Can You Drink Tap Water in Trenton City?

Yes, Trenton City's tap water is generally considered safe to drink as Trenton City 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, Trenton City's water utility, Trenton Water Works, had 5 health-based violations and 13 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 Trenton City was resolved on Dec. 31, 2021. There has been an active violation for Public Notice since Aug. 18, 2021. This assessment is based on the Trenton Water Works 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 Trenton City Tap Water

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

Is there Lead in Trenton City Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Trenton City water system, Trenton Water Works, between sample start date and sample end date, were at or below, 0.00741 mg/L of lead in Trenton City water. This is 49.4% of the 0.015 mg/L action level. This means 10% of the samples taken from Trenton City contained more lead.

While Trenton City water testing may have found 0.00741 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 Trenton City 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 - Naval Air Warfare Center Trenton - near Trenton City 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 Trenton City 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.

SDWA Table Key

Field Description
Compliance Period Dates of the compliance period.
Status Current status of the violation.
  • Resolved - The violation has at least one resolving enforcement action. In SDWIS, this indicates that either the system has returned to compliance from the violation, the rule that was violated was no longer applicable, or no further action was needed.
  • Archived - The violation is not Resolved, but is more than five years past its compliance period end date. In keeping with the Enforcement Response Policy, the violation no longer contributes to the public water system's overall compliance status. Unresolved violations are also marked as Archived when a system ceases operations (becomes inactive).
  • Addressed - The violation is not Resolved or Archived, and is addressed by one or more formal enforcement actions.
  • Unaddressed - The violation is not Resolved or Archived, and has not been addressed by formal enforcement.

TWW has developed a program to reduce the exposure to lead for their customers in the drinking water as a response to an exceedance of the Lead and Copper Rule. TWW has authorized $50,000,000.00 in contract work to replace approximately 8,000 lead service lines by 2022. Phase 2 is anticipated to be in place by July 2021. TWW met water quality regulations for lead throughout the course of 2019 and 2020.

TWW entered into an Administrative Consent Order (ACO) dated Feb. 2018 with the New Jersey Department of Environmental Protection to cover the finished water reservoir. Under the ACO, the construction of the cover is scheduled to be completed by July 31, 2023. The ACO also addresses additional requirements for TWW’s system operation, emergency response plan and system staffing.

TWW entered into a second Administrative Consent Order dated July 26, 2018 on the New Jersey Safe Drinking Water Regulations, specifically N.J.A.C. 7:10-5.1,5.2(a)(9), incorporated by reference, the Lead and Copper Rule 40 CFR 141.80 et. Seq.

For more information, please contact the Water Filtration plant Laboratory at 609-989-3208 or Trenton Water Works, 333 Cortland Street, PO Box 528, Trenton NJ, 08604-0528.

Corrective Actions for Disinfectant Byproduct Levels

TWW implemented several corrective actions to bring down DBP levels. The corrective actions included: upgrading of chlorine tanks, replacing filter media on 12 filters in 2019 and another 12 in 2020, and more frequent flushing of distribution system. TWWs DBPs have been within regulatory limits since February 2019.

COVID-19 and Drinking Water

TWW continues to provide safe drinking water to the communities it serves. The COVID-19 Pandemic has not affected TWW’ s ability to continue to provide safe drinking water to its customers.

The coronavirus (COVID-19) pandemic is impacting communities throughout the world. We are working around the clock to ensure that safe, reliable water service continues to flow.

Capital Improvements

TWW is investing in our infrastructure to improve system reliability, water quality and operational performance. We have developed a six- year capital plan to meet our overall objectives.

Projects currently underway include raw water intake improvement project, superpulsator upgrade, Pennington reservoir replacement project, meter replacement program, water treatment plant facility upgrade, the gravity thickener rehabilitation, water main cleaning, and lead service line replacements.

Acronyms and Definitions

Maximum Contaminant Level (MCL): The highest level of contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

Recommended Upper Limit (RUL): The level of a secondary contaminant in drinking water below which there is no known or expected adverse effect of the taste, color, odor, or appearance of such water, or which may adversely affect the public welfare.

Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contamination.

Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.

Action Level: The concentration of a contaminant that, if exceeded, triggers treatment or other requirements which a water system must follow.

Variances and Exceptions: State or EPA permission not to meet a MCL or a treatment technique under certain conditions.

ppm: Concentration in parts per million or milligrams per liter (mg/L); this is equivalent to $0.01 of $10,000.

ppb: Concentration in parts per billion or micrograms per liter (μg/L); this is equivalent to $0.01 of $10,000,000.

pCi/L: Picocuries per liter; a measure of radioactivity.

