Can You Drink Tap Water in Wilmington?

Yes, Wilmington's tap water is generally considered safe to drink as Wilmington 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, the city's water provider website, or Wilmington's local Twitter account.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Wilmington's water utility, Cfpua-Wilmington, had 3 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 Wilmington was resolved on March 31, 2018. This assessment is based on the Cfpua-Wilmington 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 Wilmington Tap Water

The most recent publicly available numbers for measured contaminant levels in Wilmington 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 Wilmington's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

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

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

For the compliance period beginning July 1, 2020, Wilmington 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, 2019, Wilmington 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, 2019 to June 30, 2019, Wilmington 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 March 1, 2018 to March 31, 2018, Wilmington had 1 non-health based Safe Drinking Water Act violation with the violation category being Monitoring Violation, more specifically, the violation code was Monitoring, Routine (RTCR) which falls into the Microbials rule code group, and the Total Coliform Rules rule code family for the following contaminant code: Revised Total Coliform Rule.

From Oct. 1, 2013 to Dec. 31, 2013, Wilmington 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, Regular which falls into the Chemicals rule code group, and the Synthetic Organic Chemicals rule code family for the following contaminant code: Dalapon.

Is there Lead in Wilmington Water?

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

While Wilmington 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 Wilmington 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 - Military Ocean Terminal Sunny Point - near Wilmington 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 Wilmington 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.

Annual Drinking Water Quality Report

Cape Fear Public Utility Authority 2020 Drinking Water Quality Results

From the

Executive Director

This Annual Water Quality Report is your guide to the drinking water supplied by Cape Fear Public Utility Authority to you, our customers. It includes important information about the rigorous testing, analysis, and treatment CFPUA’s staff performs each day to

provide high quality water service.

Consider this our official report card for 2020, detailing how we are meeting or exceeding the many drinking water standards established by the State of North Carolina and the U.S. Environmental Protection Agency. I am proud to share these results with you.

The COVID-19 pandemic was a stark reminder of the importance of CFPUA’s mission to main- tain reliable, quality water service for our community. By the time the first cases of COVID-19 were reported in New Hanover County in early 2020, staff was implementing plans for remote work and additional precautions at CFPUA facilities. During the spring and summer peak of cases, staff even sheltered in-place at our Sweeney and Richardson water treatment plants to reduce the chances of staffing shortages among these essential employees (learn more on page 3 of this report). I am grateful to all of CFPUA’s staff, whose hard work and flexibility kept our community’s critical water and wastewater services flowing during a difficult year.

The past year also saw steady progress on our Sweeney Treatment Enhancements Project, which will significantly increase the Sweeney Plant’s ability to remove PFAS, such as GenX, from raw Cape Fear River water. This $43 million investment by CFPUA will add eight new Granular Activated Carbon (GAC) filters to our Sweeney Plant, which serves approximately 80 percent of CFPUA’s customers. We look forward to these state-of-the-art filters coming online at the start of 2022.

Whether innovating to meet the challenges of a pandemic or investing in our region’s infrastructure, everything we do at CFPUA is driven by our commitment to offer the highest possible level of service at the lowest practicable cost to our customers.

Cape Fear Public Utility Authority 2020 Drinking Water Quality Results

Above and Beyond

From April to June 2020, staff sheltered in-place at CFPUA’s water treatment plants as COVID cases spiked.

With cases of COVID-19 rising in New Hanover County, CFPUA leaders moved in spring 2020

to protect employees. Among the most important priorities: making sure that water treatment plants consistently had healthy staff to provide critical water services to CFPUA’s customers during the pandemic.

Staff determined that the best way to protect employees from COVID transmission was by limiting contact with the public. While CFPUA’s facilities were closed to the public in April, rented trailers were dispatched to the Sweeney and Richardson water treatment plants, allowing staff to temporarily shelter in- place.

Each trailer -- fully furnished and supplied with food and necessities -- became an office-home for CFPUA’s wa- ter plant staff. Team members worked and lived at the plants for 7-day shifts, trading off each week with an- other team of operators before heading home for a weeklong break. A support team of other employees handled food and supply drops, allowing plant oper- ators to stay safely isolated.

