The first well came out of water smoothly. Whether it was the Chen family or the nearby people watching the fun, everyone was very happy, but there was still something wrong in the middle.

The problem lies in the water extracted. Technician Wang from the Agricultural Bureau had an argument with Lao Song, a well drilling manufacturer.

Wang Dachun is a professional. He said that the well water cannot be drunk directly and insisted on taking samples first for inspection, otherwise it would be unsafe. Lao Song from the well drilling machine factory was much simpler. He took a basin of water, rubbed it with a piece of soap, and then made a promise that the water was fine. The two of them fought over, and no one could convince anyone.

The group of people watching the fun were stunned. No one expected that the only two wise men in the well-driving team would be in trouble. Wang Dachun was a college student, so professional knowledge was definitely fine. Lao Song graduated from junior high school and was a self-taught local expert. Now the two are having a dispute, and no one outsider can interfere.

Chen Qiaoshan studied high school chemistry and after reading it for a while, he probably understood that Lao Song used a local method to measure the softness and hardness of water.

Soap contains sodium stearate and sodium palliate. When it is encountered, it contains a large amount of calcium and magnesium ions, a chemical reaction will occur to generate precipitates that are insoluble in water. In this way, there will be much less foam in the soapy water, and there may be insoluble substances in the water. This method can detect hard water.

Wang Dachun is a professional, and he can understand Lao Song's method, but he cannot accept this method. The local method is too rough, and who knows there is something else inside.

Qianwang Village is located in a remote location and there are no industrial enterprises around, which eliminates the absence of heavy metal pollution in the groundwater. What Wang Dachun is worried about should be other physical and chemical indicators, such as pH value, solubility, and ion concentration.

Chen Qiaoshan knew that there should be no big problem with the water. The Chen family had used it for many years, and it was not the Chen family who drank groundwater, so there had never been any problems.

However, he still agreed with Wang Dachun's opinion. This is a water source for the family to drink, which is related to the personal safety of the six people in the Chen family. Now that the conditions are available, it is best to test it.

It’s not that he was suspicious, but he was afraid of it in his previous life, melamine, sultan red, gutter oil, Chen Qiaoshan knew better than anyone else how difficult it is to live. He had to be responsible for his family and also seek peace of mind.

The debate didn't last long, and no one took it seriously around the neighbors watching the fun. How many years have you eaten this water? What's the problem?

The first well took no time, and the newly formed well drilling team immediately changed the scene. The second well was opened at Er Bo's house and the water was successfully released in the afternoon, but the water was very turbid.

Lao Song provided two solutions: one was to pump water and drain all the mud and sand inside, and the other was to let it sit for a few days. If it still didn't work, it would need to be filtered. These were what Chen Dad later told Chen Qiaoshan that he did not go to the scene.

Two wells were dug on the first day, and the process was very fast. Lao Song said that it was mainly because the groundwater layer was shallow and he did not touch the stone layer. The whole well digging process was very smooth, but there were many problems. Fortunately, there were two major professionals who were proficient in law protection, so there were no major problems.

That night, the Chen family set up a wine to celebrate. There were no outsiders at the table, so the three people from the well digging team, including Wang Dachun and Lao Song, and Chen Weiguo and Chen Qiaoshan and his son, the Chen family did not serve.

Tao Xiuying never stings when hospitalizing guests, the dishes were very rich and everyone enjoyed their meals.

There was no big drink at the table. Except for Wang Dachun and Chen Qiaoshan, the others here are already middle-aged. Everyone is eating and talking, and they are talking about digging wells.

Lao Song is a straightforward person and tells all the tips he knows, especially introducing the maintenance and maintenance of the well drilling machine. He has no hidden personal information at all. He even talks about some minor problems in the machine, and people benefit a lot from it.

To be honest, we cannot underestimate these local experts. Although they have not received higher education, their knowledge is achieved through practical work, which is more thorough than in books. After some words, even Wang Dachun has benefited a lot.

After a long meal, the guests and guests were having fun. When the banquet was over, Chen Qiaoshan quietly pulled Wang Dachun and asked him to help test the water quality of the Chen family. He did not refuse and agreed immediately. The Agricultural Bureau had a laboratory, so he still had this face.

...

It was late at night and the Chen family was still sitting in the yard to enjoy the cool air.

