With turbidity at North Fork Reservoir barely budging in recent days, the City of Asheville continues to deliver discolored, non-potable water to customers, and announced Wednesday it has amped up its testing program.

Several water customers have reached out to Asheville Watchdog to express concerns about the water quality and whether it is safe for showering. A Water Resources spokesperson assured residents that the water is safe for non-consumption uses.

The entire city water system remains under a boil water notice, and the city has stressed that the heavily chlorinated but unfiltered water it’s distributing from North Fork Reservoir is meant only for flushing commodes, taking showers and other non-potable uses. Customers should use bottled water for drinking water.

Water Resources Department spokesperson Clay Chandler spent most of his time at the daily Helene briefing on Wednesday talking about the water testing program, but he said afterward it does not come in response to customer complaints.

“We certainly don’t underestimate customer concerns, but the testing plan on the website was formulated by us and approved by our regulators before we started moving water from North Fork,” Chandler said. “It’s definitely fair to say that we’ve leaned into making it accessible as possible in response to questions and concerns from customers.”

Chandler said the department conducts daily testing throughout the distribution system for total coliform, E. coli and chlorine “to ensure the safety of our customers.” Coliform is a bacteria commonly found in the environment and the intestines of humans and mammals, E. coli is a bacteria that can cause serious intestinal infections, and chlorine is a chemical used as a disinfectant in municipal water systems. There has been no evidence of E. coli, Chandler said, and chlorine levels remain high.

The water department, with guidance from the EPA and the North Carolina Department of Environmental Quality, “developed and implemented a sampling plan specific to recovering from Helene,” he said. 

In all, Water Resources has 184 sampling stations throughout the system, and under normal conditions it runs tests on eight to 10 per day. While some chemicals have tested higher than recommended amounts, the levels are not significant, Chandler said.

“Since Helene, we have tested an average of 35 stations per day, and we hope to get that up to 40,” Chandler said, adding that testing is “slightly more accurate when the water is clear. And again, the water at North Fork, as everybody knows by now, is extremely turbid.”

Turbidity is measured in Nephelometric Turbidity Units, or NTUs, and the EPA requires filter water to be less than .30 NTU for consumption. At North Fork, normal filtered water is between .03 and .05 NTU, but since the storm it’s remained stubbornly high, including Wednesday when it measured 26, according to Chandler. 

It was nearly the same level Monday, and it stood at 30 on Oct. 11.

Clarity of the reservoir, which was stirred up and then inundated by clay-laden floodwaters on Sept. 27, is key to once again providing the system’s 63,000 users with potable water.

“The target that we have now is 1.5 NTUs, which, while it’s a little bit higher than what we normally see, is still much lower than if you were to average water systems across the United States,” Chandler said. 

North Fork serves about 80 percent of the city’s water customers, and the city has already conducted one mineral treatment program designed to help with turbidity — an infusion of aluminum sulfate and caustic soda — but it has not been very effective, in part because of high winds the two days the chemicals were administered.

“Since we’re under some pretty extraordinary circumstances, we have decided to go ahead and test daily for aluminum, iron and manganese, because we know those can be elements of concern,” Chandler said.

While these minerals do cause discoloration and cloudiness in the water, they are generally safe in low levels.

“It’s certainly accurate to say that low levels of aluminum, iron and manganese are naturally occurring in water supplies and do not pose significant health hazards at those levels,” Chandler said after the briefing.

Typically, elevated levels of these substances are “extremely rare under normal circumstances,” he said. 

North Fork’s filters are made for clear water, as that’s what the reservoir’s heavily forested 20,000-acre watershed generally provides. The city will conduct another mineral treatment next week, and it plans to install a three-layer “curtain” system next week that should help improve water clarity.

Earlier in the week, Chandler said portable filtration systems exist, but North Fork pumps out more than 20 million gallons of water daily, a level of production those units can’t handle.

“That does not mean that we have given up on that,” Chandler said. “The Army Corps of Engineers is putting pencil back to paper to see if they can come up with some solutions that can meet the 20 million gallons per day capacity that we have to meet.”

“If I sort of implied that that part of it had been given up on, that is absolutely not the case,” Chandler continued. “Water Resources, our partners at EPA, and the Army Corps of Engineers are working literally around the clock to come up with something.”

Chlorine levels are high

The federal government has set secondary “Maximum Contaminant Limits,” or MCLs for drinking water. Normally, the city water has a chlorine level of four parts per million.

