Can You Drink Tap Water in Durham?

Yes, Durham's tap water is generally considered safe to drink as Durham has no active health based violations of the Safe Drinking Water Act (SDWA) that we are aware of. Other factors such as lead piping in a home, or low levels of pollutants on immunocompromised individuals, should also be considered, however. To find more recent info we might have, you can check out our boil water notice page or the city's water provider website.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Durham's water utility, City of Durham, had 2 non-health-based violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. The last violation for Durham was resolved on June 30, 2018. This assessment is based on the City of Durham water system, other water systems in the city may have different results.

While tap water that meets the EPA health guidelines generally won’t make you sick to your stomach, it can still contain regulated and unregulated contaminants present in trace amounts that could potentially cause health issues over the long-run. These trace contaminants may also impact immunocompromised and vulnerable individuals.

The EPA is reviewing if it’s current regulations around pollutant levels in tap water are strict enough, and the health dangers posed by unregulated pollutants, like PFAS.

Water Quality Report for Durham Tap Water

The most recent publicly available numbers for measured contaminant levels in Durham tap water are in its 2020 Water Quality Report. As you can see, there are levels which the EPA considers to be acceptable, but being below the maximum allowable level doesn’t necessarily mean the water is healthy.

Lead in tap water, for example, is currently allowed at up to 15ppb by the EPA, but it has set the ideal goal for lead at zero. This highlights how meeting EPA standards doesn’t necessarily mean local tap water is healthy.

EPA regulations continue to change as it evaluates the long term impacts of chemicals and updates drinking water acceptable levels. The rules around arsenic, as well as, lead and copper are currently being re-evaluated.

There are also a number of "emerging" contaminants that are not currently. For example, PFAS (Per- and polyfluoroalkyl substances), for which the EPA has issued a health advisory. PFAS are called "forever chemicals" since they tend not to break down in the environment or the human body and can accumulate over time.

We recommend looking at the contaminants present in Durham's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

Durham Tap Water Safe Drinking Water Act Violation History - Prior 10 Years

Below is a ten year history of violations for the water system named City of Durham for Durham in North Carolina. For more details please see the "What do these Violations Mean?" section below.

For the compliance period beginning July 1, 2021, Durham had 1 non-health based Safe Drinking Water Act violation with the violation category being Other Violation, more specifically, the violation code was Consumer Confidence Report Complete Failure to Report which falls into the Other rule code group, and the Consumer Confidence Rule rule code family for the following contaminant code: Consumer Confidence Rule.

For the compliance period beginning July 1, 2020, Durham had 1 non-health based Safe Drinking Water Act violation with the violation category being Other Violation, more specifically, the violation code was Consumer Confidence Report Complete Failure to Report which falls into the Other rule code group, and the Consumer Confidence Rule rule code family for the following contaminant code: Consumer Confidence Rule.

From June 1, 2018 to June 30, 2018, Durham had 1 non-health based Safe Drinking Water Act violation with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring, Turbidity (Enhanced SWTR) which falls into the Microbials rule code group, and the Surface Water Treatment Rules rule code family for the following contaminant code: Interim Enhanced Surface Water Treatment Rule.

From Sept. 1, 2015 to Sept. 30, 2015, Durham had 1 non-health based Safe Drinking Water Act violation with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring, Repeat Minor (TCR) which falls into the Microbials rule code group, and the Total Coliform Rules rule code family for the following contaminant code: Coliform (TCR).

Is there Lead in Durham Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Durham water system, City of Durham, between sample start date and sample end date, were at or below, 0.0 mg/L of lead in Durham water. This is 0% of the 0.015 mg/L action level. This means 10% of the samples taken from Durham contained more lead.

While Durham water testing may have found 0.0 mg/L of lead in its water, that does not mean your water source has the same amount. The amount of lead in water in a city can vary greatly from neighborhood to neighborhood, or even building to building. Many buildings, particularly older ones, have lead pipes or service lines which can be a source of contamination. To find out if your home has lead, we recommend getting you water tested.

