Some characteristics of underground water quality and ability to use water coastal plain Ha Tinh

Abstract

    This paper presents the results of hydrological survey and analysis of water parameters and the composition of water samples in underground water in the area, showing that most of underground water quality indexes are inside The limit allowed under QCVN 09: 2008/ BTNMT, QCVN 39: 2011/ BTNMT and QCVN 01: 2009/ BYT; There was an increase in chloride concentration, hardness and total dissolved solids (TDS) in the dry season; The ability to use water (pale and brackish water) in the area is quite good, but depends much on the rainy season and the influence of tides, so before using for different purposes, it is necessary to take technical measures standard allowed.
