Can You Drink Tap Water in Carson?
Yes, Carson's tap water is generally considered safe to drink as Carson 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, Carson's water utility, Compton-City, Water Dept, 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 Carson was resolved on March 31, 2019. This assessment is based on the Compton-City, Water Dept 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 Carson Tap Water
The most recent publicly available numbers for measured contaminant levels in Carson 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 Carson's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.
Carson Tap Water Safe Drinking Water Act Violation History - Prior 10 Years
Below is a ten year history of violations for the water system named Compton-City, Water Dept for Carson in California. For more details please see the "What do these Violations Mean?" section below.
From Jan. 1, 2019 to March 31, 2019, Carson 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: Total Haloacetic Acids (HAA5), TTHM.
From Oct. 1, 2012 to Dec. 31, 2012, Carson 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, Routine (IDSE) 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 Carson Water?
Based on the EPA’s ECHO Database, 90% of the samples taken from the Carson water system, Compton-City, Water Dept, between sample start date and sample end date, were at or below, 0.0 mg/L of lead in Carson water. This is 0% of the 0.015 mg/L action level. This means 10% of the samples taken from Carson contained more lead.
While Carson 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 Carson 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 - DFSP Norwalk - near Carson 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 Carson 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.

Carson Water Quality Report (Consumer Confidence Report)
The EPA mandates that towns and cities consistently monitor and test their tap water. They must report their findings in an annual Consumer Confidence Report. Below is the most recent water quality report from Carson's Water. If you would like to see the original version of the report, please click here.
CITY OF COMPTON
2020 CONSUMER CONFIDENCE REPORT
Since 1991, California water utilities have been providing information on water served to its consumers. This report is a snapshot of the tap water quality that we provided last year. Included are details about where your water comes from, how it is tested, what is in it, and how it compares with state and federal limits. We strive to keep you informed about the quality of your water, and to provide a reliable and economic supply that meets all regulatory requirements.
Where Does My Tap Water Come From?
Your tap water comes from local, deep groundwater wells within our service area shown on the adjacent map. The quality of groundwater delivered to your home is presented in this report. We also have a connection with the Metropolitan Water District of Southern California’s (MWD) and emergency connections but the connections were not activated in 2020.
How is My Drinking Water Tested?
Your drinking water is tested regularly for unsafe levels of chemicals, radioactivity and bacteria at the source and in the distribution system. We test weekly, monthly, quarterly, annually or less often depending on the substance. State and federal laws allow us to test some substances less than once per year because their levels do not change frequently. All water quality tests are conducted by specially trained technicians in state- certified laboratories.
What Are Drinking Water Standards?
The U.S Environmental Protection Agency (USEPA) limits the amount of certain substances allowed in tap water. In California, the State Water Resources Control Board (State Water Board) regulates tap water quality by enforcing limits that are at least as stringent as the Federal EPA’s. Historically, California limits are more stringent than the Federal ones.
There are two types of these limits, known as standards. Primary standards protect you from substances that could potentially affect your health. Secondary standards regulate substances that affect the aesthetic qualities of water. Regulations set a Maximum Contaminant Level (MCL) for each of the primary and secondary standards. The MCL is the highest level of a substance that is allowed in your drinking water.
Public Health Goals (PHGs) are set by the California Environmental Protection Agency. PHGs provide more information on the quality of drinking water to customers, and are similar to their federal counterparts, Maximum Contaminant Level Goals (MCLGs). PHGs and MCLGs are advisory levels that are nonenforceable. Both PHGs and MCLGs are concentrations of a substance below which there are no known or expected health risks.
How Do I Read the Water Quality Table?
Although we test for over 100 substances, regulations require us to report only those found in your water. The first column of the water quality table lists substances detected in your water. The next columns list the average concentration and range of concentrations found in your drinking water. Following are columns that list the MCL and PHG or MCLG, if appropriate. The last column describes the likely sources of these substances in drinking water.
To review the quality of your drinking water, compare the highest concentration and the MCL. Check for substances greater than the MCL. Exceedence of a primary MCL does not usually constitute an immediate health threat. Rather, it requires testing the source water more frequently for a short duration. If test results show that the water continues to exceed the MCL, the water must be treated to remove the substance, or the source must be removed from service.
Why Do I See So Much Coverage in the News About the Quality Of Tap Water?
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 include:
- Microbial contaminants, including viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife;
-
Inorganic contaminants, such as salts and metals, that 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, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses;
- Organic chemical contaminants, including synthetic and volatile organic chemicals, that are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems;
- Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.
In order to ensure that tap water is safe to drink, the U.S. Environmental Protection Agency (USEPA) and the State Water Resources Control Board (State Water Board) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The State Water Board regulations also establish limits for contaminants in bottled water that must provide the same protection for public health.
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 Federal EPA’s Safe Drinking Water Hotline

