SUMMARY
In this study, the quality of municipal water Nessonos as those used for water supply and for irrigation. In samples taken regular sampling approximately one per month over one year (March 2004 to March 2005) studied the basic properties that characterize the water on both uses (pH, electrical conductivity, concentration of sodium, calcium, magnesium, chlorine, nitrate, boron and heavy metals) and their quality was evaluated based on international standards. The results showed that in terms of water intended for drinking, all the benefits are of good quality water.
The only drilling shows somewhat increased concentration of nitrates reaching the target price level and requires monitoring the water supply Sikourio. In the case of drilling at "Cemetery" and at "N24" nitrates seems not derived from inorganic fertilizers, but organic nitrogen sources, while at "V31" nitrogen sources are mixed. The pH was within acceptable (7.0-8.5), the hardness was found to range generally between 120 - 150 ppm CaCO3 and the chlorine concentration was much lower than the upper permissible limit (350 ppm).
As regards the water for irrigation in all cases ( except for one ) the electrical conductivity was less than 0.70 mmhos / cm ( or 700 mmhos / cm) characterized as " good." The exception is drilling at " L72 " of the municipal district of Kalochori , the waters of which the value of electrical conductivity exceeded 700 mmhos / cm.
Chlorine concentration in all contexts was lower limits for all types of irrigation (140 ppm for surface irrigation and 105 ppm for drip irrigation ) . The boron concentration was also very low ( much less than 0.7 ppm) except drilling at " saltiness " of elementary Sikourio compartment amounted to 1 ppm. As to the concentration of bicarbonate water classified as " small to moderate restriction .