No amount of lead in water is healthy, only less dangerous. As lead accumulates in our bodies over time, even exposure to relatively small amounts can have negative health effects. For more information, please check out our Lead FAQ page.

Are there PFAS in Durham Tap Water?

Currently, testing tap water for PFAS isn’t mandated on a national level. We do have a list of military bases where there have been suspected or confirmed leaks. There appears to be at least one military base - Morrisville AASF #1 - near Durham with suspected leaks.

With many potential sources of PFAS in tap water across the US, the best information we currently have about which cities have PFAS in their water is this ewg map, which you can check to see if Durham has been evaluated for yet.

Our stance is better safe than sorry, and that it makes sense to try to purify the tap water just in case.

What do these Violations Mean?

Safe Drinking Water Act Violations categories split into two groups, health based, and non-health based. Generally, health based violations are more serious, though non-health based violations can also be cause for concern.

Health Based Violations

  1. Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
  2. Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
  3. Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.

Non-Health Based Violations

  1. Monitoring and reporting violations (MR, MON) - failure to conduct the required regular monitoring of drinking water quality, and/or to submit monitoring results on time.
  2. Public notice violations (Other) - failure to immediately alert consumers if there is a serious problem with their drinking water that may pose a risk to public health.
  3. Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

DEDICATED TO

SERVICE

2020. What a year! Durham and the Department of Water Management (DWM) faced a number of challenges during the year. Along with the rest of the world, the COVID-19 pandemic created serious issues for the City and DWM. Some departmental services were modified or reduced as some staff were sent home to work or placed on rotating schedules designed to minimize contact and risk of exposure. Non-critical services were suspended, and other routine tasks were rescheduled. While vaccinations are now available and infections are declining, the battle is not over.

In early March 2020, the City of Durham became a victim of a malware attack that affected the City’s computer systems. Fortunately, our water treatment facilities and delivery systems were not impaired by the malware attack and we continued to provide safe drinking water to our customers, 24/7/365.

And when you turned on your tap, we delivered!

We delivered safe drinking water to hospitals and other medical facilities so that they could treat critically ill patients. And with residents working – and in many cases teaching – from home, delivery of safe water was increasingly important.

Despite these challenges, Durham’s water quality was not impacted. There were zero water quality violations in 2020.

We also completed several major capital projects in 2020. The Brown and Williams water treatment plants expansion and upgrades were mostly finished. And in September, our Laboratory Services and Industrial Waste Control teams moved into the Compliance Services Building. Learn more about the LEED-Silver home of our state-certified water and wastewater lab on page 8.

Our Water Efficiency team continued to provide virtual water use assessments while also winning their fifth consecutive national EPA WaterSense® Award for Excellence in Education and Outreach.

While most of us want to put 2020 in our collective rearview mirrors, the events of 2020 reinforced what I already knew – we have a resilient and remarkable staff. As you read this report, keep in mind that City of Durham Department of Water Management employees are here for you – dedicated

to service.

MANAGING DURHAM’S DRINKING WATER

WHERE IT COMES FROM. HOW IT’S TREATED.

Drinking water – both tap and bottled

  • comes from rivers, lakes, streams, ponds, reservoirs, springs, and wells.

As this water travels over land or through the ground, minerals and other materials naturally dissolve into it. As it moves through our environment, water can also pick up substances that are the result of animal or human activity.

Source water may contain:

  • Microbial contaminants, such as viruses and bacteria.
  • Inorganic contaminants, such as salts and metals.
  • Pesticides and herbicides from agriculture or urban run-off.
  • Organic chemicals from industrial processes or run-off.
  • Radioactive contaminants that can occur naturally.

The EPA regulates the amount of certain substances in your tap water. This is to ensure that tap water is safe to drink.

The U.S. Food and Drug Administration establishes limits for contaminants in bottled water to protect public health.

Four Sources Ensure Reliable Drinking Water

Durham residents and businesses use, on average, about 25.9 million gallons of water a day (MGD). We’re fortunate to have two high-quality surface water sources to meet that demand: Lake Michie, built in 1926, and Little River Reservoir, built in 1988.

