However, the report also shows a connection between the shallow aquifer where toxins were found and the deeper Memphis Sand Aquifer that provides the city’s drinking water.
TVA began investigating last year after toxins ended up in wells that monitor pollution from coal ash ponds at its Allen Fossil Plant in Memphis.
The shallow monitoring wells are near far deeper wells drilled directly into the Memphis Sand Aquifer.
The TVA had planned to use the deeper wells to cool a nearby natural gas plant that will replace the coal plant later this year, but it has decided it will not use the cooling wells at this time.
Discovery of the toxins raised concerns from Memphis residents and environmental groups that the contaminants could seep from the shallow Alluvial aquifer where the monitoring wells are located into the deeper Sand Aquifer that supplies the city’s slightly-sweet drinking water.
A layer of clay about 30 to 70 feet thick separates the two aquifers.
Never miss a local story.
The Tennessee Department of Environment and Conservation stated at the time that news of the toxins’ existence was released that the department was confident the contaminants "are not impacting drinking water."
Still, the department asked Memphis Light, Gas & Water — the city’s water utility — to test treated drinking water, and it came up clean.
TVA is planning to buy water from Memphis Light, Gas & Water for daily operations, it said.

THE new vision of our municipality stipulates that by the year 2035, the district municipality will provide adequate access to basic services in an efficient and sustainable manner, enhancing the quality of its citizens in an inclusive progressive economy.
We also deliver services guided by a mission that says that as a water services authority, we will ensure that all our communities have access to quality drinking water, decent sanitation and sustainable economic opportunities underpinned by the active participation of our citizens in exemplary government.
Over the years, our municipality has made remarkable progress in the delivery of water and sanitation services.
However, we cannot stay still at the comfort of these achievements as voices of our communities are still echoing.
Our efforts to expand and improve the access of our services to our communities continue.
It is therefore against this background of our efforts to improve water supply and sanitation services that we have implemented a water supply improvement project for the Qinabout, Thembelihle and Chibini areas in the outskirts of the Gamalakhe area.
This upgrade process commenced in the first week of February and is scheduled to be completed by the end of March.
These communities have been experiencing frequent supply interruptions due to these communities not having formal reticulation.
In the interim, we have put up approximately eight static tanks on different sites for relief supply while work continues to upgrade the pipeline for supply improvement.
We also call for the community’s patience and co-operation while this process unfolds.

Mumbai, Mar 7 The Bombay High Court today reiterated that in times of water scarcity and drought, the priority for water supply would be given to domestic consumption purposes, such as drinking and sanitation, by Maharashtra state.
A bench of Justice A S Oka and RI Chagla said that in cases of conflict over the category that an event or activity must be classified into, the authorities must look at what the dominating purpose of such event was.
"In a case like the present, we have to check what the dominating purpose of the Indian Premiere League (IPL) is.
It is either a sports activity, or a commercial activity and therefore, will rank last on the water supply priority list," the bench said.
"However, the IPL organisers can’t say that since they use this water not just for pitch maintenance but also for the toilets and sanitation in the stadiums, it must get top priority," it said.
The bench was hearing a Public Interest Litigation (PIL) filed by the NGO Loksatta Movement, opposing the IPL matches scheduled in Mumbai and some other cities in Maharashtra in the year 2016, because of the prevailing drought-like situation in Maharashtra at the time.
While the 2016 matches were shifted out of the state following the HC’s order, the PIL had also urged the court to ensure that the provisions of the state as well as the national water policy were adhered to for the IPL matches in the future.
Maharashtra’s own water policy and the national water policy mandates that when it comes to water supply, the first priority must be given to drinking and sanitation purposes, the second to agriculture, third to industrial needs, the fourth to sports, and the last to religious, and recreational activities.
On a previous hearing, the high court had directed the Mumbai Cricket Association (MCA) and the Board of Cricket Control of India (BCCI) to clarify whether the IPL was a sports activity or a recreational activity.
The MCA, meanwhile, has maintained that irrespective of its placement on the water priority list, it will not use potable water either purchased privately, or provided by the civic body, for watering the pitches and for other maintenance work at the Wankhede stadium during this year’s Indian Premiere League matches.

