Assign group permissions on folders using Powershell via CSV

The following should get you what you need (make sure that the groups in your CSV match the name of the group in AD or it won't work correctly):

$Folders = Import-Csv "C:\Scripts\Folders.csv" -Delimiter ";" -Header "Path","List","Read","ReadWrite"

ForEach ($F in $Folders) {
    $ACL = Get-Acl $F.Path

    # Set the first parameter to $true to disable inheritance
    # Set the second parameter to $false if you don't want to retain a copy the permissions to this folder.
    # Set the second parameter to $true if you want to retain a copy of the inherited permissions.
    $ACL.SetAccessRuleProtection($true, $true)

    # 'ReadData' grants List Folder / Read Data
    $List = New-object System.Security.AccessControl.FileSystemAccessRule($F.List,"ReadData","Allow")
    $ACL.SetAccessRule($List)

    # 'ReadAndExecute' grants Traverse Folder / Execute File
    # 'Read' only grants List Folder / Read Data
    $Read = New-object System.Security.AccessControl.FileSystemAccessRule($F.List,"ReadAndExecute","Allow")
    $ACL.SetAccessRule($Read)

    $ReadWrite = New-object System.Security.AccessControl.FileSystemAccessRule($F.ReadWrite,"Modify","Allow")
    $ACL.SetAccessRule($ReadWrite)

    $ACL | Set-Acl $F.Path
}
