WATER SAMPLING GUIDE
In accordance with the regulations in order to ensure that the water intended for human consumption is in compliance with technical and hygienic conditions, the quality standards of the waters are provided, the consumer population is informed about the negative effects that may occur due to the quality of the water, and recommendations are made to ensure the protection of human health and the necessary precautions are taken. Water samples are taken at regular intervals.
Control trace; It is carried out in order to determine whether the water complies with the required parameters, to provide regular information about the organoleptic and microbiological quality of the water, as well as, in the case of drinking water treatment, whether this treatment is effective.
WATER SAMPLING AND ACCEPTANCE CRITERIA
1. Chemical and microbiological sample containers (bottles) must be obtained from the laboratory. At the end of sampling, labeling should be done by the person taking the sample in accordance with the following items.
2. Microbiological water sampling technique should be as follows;
- Taking water samples from network fountains: First, any apparatus on the fountain is removed. The faucet surround of the fountain is wiped with alcohol and burned. Water is poured vigorously from the fountain for at least 30 seconds. Depending on whether the water is chlorinated or non-chlorinated, the selected sample bottle is held by the cotton tip, and the bottle is opened without touching the cork, and the bottle mouth is held from the bottom and passed through the flame. The bottle is filled and closed carefully without touching the cork. It is stored in a cold chain environment at 5 (± 3)° C and delivered to the laboratory within 12 hours.
- Taking a water sample from the source: Thoroughly cleaned, boiled and burned iron or glass pipe is immersed in the source or 1 meter around the source to prevent contamination of animal wastes that may be found in the open environment. Water is poured from the pipe overnight and a sample is taken in accordance with the principles in part a
- Taking a water sample from the tank (cistern): After thoroughly washing the hands, the hand and the sample bottle are wiped with alcohol cotton and a string dipped in alcohol is tied around the neck of the bottle. The mouth of the bottle is burned. The bottle is filled by immersing in the place where the sample will be taken. The sterilized cork is opened on the flame and closed without touching.
- Sampling from the well: Sampling from wells with Tulumba is done in accordance with the principles in item a, and sampling from wells without a pump is done in accordance with the principles in item c. For germ analysis in packaged water (22°C and 37°C): The sample is transported to the laboratory within 12 hours after packaging and stored at 4 ( ± 1 ) °C.
3. In the microbiological water analysis of the sample, if the sample is chlorinated, 118 mg/L should be taken into sample bottles with sodium thio sulfate.
4. The total and free chlorine content of the sample should be measured using diethyl-para-phenylene diamine.
5. For microbiological analysis of drinking and utility water 500 ml, for chemical analysis of drinking and spring water 1000 ml water samples should be brought in bottles provided by the laboratory or in sterile original packaging.
6. The technique of taking water samples for chemical analysis should be as follows;
- Water sample should be brought to the laboratory as 1000 ml in a dark glass or disposable bottle.
- Sample acceptance form must be filled in by the person taking the sample in accordance with the principles of Article 1.
- Well, fountain, spring, etc. Taking chemical water samples from places: With the help of a pump or tap, the water is drained until you are sure that the bottom waters feeding these areas come, the system used for draining the water must be chemically clean. Samples should be taken after placing a clean pipe in the place where the water comes out in small flow springs and in one of the wells in large flow and ponded springs.
SAMPLING FROM FAUCET OR PUMP OUTLET
Serilize the faucet for one minute by lighting it with a lighter, a gas stove, or a cotton pad impregnated with alcohol and lit. Open the faucet carefully and wait 3-5 minutes for the water to flow at an average rate. Do not adjust the faucet again after setting it once. tap 3 Take a bottle and carefully open the cap or unscrew the stopper. Holding the cap and protective cap downwards (to prevent ingress of dust that could contaminate the sample), immediately hold the bottle under running water and fill. A small air-filled volume should be left in the bottle to facilitate shaking prior to analysis. Insert the stopper or close the cap and thread the brown paper protective cap in place.
SAMPLING FROM WELL AND SIMILAR PLACES
Spiral grip, Half grip, Stone Using a piece of string, tie a clean weight to the bottle to be sampled. Take a clean 20-foot-long string, wrapped around a stick, and tie it to the bottle. Lower the weighted bottle into the well by slowly unwinding the rope. Do not let the bottle touch the well walls. Submerge the bottle completely in the water and lower it well below the surface without hitting the bottom of the well or removing any sediment. After you are satisfied that the bottle is full, rewind the rope to the stick and pull the bottle up. If the bottle is full, pour some to create an air-filled volume. Close the stopper or cap of the bottle as previously described.
