The water is circulating between the reflecting pool and the Tidal Basin. It was part of the 2009 upgrade to use that instead of using tap water.

They don’t typically circulate anything back to the tidal basin, the reflecting pool’s circulation system from the 2009 upgrades is a closed loop that filters the water and sends it back to the pool.

They have an option to top off the pool from the tidal basin to combat leaks/evaporative loss, but they don’t typically use that option during this time of the year (because the tidal basin is full of algae), and as far as I know they never use that method to completely refill it.

When it’s filled from empty, it’s treated water from DC Water.

It actually is filled with standard tap water from DC Water.

After zooming in, I do see that they say 12% hydrogen peroxide, which is the typical cleaning grade.

With enough H2O2, about 6,500 gallons in this case, they can definitely kill the algae (for a time being, the H2O2 won’t last long before breaking down, and then you’ll get another algae bloom). The dead algae will lose its green color and settle on the bottom.

The bigger question is how it will react with the algaecides that are also meant to be in the pool.

If the Trump team isn’t involved and it’s just NPS acting on its’ own, it might be well thought out: shock the pool with H2O2 to kill the algae and reset, then get ahead of the next bloom with a larger algaecide does to compensate for the warmer waters created by the darker bottom.

Are we sure it’s hydrogen peroxide? Even before Trump NPS regularly added algaecides.

If it is H2O2, it will react with the chloramine that’s in the water and both the hydrogen peroxide and the chloramine will be neutralized. It wouldn’t take much, 50-100 gallons of H2O2 would be enough to neutralize all the chloramine in the pool.

But to both neutralize the chloramine and reach enough hydrogen peroxide to effectively kill the algae, they’d probably need around 1 gallon H2O2 per 10,000 gallons of water, so around 6,675 gallons of H2O2.

Democrat voters are anti-war crime. Whodda thought.

USPS is not a business, and therefore not required to be profitable.

Furthermore, USPS’s financial problems that consistently make headlines were manufactured by a 2006 federal act that required them to prefund health and retirement benefits 75 years in advance. The policy was a republican gift to private shipping companies (UPS, FedEx, etc), it was repealed under Biden.

Although they are still stuck with the contract Trump 1 saddled them with for awful and expensive delivery vehicles.

After completely destroying the IRGC and Navy within the first week of the special military operation, 3 months later we will have a concept of a plan for total victory in 2 weeks.

Is Platner a great candidate? No.

Is he better than Collins? Almost certainly.

A Heritage Foundation hit piece is a ringing endorsement as far as I’m concerned.

I especially enjoyed the part about how this adult presented a diary entry she wrote ‘from 2016’ as her evidence.

“Newly Released” aka: dump the bodies.

Because “Restoring Law and Order” is a dog whistle for systematically racist policing.

I can guarantee that a city like Baltimore will not see a dollar of this even though the City’s tactics have brought about a historic crime reduction without significantly increasing police spending (For reference, Baltimore has reduced it’s homicide rate by about 72% in just 4 years).

None of this is accurate:

Generally the wear on tires is proportional to the wear on roads, since both are effectively grinding against each other with grit as the grinding medium in between. It would be harder to find a more accurate way to measure an individual vehicle’s contribution to road wear, given that weight is such a large factor.

Surface wear on roads from tire contact is not a concern, the damage is done due to a combination of compression cycles (the 4th power law) and weather. The 4th power law being that road wear is equal to the 4th power of the axel load.

Your tire wear rate is based on so many unique factors, with vehicle weight being a relatively minor one. Force of accel/decell/turning, suspension tuning, tread, rubber compound, road material, etc.

Your tire rubber is not grinding away the road surface. It’s wild that I even have to say that.