City tap water:

  • Meets all federal and state quality standards
  • Reduces environmental impact (no discarded plastic bottles)
  • Saves you money

CITY OF DURHAM 2020 WATER QUALITY REPORT | 2

A lab coordinator at work in the new Compliance Services Building

City water managers use modelling to determine the amount of water that can be taken from the two lakes. Accounting for the extreme drought conditions of 2007-2008 and a 20% safety factor, these two sources safely yield 27.9 MGD. Plans are being developed to tap two additional water sources – Jordan Lake and Teer Quarry – to meet demand now and in the future.

Jordan Lake has provided as-needed water for the City via the Town of Cary’s water system since 2002, when we obtained an allocation of approximately 10 MGD. Following the drought of 2007-2008, the City pursued an additional 6.5 MGD allocation to meet projected water demand through 2060. The N.C. Environmental Management Commission granted the request in 2017. The City is collaborating with neighboring water agencies to bring water directly from Jordan Lake into our system.

Teer Quarry first provided emergency supplemental water for the City during the height of the drought in 2007-2008. The City purchased the abandoned quarry in 2004 and is in the planning stage to build permanent facilities that will allow the quarry to refill from a number of sources during high flow conditions and provide a reliable emergency water source.

Two Treatment Plants Provide Clean, Safe Drinking Water

Water moves from Durham’s two supply lakes to its two City treatment plants – Williams and Brown – by gravity flow, hydropower, and electric power. On-site reservoirs at each plant hold a two- to three-day supply of water that helps even out the pumping strategy.

In 2020, Durham’s two plants provided 25.9 MGD of water to more than 301,000 customers. Williams Water Treatment Plant on Hillandale Road, completed in 1917, has been upgraded a number of times and has a capacity of 22 MGD. Brown Water Treatment Plant on Infinity Road, completed in 1977, has a capacity of 42 MGD. Major renovations begun in 2017 were contractually completed in early 2021.

Both plants use conventional water treatment processes. The initial treatment step is coagulation, which involves the rapid mixing of caustic and ferric sulfate into the untreated source water. Next, the water flows into chambers, where gentle mixing allows dirt and other impurities to stick together, or flocculate. Heavy floc particles are formed, settle, and are removed in sedimentation basins. Chlorine is added to the settled water as a disinfectant. The water then flows through

sand and anthracite filters to remove any remaining particles. Phosphate (which keeps pipes from corroding) and fluoride (for dental health) are then added. In the final step, chloramines are added as a disinfectant.

The City of Durham has added fluoride to its drinking water since 1957 to promote dental health. Until recently, state regulations required a target concentration of 1.0 mg/l for fluoride. However, in 2011, the U.S. Environmental Protection Agency (EPA) and Centers for Disease Control determined that dental health could be maintained with lower levels of fluoride. Based on this, N.C. regulators have allowed water systems to decrease their fluoride target levels to 0.7 mg/l. The City changed dosage levels for fluoride immediately upon receiving approval. Testimony from public health experts supports the continued addition of fluoride to drinking water as an ongoing safeguard for dental health.

2020 WATER QUALITY TESTING RESULTS

REGULATED CONTAMINANTS TESTING: 100% COMPLIANCE

The City (Public Water System ID # 03-32-010) routinely monitors more than 150 contaminants in your drinking water, in accordance with federal and state laws. In 2020, the City performed 30,181 tests on Durham’s drinking water. The table below lists all the regulated drinking water contaminants that were detected during testing conducted from January 1 to December 31, 2020. It shows that all substances were found to be at least 30% below the regulatory threshold in 2020. Note: EPA and the state require water providers to monitor for certain contaminants less than once per year because the concentrations of those contaminants are not expected to vary significantly from year to year. Thus, some of the data, while representative of water quality, is more than one year old.