“We understand there’re 10 people in this world that can run this plant and that’s us, so we can’t be selfish.

We have to isolate,” Water Control Operator Michael Brock Dombrowski said this summer while working from the

Sweeney Plant. “Myself and my fellow operators understand we are essential employees, and we take pride in our service.”

Staff still found ways to safely socialize, whether over FaceTime with family or socially distant dinners with co-workers.

“It’s been pretty nice,” Water Control Operator Chris Fulcher said at the time. “Me and my fellow operators, I think we’ve all got a little closer.”

By late June the spread of COVID-19 had slowed consider- ably in the region, and CFPUA ended the trailer program, with staff returning to regular shifts but keeping safety protocols in place. The program, which cost CFPUA rough-

ly $160,000 per month, ensured that water treatment plants ran consistently throughout the peak of the pandemic.

“I just wanted to tell CFPUA leadership that I thank them, because they’ve really taken good care of us here,” Water Control Operator Vatrice Robinson said. “They did go over and above for us. And I thank our families for having our backs. We wouldn’t be able to do this without them.”

Water

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not neces- sarily indicate that water poses a health risk. More information about contaminants and

potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).

Some people may be more vulnerable to contaminants in drinking water than the general pop- ulation. Immuno-compromised persons such as persons with cancer undergoing chemother- apy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. CFPUA is responsible for providing high

quality drinking water but cannot control the variety of materials used in plumbing compo- nents. When your water has been sitting for several hours, you can mini-

mize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water

for drinking or cooking. If you are

7

www.cfpua.org | @CFPUA

concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is avail- able from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.

Across the nation, rivers, lakes, streams, ponds, reservoirs, springs, and wells are sources of drinking water (both tap and bottled). As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up contaminants resulting from animal or human activity. Contaminants that may be present in source water include:

Microbial Contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, or wildlife.

Inorganic Contaminants, such as salts and metals, which can be naturally occurring or may result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

Pesticides and Herbicides, which may come from a variety of sources such as agricul- ture, urban stormwater runoff, and residential uses.

Organic Chemical Contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production and may also come from gas stations, urban stormwater runoff, and septic systems.

Radioactive Contaminants, which can be naturally occurring or may be the result of oil and gas production and mining activities.

To ensure that tap water is safe to drink, EPA prescribes regulations that limit the amounts of certain contaminants in water provided by public water systems. FDA regulations establish lim- its for substances in bottled water to provide protection for public health.

Cape Fear Public Utility Authority 2020 Drinking Water Quality Results

Lead and

Home Plumbing

Lead in drinking water has been a concern in the water and wastewater industries for de- cades. The primary sources of lead in drinking water are corrossion in drinking water sys- tems and internal plumbing appliances maintained by homeowners.

In 1991, the EPA introduced the Lead and Copper Rule (LCR) to ensure public water suppliers manage lead and copper in drinking water. Public water suppliers have several tools to make sure they are meeting the requirements of this rule.

To effectively monitor and manage lead and copper in drinking water, public water suppliers often implement corrosion-control measures. Water treatment operators maintain pH levels and add orthophosphate to the water to protect against corrosion in the plumbing and pipes in the water system, homes and businesses. To monitor effectiveness, CFPUA staff regularly test lead and copper levels in our customer’s homes and frequently test water quality parameters throughout the water service area.

CFPUA’s corrosion-control program has successfully managed the threat of lead in our drinking water. However, we cannot control the variety of materials used in internal plumbing compo- nents—the private parts of water systems that are owned and maintained by home and busi- ness owners.

In older areas of New Hanover County, homes may rely on aging plumbing systems that ha- ven’t been updated to meet newer standards. When internal plumbing components contain lead, residents and customers are more likely to be exposed to these metals as they leach into drinking water from faucets and other plumbing materials.

