The first well came out of the water smoothly, whether it was the Chen family or the people gathered around to watch the excitement, everyone was very happy, but there was still something wrong in the middle.

The problem was the water pumped out, and Technician Wang of the Agricultural Bureau had a dispute with Lao Song, a well-drilling machine manufacturer.

Wang Dachun is from a professional class, he said that the well water can not be directly drunk, insisted on sampling and sending it for inspection first, otherwise it is not safe, the old Song of the well drilling machine factory is much simpler, took the basin of water and took a piece of soap and rubbed it, and then packed the ticket and said that the water is no problem, and the two of them are so barred, and no one can convince anyone.

The surrounding group of people who watched the excitement were stupid, no one thought that the only two people in the well drilling team who understood were on the bar, Wang Dachun is a college student, professional knowledge must be no problem, Lao Song graduated from junior high school, belongs to self-taught soil experts, and now the two have a dispute, and no one can intervene.

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

Soap contains sodium stearate and sodium palmitate, and when it encounters a large amount of calcium and magnesium ions in the water, a chemical reaction will occur to generate a precipitate that is insoluble in water, so that the foam of soapy water will be much less, and there may be insoluble substances in the water, this method can detect hard water.

Wang Dachun is from a professional class, he can understand Lao Song's method, but he can't accept this approach, the local method is too rough, who knows what else is in it.

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

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

However, he still agrees 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 members of the Chen family.

It's not that he is suspicious, he was scared in his previous life, melamine, Sudan dyes, gutter oil, Chen Qiaoshan knows better than anyone how difficult it is for people to live, he has to be responsible for his family, and at the same time ask for peace of mind.

This controversy didn't last long, and no one in the neighbors who gathered around to watch the excitement took it seriously, how many years has this water been eaten, what can be the problem?

The first well did not take long, the newly formed well drilling team was immediately transferred, and the second well was opened at the second uncle's house, and the water also came out smoothly in the afternoon, but the water was very muddy.

Lao Song provided two solutions, one is to pump water and pump out all the sediment inside, and the other is to let it stand for a few days, if it still doesn't work, you need to install a filter, these are what Chen's father later told Chen Qiaoshan, he didn't go to the scene.

Two wells were drilled on the first day, and the process was very fast, Lao Song said that the main reason was that the groundwater layer was shallow and did not touch the stone layer. The whole process of drilling the well was very smooth, but there were also many problems, but fortunately, there were two major professionals in the class and the people to protect the Fa, and there were no major problems.

That night, the Chen family set up wine to celebrate, there were no outsiders at the wine table, so the three members of the well drilling team, plus Wang Dachun and Lao Song, the Chen family Chen Weiguo and Chen Qiaoshan father and son, and the women did not serve the table.

Tao Xiuying is never stingy in hospitality, the dishes are very rich, and everyone eats very happily.

There was no big wine at the wine table, except for Wang Dachun and Chen Qiaoshan, the other people were already middle-aged, and everyone was eating and chatting, talking about digging wells.

Lao Song is a straightforward person, and he told all the know-how he knew, especially the maintenance and maintenance of the drilling machine, and he didn't hide it at all, and even talked about some small problems with the machine, and a table of people benefited a lot.

To tell the truth, we can't underestimate these soil experts, although they have no higher education, but their knowledge is made by hard work, which is more thorough than books, and even Wang Dachun has benefited a lot from some words.

After eating a meal for a long time, the guests and hosts were happy, and when the banquet was dismissed, Chen Qiaoshan quietly pulled Wang Dachun and asked him to help test the water quality of the Chen family, he didn't shirk it, and agreed to it, the Agricultural Bureau has a laboratory, and he still has this face.

……

In the dead of night, the Chen family was still sitting in the courtyard to enjoy the coolness.

"Dick, how are your feet?"

Chen Qiaoshan is already immune to the issue of salutation, he can't change Chen's mother, he can only change himself.

"Mom, it's okay, I'll try it in a few days!"

Chen's mother was not at ease, and instructed: "Forget it, don't be reckless, stay at home honestly!"

