I hope this message finds you well.
As always, many thanks for your huge help last week with our Audit. We finished the past Wednesday and we have great news!! We got approval from the Authority.
Now our system for Water Quality Monitoring is approved by the ............ Authority in Colombia. This will be of great help on our future projects! This great result would not have been possible if not for your kind and prompt help with the documentation and support.
Many many thanks!
