Monitorizarea calitaţii apei destinate consumului uman

In Romania, water intended for human consumption is obtained from surface water (90-92%) and underground water resources, and the existent systems of water supply cover only 65% of population consumption (97% for urban population). Under EEA Financial Mechanism, INCD ECOIND and STIFTELSEN SINTEF (Norway Company) will developed in partnership a project for monitoring potable water quality (from catching until production and distribution) supplied by two Romanian companies, which have, at regional level, monopoly on services of potable water production and distribution for at least 100,000 inhabitants. The potable water quality monitoring duration was 12 months, over 1400 samples were taken from 185 sampling points: catchment (raw water), technological flows, plant exit, from storage tanks and from networks distribution to final consumers. For each sample, physical, chemical and bacteriological monitoring was performed according to national and European regulations. The analytical results showed that, at most treatment plants the concentration of free chloride, trihalomethanes, aluminium, iron, zinc, sulphur and ammonium exceeded the limits at all times, while turbidity, nitrate, organic matters and manganese were sporadically detected. Regarding microbiological quality of monitored potable water, we observed the presence of mesophile bacteria at 220C and 370C, and in some water treatment plants Clostridium perfringens and Pseudomonas aeruginosa were detected. The expected results of the project are: optimization and implementation of appropriate water quality monitoring program from producer to final consumers; improvement of the actual methods of analysis and implementation of new methods for conformity to the requirements for potable water quality control; optimization of analytical control schemes; measures for optimization of the actual flows of water treatment / potabilization; recommendations for arrangement/maintenance/control of distribution network; knowledge and innovation transferred to other water treatment plants and water supply systems.