Reducing Lead Exposure at Home

  • Use only cold water for drinking, cooking, and making baby formula.
  • Boiling water does not remove lead from water.
  • Regularly clean your faucet’s screen (also known as an aerator).
  • Before use, flush your pipes by running your tap for at least 30 seconds.
  • Contact CFPUA to learn more about sources of

Water Disinfection and

Health Effects

Disinfecting source water is a critical part of any water treatment process. Chlorine and other disinfectants eliminate water-borne pathogens such as Giardia, Cryptosporidium, E. Coli, bacteria, and viruses. These microbial pathogens are known to cause gastroin-

testinal illnesses and other health issues. Because these pathogens are found in the Cape Fear River, the water source for the Sweeney Water Treatment Plant, CFPUA uses chlorine to treat our water prior to its distribution. The Richardson and Monterey Heights water systems also undergo disinfection.

Chlorine treatment has proven to be a transformative achievement in public health. Intro- duced as the solution to the 1850 cholera epidemic in London, chlorine became a widely used water disinfectant by the 1900s.

Unfortunately, chlorine and other disinfectants may cause problems once in the distribution system. They can react with naturally occurring compounds in water to form byproducts such as Trihalomethanes (THM), Haloacetic acids (HAA), Chlorite, and Bromate. According to the EPA, some disinfection byproducts are “suspected to cause bladder cancer and reproductive effects in humans.” To ensure that public water suppliers such as CFPUA provide clean drinking water, the U.S. Environmental Protection Agency (EPA) developed the Stage 2 Disinfection Byproduct rule.

CFPUA developed a plan to not only meet but surpass state and federal regulations. As part of the plan, 17 aeration systems have been installed at the Sweeney plant. These systems reduce formation of disinfection byproducts by spraying fine, uniform particles of water into the air.

This process allows volatile compounds to escape into the atmosphere. Without this escape mechanism, these volatile compounds could react with chlorine and other disinfectants to cre- ate disinfection byproducts. The effectiveness of the aeration systems in reducing disinfection byproducts is evident in CFPUA’s consistent compliance with the EPA Stage 2 Rule. Sweeney’s treatment process also includes ozone and ultraviolet light disinfection.

CFPUA also practices routine water system flushing. This helps maintain water pressure and pipe integrity and minimizes the formation of disinfection byproducts. During flushing, water is forced through pipes and out of fire hydrants at a high velocity, removing accumulated min- eral sediment until the water is clear. Because disinfection byproducts are more easily formed at high temperatures, CFPUA conducts flushing during the summer months. CFPUA conducts sampling to confirm that these protocols effectively reduce disinfection byproducts and ensure compliance with state and federal requirements.

Cape Fear Public Utility Authority 2020 Drinking Water Quality Results

2020 Drinking Water Quality Results – PWS ID# 04-65-010, Sweeney Water System

We routinely monitor for over 150 contaminants in your drinking water according to Federal and State laws. The tables below list all the drinking water contaminants that we detected in the last round of sampling for each particular contaminant group. The presence of contaminants does not necessarily indicate that water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done January 1 through December 31, 2020. The EPA and the State allow us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year. Some of the data, though representative of the water quality, is more than one year old.

Microbiological | Turbidity | Inorganic Contaminants |

Other Disinfection By-Products | Disinfection Residuals Summary

E.coli - Fecal coliforms and E.coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause short-term effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, some of the elderly, and people with severely-compromised immune systems.

Fecal Indicators (enterococci or coliphage) - Fecal indicators are microbes whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause short-term health effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, some of the elderly, and people with severely compromised immune systems.

*TT: If a system collecting 40 or more samples per month finds greater than 5% of monthly samples are positive in one month, an assessment is required.

** Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of the effectiveness of our filtra-

tion system. The turbidity rule requires that 95% or more of the monthly samples must be less than or equal to 0.3 NTU.

13

Continued on next page

 

www.cfpua.org | @CFPUA

1 TT Violation if: Turbidity > 1 NTU.

2 TT Violation if: Less than 95% of monthly turbidity measurements are < 0.3 NTU.

  • Routine and repeat samples are total coliform-positive and either is E. coli-positive or system fails to take repeat samples following E. coli-positive routine sample or system fails to analyze total coliform-positive repeat sample for E. coli. If either an original routine sample and/or its repeat sample(s) are E. coli positive, a Tier 1 violation exists.

