This data set contains stable isotope values of tap water collected in the Salt Lake Valley (SLV) from 2013 to 2016.

The proposed goals for the project was to:
1. Characterize tap water isoscapes across SLV to develop isotope budgets for tap water systems.
2. Use the budgets and infrastructure data to infer the most important contributing regions to different municipal systems and evaporative water loss from these systems.
3. Combine management data, isotope characterization of environmental waters, and tap water isotope data to develop isotopic fingerprints for contrasting water management practice

Data Collection Methods: Collected tap water from different municipal districts across the SLV in a series of bi-annual hydrological surveys. The samples are collected from local businesses, homes and offices in April and September/October every year since 2013.The survey was designed in hydrologically contrasting seasons to capture potential seasonal differences in the tap water isotopes.

Location of Data Collection: We have collected data from approximately 140 sites every survey so far. The sites are located within the Salt Lake county, Utah. So far we have collected more than 800 samples. Each site is assigned a unique site ID (for example: SLV-WS-049 which stands for Salt lake valley water site number 049). The metadata includes the complete address and geographic location of the sites.

Timing of Data Collection:
April (04/25/2013) and October 2013 (10/02/2013)
April (04/29/2014) and September 2014 (09/25/2014)
April (04/28/2015) and September 2015 (09/28/2015)
April (04/27/2016) and October 2016 (10/01/2016)

Data Analysis: For each site, samples were obtained by running the tap water for ~15 seconds before filling, capping and sealing (with parafilm) a clean 4 ml glass vial. Samples were analyzed for their isotopic composition within a few weeks of their collection at the Stable Isotope Ratios for Environmental Research (SIRFER), University of Utah, on Picarro L2130-i Cavity Ring Down Spectroscopy (CRDS) analyzer. All the sample values are reported using the δ notation, where δ=Rsample/Rstandard -1, R= 2H/1H and 18O/16O. Four injections of each sample were measured and corrected for memory effects, through-run drift, and calibrated to the VSMOW-VSLAP scale, using a suite of three laboratory reference waters (PZ: 16.9‰, 1.65‰; PT: -45.6‰, -7.23‰; UT: -123.1‰, -16.52‰; for δ2H and δ18O, respectively).

We published the results in Water resources research ( DOI: 10.1002/2016WR019104)
