Technical and Biological Problems Follow Renovation of the Lincoln Memorial Reflecting Pool
林肯紀念堂反思池翻新後出現技術與生物問題
Introduction
A multi-million dollar renovation of the Lincoln Memorial Reflecting Pool has faced serious technical problems, including the peeling of the basin floor and the rapid growth of algae.
林肯紀念堂反思池的一項耗資數百萬美元的翻新工程面臨嚴重的技術問題，包括池底塗層剝落以及藻類快速生長。
Main Body
The renovation was part of a larger plan to improve the appearance of Washington, D.C., before the United States' 250th anniversary. The project involved applying a deep blue sealant called 'American Flag Blue.' This work was completed by Atlantic Industrial Coatings under a no-bid contract, and the cost rose from an initial estimate of $1.8 million to about $14.7 million. Shortly after the pool was refilled, the water turned green due to algae. Consequently, the Department of the Interior used National Park Service staff to apply hydrogen peroxide and install a 'nano bubble' filtration system. This system was provided by Green Water Solutions, a company owned by a political donor, through another $1.7 million no-bid contract.
這次翻新是一個更大計劃的一部分，目的是在美國 250 週年前改善華盛頓特區的面貌。該項目使用了名為「美國之旗藍」的深藍色密封劑。這項工程是由 Atlantic Industrial Coatings 透過一份無需招標的合約完成，成本從最初估計的 180 萬美元增加到約 1,470 萬美元。池水重新注滿後不久，便因藻類而變綠。因此，內政部派遣國家公園管理局的人員施加過氧化氫，並安裝了一套「納米氣泡」過濾系統。該系統由一名政治捐款人擁有的公司 Green Water Solutions 提供，同樣是透過另一份 170 萬美元的無需招標合約獲得。
Technical experts believe that several factors caused the sealant to peel within two weeks. They suggest that the dark blue color absorbed too much heat, which raised the water temperature and encouraged algae to grow. Furthermore, the use of strong chemicals like hydrogen peroxide may have damaged the bond between the coating and the concrete. Other possible causes include poor surface preparation and damage from UV rays.
技術專家認為，有數個因素導致密封劑在兩週內剝落。他們認為深藍色吸收了過多熱量，導致水溫升高並促進藻類生長。此外，使用過氧化氫等強效化學品可能會損壞塗層與混凝土之間的黏著力。其他可能的原因包括表面準備不足以及紫外線的傷害。
These failures have led to legal and political conflicts. The Cultural Landscape Foundation has started a lawsuit, asserting that the administration skipped necessary preservation reviews to finish the project faster. While the administration emphasizes that the changes were legal and that the cleanup is working, critics argue that the project was a waste of money and showed a lack of professional supervision.
這些失敗導致了法律與政治衝突。文化景觀基金會（Cultural Landscape Foundation）已提起訴訟，主張行政部門為了加快項目進度而省略了必要的保護審查。儘管行政部門強調這些變更是合法的且清理工作有效，但批評者認為該項目浪費公帑，且顯示出缺乏專業監督。
Conclusion
The Lincoln Memorial Reflecting Pool is still undergoing maintenance as the administration tries to fix the sealant and remove the algae before the July 4 celebrations.
林肯紀念堂反思池目前仍在進行維修，行政部門試圖在 7 月 4 日慶祝活動前修復密封劑並清除藻類。
Vocabulary Learning
⚡ The 'Cause & Effect' Engine
To move from A2 (simple sentences) to B2 (complex flow), you must stop using 'and' and 'so' for everything. The article shows us how professionals link a problem to a result using a variety of 'bridge' words.
🛠️ The Logic Shift
Look at this simple A2 thought: The water was hot and the algae grew.
Now, look at how the text elevates this to B2:
"...the dark blue color absorbed too much heat, which raised the water temperature and encouraged algae to grow."
Why this works:
- The word 'which' acts as a hook, attaching the result directly to the cause without starting a new sentence.
- The verb 'encouraged' is more precise than 'made.' It suggests a process.
🚀 Power Connectors found in the text
Instead of using 'because' or 'then', try these B2-level transitions used in the report:
- Consequently (Use this instead of 'So')
- Example: The sealant peeled. Consequently, the government spent more money.
- Due to (Use this to introduce a reason quickly)
- Example: The water turned green due to algae.
- Furthermore (Use this to add a second, stronger reason)
- Example: The heat was a problem. Furthermore, the chemicals damaged the concrete.
💡 Pro Tip for Fluency
When describing a mistake or a technical failure, don't just say 'it happened.' Use the [Cause] [Bridge Word] [Result] formula:
Poor surface preparation led to the sealant peeling.
