For nearly a year and a half, thousands of Flint residents drank water contaminated with lead poising. There are a lot of children facing health problems because of this water and people have died from Legionnaires’ disease believed to be caused by the water.

Something needs to change as soon as possible.

According to new reports, blood lead levels for children under the age of 5 doubled from 2.1% to 4%. The water looks brownish yellow in certain places of Flint because of the lead. Those who have already suffered from health problems are at risk and others may be in the future, depending on how bad their conditions are.

Flint mayor Karen Weaver said it will take more than $1.5 billion to repair the city’s water infrastructure. In early February, she announced a plan to begin replacing water pipes causing the lead poisoning. There have also been nationwide donations to the Flint Child Health and Development Fund to recover the short long-term costs of the crisis.

Solutions to this situation will be expensive, but at the same time it’s going to be worth it.