Unregulated Contaminants

The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulations are warranted.

1,4-Dioxane

1,4-Dioxane is a likely human carcinogen, according to the U.S. EPA, and has been found in groundwater at sites throughout the United States. The physical and chemical properties and behavior of 1,4-dioxane create challenges for its characterization and treatment. It is highly mobile and does not readily biodegrade in the environment.

Per- and Polyfluoroalkyl Substances (PFAS)

PFAS are found in a wide range of consumer products that people use daily such as cookware, pizza boxes, and stain repellants. Most people have been exposed to PFAS. Certain PFAS can accumulate and stay in the human body for long periods of time. There is evidence that exposure to PFAS can lead to adverse health outcomes in humans. The most-studied PFAS chemicals are PFOA and PFOS. Studies indicate that PFOA and PFOS can cause reproductive and developmental, liver and kidney, and immunological effects in laboratory animals. Both chemi- cals have caused tumors in animals.

The purpose of the assessments was to determine the susceptibility of each drinking water source (well or surface water intake) to Potential Contam- inant Sources (PCSs). The results of the assessment are available in SWAP Assessment Reports that include maps, background information, and a relative susceptibility rating of Higher, Mod- erate or Lower.

The relative susceptibility rating of each source for the Sweeney Water System was determined by combining the contaminant rating (number and location of PCSs within the assessment area) and the inherent vulnerability rating (i.e., characteristics or existing conditions of the well or watershed and its delineated assessment area). The assessment findings are summarized in the table below:

If you are unable to access your SWAP report on the web, you may mail a written request for a printed copy to: Source Water Assessment Program – Report Request, 1634 Mail Service Center, Ra- leigh, NC 27699-1634, or email requests to swap@ncdenr.gov. Please indicate the system name and number (CFPUA-Wilmington Water System, PWS ID# 04-65-010) and provide your name, mailing address, and phone number. If you have any questions about the SWAP report, please contact the Source Water Assessment staff at 919-707-9098. It is important to understand that a susceptibility rating of “higher” does not imply poor water quality, only the system’s potential to become contaminated by PCSs in the assessment area.

Cape Fear Public Utility Authority 2020 Drinking Water Quality Results

2020 Drinking Water Quality Results – PWS ID# 04-65-232, Richardson Water System

We routinely monitor for over 150 contaminants in your drinking water according to Federal and State laws. The tables below list all the drinking water contaminants that we detected in the last round of sampling for each par- ticular contaminant group. The presence of contaminants does not necessarily indicate that water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done January 1 through December 31, 2020. The EPA and the State allow us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year. Some of the data, though representative of the water quality, is more than one year old.

Microbiological | Inorganic Contaminants | Disinfection Residuals Summary

E.coli - Fecal coliforms and E.coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause short-term effects, such as diarrhea, cramps, nau- sea, headaches, or other symptoms. They may pose a special health risk for infants, young children, some of the elderly, and people with severely-compromised immune systems.

Fecal Indicators (enterococci or coliphage) - Fecal indicators are microbes whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause short-term health effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, some of the elderly, and people with severely compromised immune systems.

Fourth Unregulated Contaminant Monitoring Rule (UCMR4) Contaminants

The 1996 Safe Drinking Water Act (SDWA) amendments require that once every five years EPA issue a new list of no more than 30 unregulated contaminants to be monitored by public water systems.

The fourth Unregulated Contaminant Monitoring Rule (UCMR 4) was published in the Federal Register on De- cember 20, 2016. UCMR 4 requires monitoring for 30 chemical contaminants between 2018 and 2020 using analytical methods developed by EPA and consensus organizations. This monitoring provides a basis for future regulatory actions to protect public health.

