title: Organic micropollutants and heavy metals in stormwater runoff of five different catchment types in Berlin (Germany)

description: This dataset includes concentrations of micropollutants (67), heavy metals (8) and standard parameters (9) for stormwater runoff taken from separated sewers of five catchments between 3 and 37 ha in Berlin (Germany). It also includes rain data of analyzed events as separate file. Samples were taken as part of the OgRe research project of Kompetenzzentrum Wasser Berlin (www.kompetenz-wasser.de/en/project/ogre/) in 2014 and 2015. Sampling and analytical methods are detailed in "Concentrations of micropollutants in urban stormwater runoff of different land uses" (https://doi.org/10.3390/w13091312). A dataset with concentrations of the urban stream Panke in Berlin during dry and wet weather (samples were taken as part of the same project) is available separately (https://zenodo.org/record/4633779). <strong>Description of fields (concentrations):</strong> <strong>SampleID</strong>: unique sample identifier <strong>SiteID</strong>: unique site identifier (catchment type) 1 - OLD: area with typical five-storey perimeter blocks built between 1870 and 1930 (31 ha) 2 - NEW: newer area of 4-8-storey concrete slab buildings built between 1960 and 1980 (16 ha) 3 - STR: 1.3 km of a busy streeat with intersection with traffic lights and bus stops (3 ha) 4 - OFH: a residential area characterized by one-family houses and villas with gardens (17 ha) 5 - COM: a commercial and industrial area of high imperviousness with large flat-roof buildings and yards (37 ha) 6 - PNK: urban stream Panke (characterized by strong stormwater inputs from separate sewer discharges - available in separate dataset) <strong>LocalDateTime</strong>: start time of sampling (local) <strong>DateTimeUTC</strong>: start time of sampling (UTC) <strong>UTCOffset</strong>: UTC offset to local time in h <strong>SampleType</strong>: either "composite" for volume proportional composite sample (all samples from storm sewers) or "single" for grab sample (all stream samples, separate dataset) <strong>VariableName</strong>: name of analysed substance/parameter <strong>UnitsAbbreviation</strong>: either "ug/L" (microgram per litre) or "mg/L" (milligram per litre) <strong>CensorCode</strong>: either "lt" (less than) for concentration below detection limit (value is detection limit) or "nc" (not censored) for concentration above detection limit <strong>DataValue</strong>: measured value (if censor code is lt, value indicates detection limit) <strong>Description of fields (rain data):</strong> <strong>SampleID</strong>: sample identifier of matching sample (see above) <strong>SiteID and SiteName</strong>: unique site identifier and name (catchment type) (see above) <strong>tBeg_rain, tEnd_rain</strong>: begin and end of rain event in local time <strong>depth.mm</strong>: rain depth of rain event in mm <strong>duration_rain.h</strong>: duration of rain event in h <strong>intensity_max_10min.mm_h</strong>: maximum rain intensitity of rain event in 10-min interval in mm/h <strong>intensity_mean_event.mm_h</strong>: mean rain intensitity of rain event in mm/h <strong>ADD.d</strong>: number of antecedent dry days in days Rain data was collected by rain gauge network of Berlin waterworks (&gt;40 gauges) — gauge with best correlation between rain depth and event volume in storm sewer was chosen (distances to monitoring sites: 2–6 km). Two data files are provided in comma separated format: "OgRe_drain.csv" contains concentrations of all stormwater runoff samples taken in separate storm sewers "OgRe_rain.csv" contains rain data for all stormwater runoff samples
