Scientists suspect hydrogen first met oxygen and formed water amid interstellar clouds as the earliest stars began to die, a billion years after the creation of our universe. With that perspective in mind, the city of San Diego’s plan create a third of the city’s drinking water from recycled sewage isn’t taking that long. But it is definitely delayed. That’s thanks to a dispute between non-union contractors and the city. In November, the City Council required builders looking to work on a big part of the water recycling project, known as Pure Water, to agree to union-friendly contracts.
