E16 Sandvika-Wøyen - Etterundersøkelser av vannkjemi og biologi 2021

Abstract

NIBIO gjennomførte etterundersøkelser av vannkvalitet, bunndyr og fisk i Sandviksvassdraget etter ferdigstilling av ny vei mellom Sandvika og Wøyen i 2021. Vassdraget har tidvis hatt noe økte konsentrasjoner av næringsstoffer og havner innenfor «moderat» tilstand basert på totalnitrogen, men tilstanden er ikke forandret fra forundersøkelsene. Konsentrasjonene av de undersøkte tungmetallene var lave og innenfor «god» eller «svært god» tilstand. Bunndyrprøvene viste «moderat» økologisk tilstand. Fiskeundersøkelsene viste «svært god» tilstand for ungfisk av laksefisk både i 2020 og 2021, selv om tettheten var betydelig lavere i 2021 enn i 2020. Samlet sett viser etterundersøkelsene at utbyggingen ikke har hatt vesentlig påvirkning på undersøkt vannkjemi eller biologi i Sandvikselva.
