Water lead-level falls below federal limit in Flint
Wednesday, 25 January 2017 12:11 

 LANSING, Mich. (AP) — Flint's water system no longer has levels of lead exceeding the federal limit, a key finding that Michigan environmental officials said Tuesday was good news for a city whose 100,000 residents have been grappling with the man-made water crisis.

The 90th percentile of lead concentrations in Flint was 12 parts per billion from July through December, below the "action level" of 15 ppb, according to a letter from the Michigan Department of Environmental Quality to Flint's mayor. It was 20 ppb in the prior six-month period.

Based on the sample of 368 residential sites, Flint's lead levels are again comparable to other similarly sized U.S. cities with older infrastructure, state officials said.

"This is good news and the result of many partners on the local, county, state and federal levels working together to restore the water quality in the City of Flint," the department's director, Heidi Grether, said in a statement. "The Flint water system is one of the most monitored systems in the country for lead and copper, and that commitment will remain to ensure residents continue to have access to clean water."

Residents, whose mistrust in government remains high nearly three years after a fateful switch of Flint's water source in April 2014 while the city was under state management, are being told to continue using faucet filters or bottled water because an ongoing mass replacement of pipes could spike lead levels in individual houses. The replacement of the lines is expected to take years.

Tuesday's announcement drew immediate skepticism from some residents.

Melissa Mays said it "means nothing. There's still lead in the system."

"Especially with disruptions, main breaks — pieces of lead scale will be breaking off until these pipes are replaced," Mays said. "You cannot tell me the water is safe because you have not tested every home."

Flint's public health emergency began when lead from old pipes leached into the water supply because corrosion-reducing phosphates were not added due to an incorrect reading of federal regulations.

Elevated levels of lead, a neurotoxin, were detected in children, and 12 people died in a Legionnaires' disease outbreak that experts suspect was linked to the improperly treated water. An ongoing investigation has led to charges against 13 current or former government officials, including two managers who Republican Gov. Rick Snyder appointed to run the city.

Snyder has apologized for the crisis.

"The remarkable improvement in water quality over the past year is a testament to all levels of government working together and the resilient people of Flint helping us help them through participation in the flushing programs," he said in a statement. "There is still more work to do in Flint, and I remain committed to helping the residents recover and restore their city."

Armed with the new numbers, state attorneys asked a judge Tuesday to drop a Nov. 10 order that directs Michigan and Flint to inspect home filters and deliver bottled water if necessary. Assistant Attorney General Michael Murphy said thousands of homes have been visited, but he acknowledged that the state has not determined how to acquire, store and deliver water as the judge instructed.

"They're treating the order as a suggestion," Dimple Chaudhary, a lawyer with the Natural Resources Defense Council, said, urging U.S. District Judge David Lawson to keep the injunction in place.

Lawson did not make an immediate decision, although he said the state appeared to be "slow-walking" compliance.

While it is important for cities to be below the federal limit, experts say there is no safe level of lead and the crisis has exposed gaps in a monitoring system that can mislead individual homeowners and renters into thinking their tap water is safe when only some homes with lead pipes are sampled.

Michigan's letter to Flint Mayor Karen Weaver was reviewed by the U.S. Environmental Protection Agency before it was sent. Weaver called the results "encouraging" but said, "We are not out of the woods yet."

Because the city exceeded the federal limit in the first half of 2016, it must continue replacing at least 7 percent of its lead service lines by June 30.

Though the requirement may be discontinued if the water supply is at or below the limit in the next monitoring period, the state said it would continue supporting Flint's plan to replace all of its lead-tainted pipes. The state set aside $27 million for the project as part of the nearly $300 million that has been allocated toward the crisis, including for bottled water, filters and legal bills.

Tuesday's announcement means the state will soon stop providing a credit on customers' bills. It has been partially covering their bills dating to April 2014. Starting in March, the state also plans to no longer pay for Flint's water, which comes from a Detroit-area system for now. The state has been covering the costs since October 2015.

New EPA Administrator Sworn In

Scott Pruitt Confirmed and Sworn in as EPA Administrator

WASHINGTON--Today, Oklahoma Attorney General Scott Pruitt was confirmed and sworn in as the 14th administrator of the U.S. Environmental Protection Agency (EPA).

Administrator Pruitt believes promoting and protecting a strong and healthy environment is one of the lifeblood priorities of the government, and EPA is a vital part of that mission.

Pruitt became a national leader through a career of advocating to keep power in the hands of hardworking Americans. He has a proven record of working with industry, farmers, ranchers, landowners, small business owners and others to protect our natural resources.

As a dedicated civil servant, Pruitt created policies that serve the people. He strongly believes environmental law, policy, and progress are all based on cooperation among the states, cooperation between the states and EPA, and cooperation between regulators and the public.

As Administrator, Mr. Pruitt will lead EPA in a way that our future generations inherit a better and healthier environment while advancing America’s economic interests. He is committed to working with the thousands of dedicated public servants at EPA who have devoted their careers to helping realize this shared vision, while faithfully administering environmental laws.

Most recently, Administrator Pruitt served as the Attorney General for Oklahoma. He worked with his Democratic counterpart in Arkansas to reach agreement to study the water quality of the Illinois River that crosses between the two states and has been enjoyed by generations of Oklahomans and Arkansans. The Statement of Joint Principles provided for a best science study using EPA-approved methods, with both states agreeing, for the first time, to be bound by the outcome.

During his tenure as Oklahoma’s Attorney General, Mr. Pruitt led an historic water rights settlement between the State of Oklahoma, Oklahoma City and the Choctaw and Chickasaw Nations that preserved the ecosystems of scenic lakes and rivers on native lands. The agreement, which required Congressional approval, was signed into law on December 2016.

The Law provides a framework that fosters intergovernmental collaboration on significant water resource concerns while protecting existing water rights and affirming the State’s role in water rights permitting and administration. Water settlement cases can be lengthy, costly, divisive and disruptive, however under Pruitt’s forward thinking leadership the process was hailed by all parties as one of commitment, hard work, perseverance and cooperation.

As Attorney General for Oklahoma, he also led the State’s legal challenges against property rights intrusion while protecting Oklahoma’s natural resources and environment.

Administrator Pruitt is recognized as a national leader in the cause to restore the proper balance between the states and federal government, and established common sense regulations that are fair and provide relief where needed. Before being elected attorney general, he served eight years in the Oklahoma State Senate where he was a leading voice for fiscal responsibility.

After earning his Bachelor’s Degree from Georgetown College and graduating from the University of Tulsa law school, Pruitt went into private legal practice, specializing in Constitutional Law.

In addition to his life as a civil servant, Administrator Pruitt is a successful entrepreneur. As a co-owner and managing general partner of Oklahoma City’s Triple-A minor league baseball affiliate, the Oklahoma City RedHawks, Mr. Pruitt took over the team’s marketing operations and helped the team become one of the league’s leaders in attendance and merchandise sales.

Scott Pruitt is, first and foremost, a family man. Scott and Marlyn, his wife of 27 years, proudly raised their daughter, McKenna, and son, Cade, in Tulsa. Scott has made it a priority to pass on to his children the same principled, family values with which he was raised.
