Subject: SCADA computer HMI update

Hello,

I just wanted to give you an update on the SCADA computer at the WTP. Matt from industrial systems finished up a little bit ago and he pulled some error records off of the system. He also found a couple viruses on the computer and removed them. He installed some antivirus software on the computer. He said the antivirus should not conflict with the programming and if it does he can remove it. He wants us to let him know if we get anymore system crashes or errors over the next week or so, and if we do he said he will most likely proceed with replacing the computer. I just wanted to keep you in the loop on this and we will let him know if there are any more issues.
