Hi,
I am interested to find out how people approach soil gas risk assessments
where flow is recorded as 0. It is impossible to calculate GSV when maximum
flow rate is zero. However, I would be uncomfortable with classifying a site
with say 15% CO2 as CS1. I hear a number of professionals simply insert
0.1l/hr as a conservative flow rate (instead of zero) so that GSV can be
calculated?
i would welcome your opinions.
Regards
Tilly
