1 Groundwater contamination.
2 Groundwater contamination is often gradual and deep, and it is difficult to detect it in time. Even if they are found, it is difficult to eliminate contaminants.
3. It cannot be deleted often does not exclude special cases and the language is accurate.
4 Examples illustrate the difficulty of eliminating groundwater once it is contaminated.
5. Treat industrial sewage, agricultural sewage, and domestic sewage.
-
11 (1) Wastewater and garbage discharged from industrial production processes; (2) chemically synthesized pesticides; (3) urban domestic sewage;
4) A large amount of household waste generated by the increase in the world's population. (1 point for answering 1 point).
12.(1) Explain that the pesticide is not exactly 10% absorbed by crops, which indicates the approximate meaning and reflects the accuracy of the explanatory language.
2) The specific and accurate description of the situation of "river pollution in China" is very large, not optimistic, and the consequences are serious, which reflects the accuracy of the explanatory language.
13.The groundwater pollution movement is slow and difficult to detect in time; Groundwater is difficult to treat and takes a long time to be effective; It causes harm to the human body and even affects the health of several generations. (2 points are awarded for answering one point).
14.Examples: For some enterprises with serious pollution, it is necessary to implement a time limit for treatment; do a good job in the comprehensive utilization of chemical resources to reduce the harm of pesticides to groundwater; put an end to the generation of new sources of pollution in the city; According to the actual local situation, establish a sewage treatment project.

11 In the context of the text, what are the main causes of groundwater pollution? Please summarize it in points. (4 marks)12 Contextually point out the role of punctuated words in the following sentences.
4 points) (1) After years or even decades of use, only about 10% of these pesticides are absorbed by crops.
2) According to statistics, more than 80% of China's rivers are polluted, and some of them are so polluted that they cannot even be used to irrigate farmland.
13 Why should we attach great importance to the management of the groundwater environment? Please provide a brief explanation. (2 marks)14 An organization wants to formulate a measure on the issue of "groundwater treatment", please help complete the following ** according to the content of the article. (2 points).
1) Strengthen the strength and strengthen the supervision and monitoring work. (2) Adjust the industrial structure and deepen the environmental management of enterprises. (3) (4) (5) Implement total pollutant discharge control to reduce the total amount of pollutant discharge.
6) Adopt the method of artificial recharge of groundwater to alleviate the contradiction between groundwater supply and demand.

I've only heard about water to know the answer.
Groundwater is not pumped forever. Groundwater is formed by the continuous circulation of subsoil and surface water, so the recharge and extraction of groundwater also requires certain time and conditions. If groundwater is pumped excessively, the groundwater level will drop dramatically, leading to the depletion of groundwater. >>>More
Groundwater is very scarce, so it is a rare environmental resource, and its catastrophic is the groundwater inrush disaster. >>>More