“But after Helene, both the EPA and North Carolina DEQ allowed us to chlorinate initially at eight parts per million, because that was the only thing that we could add to the water,” Chandler said. “Remember, we’re not using our normal treatment and filtration systems. We’re sending water straight out of the lake and hyper-chlorinating it.”

The city has since dropped that level to six parts per million. 

“It’s a very good sign, because that means as we test for chlorine throughout the distribution system, chlorine levels are remaining high, because there are very few pathogens in the distribution system that’s eating it up,” Chandler said. “So if chlorine remains high throughout the distribution system, that’s a very positive sign.”

Since Helene, the city has had no detections of E. coli.

“We are not allowed a single positive (test result) here for E. coli, because that would automatically trigger a boil water (notice),” Chandler said. “And to be clear, that is not the reason we issued the boil water notice that we’re under now. We issued that boil water notice because of the sediment that’s in the water.”

Customers have likely noticed the water in their homes or businesses being cloudy and brown in some places, Chandler said. “That is why we are under this current boil water notice, not an E. coli positive hit.”

Discoloration mostly an aesthetic issue

The discolored water is mostly an aesthetic issue, although the water is not drinkable. Chandler acknowledged that, “Obviously, clear water is more appealing. Cloudy water is not.” 

But he noted that federal and state regulators do not enforce recommendations on water aesthetics.

“For example, the levels of iron and manganese in the unfiltered water that we’ve sent through our distribution system have slightly exceeded the MCLs, and our regulators are completely aware of that,” Chandler said. “They’re at North Fork every day. They’re in City Hall, in our offices, every day.”

The practical effect of the discolored water is that “those with medical conditions who might be susceptible to increased levels of aluminum or manganese, should simply consult with their doctor,” Chandler said.

Aluminum produces a cloudy look to the water, Chandler said, while the rusty look comes from iron, which also leaves a metallic taste and causes a reddish-brown staining on toilets.

Manganese, which is black to brown in color, “causes a metallic taste in the water and produces yellow staining on toilets and other appliances,” Chandler said.

“It is also very important to note that the in-reservoir treatment process that we concluded last week and that we will restart next week, it will actually work to reduce levels of iron and manganese in the water,” he said.

Aluminum sulfate is a “salt-ish” mineral the department uses to regularly treat the reservoir, as it makes clay particles coagulate and sink, leading to clearer water for filtering and treatment. Caustic soda helps with optimum pH levels for the coagulation to work best.

Chandler said it’s important to note the city has “not exceeded the MCL as far as aluminum yet.

“We know that level is going to go up next week when we start the second round of the in-reservoir treatment process, and so that’s why we’re rolling out these real time test results today,” he said.

Chandler also noted that with school restarting next week, the city has tested water for lead at every city school, with the exception of Hall Fletcher Elementary, which is in the process of switching from city water to a newly installed well. That testing will take seven to 10 business days.

The city has a lengthy FAQ section on its water recovery page, and it contains information about the testing program.

With the beginning of early voting across North Carolina last Thursday we are now in the political equivalent of a baseball game’s early innings or in football’s first quarter. Although teams may be putting points on the board, much can happen before the close of counting on Election Day, Nov. 5.

But while those numbers don’t tell us everything, they may tell us something. In my judgment, there are a few key numbers to know and to follow as we approach the finish, as they may be the measures of victory or defeat. (Note the emphasis on the word “may,” which translates into “take with grain of salt.”) 

Most crucial among these numbers is 74,483. Expressed in a different way, this number is 1.34 percent. To which you likely respond: What are you talking about?  

Donald Trump, in his 2020 loss to Joe Biden, carried North Carolina by that number of votes. His victory margin was 1.34 percent – the smallest margin of the 25 states he won.  

Of course many things have changed since then that may affect that number. The state’s population has grown and become younger and more urban. The party registration numbers have shifted from Democrats and Republicans and toward independents. Kamala Harris isn’t Joe Biden. Trump was impeached a second time after his involvement in the January 6, 2021, insurrection, and he awaits sentencing after being convicted of 34 felonies. 

Still, as consequential as each of those factors would typically be, every credible poll taken since Biden stepped aside and endorsed Harris has found the race to be a dead heat. It’s about where things stood on Election Day 2020.

