The Lincoln Memorial pool is green. Small plants called algae are growing in the water. Workers are using chemicals to clean it.

林肯紀念館的水池變綠了。水中生長著一種稱為藻類的小植物。工人正使用化學藥劑進行清理。

The government spent a lot of money to fix the pool. They wanted the water to look like a blue flag. They worked very fast. Now, the warm summer water helps the green algae grow.

政府花了很多錢來修復水池。他們希望水色看起來像藍色的旗幟。他們工作速度很快。現在，夏季溫暖的水分助長了綠藻的生長。

Workers put hydrogen peroxide and ozone in the water. These chemicals kill the algae. One scientist says this is only a short fix. The water does not move fast. Slow water helps algae grow.

工人向水中加入過氧化氫和臭氧。這些化學藥劑可以殺死藻類。一名科學家表示，這僅僅是短期方案。水流速較慢，而緩慢的水流有助於藻類生長。

This pool is very famous. Many people visited it for important protests in the past. But the pool always has this problem. Birds and rain bring more algae into the water.

這個水池非常有名。過去許多人在這裡參與重要的抗議活動。但這個水池一直存在這個問題。鳥類和雨水將更多藻類帶入水中。

Workers are still cleaning the pool. They want the water to look clear and still.

工人仍在清理水池。他們希望水質看起來清澈且平靜。

The Lincoln Memorial Reflecting Pool has seen a rapid growth of algae shortly after a multimillion-dollar renovation. As a result, officials have had to use chemical treatments to make the water clear again.

林肯紀念館反思池在耗費數百萬美元翻新後不久，便出現藻類快速生長的現象。因此，相關部門不得不使用化學處理使水質重新恢復清澈。

This ecological problem follows a major renovation ordered by the Trump administration, which wanted the pool to have a specific 'American flag blue' color. This project aimed to fix problems from a previous 2012 renovation. However, because the recent work—including draining, painting, and refilling—was done so quickly, the water quality systems may not have stabilized. Consequently, the warm early-summer water caused algae to grow rapidly.

這個生態問題源於川普政府要求的大規模翻新，當時政府希望池水呈現特定的「美國國旗藍」。該計畫旨在修正 2012 年前一次翻新所留下的問題。然而，由於近期工程（包括排水、塗漆和重新注水）執行速度過快，水質系統可能尚未穩定。因此，初夏溫暖的水溫導致藻類快速生長。

To solve this, the National Park Service is using hydrogen peroxide and 'nanobubble' ozone systems. While officials emphasized that hydrogen peroxide is a milder option than chlorine, some experts question if it can work for a pool holding 6.5 million gallons. Marine biologist Christopher Lowe asserted that while this chemical bleaches the algae, it breaks down quickly into oxygen and water. Therefore, it is only a temporary fix rather than a permanent solution. Furthermore, because the pool needs still water to create a mirror effect, it naturally encourages algae to grow.

為了改善此狀況，國家公園管理局正採用過氧化氫與「奈米氣泡」臭氧系統。雖然官方強調過氧化氫比氯更溫和，但部分專家質疑這是否適用於容積達 650 萬加侖的池水。海洋生物學家 Christopher Lowe 主張，儘管這種化學物質能漂白藻類，但它會迅速分解為氧氣和水。因此，這僅是臨時補救措施，而非永久解決方案。此外，由於該池需要靜止的水面以創造鏡像效果，這在自然條件下便會促使藻類生長。

Historically, the pool has been the center of important events, such as the 1963 March on Washington. Despite its importance, the site has struggled with algae for over a hundred years. Although the current chemicals are safe for people and wildlife, they may turn the pool into an 'ecological desert' by killing off aquatic organisms. Additionally, birds and rainwater continue to bring new algae into the water, making the problem difficult to stop completely.

從歷史上看，該池一直是重要事件的中心，例如 1963 年的華盛頓大行軍。儘管地位重要，但該遺址與藻類鬥爭已超過一百年。雖然目前的化學藥劑對人類和野生動物安全，但可能會因殺死水生生物而將池內變成「生態沙漠」。此外，鳥類和雨水會持續將新藻類帶入水中，使得問題難以完全根除。

The reflecting pool is still being treated with chemicals to fight the algae, but long-term success depends on finding a balance between the desired visual look and biological management.

