While the City of Asheville has restored potable water to its 63,000 customers, it’s still struggling with high turbidity at its main reservoir, North Fork.

Filtering that cloudy water remains a challenge, but major assistance is on the way this week in the form of a $39 million six-month project spearheaded by the Army Corps of Engineers to install a mobile filtration system at the reservoir. The city and the Corps planned to start testing the system this week, and Asheville Water Resources spokesperson Clay Chandler said it should be operational by Friday.

Chandler addressed the plan at the Monday Tropical Storm Helene briefing and then answered followup questions via email. Plans call for the system, which will be run by a contractor, to run continuously at North Fork Reservoir, which is located outside of Black Mountain and provides water to 80 percent of the city’s residents.

“Its production will start small, around 5 million gallons per day, and ramp up from there,” Chandler said. “Eventually, the Corps of Engineers system will do most of the heavy lifting, with North Fork’s existing processes providing support, to produce the average daily demand of 20-25 million gallons of water.”

The city restored untreated water to most customers in mid-October and potable water Nov. 18. But turbidity remains a concern.

“While North Fork has been able to meet system demand on its own for several weeks, we’re still one snowstorm or other especially windy weather event from the turbidity becoming unmanageable for our existing treatment processes,” Chandler said. “The Corps of Engineers system will provide a critical layer of security that will keep our customers in water should that happen.”

Chandler said the Federal Emergency Management Agency will cover the cost of the project.

Army Corps of Engineers spokesperson Patrick Moes said the North Fork Reservoir Turbidity Reduction Project contract was awarded to Ahtna/CDM Smith on Nov. 8.

“With respect to the design of the project, we provided the holistic performance requirements such as a gallons per day requirement (25 million), pumping requirements, etc., and the contractor executed the plan,” Moes said via email.

“The $39.2 million contract is for six months, with options to extend the work beyond the initial performance effort. The extension options include two additional six-month intervals, but we have not had those discussions at this point.”

Ahtna and CDM Smith have worked together on other projects. Ahtna’s website states the corporation is “one of 13 Alaska Native Regional Corporations established by Congress under terms of the Alaska Native Claims Settlement Act of 1971.

“Based in Glennallen, Alaska, Ahtna, Inc. is owned by more than 2,000 shareholders, the majority of whom are of Ahtna Athabascan descent,” the site continues. “Many Ahtna shareholders still reside in the Ahtna region, the traditional homeland of the Ahtna people.”

Ahtna’s subsidiaries provide a range of services across many industries, construction and government contracting, according to the website. It works in all 50 states.

CDM Smith is a privately owned engineering and construction company that offers service in “water, environment, transportation, energy and facilities,” according to its website. Its world headquarters is in Boston.

After Helene caused extreme flooding and heavy runoff into North Fork, on Sept. 27, essentially turning the 350-acre lake upside down, the measurement of turbidity, Nephelometric Turbidity Units (NTUs), stood at 79. The raw water coming into North Fork, which is surrounded by a largely undeveloped 20,000-acre watershed, usually has a measurement around 1. By Monday it had dropped to 12.7.

The city has taken several measures to reduce turbidity, including three rounds of in-lake chemical treatments to help sediment coagulate and sink, and the installation of “turbidity curtains” designed to help still the water and foster coagulation of clay particles.

With the Army Corps’ help in constructing a pilot plant at North Fork to see what level of turbidity the reservoir’s direct filtration system can handle, the city discovered it was able to filter and treat higher turbidity water than previously thought. Initially, the city said turbidity would have to drop to the 1.5-2.0 level before treatment began, but it realized via the pilot plant that it could treat water with NTU levels in the teens.

The three in-reservoir treatment applications at North Fork involved dispersing aluminum sulfate, a coagulant, and caustic soda, which regulates the water’s pH levels to ensure optimum coagulation and sinking of clay particles. The turbidity improved, but it has been slow going: It remained in the 20s through October before dropping into the teens in November.

The water coming to customers’ taps is potable now and has a very low turbidity level, about .1, the city said previously. That’s well under EPA requirements.

‘Seasonal flip” may help turbidity

On Monday, Chandler noted another phenomenon that could help with turbidity: “the seasonal flip.”

“So, when the water gets really cold, like it’s about to get because it’s really cold outside, it does exactly like the term ‘flip’ sounds. It takes everything that’s on or near the bottom and puts it near the top, and takes everything that’s at or near the top and puts it on the bottom,” Chandler said. 

The city is fairly certain that a seasonal flip occurred at the Bee Tree Reservoir in the past few days.

“We believe that the reservoir at North Fork is going to do its seasonal flip sometime this week,” Chandler said Monday. “Bee Tree Reservoir did its seasonal flip, we are reasonably certain, last week, which drastically lowered the turbidity there — finally got it under 100 in the lower depths of the Bee Tree reservoir.”

It had stood near 500. 

Bee Tree, located in Swannanoa, is much smaller than North Fork, but the seasonal flip results are encouraging for North Fork, Chandler said, because if the larger reservoir sees a similar shift, it could significantly lower turbidity.

The city announced it was awarding the contract to the Army Corps on Nov. 8. Chandler said the Corps is delivering the filtration system on time, “exactly fitting the timeline that they originally gave us.”

