Marijampolės miesto geriamojo vandens kokybės dinamika 2005–2013 m

Abstract

2005–2013 in the city of Marijampole I-th and II-th waterworks were chemically analyzed water quality. According to the results suggest that drinking water quality is not all good indicators of water quality targets set . Marijampole‘s city waterworks water total iron concentration limit value is exceeded. Particularly high concentrations of total iron I-th found th wellfield 2011–2013 period. After the removal of iron artesian wells both waterworks total iron concentration was significantly reduced. Other research on water quality indicators does not exceed the water quality standards. Ammonium ion concentration did not exceed the limit value. Artesian wells in the mixture after removal of iron ammonium concentration decreased almost twice. Chloride concentration of permanganate index value, nitrate and nitrite levels in artesian wells in the mixture than one year does not exceed the limit value
