Can You Drink Tap Water in National City?
Yes, National City's tap water is generally considered safe to drink as National 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, the city's water provider website, or National City's local Twitter account.
According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, National City's water utility, Cal-Am Water Coronado, had 0 violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. This assessment is based on the Cal-Am Water Coronado 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 National City Tap Water
The most recent publicly available numbers for measured contaminant levels in National 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 National City's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.
National City Tap Water Safe Drinking Water Act Violation History - Prior 10 Years
Below is a ten year history of violations for the water system named Cal-Am Water Coronado for National City in California. For more details please see the "What do these Violations Mean?" section below.
Is there Lead in National City Water?
Based on the EPA’s ECHO Database, 90% of the samples taken from the National City water system, Cal-Am Water Coronado, between sample start date and sample end date, were at or below, 0.001 mg/L of lead in National City water. This is 6.7% of the 0.015 mg/L action level. This means 10% of the samples taken from National City contained more lead.
While National City water testing may have found 0.001 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 National 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 no military bases near National 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 National 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
- Maximum contaminant levels (MCLs) - maximum allowed contaminant level was exceeded.
- Maximum residual disinfectant levels (MRDLs) - maximum allowed disinfectant level was exceeded.
- Other violations (Other) - the exact required process to reduce the amounts of contaminants in drinking water was not followed.
Non-Health Based Violations
- 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.
- 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.
- Other violations (Other) - miscellaneous violations, such as failure to issue annual consumer confidence reports or maintain required records.

WHERE YOUR WATER COMES FROM
The Coronado water system is served entirely by treated surface water purchased from the City of San Diego. The City of San Diego obtains 80 to 90 percent of its raw surface water supplies from the San Diego County Water Authority and the remainder from local reservoirs. The San Diego County Water Authority in turn obtains most of its supply from the Metropolitan Water District of Southern California (MWDSC) as well as through transfers from other water agencies. MWDSC has two main raw water sources: the Colorado River and the Sacramento River Delta. Water is conveyed to MWDSC via the Colorado and California aqueducts. The MWDSC water is then conveyed to the San Diego County area via the San Diego County Water Authority and accounts for approximately 80 to 90 percent of the City of San Diego’s water supply. The City of San Diego has three water treatment plants that treat its available raw water supplies. The Coronado System receives its drinking water from only two of the City’s three water treatment plants (WTPs): Alvarado and Otay. The City of San Diego water quality data presented represents the water quality data only taken from the Alvarado (Alv) and Otay WTPs. The water from the City’s Miramar WTP does not reach the Coronado water system and is not included. In February 2011, the City of San Diego began fluoridating the water it produces at all its treatment plants at an optimized target level of 0.6 mg/L.

UNREGULATED CONTAMINANT MONITORING RULE (UCMR)
The EPA created the Unregulated Contaminants Monitoring Rule (UCMR) to assist them in determining the occurrence of unregulated contaminants in drinking water and whether new regulations are warranted. The first Unregulated Contaminants Monitoring Rule (UCMR1) testing was completed in 2003 for a list of contaminants specified by the EPA. Unregulated contaminants are those for which the EPA has not established drinking water standards. UCMR2 testing was conducted between November 2008 and August 2009, and UCMR3 assessment monitoring was conducted between January 2013 and December 2016. The fourth list of contaminants to monitor as part of the UCMR was published by the EPA in December 2016. UCMR4 testing began in 2018 and was completed in 2020. The results from the UCMR monitoring are reported directly to the EPA. The results of this monitoring are incorporated in the data tables in this report as appropriate. For more information, contact our Customer Service Center at

PFOA/PFOS Monitoring
PFAS refers to per- and polyfluoroalkyl substances, a class of
In accordance with Orders received from the Division of Drinking Water (DDW) California American Water is sampling designated sources for PFAS constituents. In 2019 DDW established Notification Levels (NLs) at 6.5 ppt for the PFAS constituents perfluorooctanesulfonic acid (PFOS) and 5.1 ppt for perfluorooctanoic acid (PFOA) in drinking water. In 2020 DDW established Consumer Confidence Detection Levels (CCRDL) of 4 ppt for both PFOS and PFOA.
The science and regulation of PFAS and other contaminants is always evolving, and California American Water strives to be a leader in research and development. PFAS contamination is one of the most rapidly changing areas in the drinking water field. We have invested in our own independent research, as well as engaging with other experts in the field to understand PFAS occurrence in the environment. We are also actively assessing treatment technologies that can effectively remove PFAS from drinking water, because we believe that investment in research is critically important to addressing this issue.

WATER QUALITY STATEMENT
We are pleased to report that during calendar year 2020, the results of testing of your drinking water complied with all state and federal drinking water requirements.
For your information, we have compiled a list in the table below showing the testing of your drinking water during 2020. The Division of Drinking Water allows us to monitor for some contaminants less than once per year because the concentration of the contaminants does not change frequently. Some of our data, though representative, are more than one year old.

UNREGULATED CONTAMINANT MONITORING
Unregulated contaminants are those for which the EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist the EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is necessary. Every five years, the EPA issues a new list of no more than 30 unregulated contaminants to be monitored.

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.
