• KAELEKU AGRICULTURAL SUBDIVISION: The Improbability
of Basal Groundwater Pollution from Cesspools
A question has been raised about the possible short-
circuiting of cesspool effluent from the Kaeleku Agricultural
Subdivision to the basal groundwater body some 400 feet below
the land surface. In this instance, short-circuiting presumably
means the direct, unimpeded vertical transfer of a water
particle from a cesspool to the water table. There is virtually
no possibility that such a phenomenon could occur; 400 feet of
complicated geological conditions between the surface and the
water table guarantees that any particle of water will follow an
extremely tortuous path in its downward movement. The pathway
will be through weathered and fresh Hana series lava flows, then
weathered and fresh Kula series lava flows, then finally through
a weathered zone before reaching the water table in fresh
Honomanu series flows near sea level.
The drainage of vertical infiltration through weathered and
fresh basalt flows of thickness in excess of 50 feet rarely, and
probably never-except in extraordinary situations where large
caverns occur-retain either bacterial or viral contaminants with
which it was originally charged. Only inorganic non-reactive
chemical species, such as nitrate, will percolate to the water
table, but the quantity of these constituents will be so small
in relation to the enormous flux of groundwater that they will
be diluted to trace amounts to a few mg/l.
Elsewhere in Hawaii, cesspools and septic tanks have been
constructed near and above domestic water sources with no
experience of organic contaminants ever reaching the water table.
An excellent example was the cesspooled area on the heights
lying above the Honolulu Board of Water Supply water development
shaft on Waialae Avenue; water from the shaft has never shown
evidence of contamination, although several mg/l nitrate may
have been contributed to the water's composition over the long
term. In the Pearl Harbor region, a vast infiltration scheme
has been carried out since the turn of the century in the form
of irrigation; no contamination by herbicides or pesticides of
the groundwater several hundred feet below the surface has been
experienced, although an increase of nitrate to a steady state
concentration of from 5 to 10 mg/l, far below acceptable
standards, has taken place.
Recent experiments by the Water Resources Research Center
of the Univeristy of Hawaii over a several year period in which
effluent containing viruses and organics from the Mililani
treatment plant was used to irrigate sugar cane on fields lying
directly above the basal water have shown that neither contaminant
is able to drain beyond about 10 feet of soil and weathered rock.
In the Xaeleku region, the complex geology includes not only
surface residuum but subsurface unconformities of weathered
rock and probably soil. Given the nature of the overburden
lying between the surface, where the cesspools are to be driven,
, -!
• and the basal water table, the probability of organic or viral
contamination of the groundwater is remote, if not impossible.
Any chemical species, in particular nitrate, which would penetrate
to the aquifer from the agricultural subdivision would suffer
such great dilution that its occurence would be nearly undetectable.

Re: Kae1eku Agricultural Subdivision
As I mentioned to you, Mr. Maurice Kruth, Chief Engineer, Maui Environmental Health Division for the Department of Health, raised the question concerning the possibility of a short circuit between cesspool and the proposec well.
We would appreciate a statement from you regarding this matter.
Enclosed are copies of your previous correspondence to us which you requested.
Please bill us for your services.

The specificatiobs for the Kaeleku Well for Hana Ranch appear to be adequate, but I believe pumping during testing should be restricted to 300 gpm and less. Based on the data for the State well nearby, the aquifer in the region is extraordinarily permeable and therefore the head is quite low even at great distances fro~ the coast. A highly permeable aquifer suffers little drawdown during pumping, but if there is no confining layer to retard discharge to the sea heads cannot build up very high. As a result, the lens will be thin.
Fortunately in the Hana region a very large ~low of groundwater passes through the aquifer and therefore the disadvantages of low head are alunterbalanced by the large flux. Nevertheless, a thin lens always requires great care in development. Depth of the well below sea level is especially important, as is pump capacity. Depth to -30 feet is allowable, whereas depth to -40 Or-SO feet might be catastrophic. A tight control must be practiced with respect to depth. Nor can pump capacity be large. The maximum allowable size will be determined from the pump test, but it is not likely to be more than several hundred gpm.
I would prefer that the step drawdown test be conducted at 50-100-200-300 gpm, and that even cleaning of the well should be done at no more than 300 gpm. From your original report, you will not need a very large pump in any event.
We can discuss this well in more detail when I return home in a-few weeks.
Sincerely,

SubnLittea herewith for your approval is a set of plans and specs for a well that Hana Ranch ia planning to drill for their above subdivision. The well will be part of a private water system. Capacity we are looking for is between 100-200 gpm. our consultant, Or. John Mink, has informed us that there should be no problem in getting this.
Hana Ranch would like to have t.lte plans out for bids in mid May. Therefore, an early reply and approval will be appreciated.

In fact, such a well would be capable of yle1dir~ co!':side:ra.bly more thar: the anticipated draft. The specific capacity of such a well would exce8c 100 gpr.l per foot of drawdown, which means that a rate of 100 gpm would re~ult in about-1 foot of drawdown. The quality of basal wate~ would be exceller.t, with chloride content substantially less than 100 DIG/l at controlled pumping.
The 10ea tior.. of the proposed well is a ppropria te for the pro jec t. p. well drilled to a maximum of -30 feet elevation would ea~ily provide the expected demand of the agricultural subdivision.
