Thanks!

What is the effective circumference of each test and how can we gain more
information?

Thanks for you attention

The "Amoozemeter" is a compact constant head permeameter that is considered
the state of the art in North Carolina. It has a attachment that will allow
the
user to make evaluations to thirteen feet below surface before a pit is
required.

Hi All!

We are seeking your input and assistance concerning estimating effective
permeability
of fill materials.

To make a long "story" short(er) we are seeking an established protocol
to estimate effective permeability over a wider area than typical for a
standard
falling perk. procedure - perhaps a trench version of the falling head
procedure?

We thought you might be familiar with such an already developed "trench "
procedure - or you might have developed one for use with characterization of
fill
materials.

The situation is that active roots extend though the fill & have developed
weak
structure within the fill - it is unsure if the effective permeability is
greater
than 0.2 - or significantly less. Which would make quite a difference as to
required
acreage for spray irrigation of pretreated effluent.

What we have to do is have pits excavated 4 feet deep then install and run
"perch
test" procedures within the excavations - below the 5 foot "soil"
depths.

We feel that 2 or 3 trench tests would be more practical and representative
than
8 to 12 individual perk holes - not to mention
effort..

Thanking you in advance.
