Survey of major and trace elements in stormwater runoff from across the United States, 2016 to 2017
Open accessAbstract
This study focuses on providing a broad-scale assessment of composition of water chemistry in urban stormwater runoff. The stormwater runoff is a source of recharge to groundwater by Green Infrastructure (GI) practices or it may become a source of recharge to groundwater to reduce stormwater volumes to surface waters or augment groundwater supply. The chemical composition of the stormwater runoff is important to understanding the potential impacts of surface water recharge to groundwater. In this study, 21 field sites were sampled for stormwater runoff during 50 storm events from 7/28/2016 through 12/8/2017. Major elements were measured by inductively coupled plasma-optical emission spectrometry and trace elements were measured by inductively coupled plasma-mass spectrometry. Each sample was analyzed in triplicate and the averages and standard deviations are reported. The results from analyses of associated quality assurance samples (field blanks, field duplicates, and average laboratory blanks) also are presented.

In general, inorganic chemical concentrations in urban stormwater samples were relatively dilute, as suggested by specific conductance values that ranged from 38 to 1,074 μS/cm (median 164 μS/cm) and low concentrations of trace elements, anions, and cations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