NLE: No Level Established

NTU: Nephelometric turbidity units (units describing how cloudy a water sample appears).

MFL: million fibers per liter.

<: When seen in the table, it usually refers to below detectable levels.

: Less than or equal to; when seen in the table, it usually refers to below or equal to detectable levels.

Contaminant: Anything found in water (including microorganisms,

minerals, chemicals, radionuclides, etc.) that may be harmful to human health.

RawWater: Water in its natural state prior to any treatment for drinking.

Source Water: Water in its natural state originating from the water- shed that supplies a water system with its raw water.

Watershed: The land area from which water drains into a stream, river, or reservoir.

TreatedWater: Water to be used by a public water system that has received the application of approved water treatment chemicals.

Drinking Water: Water that has been treated to comply with EPA regulations and is pumped to the water customer for use.

Turbidity: Turbidity is a measure of the cloudiness of the water, which is a good indicator of water quality. High turbidity can hinder the effectiveness of disinfectants.

FOOTNOTES

  1. TWW averages 141 samples per month. The requirement is 120 samples monthly. An MCL violation would be triggered if, > 5% of the samples had TC detected or any detection of E-coli.
  2. Beginning in 2017, Trenton Water Works was required to sample 100 sites every six months as are all large systems in the state.
  3. Stage 2 DBPR monitoring is conducted quarterly. The results are shown are from the 2020 quarterly sampling.
  4. The highest Locational Running Annual Average (LRAA) for TTHM and HAA5 is reported per regulation. All LRAAs which exceed the MCL shall be included. The LRAA is the average of the current and three previous quarterly results for each sample site location. The table below shows the quarterly exceedances and the LRAA for those quarters:

  1. Data presented is derived from quarterly sample site results.
  2. Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of water quality. High turbidity can hinder the effectiveness of disinfectants. 99.9% of the turbidity readings in 2020 were below the treatment requirement of 0.3 NTU.
  3. Chlorine residuals are taken during Coliform (bacteria) sampling in the distribution system.
  4. Radioactive Contaminants (radionuclide) sampling is required once every 9-year monitoring period. The current compliance period is 2020-2028. Only detected results are reported. The results presented were sampled in 2014.
  5. Inorganic compounds were tested in September of 2020.
  6. NJDEP standards (SMCL).
  7. Asbestos is sampled every nine years. The result presented was sampled on June 26, 2013.
  8. Unregulated Contaminant Rule sampling assesses the potential risks associated with certain contaminants. The EPA will use this to determine if regulation is warranted.
  9. Cryptosporidium is a microbial pathogen found in surface water throughout the United States. Although filtration removes Cryptoporidium, the most commonly-used filtration methods cannot guarantee 100 percent removal. Our monitoring indicates the presence of these organisms in our source water. Current test methods do not allow us to determine if the organisms are viable or capable of causing disease. Ingestion of Cryptosporidium may cause cryptosporidiosis, an abdominal infection. Symptoms of infection include nausea, diarrhea, and abdominal cramps. Most healthy individuals can overcome the disease within a few weeks. However, immuno-compromised people, infants and small children, and the elderly are at greater risk of developing life-threatening illness. We encourage immuno-compromised individuals to consult their doctor regarding appropriate precautions to take to avoid infection. Cryptosporidium must be ingested to cause disease, and it may spread through means other than drinking water.
  10. Secondary contaminants are non-enforceable guidelines regulating contaminants that may cause cosmetic effects or aesthetic effects in drinking water.
  11. The recommended upper limit for iron is based on unpleasent taste of te water and staining of laundry. Iron is an essential nutrient, but some people who drink water with iron levels well above the recommended upper limit could develop deposits of iron in a number of organs of the body.
    Trenton Water Works also has access to purchased groundwater as emergency water source from an adjacent water system. For further source water information, contact NJDEP Drinking Water Watch.

Drinking Water Quality Results

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, 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 at 1-800-426-4791.

Other Notes:

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. Trenton Water Works is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 2 to 3 minutes before using water for drinking or cooking. If you are 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 available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.

Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer.

Trenton Water Works

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the New Jersey Department of Environmental Protection, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the U.S. EPA (January 2019 - March 2019), tap water provided by this water utility was in compliance with federal health-based drinking water standards.

Utility details

  • Serves: 225000
  • Data available: 2012-2017
  • Data Source: Surface water
  • Total: 5

Contaminants That Exceed Guidelines

Reminder

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.
