Based on Analytical Study.
Dr.. Parran's report was based on
an analytical study of the Gobel
Co. plans for its Benning packing
plant and stock-yard operations. 1t
went more fully into details of sewage
and pollution than a previous report
submitted by a Public Health Service
sanitary engineer at recent hearings
on the King anti-nuisance bill.
It brought up also the question OF
study Of Potomac River water and
In this connection the report said:
If this (GobeD plant should be con-
structed and operated at or near Ca
pacity, it will be necessary that study
b made OF the Potomac River in the
vicinity OF the sewer outfall to deter
h1ine the exact effect Of the additional
pollution, particularly during low wa
ter periods. and to provide the neces-
sary data upon which extension to the
present sewage disposal plant may be
based"
Dr.. Parran also warned: care also
would have to be exercised in this
area to prevent the production of pest
mosquitoes during the Summer
months" He referred to an evident

In connection with the independent
Union Stockyards, which adjoin the
Gobel site
The simple reasoning on which the
surgeon generals report indicates the
possible need to extend the sewage
system Is based on the estimated
3,l52 animal capa city OF the plant per
day, equivalent to the population OF
100000. The Districts primary sew
age trea tment plant was designed to
care for approximately 650,000 people.
the estimated population in the next
Is years.
Population Now 550,000.
The present population Is approx
mately 550.0O0. Therefore" the re-
port said, the addition OF sewage to
be expected from 100000 people would
cause some dificulties in the proper
operation Of the existing sewage treat
ment plant, and q reduction in its
efficiency"
THE existing sewage treatment
plant is designed as primary treat
mert plant only" DR.. Parran con-
tnued, "in which the settleable solids
OF the sewage are removed. Such a
plant will remove approximately 50
per cent OF suspended organic matter
and will give a 331s purification to
the sewage. Packing house waste IS

lend itself read dily to the usual methods
Of sewage treatment"
Such waste contains a great vol
ume Of putrescible organic matter both
IN suspension and in solution, the
report stated, and volume for volume
It greatly exceeds that in domestic
sewage. The waste from a complete
