of water pollution. For this reason close cooperation is considered essential between the countries interested in environment protection and particularly in controlling the quality of waters. The results of the Project HUN/PIP001 are expected to contribute under the Environmental Program of the UN and by cooperation of the Danube states to the realization of the efforts contemplated with the aim of improving the quality of Danube water.
