KURNOOL.
WATER SAMPLES TAKEN—29TH SEPTEMBER 1912.
Remarks .—The Cuddapah-Kurnool canal was in high flood when samples were taken. The
supply is intermittent. There has been about 14 inches of rain since last
analysis. The sample from the first tap after service reservoir was not taken as
there was no flow of water through the tap owing to the low level of water in the
service reservoir.
