The composition of groundwaters of Muraviov-Amursky Peninsula, Primorye, Russia

Abstract

Seawater intrusion, composition and quality of the shallow ground water in the south of Primorye region had been investigated. The Muraviov-Amursky peninsula is a middle mountain area (up to 400 m). The rocks in this area are presented by Permian volcanic, sedimentary, and granite rocks as well as Triassic sediments. Water had been included in a fracturated zone. The water table is located at depths ranging from less than 1 meter to more 20 m. The changes is depending on seasonal and atmospheric precipitation that varies between 1000-1200 mm/y. Values of pH ranging from 5.4-8.4, main ions composition is mixed with HCO₃-Ca, Na – in granite rocks. Sea water intrusions had been examined by chemical and stable isotopes data.
