Emissions from building materials - concentration of micropollutants and heavy metals in stormwater runoff of two new development areas in Berlin (Germany)

This dataset includes concentrations of micropollutants (27) and heavy metals (7) for stormwater runoff from different sampling points at two test sites (A and B) in Berlin, Germany. Both sites are new development areas of similar size that were both constructed in 2017 (1 – 1.5 years prior to the start of the monitoring campaign). Composite samples of individual rain events were taken at three sampling points of each test site: façade runoff, roof runoff and corresponding stormwater runoff from the catchment area. Samples were taken as part of the research project BaSaR (www.kompetenz-wasser.de/en/forschung/projekte/basar/) of Kompetenzzentrum Wasser Berlin, Ostschweizer Fachhochschule and Berliner Wasserbetriebe. More information including sampling and analytical methods are detailed in the corresponding journal paper "Emissions from building materials – a thread for the environment?", submitted to the MDPI-journal Water.

Description of fields:

SiteID: site identifier

A: new development site with typical architecture for multi-storey apartment buildings with plastered and painted facades in northern part of Berlin (124 apartments)

B: new development site with typical architecture for multi-storey apartment buildings with plastered and painted facades in southeastern part of Berlin (122 appartments)

SamplingPoint

facade runoff: runoff from plastered facade collected with gutters during individual rain events

roof runoff: roof runoff collected from one downpipe during individual rain events

storm sewer: stormwater runoff sampled during individual rain events in a manhole receiving runoff from the entire catchment (A or B)

LocalDateTime_StartRain: start time of sampled rain event (CET / CEST)

LocalDateTime_EndRain: end time of sampled rain event (CET / CEST)

CardinalDirection: only relevant for facade runoff

N: runoff from facade oriented to the north

W: runoff from facade oriented to the west

VariableName: name of analysed substance/parameter

CensorCode: either "lt" (less than) for concentration below detection limit (value is detection limit) or "nc" (not censored) for concentration above detection limit

UnitsAbbreviation: either "ug/L" (microgram per litre) or "mg/L" (milligram per litre)

DataValue: measured value (if censor code is lt, value indicates detection limit)

One data file is provided in comma separated format:
"BaSaR_data.csv" contains concentrations of all samples.
