Point and nonpoint sources of nutrients to lakes - ecotechnological measures and mitigation methodologies - case study

Presently, 1514.4 and 150.5 t/year of total nitrogen and phosphorus, respectively, enter Lake Egirdir from point and nonpoint sources. The successful implementation of projects that have been prepared for point sources may reduce total nitrogen pollution by 79% and total phosphorus by 30-50%. The nutrients that come from nonpoint sources, except from atmospheric deposition, can decrease by a minimum of 50% through effective control techniques.