PROTECTING YOUR WATER FROM CONTAMINANTS

What EPA Wants You to Know About Water and Contaminants

Drinking water, including bottled water, can be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily mean that the water could be a health risk. Get more information about contaminants and potential health effects by calling the EPA’s Safe Drinking Water Hotline at (800) 426-4791.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno- compromised people, such as those with cancer undergoing chemotherapy, people who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly people, and infants, can be particularly at

risk for infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on the best ways to reduce the risk of infection by Cryptosporidium and other microbial organisms are available from the Safe Drinking Water Hotline at (800) 426-4791.

No Cryptosporidium in Durham’s

Drinking Water

Cryptosporidium (Crypto), a microbial parasite that comes from animal waste, occurs naturally in rivers and lakes but can cause fever, diarrhea, and other gastrointestinal symptoms when swallowed.

Controlling and minimizing development and animal activities in our watershed reduces the occurrence of Crypto in source water. The water treatment process of filtration, sedimentation, and disinfection typically removes it.

The City began monthly testing for Crypto in fall 2006 (as per Long Term Two Enhanced Surface Water Treatment Rule, LT2SWTR) and has never found the parasite in any monitoring event.

What the City Wants You to Know About Lead and Drinking Water

There is no detectable lead in drinking water leaving Durham’s two water treatment plants. We have an ongoing program to replace our older water mains and we add a corrosion inhibitor to the drinking water. We also diligently monitor water quality to ensure appropriate levels of corrosion inhibitor are maintained.

Elevated levels of lead can cause serious health problems, especially for pregnant women and young children.

Lead enters drinking water primarily due to the corrosion of materials containing lead used in older household plumbing and service lines that are not managed carefully.

Any resident with concerns about lead in their drinking water can have their water tested and can take steps to minimize exposure, such as flushing tap water for 30 seconds to two minutes before using it for drinking or cooking. Call Durham One Call at (919) 560-1200 to request a water sample testing kit.

PFAS: What You Should Know

PFAS has been a hot topic in the news, both nationally and here in North Carolina. What are PFAS? Per-and polyfluoroalkyl substances are a group of more than 4,000 man-made chemicals that have been used in manufacturing since the 1930s. You can find them in shampoo, paint, fast-food packaging, stain repellent, nonstick cookware, and firefighting foam. They’re slow to break down, which is why some experts call them “forever” chemicals. They can be found in surface water, groundwater, and in the air.

Water Management staff take PFAS very seriously and have been carefully tracking national and state research on them. Since 2018, we have tested for these substances in both of our source waters - Lake Michie and Little River Reservoir - and our tap water. Of the 39 different PFAS compounds tested, we have detected only very low concentrations (single parts per trillion) in our water supply.

Currently, there is no adopted federal standard set for these chemicals, however EPA announced a health advisory goal of 70 parts per trillion (ppt) for the combined levels of the two PFAS compounds most commonly found in the environment - PFOS and PFOA. Our testing has measured these compounds in our drinking water in the range of 6.4 to 12.7 ppt. This is from five to ten times lower than the 2016 EPA health advisory goal.

Assessing Water Source Vulnerability

The N.C. Department of Environmental Quality (DEQ) Public Water Supply Section, through its Source Water Assessment Program (SWAP), periodically assesses all drinking water sources in the state — wells and surface water intakes — to determine their susceptibility to potential contaminant sources (PCS).

PCSs include animal operations, septage disposal sites, old landfill sites, underground storage tanks, and activities that could negatively impact water sources in Durham, Person, and Orange counties — the watersheds of Lake Michie and Little River Reservoir. The susceptibility rating is determined by combining a “Contaminant Rating,” which is based on the number and locations of PCSs within the testing area, and “Inherent Vulnerability Rating,” based on geologic, surface water, and watershed features and conditions.

A susceptibility rating of “higher” indicates the system’s potential to become contaminated by PCSs in the tested area, not the quality of the water. These findings help water managers identify areas and activities that may require monitoring or action.

The table below shows the latest assessment results.

IMPROVING YOUR

WATER SYSTEM

In 2020, Water Management closed out multi-year capital construction projects that included updating the Williams and Brown water treatment plants. We also constructed a new home for the department’s state-certified water and wastewater Lab and the Industrial Waste Control divisions.