"Dragon, how are your feet?"

Chen Qiaoshan is immune to the symmetrical problem. He cannot change Chen's mother, so he can only change himself.

"Mom, it's nothing. I'll try it in a few days!"

Chen's mother was worried and told: "Forget it, don't show off and stay at home honestly!"

Chen Qiaoshan agreed, it was nothing wrong to be safe, and the topic of chatting turned to digging a well.

The drilling machine bought by Chen's family can have a maximum aperture of 200mm. Lao Song recommends drilling a hole of 160 so that the machine can maintain the best performance and save costs. The drill rod and drill bit are consumables, and the replacement cost will not be less.

The groundwater is still quite abundant now, especially in rural areas. The basic depth is 30 to 40 meters. The water volume is enough. Lao Song knows the market for drilling wells. The recommended charging standard is 35 per meter. The cost of a well is about 1,500. There are also submersible submersible pumps and water pipes in deep wells, which are all covered by about 2,500 yuan.

These days, the average annual income of farmers is only this amount, and this expenditure is quite large. Fortunately, irrigation is not a household and one well, and it can be used by three or four households. Moreover, with deep wells, there is no need to worry about drought, and the market problem should not be big.

After careful calculation, deducting the cost of artificial materials, the net profit per well was about 1,000 yuan, which was more than Chen Weiguo's monthly salary. The Chen family was shocked and never thought that money would be so easy to make.

Chen's mother couldn't help but say, "Or let's take a little cheaper, this is too scary!"

Chen Qiaoshan couldn't stand it anymore. Chen's mother's idea was very weird. How could she be the boss's wife like this!

"Mom, judging by what you said, the accounts cannot be calculated like this. You haven't calculated the depreciation of the machine, are also the cost of post-maintenance. Drill bits and drill rods are consumables and are easily damaged. If you break a little, a well will be in vain!"

Chen's mother was embarrassed. He knew that the second child was talking about the truth, but he was a little angry when his son refuted it like this, and muttered again: "I just said that."

Chen Qiaoshan knew that Chen's mother was worried because she was afraid that the people around her would gossip, so she explained: "Mom, Master Song has said that other well-driving teams have collected 40 to 51 meters, so we are already cheap enough!" Chen's mother gave up.

The well-driving team started to undertake business. First, they were around the village. In just six days, eight wells were dug. Other villages had already started to contact each other after hearing the news, but the work in the village had not been completed and they could not get out in a short period of time.

The Chen family finally got on track according to Chen Qiaoshan's plan, and there were not many things he had to worry about.

Chen Wan has finished the high school entrance examination. A few days ago, teachers from various high schools took turns to work at the Chen family, and the promises they gave were better than each other. However, her application was still filled in for one high. Of course, the treatment given to her by the first high is not bad, and she is even better than Chen Xi. She has a monthly subsidy of 300 yuan, so basically she doesn’t have to pay at home. Of course, the Chen family is not short of this amount of money now.

The changes in the Chen family are obvious to all. The people in the village are a little dazzled. In just over a month, the Chen family has undergone earth-shaking changes. People nearby say everything, but most of the reasons are on Chen Qiaoshan, and they all pulled Chen's mother and said that she had a good son. Over time, Chen's mother became more and more confident in front of others.

Chen Qiaoshan was very satisfied with the change of the Chen family. The well-driving team was on the right track. Although Lao Song had left, Wang Dachun was still there. The well-driving team had almost learned it. If you have any questions, you can contact us at any time and there was nothing to worry about.

Chen Qiaoshan was bored at home, so he wanted to tutor the third and fourth brothers in English. He was very self-aware and had some confidence in English. Fortunately, his grades were enough to fool people, so Chen Xi and Chen Wan followed them obediently, and the results were pretty good.

Learning depends on accumulation, and it will not have much effect overnight. Chen Qiaoshan thought about whether to buy mp3 for the two of them. He would learn English as soon as he had nothing to do, but nowadays, the teaching materials and aids are equipped with tapes and CDs, so he gave up. If he really bought the mp3, he would listen to the songs, which would definitely make Tao Xiuying complain.

Xiaowu has worked very hard recently, and the final exam in elementary school was a little later. The little girl has worked very hard recently, and even Chen's mother was surprised. She said that she had never seen her so attentively since she was a child.
