Hi Chris,
Any reputable geotechnical laboratory could make this determination for you.
They will need to determine bulk density, moisture content and specific gravity for the various soil fractions present in your soil to determine the void ratio and hence porosity. You are also likely to require a particle size analysis and/or sedimentation test to assess the overall variability of the soil, since it may not have a unique porosity, but moreover it will vary.
Unfortunately I do not have current laboratory testing rates but these are NOT expensive tests. It would be inappropriate of me to recommend a specific laboratory for you to approach, but there are many.
Good Luck.
Regards,
Paul

Subject: Effective Porosity?
Morning Everyone.
Does anyone have any experience of assessing Effective Porosity? I
presume you may need a U100 to be tested - but cant find any further
information on it.
Is there a standard lab test that can provide this? If so do you have any
idea of a approximate cost?
Thanks!
Chris
