Analyst Duncan Reports
Upon Six Wells Out

l
can' Food Commissioner and Analyst,
on the water supply of that portion Of
the Moiliili district along Beretania
street from the rice field, Eva of the
Baseball grounds, to the Moilili
church. the residents dependent on
such supply are in some danger. The.
report is in part as follows:
The water supply Is obtained MAIN
ly from wells, few residents. how
ever, obtaining their water from ar.
tesian wells of the rice fields.
The land is mainly coral formation.

the wells are in any way protected
from surface seepage, and from the
well known porous nature of coral con-
tamination with surface water may

waters main reliance is placed on the
nitrogen Items; l. e., free and albumi-
mold ammonia, and nitrogen as nitrates.
and nitrites. Well waters of good
quality should not contain nitrites, or
only as a trace; where it rises to a.
measurable quantity 1t shows that con-
tamination has probably taken place.
During the winter season, at the
request of the city sanitary officer, a.
number OF wells Of this district were
examined and the analyses touched
upon in my monthly reports at that
time. For the purpose Of comparing
The winter and summer season water,
l embrace these analyses in this re-
port.
No. 1. Water from Japanese
lodging house. The lot is about 60 feet
wide and contains lodgings on three
sides. The place contains two wells,
one near Beretania street. the other
6O feet makai of the first; the cess
pool is located between the two wells.
These wells differ markedly in the va
rious analytical items and, from the
high figures obtained for nitrites and
nitrates, are polluted The same
waters examined November 10, 1908,
show much higher content of un-
oxidized heterogeneous matter, the con-
Eliminating matter at that time being
in fresh state.'
Mr.. Duncan gives the winter and
summer analyses of No. /, well near
Beretania street, to which the forego-
ing general remarks apply, and then
comments on the analyses of No 2,
well sixty feet makai of the first, thus:
mo. 2. Nieka-Japanese lodging
house, Eva of baseball grounds. Depth
of well, eight and one-half feet This,
well is said to be not used for drinking,
but only for washing. The high figure
for nitrates and trace for nitrites casts
suspicion on this water"
Comments on the analyses given for
the remaining wells Investigated are.
as follows:
mo. 3. Kauai-well about two hun
dred feet makai of Beretania street
and about seventy-five feet makai of
pond where washing is done. Depth of
well, seven and one-half feet. This is
one of the worst waters examined.
The we'll is almost in direct line with
the pond and, no doubt receives drain
age from it.
No. 4. acknowledgements lodging
house, Waikiki of baseball grounds.
Depth of well, ten feet. This water Is
high in nitrates and contains a meas
urable quantity of nitrites. 1t is pol
luted.
mo. s. All Poy-well supplying poi
shop. Depth of we'll, six and one-half
feet. This is the worst water of the
list. At the time samples We're taken
1t was uncovered. which Is probably its
normal condition. Across the street
there are a number OF lodging houses
and the drainage from these cesspools
probably finds its way into this well.
For the purpose of comparison, an
analysis of this water, made November
10, 1903. is given, As remarked In No.
