Triple isotope variations of monthly tap water in China.

ABSTRACT: Tap water isotopic compositions could potentially record information on local climate and water management practices. A new water isotope tracer ¹⁷O-excess became available in recent years providing additional information of the various hydrological processes. Detailed data records of tap water ¹⁷O-excess have not been reported. In this report, monthly tap water samples (n = 652) were collected from December 2014 to November 2015 from 92 collection sites across China. The isotopic composition (δ²H, δ¹⁸O, and δ¹⁷O) of tap water was analyzed by a Triple Water Vapor Isotope Analyzer (T-WVIA) based on Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS) technique and two second-order isotopic variables (d-excess and ¹⁷O-exce
