POLLUTION OF RIVER.
There is a pipe from a surface water drain discharging
into the Roding at the bottom of Roden Street, and a complaint
was received from the Thames Conservancy that this
was discharging sewage matter. A sample of the effluent
was accordingly taken and sent up for analysis, with the
following result :—
"Report on a sample of water from the Ilford U.D.
Council, taken on November 4th from a surface water
drain discharging into the River Roding."
The water was examined, both chemically and
bacteriologically, and both results indicate that it
contains matter of sewage or manurial origin.
It corresponds closely to a good sewage effluent.
There is a drain discharging into this main surface water
drain in Roden Street, and as there is always a fair amount
of water discharging through this, a sample was taken and sent
up, with the following result:—
"Report on a sample of water from Ilford. Taken
from drain at back of houses in Roden Street on
November 22nd."
This is a very curious water, containing a large
quantity of saline matter in solution, but very little
organic matter, and the merest trace of sewage or
manurial matter.
It may contain an effluent from some works or
it may merely be surface water from roads and
yards.
There does not appear to be anything in this
particular sample which would deleteriously affect
the river.
