Help with change to a script.

Question

Where I work, we disable and add information to some AD fields when people leave the office for periods beyond a week.
We have a powershell script that is used to enable the accounts and for many of the fields we clear the information except for 1 field.
I am looking to add to the existing script to modify the description field. I want it to remove all data after the @ character, while keeping all the data before the @ character
Ex: Service Desk @ Away - Training.

You'll have to incorporate this into your script, but I'm glad to supply some code and logic for a single user, case scenario.
$User = 'username'
$Description = Get-ADUser -Identity $User -Properties Description | Select-Object -ExpandProperty Description
If ($Description -match '@') {
Set-ADUser -Identity $User -Description $Description.Split('@')[0]
To remove some of the procedural aspects you could return the description inside the If conditional. This can, however, make much it more difficult to read.
$User = 'username'
If ((Get-ADUser -Identity $User -Properties Description | Select-Object -ExpandProperty Description) -match '@') {
Set-ADUser -Identity $User -Description (Get-ADUser -Identity $User -Properties Description | Select-Object -ExpandProperty Description).Split('@')[0]
What we've accomplished in these examples is to split the description field at the @ sign and then grab the first element, or index [0]. This would be everything to the left of the @ sign. If there's only one @ sign, then element, or index [1] would be everything
to the right of the @ sign. In addition, element [-1] will always be the last, or right-most element. In the case of one @ sign, and therefore two elements, [-1] will be the same as [1].