The Huntly mum has had enough of turning on her tap and brown water running out.
* Residents turn noses up at dirty water in Huntly * Discoloured tap water stains clothing "It was almost a reddish black," Wilson said.
Wilson has started buying bottled water for her family to drink because the problem is becoming more frequent.
He’d been flushing pipes that morning along Harris St, Wilson said.
"Council always says the same thing – to flush it for 10 minutes and if it’s no better to call them back."
Council acting waters manager Karl Pavlovich said Wilson’s problem may have been caused by council flushing the pipes.
This is what causes the water to turn brown, he said.
These are random and it is impossible to tell if the flushing will result in the disturbance of settled sediment, Pavlovich said.
However, he admitted neither he or anyone at council would drink the water.
Anyone experiencing brown water can contact council on 0800 492 52.

Shop owners were today accused of cashing in on London’s water crisis by charging up to £8 for bottles of water as 5,000 homes remained without mains supplies.
Several schools in the area also remained shut today, while one emergency water station had apparently have run out of supplies.
A spokesman for Thames Water today said teams were working “flat out” to locate and repair damaged pipes, bleed airlocks and restore pressure in affected areas.
Venting his frustration online, he wrote today: “Day four with no running water in SW16.
“The thing is, their sole purpose is to make money and they’re a one-off.
They feel lied to after all these messages about service coming back.” One shopkeeper said he “wasn’t surprised” by the water bottle price hike, adding: “I’ve had to pay £20 to go in a taxi to pick up bottles front the wholesalers – it sells out so fast.
Thames Water some answers now would be good.” A mother of three from Streatham, Anna, who gave birth last week, told the Standard: “The lack of any communication or accurate information has been appalling.
“The most stressful thing is not being able to do dishes, I had baby screaming at me for milk but [I had] no clean bottles left.” Dunraven primary and secondary school in Streatham was closed for a second day today.
Sunnyhill primary in Streatham also remained closed, while the Livity special school in Streatham was also closed to all pupils, saying: “Thames Water is dealing with water leaks around Streatham and the school has no water.
“Although the situation is recovering we still need to ask for help from the majority of our customers who do have water.

Seventy percent of the Earth’s surface is covered by water — 97 percent saltwater, 3 percent freshwater.
More than a billion people lack easily accessible water.
Meanwhile, Iowa’s relative abundance of freshwater is threatened by inaction, even with legislation passed early in the current session that did little more than provide election cover.
In Iowa, the problem is water quality — runoff primarily from agricultural sources (chemical fertilizers and bacteria from livestock facilities), but also industrial — with potentially dangerous elements spilling into rivers and aquifers.
In December 2017, the state Department of Agriculture and Land Stewardship, Department of Natural Resources and the Iowa State University College of Agriculture and Life Sciences developed the Iowa Nutrient Reduction Strategy.
It estimated a cost of $3 billion to $6 billion to reduce agricultural and industrial pollutants from waterways using thousands of wetlands, hundreds of bioreactors and millions of acres blanketed with cover crops to soak up nitrates.
The other $126 million — tapping an existing tax on metered water currently flowing into the Iowa’s general and school infrastructure funds — will help municipalities and towns improve drinking water and wastewater facilities.
The Iowa Nutrient Reduction Strategy had sought cooperation from the state’s nearly 90,000 farmers, but at a cost of nearly $1.2 billion annually over 50 years.
In 2010, 63 percent of voters approved the Natural Resources and Outdoor Recreation Trust Fund, which would add three-eighths of a cent to the state sales tax, generating $150 million to $180 million annually.
Six years later, 74 percent of Linn County voters approved a $40 million conservation bond to fund projects such as wetlands development to protect sources of drinking water and improve the quality of rivers and streams as well as acquiring land for natural floodwater storage.

TIRUCHY: Students and faculties, staying in hostels and quarters of higher education institutions in Mathur, need not worry about water scarcity problem this summer as Tamil Nadu Water Supply and Drainage Board (TWAD) is making arrangements to bring water from Mukkombu to these campuses through new pipelines.
The management of Bharathidasan University, Anna University and Indian Institute of Management have allotted special funds to lay pipelines from Mukkombu.
The TWAD has laid these pipelines to the three campuses, where the water will be supplied through a combined scheme.
Explaining the project, a senior official with TWAD said, “A water supply channel has been borrowed from the Combined Water Supply Scheme (CWSS) that runs to 1,766 habitats to Pudukkottai district.
The three institutes situated in one zone in Mathur on the city outskirts often face water shortage issue during every summer.
With the unprecedented drought for the past couple of years, the majority of the wells, borewells, canals and water bodies went dry in the region.
BDU Vice-Chancellor P Manisakar told Express, “Our engineers are working on the pipelines, sealing leakages, changing taps to save the excess usage of the water.
The water from TWAD will purvey to all our needs, mainly in students’ hostel.” BDU has 22 borewells, eight wells and three water bodies that have been dried out for the past years.
However, sources in the university claim that the water will not be enough to quench the thirst.
Instead, some of the officials are conducting various studies inside the campus on how to reuse the wastewater for commercial purposes.

