ENVIRONMENTAL PROBLEM TARGETED

The Barlad River Basin represents 17% of the surface of Siret river basin, which is the biggest Romanian river basin, characterised by a great number of agricultural sources and nitrate vulnerable zones. The report on water quality from 2007 year of the Barlad river basin (surface of 7220 km², mean altitude 211 m) show high concentrations of ammonium, organic matter and nutrients in the downstream part of the basin. The first designation of the vulnerable zones in 2003 year shows there are 7 villages (35602 habitants from which 100% reject the wastewater directly in the soil) proposed as vulnerable zones, characterized by ne sewage systems and no wastewater treatment plants. The second designation of vulnerable zones in 2008 is based on the nitrate measurements from both designated vulnerable zones and potentially vulnerable zones proposed in 2003 year.

The results show that in the Barlad river Basin there are much more vulnerable zones - 47 villages - meaning almost 37% of the river basin area.

From a total of 207 km length, the Barlad River presents the last 116 km as being "at ecological risk" from the nutrients pollution point of view.

Human activities (surface discharge, especially from the chemical industry field; agricultural infiltration; wastewater infiltration, through not treated domestic effluents directly discharged by the population not connected to the sewage system) have disturbed the natural fluxes between the nitrogen and phosphorous, resulting in increased nutrient levels (ammonium and nitrates) in surface and ground waters (e.g. downstream of Negresti city nitrate concentration is bigger than 50 mg/l). The economical units with a great pollution weight are SC Pui Prod SRL Lipovat, SC Rulmenti SA Barlad and SC Ianis Oil SRL Berheci, being included in the first 12 pollution sources of the Siret River Basin. At the river basin level there are only 6 wastewater treatment plants which have functioned improperly and are not appropriate with the European legislation requirement. The rest of localities, meaning more than one hundred, has no sewage system and waste water treatment plants

The groundwater quality is also affected by the interaction with surface waters. The hydrogeological wells from the national monitoring network show an exceeding of ammonium, nitrates and phosphates in the neighbourhood of several villages such as: Matca, Corod, Munteni, Ivesti etc.
