REVIDERAT KONTROLLPROGRAM FÖR DAGVATTEN VID MALMÖ-STURUPS FLYGPLATS / Revised monitoring programme for storm water quality at the Malmö-Sturup airport
A monitoring program for stormwater quality from the Malmö-Sturup airport was ratified by the regional authority in 1989. The dominating source of water pollution from the airport is the chemicals monopropy-lenglycol, urea and potassium acetate, used during winter season for deicing of the aircraft’s and runways. The monitoring programme included 5 sampling stations with monthly sampling and analyses of 16 variables. In addition three storm water receiving waters were monitored every second month, with aim to identify effects of the storm water discharge. An evaluation of the monitoring activities for a time period of 10 years demonstrated many weaknesses of the programme. For instance: non-representative sampling stations; irrelevant variables; the same sampling frequency independent of season; difficulties/impossibility to unambiguously demonstrate recipient effects of the storm water pollution. A proposal for a modified programme was accepted in April 2002. The number of sampling stations has been reduced to two, one of which activated only during the deicing season. The number of variables analysed has been reduced to 8. The three sampling stations in the pollution receiving waters have been excluded from the airport monitoring programme.