Cape Fear Public Utility Authority 2020 Drinking Water Quality Results

Source Water Assessment Program (SWAP)

As part of the Source Water Assessment Program (SWAP), the North Carolina Department of Environ- mental Quality's Public Water Supply Section conducted assessments for all drinking water sources across North Carolina. The purpose of the assessments was to determine the susceptibility of each drinking water source (well or surface water intake) to Potential Contaminant Sources (PCSs). The results of the assessment are available in SWAP Assessment Reports that include maps, background information, and a relative susceptibility rating of Higher, Moderate or Lower.

The relative susceptibility rating of each source for the Richardson Water System was determined by combining the contaminant rating (number and location of PCSs within the assessment area) and the inherent vulnerability rating (i.e., characteristics or existing conditions of the well or watershed and its delineated assessment area).

Cape Fear Public Utility Authority 2020 Drinking Water Quality Results

Unregulated Contaminants

The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulat- ed contaminants in drinking water and whether future regulations are warranted.

Per- and Polyfluoroalkyl Substances (PFAS)

PFAS are found in a wide range of consumer products that people use daily such as cookware, pizza boxes, and stain repellants. Most people have been exposed to PFAS. Certain PFAS can accumulate and stay in the human body for long periods of time. There is evidence that exposure to PFAS can lead to adverse health outcomes in humans. The most-studied PFAS chemicals are PFOA and PFOS. Studies indicate that PFOA and PFOS can cause reproductive and developmental, liver and kidney, and immunological effects in laboratory animals. Both chemi- cals have caused tumors in animals.

Source Water Assessment Program (SWAP)

As part of the Source Water Assessment Program (SWAP), the North Carolina Department of Environmental Quality's Public Water Supply Section conducted assessments for all drinking water sources across North Carolina. The purpose of the assessments was to determine the susceptibility of each drinking water source (well or surface water intake) to Potential Contam- inant Sources (PCSs). The results of the assessment are available in SWAP Assessment Reports that include maps, background information, and a relative susceptibility rating of Higher, Mod- erate or Lower.

The relative susceptibility rating of each source for the Monterey Heights Water System was determined by combining the contaminant rating (number and location of PCSs within the as- sessment area) and the inherent vulnerability rating (i.e., characteristics or existing conditions of the well or watershed and its delineated assessment area). The assessment findings are summarized in the table below:

The complete SWAP Assessment report for CFPUA/Monterey Heights Water System may be viewed on the Web at: www.ncwater.org/?page=600. Note that because SWAP results and reports are periodically updated by the PWS Section, the results available on this web site may differ from the results that were available at the time this CCR was prepared. If you are unable to access your SWAP report on the web, you may mail a written request for a printed copy to: Source Water Assessment Program – Report Request, 1634 Mail Service Center, Raleigh, NC 27699-1634, or email requests to swap@ncdenr.gov. Please indicate the system name and number (CFPUA/Monterey Heights Water System, PWS ID# 04-65-137) and provide your name, mailing address, and phone number. If you have any questions about the SWAP report, please contact the Source Water Assessment staff at 919-707-9098.

It is important to understand that a susceptibility rating of “higher” does not imply poor water quality, only the system’s potential to become contaminated by PCSs in the assessment area. 28

Always take extra precautions, the water may be safe to drink when it leaves the sewage treatment plant but it may pick up pollutants during its way to your tap. We advise that you ask locals or hotel staff about the water quality. Also, note that different cities have different water mineral contents.

Sources and Resources

'

Many people do not realize that tap water in Wilmington, DE is just as safe as bottled water from any location. Unfortunately, this is not always the case. There are chemicals that seep into the ground and contaminate our drinking water supplies. This is a problem that has plagued the country for a long time, yet we seem to expect worse from our tap water. Many of us have purchased expensive home filtration systems, only to find out that they do not remove all of the contaminants that are in our tap water.

Your body can only tell you if it is clean or not. If it has an unpleasant taste, then it probably contains some level of contaminants. You can also test your water yourself by filling up a cup with tap water and throwing it in the garbage can. You will soon notice the difference between the odor and the taste. Many times we simply assume that our tap water tastes bad because we do not like to taste anything else.

So, how do we know that our tap wat