Both had had been housed in the South Durham Wastewater Reclamation Facility since the late 1980s. In 2010, it became clear that the HVAC equipment couldn’t keep up with the demands of sophisticated laboratory equipment, and periodic basement workspace flooding created challenges for staff. These issues and the need for increased sample security compelled the department to explore options.

The solution was the construction of a new Compliance Services Building (pictured) on adjacent City property. It features public areas with a training room and administrative offices and secure areas for staff offices and laboratory testing areas, which require security credentials for access. A separate entry allows lab staff to receive and process samples from water and wastewater sites and internal customers submitting distribution samples. The lab and work spaces were designed to accommodate expansion.

The new building features geothermal wells for heating and cooling, reclaimed water for toilet flushing, and drought tolerant landscaping. Windows and skylights brighten work spaces and reduce energy costs. These features enabled the building to qualify for Silver LEED certification. LEED (Leadership in Energy and Environmental Design) is a green building rating program of the U.S. Green Building Council that works to transform how buildings are designed, constructed, and operated to improve sustainability.

CONSERVING OUR WATER RESOURCES

Ensuring that Durham’s water supplies are sufficient well into the future is a top priority, and the City takes specific steps to empower residents to make wise water use decisions to extend the life of our water supplies.

Our Water Efficiency Program focuses on working with water customers to reduce water demand and maximize efficiency. The Department of Water Management continues to be a proud EPA WaterSense® Partner, and in 2020, Durham was once again recognized by the EPA for our commitment to protecting the environment through water efficiency and was awarded a WaterSense Excellence Award — our fifth consecutive national award.

Customer awareness, adoption of water efficient fixtures and devices, and programmatic incentives all play a part in inspiring water efficiency. Two popular initiatives that help our customers to improve their water efficiency are:

  • Toilet Rebate Program - Toilets, on average, still account for nearly a quarter of the total water used in homes. Standard toilets use at least 1.6 gallons per flush. WaterSense labeled toilets use at least 20% less than standard ones and can save the average family approximately 13,000 gallons of water every year. Residential customers can receive rebates up to $100 for each standard toilet they replace with a WaterSense toilet.
  • Save Water Kits - Customers can pick up our Save Water Kits for $3 from the Cashiering counter at City Hall and receive WaterSense
    showerheads, faucet aerators for the kitchen and bath, and other useful items.

Durham Safe Water

The question of if is Durham water is safe to drink has been at the forefront of much controversy. Since Raleigh recently experienced a large sewage outbreak that contaminated the city’s drinking water, it has become a serious topic. Many people are wondering if the water they are drinking is safe to drink and how they should react to the situation. There have also been questions as to what role the government should play in helping clean up the mess left behind by the sewage spill. Those who live in the area have been calling for different solutions to clean up the mess and make the area safer for everyone. One solution that is being used is using water purification devices.

These devices were actually invented in Durham during the industrial Revolution. In those days, factories dotted the area and most of them had no running water whatsoever. Manufacturers came up with a solution to this problem by developing the first public water purification system in the United States. They needed something that could clean the water and remove all of the dangerous elements that were in the water. With the invention of the chlorination process, they were able to create what we know today as the public water treatment system.

If you are concerned about the water that you are drinking, then you should consider getting a purification system. You will not only be doing your part to help the environment, but you will also be making yourself and your family healthier. The amount of contaminants that can be found in the water supply is disturbing. For every gallon of water that you are consuming, 10 pounds of toxic chemicals end up in the groundwater. This is why it is so important that you have a purification system installed in your home. Once you have one, you can stop worrying about what is in your water and start focusing on making the world a better place.

Durham Drinking Water

Have you ever driven through Durham, North Carolina, and wondered where the drinking water came from? If so, it may interest you to know that the Duke University Center for Environmental Assessment has recently conducted a study showing where the tap water comes from in Durham. This is not your typical tap water study, because they use state-of-the-art instruments to detect contaminants, including heavy metals like lead and aluminum. They found more than two hundred different contaminants in the drinking water of Durham.

