Good day! I would like to request the following document for our Architectural thesis about buidling a passenger ferry along the tullahan river:

- current water classification of the Tullahan River
- pollution level of the Tullahan river
- presence of toxic substance in the river
- safety advisoty (if it is dafe for boats and ferry

It would also be nice if we could know where to get the information or if we could get it from here:

- current and on going rehabilitation of the river
- status of river dredging 
- initiatives in cleaning the river

Thank you for your help!
