ion of water and discharge of effluents in Lithuania is regulated via permit system established by the Order of the Ministry of Environment on Issuing of Operational Permits (LAND 32–99). All abstractions of water greater than 10 m3/ day and discharge of effluents greater than 5 m3/day are subject to regulation via the permit system. In addition, these water users are required to supply statistical data about use of water and discharge of effluent to the Ministry of Environment. The quality of receiving waters in Lithuania is regulated by controlling the concentration of pollutants in effluents. The Order of the Ministry of Environment on Waste Water Pollution Standards (1995) sets requirements for the treatment of effluents (concentrations of nutrients and dangerous substances). The Waste Water Pollution Standards are currently under revision. Diffuse pollution of surface waters is controlled via the Regulation on Special Conditions for Use of Land and Forest (1992) and the Order of the Ministry of Environment and Ministry of Agriculture on Requirements for the Management of Manure and Waste Water at Farms (LAND 33–99). The State Environmental Monitoring Programme (1998) defines sampling points, frequencies, and parameters for monitoring of surface, ground and coastal waters.
