Pesticides are chemicals that are used to exterminate or reduce the presence of pests such as insects, rodents, fungi, and any unwanted plant growth. Even though the use of pesticides is helpful in some ways, it has the negative aspect of polluting groundwater and healthy water through leaching, spills, and misuse of disposal techniques. Of course, using healthy water contaminated with pesticides can be hazardous to human health, especially if one is exposed to it for a long time. This article focuses on the pesticide contamination of healthy water and methods to eradicate the same.
Possible Health Problems Due to Pesticides in Wells
Acute Health Effects
Drinking well water containing high levels of pesticides may lead to acute effects or effects that can be observed immediately. Some signs may be headache, dizziness, nausea and vomiting, diarrhea, blurred vision, shaking and convulsions, and unconsciousness. A possible effect of very high doses is the paralysis of the respiratory center, resulting in death. The segment of the population such as pregnant women, young children, the elderly, and people with underlying health conditions are more at risk for serious conditions.
Chronic Health Effects
Contamination of healthy water by pesticides is also dangerous if consumed over a long term. Studies have established that pesticides cause increased risks of cancers such as leukemia and lymphoma, brain and breast, ovarian and prostate, testicular and liver cancers. Research also shows that humans exposed to pesticides through drinking water may be at high risk of endocrine disorders, reproductive complications, neurological disorders, liver and kidney disorders, a weak immune system, and congenital anomalies. Children are especially vulnerable.
Specific Pesticides of Concern
Some of the pesticides found to be present in healthy water require unique handling and extra caution. The most commonly used pesticides that contain these chemicals include insecticides such as aldicarb, DDT, chlordane, carbofuran, and chlorpyrifos, herbicides such as atrazine, alachlor, 2,4-D, and glyphosate, and fungicides such as pentachlorophenol and PCNBs. Since these chemicals are toxic and can remain in the groundwater source for a long time, testing is very important to detect early.
Decoding the Process of Purification of Healthy Water Contaminated with Pesticides
Testing Well Water
It is quite unfortunate that dissolved pesticides do not have any smell or color. Therefore, testing is the only way to confirm that water is contaminated. Scientists advise that well water be tested at least once a year. Detecting pesticides more often may be recommended if you reside in an agricultural region or have prior evidence of detecting pesticides. Always make sure you go for the services of a laboratory accredited by the state.
Water Treatment Solutions
There are different treatment methods to filter out pesticides from drinking water. Thus, the approach to be followed will depend on matters such as the type of pesticide(s), concentration, and water. The most well-known choices include granular activated carbon filters, reverse osmosis systems, oxidizing filters, distillation units, and anion exchange resins. Pre-treatment, such as sediment filters, increases the effectiveness of the setups. Treatment systems are supposed to be regularly maintained, and the filters should be replaced now and then for the system to work.
Reducing Sources of Pesticide Content in the Environment
It is also essential to reduce the potential risks of contamination to ensure safe, healthy water in the long run in addition to water purification. Get your well checked to determine if there are cracks through which pesticides could penetrate and contaminate the water. Stay alert to other pesticide uses nearby, for instance industrial usage, and support measures to prevent groundwater contamination. Also, correctly dispose of household pesticides without disposing of them near the well at home. When these preventive measures are put in place, it makes it easy to safeguard the quality of the well water.
Conclusion
Contaminants found on the surface in the form of spillage, runoff, or due to groundwater leaching can contaminate water used in wells for drinking, cooking, bathing, and other purposes. Drinking water containing pesticides--even in low amounts--has associated health hazards, more so with children and those who have long-term exposure. Contaminated well water poses a threat to people’s health and well-being; therefore, frequent testing helps in earlier detection and treatment.
Pesticides can be eliminated in the next phase of water treatment through activated carbon filtration or reverse osmosis treatments after identifying unsafe waters. Thus, desensitization should be accompanied by prevention measures to give the best safeguarding plan. Well water testing, and taking necessary measures if pesticides are found in your well water, is the best preventive measure that you will need to embrace in the future.
