The proposal, called the lead and copper rule improvements, would for the first time require utilities to replace lead pipes even if their lead levels aren’t too high.

“We can make a lead-free future a reality for all, no matter the color or their skin or their zip code,” it said. Cory Booker, D-N.J., representing states that have faced lead crises, agreed in a joint statement, citing both the new rule and the Biden administration’s infrastructure investments. “We’re bending the arc towards equity and justice on this legacy issue.” “We’re trying to right a longstanding wrong here,” said Radhika Fox, head of the EPA Office of Water.

The Biden administration says investment is vital to fix this injustice and ensure everyone has safe, lead-free drinking water. After the crises, tap water use declined nationally, especially among Black and Hispanic people. Their impact reaches beyond public health. Lead crises have hit poorer, majority-Black cities like Flint especially hard, propelling the risks of lead in drinking water into the national consciousness. They are most common in older, industrial parts of the country. Lead pipes connect water mains in the street to homes and are typically the biggest source of lead in drinking water. The Biden administration has previously said it wants all of the nation’s roughly 9 million lead pipes to be removed, and rapidly. “These improvements ensure that in a not too distant future, there will never be another city and another child poisoned by their pipes,” said Mona Hanna-Attisha, a pediatrician and clean water advocate who raised early alarms about Flint. Pulling it off will require overcoming enormous practical and financial obstacles. It is the strongest overhaul of lead rules in more than three decades, and will cost billions of dollars. Millions of people consume drinking water from lead pipes and the agency said tighter standards would improve IQ scores in children and reduce high blood pressure and heart disease in adults. cities would have to replace lead water pipes within 10 years under strict new rules proposed by the Environmental Protection Agency as the Biden administration moves to reduce lead in drinking water and prevent public health crises like the ones in Flint, Michigan and Washington, D.C. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.WASHINGTON (AP) - Most U.S. Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate.

Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). 'Reflectivity' is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
