The water that Flint used to get from nearby Detroit was treated with phosphate ions in this way and, as a result, remained relatively free of lead ions. When Flint changed its water supply to river water, authorities failed to treat it with phosphate ions, so the phosphate crust broke down over time and lead ions entered the water.

What are the chemicals in water?
Trihalomethanes are just one group of chemicals associated with water contamination, lead is another. Lead was a popular choice for use as water pipes for centuries. The Romans used the dense metal because of its durability and malleability. Water pipes are no longer made from lead, but older cities, such as Flint, still rely on lead pipes—in addition to those made from copper and iron—to transport water to people’s homes. No one knows exactly how many lead pipes are used in the United States, but the number is in the millions. In addition to the pipes themselves, lead is also found in alloys (mixtures of metals) in other parts of the plumbing system. For example, the solder used to join pipes together is an alloy of tin and lead.
Why is the Flint River water so high in chloride?
First, the Flint River water had some unusually high levels of chloride ions, which can accelerate the corrosion of the pipes.

This is actually an example of connections between different applications of chemistry: De-icing Michigan’s slippery roads has some immediate and obvious benefits, but the run-off of chloride ions can be an unintended consequence.

F lint, through emergency management, might have been suffering a deficit of democracy, but its people found other ways of standing up for their community.

Frustrated with stunted wages, dangerous conditions and the company’s efforts to intimidate them from forming a union, workers occupied two auto plants on 30 December 1936. Refusing to leave or work, they staged concerts and lectures, while supporters delivered food and picketed outside. The strike spread to a third plant in February. With workers staying inside, it was impossible for the company to hire replacements and get the lines moving again. GM tried turning off the heat to freeze the strikers out, but they remained, burning burlap to stay warm. It took 44 days, but GM eventually announced a $25m wage increase and recognition of the union’s right to organise – a first for the US’s auto industry.
