The urbanization of Shenzhen is mainly divided into three phases. Among the hydrochemistry data we collected from different institutes, 268 samples belong to Stage 1 (1980-1999), 414 samples belong to Stage 2 (2000-2010), and 59 samples belong to Stage 3 (2011-2020). These water samples include borehole water samples, civil well water samples, and several seawater samples, which can reflect the distribution of groundwater quality in different historical stages on the west coast of Shenzhen to a certain extent. In November 2019, we collected 32 water samples additionally. A portable multi-parameter HACH Water Quality Analyzer (HQ40D) was used to measure the pH, temperature, dissolved oxygen (DO) concentration, and electrical conductivity (EC) of the water samples on-site. The alkalinity was titrated with hydrochloric acid in the field. The water samples for cation measurements were acidified by concentrated hydrogen nitrate before being sealed in sampling bottles. Then these water samples were sent to the School of Environmental Studies at China University of Geosciences and the Three Gorges Research Center for Geohazards, Ministry of Education, China for analysis. The hydrochemistry data of all 773 water samples were for the investigation of groundwater salinization due to the seawater intrusion on the West Coast of Shenzhen, Guangdong Province, China.
