Can You Drink Tap Water in Edinburg?
Yes, Edinburg's tap water is generally considered safe to drink as Edinburg 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, Edinburg's water utility, City of Edinburg, had 1 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 Edinburg was resolved on Dec. 31, 2021. This assessment is based on the City of Edinburg 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 Edinburg Tap Water
The most recent publicly available numbers for measured contaminant levels in Edinburg 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 Edinburg's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.
Edinburg 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 Edinburg for Edinburg in Texas. For more details please see the "What do these Violations Mean?" section below.
From Oct. 1, 2021 to Dec. 31, 2021, Edinburg had 1 health-based Safe Drinking Water Act violation with the violation category being Maximum Contaminant Level Violation, more specifically, the violation code was Maximum Contaminant Level Violation, Average 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 code: TTHM.
From Jan. 1, 2019 to Jan. 31, 2019, Edinburg 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.
For the compliance period beginning Oct. 1, 2015, Edinburg had 1 non-health based Safe Drinking Water Act violation with the violation category being Monitoring and Reporting, more specifically, the violation code was Follow-up Or Routine LCR Tap M/R which falls into the Chemicals rule code group, and the Lead and Copper Rule rule code family for the following contaminant code: Lead and Copper Rule.
From Dec. 1, 2012 to Dec. 31, 2012, Edinburg 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 and Reporting (DBP) which falls into the Disinfectants and Disinfection Byproducts Rule rule code group, and the Stage 1 Disinfectants and Disinfection Byproducts Rule rule code family for the following contaminant code: Chlorine dioxide.
Is there Lead in Edinburg Water?
Based on the EPA’s ECHO Database, 90% of the samples taken from the Edinburg water system, City of Edinburg, between sample start date and sample end date, were at or below, 0.0036 mg/L of lead in Edinburg water. This is 24.0% of the 0.015 mg/L action level. This means 10% of the samples taken from Edinburg contained more lead.
While Edinburg water testing may have found 0.0036 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 Edinburg 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 Edinburg 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 Edinburg 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.

ALL drinking water may contain contaminants.
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 water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline

present, elevated levels of lead can cause serious health problems, especially for pregnant wom- en and young children. Lead in drinking water is primarily from materials and components as- sociated with service lines and home plumbing. We are responsible for providing high quality drinking water, but we cannot control the variety of material used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead ex- poser by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cook- ing. If you are concerned about lead in your water, you may wish to have your water tested. In- formation on lead in drinking water, testing methods, and steps you can take to minimize expos- er is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.

Water Sources
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 dissolves naturally-occurring minerals, and in some cases, radioactive material, and can
pick up substances resulting from the presence of animals or from human activity.
Contaminants that may be present in source water before treatment include: Mi-
crobial contaminants, such as viruses & bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, & wildlife. In- organic contaminants, such as salts & metals, which can be naturally-occurring or results from urban storm water runoff, industrial or domestic wastewater dis- charges, oil & gas production, mining, or farming. Pesticides & herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff,
-
residential uses. Radioactive contaminants, which can be
naturally-occurring or be the results of oil & gas production & mining activities. Organic chemical con- taminants, including synthetic & volatile organic chemicals, which areby-products of industrial processes & petroleum production, & can also come from gas sta- tions, urban storm water runoff, & septic systems.

Cryptosporidium Monitoring Information
Cryptosporidium is a microbial pathogen that may be found in water contaminated by feces. Although filtration removes Cryptosporidium, it cannot guarantee 100 percent removal nor can the testing methods determine if the organisms are alive and capable of causing cryptosporidio- sis, an abdominal infection with nausea, diarrhea and abdominal cramps that may occur after ingestion of contaminated water. The following results were acquired from untreated water coming into our raw water reservoir; prior to any chemical treatment.

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. This water supply is responsible for providing high quality drinking water, but we 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 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about the lead in your water, you may wish to have your water tested. Infor- mation on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at

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.