反思池目前仍在使用化學藥劑對抗藻類，但長期成功與否，取決於能否在追求視覺效果與生物管理之間取得平衡。

The Lincoln Memorial Reflecting Pool has experienced a rapid algal bloom shortly after the completion of a multimillion-dollar renovation, necessitating the application of chemical treatments to restore water clarity.

林肯紀念館反思池在耗資數百萬美元的翻新工程完成後不久，便出現了快速的藻類爆發，因此需要採取化學處理以恢復水質透明度。

The current ecological instability follows a comprehensive refurbishment ordered by the Trump administration, which sought to implement a specific 'American flag blue' aesthetic through resurfacing and infrastructure repairs. This project was intended to rectify perceived deficiencies in a prior 2012 renovation conducted during the Obama administration. However, the compressed temporal framework of the recent overhaul—encompassing draining, painting, and refilling—may have precluded the thorough stabilization of water quality systems, thereby facilitating the rapid proliferation of algae upon the introduction of warmed early-summer water.

目前的生態不穩定源於川普政府下令進行的全面翻新，旨在透過重新鋪面與基礎設施維修，實現一種特定的「美國國旗藍」美學。此項目旨在修正 2012 年歐巴馬政府期間翻新時被認為不足之處。然而，近期大修的時間表過於緊湊——涵蓋排水、塗漆與重新注水——可能導致水質系統未能徹底穩定，從而在引入初夏暖水後促使藻類快速增生。

To mitigate the bloom, the National Park Service and contracted personnel have commenced the administration of hydrogen peroxide and 'nanobubble' ozone systems. While officials characterize hydrogen peroxide as a milder alternative to chlorine, its efficacy at the scale of the pool's 6.5-million-gallon capacity has been questioned. Marine biologist Christopher Lowe posits that while the oxidizing agent facilitates the bleaching of algae, its rapid degradation into oxygen and water renders it a transient solution rather than a permanent preventative measure. Furthermore, the systemic requirement for a mirror-like surface necessitates slow-moving water, a condition that inherently optimizes algal growth and creates a persistent tension between aesthetic requirements and biological control.

為了緩解藻類爆發，國家公園管理局與承包人員已開始啟用過氧化氫與「奈米氣泡」臭氧系統。雖然官員將過氧化氫描述為比氯氣更溫和的替代方案，但其在反思池 650 萬加侖容量規模下的效能受到質疑。海洋生物學家 Christopher Lowe 指出，雖然氧化劑有助於漂白藻類，但其迅速分解為氧氣與水的特性，使其成為暫時性的解決方案而非永久性的預防措施。此外，為了維持鏡面效果，水流必須緩慢，而此條件天生便最有利於藻類生長，導致美學要求與生物控制之間存在持久的緊張關係。

Historically, the pool has served as a focal point for significant socio-political events, including the 1963 March on Washington and various subsequent civil rights demonstrations. Despite its cultural prominence, the site has been plagued by recurrent algal blooms for over a century. The current reliance on chemical dosing, while deemed safe for nearby humans and wildlife, may result in the pool becoming an 'ecological desert,' as repeated treatments limit the viability of aquatic organisms. The persistence of the issue is further exacerbated by external vectors, such as avian transport and runoff, which ensure the reintroduction of algae regardless of sterilization efforts.

從歷史上看，該池一直是重大社會政治事件的焦點，包括 1963 年的華盛頓大遊行以及隨後多次民權示威。儘管具有重要的文化地位，該場地一個多世紀以來一直飽受反覆藻類爆發之苦。目前依賴的化學劑投藥雖然被認為對周邊人類與野生動物安全，但可能會使池內變成「生態沙漠」，因為重複處理限制了水生生物的生存能力。外部媒介（如鳥類傳播與逕流）進一步加劇了問題，確保無論採取何種滅菌措施，藻類仍會被重新引入。

The reflecting pool remains under active chemical treatment to counteract the algal bloom, though long-term stability remains contingent upon the balance between aesthetic stillness and nutrient management.

反思池目前仍處於積極的化學處理中以對抗藻類爆發，但長期穩定性仍取決於美學上的靜謐要求與營養管理之間的平衡。
