REPORT.
An organism B. 98 belonging to the susceptible class, and which usually appears in waters after a
heavy shower, was isolated from the sample taken from the head works. Laying aside this accidental
contamination, the water both at headworks and distributary system is of very fair quality both chemically
and bacterially.