Chen Qiaoshan should go down, there is nothing wrong with being safe, and the topic of conversation has shifted to digging wells.

The hole diameter of the drilling rig bought by the Chen family can reach a maximum of 200mm, and Lao Song suggested that the hole diameter of 160 be drilled, so that the machine can maintain the best performance and save costs.

At present, the groundwater is still relatively abundant, especially in rural areas, the basic depth is 30 to 40 meters of water is enough, Lao Song knows the market for drilling wells, the recommended charging standard is 35 meters, the cost of a well is about 1500, and there are deep well submersible pumps and water pipes and other miscellaneous things, all inclusive down to almost 2,500 yuan.

Fortunately, irrigation is not one well per household, but can be used by three or four households, and there is no need to worry about drought if there are deep wells, and there should be no big problems in the market.

After careful calculation, after removing the cost of labor materials, the net profit of each well is about 1,000 yuan, which is more than Chen Weiguo's salary in a month, and the Chen family was stunned, never thought that the money would be so easy to make.

Chen's mother couldn't help but say, "Why don't we get cheaper, it's too scary!"

Chen Qiaoshan can't stand it anymore, Chen's mother has a very strange idea, how can she be a boss lady like this!

"Mom, look at what you said, the account can't be calculated like this, you haven't calculated the depreciation of the machine, right? There are also post-maintenance costs, drill bits and drill pipes are consumables, which are easily damaged, and if they are slightly broken, a well will be in vain!"

Chen's mother was sneering, and he also knew that what the second child said was right, but he was a little angry when his son refuted it like this, and muttered again: "That's what I said." ”

Chen Qiaoshan knew that Chen's mother was worried, because he was afraid that the people around him would gossip, and explained: "Mom, Master Song has said that other well drilling teams all charge forty to fifty-one meters, and we are cheap enough!"

The well-drilling team began to undertake the business, first around the village, in just six days, a total of eight wells were drilled, and other villages have begun to hear the news to contact, but the work in the village has not been completed, and it is impossible to get out in a short time.

The Chen family was finally on the right track according to Chen Qiaoshan's plan, and there were not many things for him to worry about.

Chen Wan has finished the high school entrance examination, and a few days ago, the teachers of various high schools took turns to work in the Chen family, and the promises given were better than the other, but her willingness was still a high one, of course, the treatment given to her by the first high school was not bad, it was stronger than Chen Xi, with a monthly subsidy of three hundred yuan, basically no need to pay for it at home, of course, the Chen family is not short of this money now.

The changes of the Chen family are obvious to all, the people in the village are a little dazzled, before and after just over a month, the Chen family has undergone earth-shaking changes, and the people nearby have said anything, but most of the reasons fall on Chen Qiaoshan, and they have pulled Chen's mother to say that she gave birth to a good son.

Chen Qiaoshan is very satisfied with the changes of the Chen family, the well-drilling team is on the right track, although Lao Song has left, but Wang Dachun is still there, the well-drilling team has learned almost, and if you have any questions, you can contact them at any time, and there is nothing to worry about.

Chen Qiaoshan was bored at home, so he thought about tutoring the third and fourth children's English, he was very self-aware, and he still had a little confidence in English, fortunately, his grades were enough to fool people, Chen Xi and Chen Wan both obediently followed the study, and the effect was not bad.

Learning still has to rely on accumulation, overnight is not much effect, Chen Qiaoshan thought about whether to buy an MP3 for the two of them, usually follow the learning English if there is nothing to do, but this year, the teaching materials and teaching aids are equipped with tapes, and there are very few CDs, so just give up, if you really buy MP3, you will listen to the song, which will definitely provoke Tao Xiuying to complain.

Xiao Wu has been working hard recently, the final exam of primary school is a little late, and the little girl has been working very hard recently, even Chen's mother was surprised, and she said that she had never been so attentive since she was a child.

Of course, there is a reason why Xiao Wu works hard, and the little aunt and grandmother are not easy to fool, so they dangled in front of Chen Qiaoshan twice in three days, reminding him not to forget the original promise, which made Chen Qiaoshan cry and laugh.
