Derfor blev Bagå forurenet

Man har nu draget konklusion fra de vandprøver, som blev taget i Bagå på baggrund af forureningen som ramte åen i tidligere på måneden.

Teknik & Miljø kan konstatere, at det var valle som forårsagede forureningen, som dræbte mange fisk. Valle udskilles som følge af osteproduktion og bruges til at fodre

grise i landbrug.

“Det indeholder jo en hel masse stoffer fra mælken, blandt andet en masse laktose, mælkesukker, og når det kommer ud i vandet, så bliver det omsat af bakteriefloraen i vandløbet under iltforbrug, meget kraftig iltforbrug, og det vil sige, at alt ilten i vandet bliver brugt til at omsættte det her mælkesukker”, siger Henrik Jespersen, biolog ved Bornholms Regionskommune, ifølge TV2 Bornholm.

Man tror at den udskilte valle, som forårsagede iltmangel i åen, stammede fra Simlegård i Klemensker, som gennem en rørledning er endt i vandet.
