Can You Drink Tap Water in Pueblo?

Yes, Pueblo's tap water is generally considered safe to drink as Pueblo 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 Pueblo's local Twitter account.

According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Pueblo's water utility, Pueblo Board of Ww, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. The last violation for Pueblo was resolved on Dec. 31, 2018. This assessment is based on the Pueblo Board of Ww 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 Pueblo Tap Water

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

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

Below is a ten year history of violations for the water system named Pueblo Board of Ww for Pueblo in Colorado. For more details please see the "What do these Violations Mean?" section below.

From Oct. 1, 2018 to Dec. 31, 2018, Pueblo had 2 non-health based Safe Drinking Water Act violations with the violation category being Monitoring and Reporting, more specifically, the violation code was Monitoring and Reporting (DBP) which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 2 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant codes: TTHM, Total Haloacetic Acids (HAA5).

Is there Lead in Pueblo Water?

Based on the EPA’s ECHO Database, 90% of the samples taken from the Pueblo water system, Pueblo Board of Ww, between sample start date and sample end date, were at or below, 0.0023 mg/L of lead in Pueblo water. This is 15.3% of the 0.015 mg/L action level. This means 10% of the samples taken from Pueblo contained more lead.

While Pueblo water testing may have found 0.0023 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 Pueblo 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 - Pueblo SWMU - near Pueblo 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 Pueblo 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.

Pueblo Water - Frequently Asked Questions

WHAT ABOUT LEAD?
If present, elevated levels of lead can cause serious health prob- lems (especially for pregnant women and young children). It is possible that lead levels at your home may be higher than other homes in the community as a result of materials used in your home’s plumbing. If you are concerned about lead in your water, you may wish to have your water tested. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. Additional information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline (1-800-426-4791) or at: epa.gov/safewater/lead.

Esta es información importante. Si no la pueden leer, necesitan que alguien se la traduzca.

GENERAL INFORMATION

All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environ- mental Protection Agency’s Safe Drinking Water Hotline (1-800-426-4791) or by vis- iting: https://www.epa.gov/ground-water-and-drinking-water.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer un- dergoing 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 of infections. These people should seek advice about drinking water from their health care providers. For more information about contaminants and potential health effects, or to receive a copy of the U.S. Environmental Protec- tion Agency (EPA) and the U.S. Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and microbio- logical contaminants call the EPA Safe Drinking Water Hotline at (1-800-426-4791).

GENERAL INFORMATION

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dis- solves naturally occurring minerals and, in some cases, radioactive material, and can pick up substanc- es resulting from the presence of animals or from human activity. Contaminants that may be present in source water include:

•Microbial contaminants: Viruses and bacteria that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

•Inorganic contaminants: Salts and metals, which can be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

Pesticides and herbicides: May come from a variety of sources, such as agriculture, urban storm wa- ter runoff, and residential uses.

•Radioactive contaminants: Can be naturally occurring or be the result of oil and gas production and mining activities.

•Organic chemical contaminants: Including synthetic and volatile organic chemicals, which are by- products of industrial processes and petroleum production, and also may come from gas stations, urban storm water runoff, and septic systems.

In order to ensure that tap water is safe to drink, the Colorado Department of Public Health and Environ- ment prescribes regulations limiting the amount of certain contaminants in water provided by public wa- ter systems. The Food and Drug Administration regulations establish limits for contaminants in bottled water that must provide the same protection for public health.

WHAT ABOUT LEAD?

If present, elevated levels of lead can cause serious health prob- lems (especially for pregnant women and young children). It is possible that lead levels at your home may be higher than other homes in the community as a result of materials used in your home’s plumbing. If you are concerned about lead in your water, you may wish to have your water tested. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. Additional information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline (1-800-426-4791) or at: epa.gov/safewater/lead.

SWAP

The Colorado Department of Public Health and Environment provided us with a Source Water Assessment Report for our water supply. For gen- eral information, or to obtain a copy of the report, please visit www.colorado.gov/cdphe/ccr. The report is located under “Guidance: Source Water Assessment Reports.” Search the table using: 151500, PUEBLO BOARD OF WW. For more information on the report, contact the CDPHE by calling 303-692-2000. The Source Water Assessment Re- port provides a screening-level eval- uation of potential contamination that could occur. It does not mean that the contamination has or will occur. We use this information to evaluate the need to improve our current wa- ter treatment capabilities and pre- pare for future contamination threats. This can help us ensure that quality water is delivered to your homes. In addition, the assessment results were used to complete a source water protection plan (SWPP) in 2019.

WE TREAT WATER RIGHT

Untreated water flows into the Whitlock Treatment Plant via a pipeline from Pueblo Reservoir. The treatment process begins with the addition of activated carbon to re- move organic, taste and odor compounds. The water is disinfected using chlorine and ammonia (chloramination) and clarified us- ing alum and polymers designed specifically for drinking water treatment processes. The clarified water is brought into the filter plant, where it passes through layers of fine granu- lated anthracite coal and sand, producing a clear, turbidity-free water. Fluoride occurs naturally in the water, but a small amount is added to the filtered water as necessary to meet state standards. Finally, the high quali- ty drinking water is pumped from the treat- ment plant and reaches Pueblo Water through its distribution system.

