POTABLE WATER SAMPLING PROCEDURE

Keep the sample bottle sealed and closed until it is to be filled.
The pill in the bottle is to keep the water stable until it is delivered to the lab.
The sample may be collected from any indoor faucet. (if tap cleanliness is questionable, apply a weak solution (sodium hydro chlorite-Bleach and Water- 1 tablespoon of bleach per litre of water) to the faucet.
Prior to sampling, remove any aerator or screen mechanisms.
Open the tap modestly to establish a strong but constant flow to allow clearing of the service line. We recommend to allow the water to run for a minimum of 5-10 minutes before filling the sample bottle. (water flow should be appropriate to allow filling the bottle without any splashing)
Remove the cap; DO NOT touch or otherwise contaminate the inner surface of the cap and/or neck of the sample bottle.
Without sensing, fill the sample bottle to thee 100ml mark (fine line) inscribed on the side of the bottle. Do not overfill, leaving ample air space in the bottle, to facilitate additional laboratory procedures.
Tighten the cap on the sample bottle immediately after sample collection.

NOTES:

Return water sample the DCS Controls promptly after collection to avoid unpredictable changes. If samples cannot be processed within 3 hours after collection, use an ice cooler for storage during transport to the laboratory.
If it is known that the test results will be used in a legal action: do employ a special messenger to deliver the samples to the laboratory within 6 hours and maintain a chain of custody.
Do hold the temperature of all potable water samples below 10 degrees during a maximum transport time of 6 hours. - Even with refrigeration do not exceed 24 hours elapsed time (maximum) between sample collection and examination.
Do not sample from a leaking tap that allows water to flow over the outside of the tap.

Even a weak bleach solution is a strong disinfectant. Unless the solution is well eluted, test results may be compromised. An alternate method of metal tap disinfection involves “flaming” the tap with a lighter. It must be recognized that even a brief “flaming” of the fixture may result in damage to the finish.

WELL SHOCK CHLORINATION PROCEDURE

The following well water chlorinating procedure should only be considered as a temporary solution for the mitigation of the presence of microbiological growth until the source of the contamination can be identified. It is suggested that prior to commencing the procedure:

Proceed with the following instructions:

Pour the bleach (chlorine) solution into the well.
Attach a garden hose to an outside faucet and place the other end into the well.
Turn on the outside faucet and allow the water to circulate for approximately 45 minutes to one hour.
After outside circulation, open each faucet in the house (including hot and cold-water faucets, dishwasher, toilets, baths, showers, clothes washer) one at a time until the smell of chlorine is apparent, then shut them off quickly. Do not run excess water into your drain as chlorinated water going into your septic system may affect the biological activity.
Do not operate your water system for a minimum of eight hours – 24 hours is recommended.
After the holding time period has passed, place the end of the garden hose at a location where the chlorinated water will not damage any desired vegetation. Open the garden hose faucet and allow the water to flow until a strong chlorine odour is no longer apparent (generally two to three hours). If you have a low yield well, caution may have to be exercised as this extended flushing may pump the well dry.

NOTE: During the flushing procedure, the water may have the colour of tea, but will improve after a short period of time. As a result, screens in faucets and the cold-water inlet of the washing machine may become plugged with sediment.

Normal water usage may be resumed. It may be two to three days before the entire chlorine odour and taste is gone. A follow-up sample of your well water should be collected and analyzed before consumption begins. The follow-up sample should be collected and tested approximately one week after the completion of the above procedure.
