Small-Scale Question Sunday for June 21, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Before I waste any more of my time thinking about this, is there any evidence that the degradation of the new reflecting pool coating was caused by vandalism as opposed to run-of-the-mill incompetence?

I don’t really care about the algae. That seems like a fixable problem.

I personally think it's incompetence. And even worse, it's incompetence due to corruption.

But in an effort to be charitable: somebody certainly made "giant ‘8647’ markings on National Mall" and that's vandalism, so can't rule out the same for the pool as well.

Here's CNN reporting that the water in the pool has elevated phosphate. My understanding is that one of the more straightforward ways you'd get elevated phosphate in the water is by dumping phosphate fertilizer into the water. Given the other evidence of deliberate vandalism, I'm not sure why incompetence or corruption are supposed to be the leading hypothesis here.

I'm open to being corrected if there's some other explanation.

Runoff from the vast area of lawn that drains into the reflecting pool.

Is that how the water system in question works? If so, I'd have thought I'd have heard of it by now, but again, I'm willing to be corrected if there's clear facts available.