This is a surprising finding and one that Duke University welcomes. “We know that people living in the Triangle area have a higher concentration of some contaminants than people living elsewhere in the United States. The reason is that the chemicals that are most commonly found in runoff from the southern parts of the Triangle River basin Leach into the local rivers, streams, and lakes, and then into the groundwater supply of the area. ” There are many reasons why the waters of Durham are considered to be unhealthy, but no one yet knows why or how they are entering the drinking water.

This study may be good news, however. It means that more attention is being paid to preserving the environment and protecting public health. Most people realize that they need to stop washing their hands before drinking, but they don’t realize that they need to protect the clean water supply that we all have from contamination. Most cities and counties have limits on the amount of water that can be used or released for drinking, but those guidelines don’t apply to the groundwater supply. You need to make sure that you have access to clean water at all times if you want to stay healthy and safe.

Durham Water Treatment

If you are looking for water purification in Durham, North Carolina, there are a variety of options available to you. This area has one of the best public water treatment systems in the country, so you can relax knowing that your water is safe and clean. The city of Durham was named after an American Revolutionary War hero and engineer who served time in prison for his role in fighting in the war. Today, he is also the county’s largest planner.

There are several treatment centers around the city. One of them is located at Durham Medical Center in the heart of downtown Durham. Here, you can get a free health examination and have your blood tested for diseases. Once you have received a clean bill of health, you can fill out an online application for a drinking water filter system and start enjoying the amazing benefits of water purification. You can save money by choosing a system that gives you both filters for your faucet and pitcher, so you can take advantage of both in one unit.

Another water treatment center is at Hodge Associates in Raleigh. This facility serves all of the areas of Durham including its downtown area. Here, you will find a large water treatment facility that serves all of the city’s public water lines. The Hodge Center is also North Carolina’s first certified solar water heater, so you can also feel environmentally friendly while enjoying your tap water.

Durham Water Contaminants

The Durham government recently announced that they have been testing thousands of homes for possible contaminants and will be releasing the information soon. They found that more than two hundred different contaminants were found in the city’s water supply. These range from naturally occurring things like arsenic and copper to chemicals used in industrial processes. Many people are concerned about this because they believe that the levels of these toxins are too high to be safe for human consumption.

There are many homes across the county that use the Durham municipal water supply. The Triangle is the area that has been affected the most because so many homes there have such high levels of toxins and contaminants in them. Many people have had to move their homes because they cannot afford to pay the amounts of money it costs to treat the water on a continuous basis.

There are some people who live in the rural areas that do not use the city’s water supply and still suffer from horrible health problems. The reason for this is because they consume such large amounts of water on a daily basis. This is not helpful to them at all, and they need to find something that can help them to detoxify their bodies. It is unknown if the toxins found in the water were contained before the city began testing the water, or if it was discovered during an investigation. Either way, the results are alarming and everyone needs to do something to clean up the contaminated water.

Durham Water Quality

Durham is the tenth-largest city in the state of North Carolina and is a beautiful place to live. Durham is also the county seat of Wake County and is located on the eastern shore of the Raleigh Channel. In terms of both population and area, Durham ranks fourth among cities in the state of North Carolina. This means that it is one of the most populous cities in the state, but it is also one of the areas where you will find the best water quality. In this article, we’ll take a look at some interesting facts about the water quality in Durham and how you can determine if it is good enough for you and your family to bathe in.

Durham is fortunate to have an incredibly high number of lakes, many of which are trout dependent, as well as several lakes with bodies of water that are considered babbling. This means that when you are looking at your water quality in Durham, you should look at the trout, the ducks, and any other wildlife that may be in the area as well. In fact, many local groups and organizations have been formed just to ensure that any wildlife that is able to survive in the area gets the habitat that they need.

If you are looking for a healthy body of water for a backyard pool or for a professional fishing lake, you will find that Durham makes a great choice. Although many people are of the opinion that Durham is among the most polluted of cities in the United States, the water is actually considered to be of excellent quality. Of course, this does not mean that you should ignore the environment when you are trying to bathe in water. However, you will find that there are plenty of reasons to enjoy the environment as well.
