The underground wells are regarded the most important sources of water in the Kingdom of Saudi Arabia, while the Kingdom digs these wells. It has been proven that there are many wells in some regions such as Al-Harrah region in order to face the water crisis. This research aims at studying the effect of underground wells in Al-Harrah region on the decrease of Oxygen saturation rate in water the deeper the wells are. This research is divided into two parts: the theoretical and the practical part through the usage of the experimental method for its adaptability to the nature of the current study. The study has reached to important results among which: When the well becomes deeper, the rate of Oxygen saturation in the water decreases. Some of the study's recommendations are: 1- Doing a project research that aims at studying the radiation rates in the underground water in the said regions. 2- Warning individuals of random digging of wells and making them depend on specialized companies in this field. Hypotheses: There is a relationship between the deep underground wells in Al-Harrah region and the decreased rate of the Oxygen saturation in its water. Procedures: Samples of wells with different depths in Al-Harrah region was drawn to measure the Oxygen saturation therein. Main Results: After making the measurements, the decrease of the oxygen saturation with the depth of the well was has been observed. Results: 1- There is a negative relationship between the increase of the well depth and the rate of the Oxygen saturation in the water. Research Question: What is the relation between the depth of the deep underground wells and the rate of the oxygen saturation?

1- How long have you taken to study the subject?

2- How many underground wells are used in research?

1- How long have you taken to study the subject ?
- I have taken four months in order to collect the samples and study them .

2- How many underground wells are used in research?
- Due to the difficulty of reaching ALhara region which is located far away from Tabuk city ,
we have chosen five underground wells for our research study , And we tried our best to take sample as much as we could .
And last week we took a sample from underground well of 1200 km depth . Also,we recorded the percentage of oxygen melt which was 3 mg/L .

Water is very important--so good job choosing a topic.
Very nice discussion of water resources!

Hi Aisha. You have done a great project on DO and the depth of the well. I have some questions to ask.
(1) how did you measure the depth of the wells in your study? It seems to me that you got it from interviewing with the well owners. If yes, how do you know for sure that was the correct depth.
(2) for the negative correlation between the DO and the depth of wells, it might be a trend but this needs some statistical test. If you were going to test this, what kind of statistical test would you plan to use?

- We have cooperated with well drilling company . It has specialized services that helped us to check the depth of the well .

- I would choose the descriptive statistical analysis method .

Hi Fatmah,
For the statistical analysis, you could not use the descriptive statistics to analyse the trend. It would be better to use some correlation or regression on this. :-) For your future works. Keep doing this great work.

You gave your dissolved oxygen in the units of ml/L. How do you compare it with WHO recommendations that are given in mg/L

You gave your dissolved oxygen in the units of ml/L. How do you compare it with WHO recommendations that are given in mg/L?

- We have mentioned in our research that the melting percentage of oxygen is between 5 to 8 mg/L according to the WHO standards of drinking Water .
However , we found that its percentage is between 3 to 4 mg/ L which is less than the normal average of drinking Water .