TERMS & ABBREVIATIONS

 Maximum Contaminant Level (MCL) − The highest level of a

contaminant allowed in drinking water.

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

 Health-Based − A violation of either a MCL or TT.

 Non-Health-Based − A violation that is not a MCL or TT.

 Action Level (AL) − The concentration of a contaminant which, if exceeded, triggers treatment and other regulatory require- ments.

 Maximum Residual Disinfectant Level (MRDL) − The highest

level of a disinfectant allowed in drinking water. There is convinc- ing evidence that addition of a disinfectant is necessary for con- trol of microbial contaminants.

 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.

 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 contaminants.

 Violation (No Abbreviation) − Failure to meet a Colorado Pri- mary Drinking Water Regulation.

 Formal Enforcement Action (No Abbreviation) − Escalated

action taken by the State (due to the risk to public health, or number or severity of violations) to bring a non-compliant water system back into compliance.

 Variance and Exemptions (V/E) − Department permission not

to meet a MCL or treatment technique under certain conditions.

 Gross Alpha (No Abbreviation) − Gross alpha particle activity

compliance value. It includes radium-226, but excludes radon

222, and uranium.

 Picocuries per liter (pCi/L) − Measure of the radioactivity in water.

 Nephelometric Turbidity Unit (NTU) − Measure of the clarity or

cloudiness of water. Turbidity in excess of 5 NTU is just noticea- ble to the typical person.

 Compliance Value (No Abbreviation) – Single or calculated

value used to determine if regulatory contaminant level (e.g. MCL) is met. Examples of calculated values are the 90th Percen- tile, Running Annual Average (RAA) and Locational Running Annual Average (LRAA).

 Average (x-bar) − Typical value.

 Range (R) − Lowest value to the highest value.

 Sample Size (n) − Number or count of values (i.e. number of water samples collected).

 Parts per million = Milligrams per liter (ppm = mg/L) − One

part per million corresponds to one minute in two years or a sin- gle penny in $10,000.

 Parts per billion = Micrograms per liter (ppb = ug/L) − One

part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.

 Not Applicable (N/A) – Does not apply or not available.

 Level 1 Assessment – A study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system.

 Level 2 Assessment – A very detailed study of the water sys- tem to identify potential problems and determine (if possible) why an E. coli MCL violation has occurred and/or why total coli- form bacteria have been found in our water system on multiple occasions.

DETECTED CONTAMINANTS

Pueblo Board of Water Works (Pueblo Water) routinely monitors for contaminants in your drinking water according to Federal and State laws. The following table(s) show all detections found in the period of January 1 to December 31, 2020 unless otherwise noted. The State of Colorado requires us to monitor for certain contami- nants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year, or the system is not considered vulnerable to this type of contamination. Therefore, some of our data, though representa- tive, may be more than one year old. Violations and Formal En- forcement Actions, if any, are reported in the next section of this report.

Note: Only detected contaminants sampled within the last 5 years appear in this report. If no tables appear in this section then no contaminants were detected in the last round of monitoring.

Disinfectants Sampled in the Distribution System

  1. Requirement: At least 95% of samples per period (month or quarter) must be at least 0.2 ppm OR If sample size is less than 40 no more than 1 sample is below 0.2 ppm

Unregulated Contaminants***

EPA has implemented the Unregulated Contaminant Monitoring Rule (UCMR) to collect data for contaminants that are suspected to be present in drinking water and do not have health-based standards set under the Safe Drinking Water Act. EPA uses the results of UCMR monitoring to learn about the occurrence of unregulated contaminants in drinking water and to decide whether or not these contaminants will be regulated in the future. We performed monitoring and reported the analytical results of the monitoring to EPA in accordance with its Unregulated Contaminant Monitoring Rule (UCMR). Once EPA reviews the submitted results, the results are made available in the EPA’s National Contaminant Occurrence Database (NCOD) (epa.gov/dwucmr/national-contaminant-occurrence-database-ncod) Consumers can review UCMR results by accessing the NCOD. Contaminants that were detected during our UCMR sampling and the corresponding analytical results are provided below.

Pueblo

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Colorado Department of Public Health & Environment, 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.

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.

Sources and Resources

The water from the Colorado River Basin flows out of Lake Creek, and it was used by Native Americans for thousands of years as a natural source of drinking water. Today, the Colorado River basin is an important source of drinking water for cities across the United States, but it still supplies drinking water to some of the most rural areas in the country.

So why are some communities that rely heavily on the Colorado River Basin getting contaminated? And can you find a reliable, clean water supply in your city, Pueblo, Colorado?

Because most cities today have run-off treatment plants, they rely on chlorine, which is a byproduct of chlorination. Chlorine is often added to the water supply of our largest metropolitan areas, including Pueblo, to make sure that the water is free of contaminants. Unfortunately, it can also cause problems with certain types of bacteria.

The problem is that this bacterium can cause a variety of health problems, a
