    I believe you can, while you don't find a utility that may help you delete
    the ADS, empty the ADS of its data.
    Below, there's an example of such action. In this example you'll find an
    open source utility named ScanADS available at
    http://www.kodeit.org/products/scanads/default.htm that scans ADS in local
    and remote machines.

    ^Z = CTRL + Z
    ^C = CTRL + C

    ------------------------------------------------------------------
    C:\>mkdir c:\zzz

    C:\>mkdir c:\zzz\xxx

    C:\>more > c:\zzz\xxx:aaa
    a
    b
    c
    ^Z

    C:\>ScanADS.exe -v -s c:\zzz\

    Verbose: yes
    Recursive: yes
    Get Data: no
    Server: localhost
    Path: c:\zzz\

    (1 ADS): c:\zzz\xxx
            (11 bytes) :aaa

    C:\>more > c:\zzz\xxx:aaa
    ^C

    C:\>ScanADS.exe -v -s c:\zzz\