That suggests the key to handicapping the outcome this year is to find clues in the latest numbers that the ex-president, despite his many legal issues, is hanging on, or that Harris has bridged the gap and can flip the outcome her way. 

Here’s one of those key clues: Last Thursday, the first day of early voting, 5,607 more people cast ballots across the state than did so in 2020, which itself was a record. That one day itself represents a 1.3 percent jump. In addition, a record 75,133 absentee ballots were accepted (although they won’t be counted until voting ends Nov. 5). 

Of course we can’t know for which candidate those ballots were cast. But we do know that more registered Democrats voted that day than registered Republicans, according to state Board of Elections data, which may be a measure of enthusiasm by party loyalists. And notably, more Democrats voted than registered independents (officially called unaffiliated voters), which is by far the largest voting bloc.

Not surprisingly in blue Buncombe County, three Democrats turned out on the first day for every Republican. The Democrats had a slimmer 6-5 edge over the unaffiliated, whose leanings are less predictable. 

The opening-day trend has continued through Monday, with registered Democrats out-voting registered Republicans and the unaffiliated, though by fractions of a percentage point.    

In sports terms, this means only that the Democrats may have taken a slender lead in the early minutes of the game. We also know from recent elections that Democrats like to vote early while Republicans tend to vote more heavily on Election Day, though this may be changing. As I said, take these numbers with salt. 

I’ll leave you with one interesting, though irrelevant statistic: Oddsmakers in NFL games have found that the team with a lead after the first quarter wins 65.75 percent of the time.

Your vote can ensure that nothing will get done

I have been asked by some Asheville Watchdog readers to explain the purpose of a proposed amendment to the North Carolina Constitution appearing to make it illegal for foreigners to cast ballots here. What puzzles these readers is the fact that it is already illegal for non-citizens to vote in our elections. In fact, it’s a felony. And every voter acknowledges this when signing their ballot-authorization paper.  

It brings to mind a nursery rhyme that begins like this: Yesterday upon the stair I met a man who wasn’t there. He wasn’t there again today. I wish, I wish he’d go away.

This proposed amendment is the state House Republicans’ version of that invisible man upon the stair. Because of their efforts, that man still isn’t there. The original ditty by Hughes Mearns was meant to rid children of their belief in boogeymen under the bed who, of course, weren’t there and continued not being there night after night.

In this case, led by departing House Speaker Tim Moore who needed an issue to boost his election to Congress, the invisible boogeymen are anti-GOP foreigners who sneak into the country to cast ballots to sway elections (apparently favoring Democrats).

There is no evidence of this happening. But Moore felt the need to demonize immigrants – including naturalized citizens – so some may stay home on Election Day. Moore’s GOP friends in Raleigh humored him by drafting this constitutional amendment to amend the existing one and ensure that nothing will result that isn’t already not being done.

Here is the current law: “Every person born in the United States and every person who has been naturalized” shall be entitled to vote. And here is the proposed amendment to the law: “[O]nly a citizen of the United States…” shall be entitled to vote.

Do you see the difference and now understand why the GOP believes the new amendment is needed? Of course you don’t. So why would House Republicans take the rare step of putting this measure before voters? 

Because this is a year in which immigrant fear-mongering runs through the GOP in both the state Assembly and in Congress.  

So what are voters to do when they get to this ballot question? They can vote no, in which case nothing will change. Or they can vote yes, and nothing still won’t change. Or they can skip the line and be sure that nothing will change.  

And we can all wish that this partisan nonsense will go away.

Helene, Asheville and Project 2025

Among the crucial federal agencies severely disrupted by Tropical Storm Helene is the National Climatic Data Center, which is headquartered in Asheville. This is the government operation that maintains the world’s largest archive of meteorological and climatological data on Earth. Among its achievements: The scientific evidence of global warming was collected and reported by the NCDC, based on the Asheville archive.

Despite its scientific importance, the pro-Trump Project 2025 proposes to break up the National Oceanic Atmospheric Administration (NCDC’s parent), sell its weather-forecasting functions to commercial operators, and smother its Asheville-based climate-change reporting. Project 2025 is the right-wing Heritage Foundation’s blueprint for the next Trump administration should he win the election.

Project 2025 characterizes the agency as the power behind the “climate change alarm industry.” But Mother Nature apparently got a head start on this plan by directing Helene (according to Marjorie Taylor Greene) to slam into the NCDC’s digitized operations center in downtown Asheville, putting access to its archive off line for several days.
