How did the information get there in the first place?

I am getting this file from from client where address has duplicates value.

Then you need to go back to the client and explain that they have a problem in their data.

Yes you are correct Richard but there should be a solution for this problem.
After solving this i can raise this issue to them.

Do it in your presentation language:
Read all rows - check each row, and see if it's a duplicate:
private bool IsDoubled(string s)
    int half = s.Length / 2;
    if (s.Length % 2 != 0)
    for (int i = 0, j = half; j < s.Length; i++, j++)
        if (s[i] != s[j]) return false;
    return true;
If it is, use Substring to halve it, and UPDATE the DB Row.
