California Proposition 65

What's in your Well ?

Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires the state to maintain and update a list of chemicals known to the state. Enacted as a voter initiative in November 1986, Proposition 65 protects the state’s drinking water sources from being contaminated with chemicals that are known to cause cancer, birth defects, or other reproductive harm.

The list of chemicals under Proposition 65 contains a wide range of naturally occurring and synthetic chemicals that are a part of our everyday use. These chemicals include additives or ingredients in pesticides, common household products, food, drugs, dyes, or solvents.

Improving power and water systems

The package invests $65 billion to rebuild the electric grid, according to the White House. It calls for building thousands of miles of new power lines and expanding renewable energy, the White House said.

It provides $55 billion to upgrade water infrastructure, according to the text. It will replace lead service lines and pipes so that communities have access to clean drinking water, the White House said.

Another $50 billion will go toward making the system more resilient -- protecting it from drought, floods and cyberattacks, the White House said.
