Kashafroud River watershed is located in Khorassan Razavi province (Northeast of Iran). This river emanates from Hezar Masjid and Binaloud Mountains pass through out Mashhad plain, enters to Turkmenistan and joins to the Harirroud River. Biological and chemical analyses of Kashfroud River water shows amount of Nitrate have been increased along the towns and villages. Considerably this amount of Nitrate is more than the standards. Studies show human, industrial and agriculture waste water cause physical, chemical and biological pollutions and as a result increase amount of Nitrate in water. Famous disease that is known for high density of nitrate in drinkable water is Methaemoglobinemia and Cyanosis.
