Are you using a local DNS server?
You have three entries here...

... but only one entry here.
Anyway, if you want to add 'nameserver' entries you have to add them as
'dns-nameserver' in /etc/network/interfaces.
If you want to remove some the other ones you have to trace which
package is adding them (via resolvconf). Could be a dhcp client, DNS
server, another network manager (e.g wicd), etc.
Hope this helps,
Andrei
