Water footprint Assessment AWARE method

Hello OpenLCA Team

As I understand ecoinvent 3.2 datasets are now balanced. From the inventory results I get some water flows represented in Kg, and others in m3.
I am attaching image of and excel sheet I used to understand LCI results from coal power generation model.
Inventory analysis in excel to transform kg units into m3

In excel sheet, If you convert from kg into m3 then yes all process are balance.

I am creating a new Impact assessment method based on the AWARE, water scarcity characterisation factors from the WULCA project. I have downloaded KMZ and excel layer and have the characterisation factors for annual and monthly time periods. These are expressed in m3 regional/m3 world

Question 1
Within openLCA impact assessment method section, I assume I need to convert to m3 those flows expressed in kg? right?

Question 2
I have transformed KMZ layer to shape file using Quantum GIS, however when I import into openLCA there are only three parameters with negative values. Therefore, I assume this layer is not ready to be used for openLCA. However in Google Earth pro, the layer does contain the characterisation factors on a monthly and annual time periods, for all watersheds in the globe, probably because some of the fields of kmz layer have html references to the original source. Is there a way to work on the layer to adapt it to OpenLCA and use annual and monthly regional characterisation factors?

Thanks, and best regards to all.