Sex education bill proposed in North Carolina House | North Carolina

(The Center Square) – Directions on curriculum measured age appropriate and access in public libraries to materials considered harmful to minors are in a proposal at the North Carolina House of Representatives.

Parental Rights for Curriculum and Books, also known as House Bill 595, adds to state law a section for age-appropriate instruction for students; a human growth and development program for fourth and fifth graders; and says reproductive health and safety education shall not happen before seventh grade.



Rep. John A. Torbett, R-Gaston




The bill authored by Rep. John Torbett, R-Gaston, and filed Monday additionally has sections on instructional materials and clarification of “defenses for material harmful to minors.” Public library access for minors is in a fourth section.

Gender identity instruction, a buzzword of recent election cycles, is prohibited prior to students entering the fifth grade. The proposal extends that to prior to the entering seventh grade.

The bill would require parental consent to learn about some elements associated with sex education – infections, contraception, assault and human trafficking.

State law allows schools the option to adopt local policies on parental consent for the reproductive health education.

Foxx: Judicial warfare in the flesh causing irreparable damage to America | North Carolina

(The Center Square) – Judicial warfare is eroding the confidence in Americans’ justice system leaving a blight on justice itself, says a North Carolina congresswoman who leads the Rules Committee in the U.S. House of Representatives.

Rep. Virginia Foxx, R-N.C, is speaking out against judges blocking the president’s decisions as granted in the Constitution ahead of a Tuesday congressional hearing.

“As of late, we have certainly seen a slew of rulings by rogue judges that surpass their own constitutional authority,” she said in a post to social media Monday afternoon. “This is judicial warfare in the flesh. If it is not remedied in a commonsense and expeditious fashion, these exercises in partisanship will do further irreparable damage to the nation and to the confidence of Americans in our justice system.”

More than a dozen orders from President Donald Trump – more than in the entire time Joe Biden, Barack Obama and George W. Bush served as presidents – have been thwarted or attempted to be blocked. Among the judges in the spotlight is U.S. District Judge James Boasberg, a pivotal figure in deportation of people accused of being in gangs in addition to just being named to preside in a case involving military operations and a messaging app.

Boasberg, appointed by Bush to the Superior Court of the District of Columbia in 2002, was nominated to the federal bench by Obama and confirmed in the Senate 96-0 in 2012.

Boasberg on Wednesday issued and on Friday extended a temporary restraining order that prevents Trump from using the Alien Enemies Act to deport people believed to be part of the Venezuelan gang Tren de Aragua. A hearing, Judicial Overreach and Constitutional Limits on the Federal Courts, is at 10 a.m. Tuesday to be conducted jointly by the Subcommittee on Courts, Intellectual Property, Artificial Intelligence and the Internet, and the Subcommittee on the Constitution and Limited Government from within the Judiciar Committee of the U.S. House of Representatives.

California Republican Darrell Issa is chairman of the former committee, Texas’ Chip Roy the latter. North Carolina Democrat Deborah Ross is a minority member of the former; North Carolina Republican Mark Harris is a majority member of the latter.

Witnesses scheduled include former House Speaker Newt Gingrich and Cindy Romero, a victim of criminal activity believed perpetrated by Tren de Aragua in Aurora, Colo. Also on the invite list are witnesses from the Edwin Meese III Center for Legal and Judicial Studies at the Heritage Foundation.

Other federal judges drawing fire from supporters of the president include Biden appointees Amir Ali, Loren AliKhan, Deborah Boardman, Angel Kelley and Brendan Hurson; Obama appointees Paul Engelmayer, Amy Berman Jackson, John McConnell and Leo Sorokin; Bush appointee Joseph Laplante; Bill Clinton appointee William Alsup; and Ronald Reagan appointees John Coughenhour and Royce Lamberth.

“Without question,” Foxx said, “exceeding constitutional mandates as a matter of judicial philosophy does nothing more than blight justice itself.”

(The Center Square) – Wildfires continued to burn Monday in the Carolinas, though a sign of optimism arose with a burning ban lifted in 41 South Carolina counties and measured rainfall in both states.

Largest of the fires is Table Rock in Pickens and Greenville counties of South Carolina. The Black Cove fire is burning in North Carolina’s Polk and Henderson counties, the Rattlesnake fire is burning Haywood County, and the Alarka 5 fire is in Swain County.

South Carolina’s Horry County at the Atlantic Ocean and North Carolina border, and the northwestern counties of Spartanburg, Greenville, Pickens and Oconee remain under a burning ban. In North Carolina, all 100 counties have a ban in effect.

The Table Rock fire size is about 13,191 acres in South Carolina and 574 in North Carolina, the Forestry Commission of the former said. Containment is about 30%.

The Persimmon Ridge fire is 2,078 acres in size with 64% containment. Rain Sunday into Monday measured nearly 1 inch.

The Covington Drive Fire in Myrtle Beach is about 85% contained and in mop-up and strengthened firebreaks stage.

In North Carolina, the Black Cove complex of fires are 7,672 acres in size. It includes the Black Cove (3,502 acres, 36% contained), Deep Woods (3,971 acres, 32% contained) and Fish Hook (199 acres, 100% contained) fires. Rainfall overnight into Monday helped the battle.