The reservoirs have filled sufficiently to allow supply to return however, due to increased demand restrictions will be in place again tonight and for the next few nights until demand regularises and the water treatment plant can meet the demand needs.
It may take several hours for all sections of the network to get water supply.
Customers are being asked to conserve water to avoid reservoirs emptying and water pressure to homes and businesses being affected.
Night time restrictions on the Tully and Letterfrack supplies has enabled the reservoirs to refill to some degree and full supply has been restored this morning.
Irish Water would like to thank customers supplied by these schemes for adhering to our water conservation notice yesterday.
A repair crew travelled to the island this morning (Saturday) to carry out repairs.
Customers on the island are urged to conserve water.
Bottled water is available at Inishbofin pier from 12.30pm.
Williamstown is suffering a major water supply issue and leak repair crews will be undertaking work in the town today to try to restore supply.
The following areas are experiencing low pressure and/or loss of supply due to an increase in demand and some issues at treatment plants: Kilkerrin/Moylough, Mountbellew, Dunmore/Glenamaddy, Ahascragh, Williamstown and Tuam.

LITTLE ROCK — When flooding submerges wellheads, there’s a good chance the well water supply has been contaminated, said Mike Daniels, water quality specialist for the University of Arkansas System Division of Agriculture.
“However, even if flooding has occurred nearby, then it is a good idea to have the water supply tested to assure it is still safe for humans and livestock,” he said.
“If there is any doubt about whether the quality of a water supply has been compromised, it’s important to have that water tested and follow procedures to sanitize the water supply.” You may submit water samples to the state Health Department or the Arkansas Water Quality Lab.
Visit arkansas-water-center.uark.edu/water-quality-lab.php to learn how to collect a sample to get an accurate result.
“It’s best to submit the sample within 24 hours after collection,” Daniels said.
However, “as long as the sample has been refrigerated, it will be about to provide realistic results for up to four days.” If the results show more than 10,000 colony forming units of total bacteria per milliliter, more than 100 colony forming units of coliform bacteria, or more than 50 colony forming units per milliliter, it’s a good idea to shock chlorinate the well.
Shock chlorination is a process by which home water systems, such as wells, springs and cisterns are disinfected using liquid bleach, or chlorine.
“It is the most widely recommended means of treating bacterial contamination in home water system as it is the quickest, cheapest and most efficient method of treatment,” Daniels said.
“Shock chlorination should only be done when the water supply will not be used by humans or animals for at least 24 hours because the initial chlorine levels are not safe to drink.” Visit uaex.edu/publications/pdf/MP292.pdf to learn more about shock chlorination in MP292 and improving home water quality.

DAYTON, Ohio (WDTN) – Following Wednesday’s Dayton City Commission meeting, the city manager praised Wright Patterson’s response to prevent drinking water contamination from previous firefighting activity on the base.
“We’re very pleased to see Colonel McDonald’s response with regards to they share our sense of urgency.
They do have some plans moving forward,” said City Manager Shelley Dickstein.
In part, Col. McDonald said, “The Air Force is committed to protecting human health and the environment and we are working aggressively to ensure our installation and surrounding communities have access to safe drinking water.” In 2015, inspectors found traces of toxic chemicals linked to foam previously used as a firefighting technique on the base.
As a precaution to prevent contamination into groundwater through the nearby Huffman Dam, the city shut down seven underground wells.
The base detailed its ongoing inspections and efforts to replace any remaining extinguishers and response vehicles using AFFF.
Col. McDonald also said the Air Force is planning a more thorough inspection this summer to determine whether more actions are necessary.
“We know well in advance if there’s some issue,” Dickstein said.
