reading a csv file in powershell , header line having duplicates

I have a script I am trying to read a csv file with and assign column names to the data. however the files has multiple columns named the same see below Grade QA/QC and Symbol

 ID,Date,Water Level / Niveau d'eau (m),Grade,Symbol / Symbole,QA/QC,Discharge / Débit (cms),Grade,Symbol / Symbole,QA/QC 07QC008,2018-12-28T00:00:00-06:00,6.536,,,1,0.052,,,1 

here is the code below, how can I modify it to maybe strip out the header row and susbstitute my ow columns names?

$  stations = import-csv “C:\Users\robm\Downloads\stations\SK_hourly_hydrometric.csv” #$  stations | Get-Member   ForEach ($  station in $  stations){ $  ID = $  ($  station.ID) $  Date = $  ($  station.Date) $  WaterLevel = $  ($  station."Water Level / Niveau d'eau (m)") $  GradeWL = $  ($  station.Grade1) $  SymbolWL=$  ($  station."Symbol / Symbole1") $  QAWL=$  ($  station."QA/QC1") #$  Discharge=$  ($  station."Discharge / Débit (cms)") $  Discharge=$  ($  station."Discharge") $  GradeD=$  ($  station.Grade2) $  SymbolG=$  ($  station."Symbol / Symbole2") $  QAD=$  ($  station."QA/QC2") Write-host $  ID "|" $  Date "|" $  WaterLevel "|" $  GradeWL "|" $  SymbolWL "|" $  QAWL "|" $  Discharge "|" $  GradeD "|" $  SymbolG "|" $  QAD #Write-host $  Discharge }
