SUGGESTED PROCEDURE FOR OBTAINING

STERILE WATER SAMPLES:

Prior to taking the water sample, be sure to have on hand an

adequate supply of sterile bottles (as shown in Fig 1). These

sterile bottles should be obtained from a reputable laboratory

and should have been autoclaved and contained within a

plastic outer wrapping.

1. Prior to taking the sample, it is imperative that the sample

valve, faucets, etc. be opened at full force for a complete three

and a half minutes.

2. After the valve has been fully opened for three and one

half minutes, reduce the flow to a reasonable stream of

water. Flow to drain an additional three minutes.

3. Open the sterile bottle or sterile container being used.

Holding the cap in a down position, the operator should then

hold his breath while taking the sample so as to avoid oral

contamination of the sample. The operator must not allow his

finger to touch the inside of the cap or the neck of the bottle.

4. After the sample has been taken, the cap should be tightly

placed on the sample container.

5. The sample container should be placed in a plastic wrapping,

kept cool, and should be taken to the laboratory for testing as

soon as possible following the above procedure.

We recommend duplicate samples be taken at each test station

during each specific test so as to avoid loss of sample through

laboratory error and to insure reasonable validity through

comparison.

Check with your local laboratory to assure proper sampling

and submittal procedure.
