Dear Dr. Allen:

At the request of your department I made an inspection today of the
swimming pool and of the filtration end purification equipment.

The water in the pool was turbid and gave off a considerable odor.
The odor can be described as a combination chlorine and mouldy odor.
The odor is caused, I believe, by the organic matter present in the
water. The increase in the number of persons using the pool has
placed a load on the filtration equipment that it cannot treat the
water properly under the present conditions of operation.

Most of the analyses have shown this water to be of satisfactory
bacteriological quality, but the physical quality of the water is

poor. In order to improve the physical quality I am listing some
suggestions below. Because of the limited capacity of the recirculating
pump and the filter it may be necessary to drain the pool once each

two or three weeks. The pump -now in use can recirculate ail of the
water once each twenty-four hours if kept in operation continuously.

The suggestions follow:

(1) Drain the pool end start again with clean water.

(2) Examine the filter to be sure that the ingredients are properly
graded and the required depth. The gravel should be 18" deep and the
sand 18" to 24" deep. The sand should have an effective size between
0.35 and 0.50 mm. and a uniformity coeffecient between 1.25 and 1.80.
