It’s ruined in the short term for sure. It’s a reflecting pool, not a swimming pool. It’s supposed to be dark, not light blue.

It’s my understanding it is fed with water from the Potomac, so there is no way to keep it blue, there are no filtration systems in place that they can add chlorine to. So the pool will end up turning black again, it will just look patchy and ugly.

It’s so on the nose for this asshole who is unable to engage in self reflection at all to ruin the reflection pool because he doesn’t understand what it’s for and thinks, “pools need to be blue!”.