If present, elevated levels of lead can cause serious health problem, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with services lines and home plumbing. The City of Compton 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 30 seconds to 2 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 http://www.epa.gov/safewater/lead.
Should I Take Additional Precautions?
Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised 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. The EPA/Centers for Disease Control guidelines on appropriate means to lessen the risk of infection of Cryptosporidium and other microbial contaminants are available from the Federal EPA’s Safe Drinking Water Hotline
Source Water Assessment
The City of Compton completed its source water assessment in 2003. Groundwater supplies are considered most vulnerable to automobile gas stations, high density housing, transportation corridors, and underground storage tanks. A copy of the approved assessment may be obtained by contacting Jose Garfias at jgarfias@comptoncity.org or by phone at (310) 605- 6246 or sending a written request to 205 South Willowbrook Avenue, Compton CA 90220.

FOOTNOTES
- Over 50 regulated and unregulated organic chemicals were analyzed.
- Indicates dates sampled for groundwater sources only.
- California Public Health Goal (PHG). Other advisory levels listed in this column are Federal Maximum Contaminant Level Goals (MCLGs).
- While your drinking water meets the federal and state standard for arsenic, it does contain low levels of arsenic. The arsenic standard balances the current understanding of arsenic’s possible health effects against the costs of removing arsenic from drinking water. The U.S. Environmental Protection Agency continues to research the health effects of low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems.
- Combined Radium 226 + Radium 228 has a Maximum Contaminant Level (MCL) of 5 pCi/L.
- MCL compliance based on 4 consecutive quarters of sampling.
- Running annual average used to calculate average, range, and MCL compliance.
- Maximum Residual Disinfectant Level (MRDL)
- Maximum Residual Disinfectant Level Goal (MRDLG)
- 90th percentile from the most recent sampling at selected customer taps.
- Aluminum has primary and secondary standards.
-
The Notification Level of 1 ug/l for
1,4-Dioxane was exceeded in one well in 2020. There is no regulatory Maximum Contaminant level. Some people who use water containing1,4-dioxane in excess of the Notification Level over many years may experience liver or kidney problems and may have an increased risk of getting cancer, based on studies in laboratory animals.
“Notification Level” means the concentration level of a contaminant in drinking water delivered for human consumption that the department has determined, based on scientific information, does not pose a significant health risk but warrants notification pursuant to Health and Safety Code 116455. Notification levels are

DEFINITIONS
Maximum Contaminant Level (MCL) : The highest level of a contaminant that is allowed in drinking water. Primary MCLs are set as close to the PHGs (or MCLGs) as is economically and technologically feasible. Secondary MCLs are set to protect the odor, taste, and appearance of drinking water.
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 are set by the U.S. Environmental Protection Agency.
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 nessary 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 contaminants.
Notification Level (NL): The level at which notification of the public water system governing body is required. A
Public Health Goal (PHG) : The level of a contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the California Environmental Protection Agency.
Treatment Technique (TT) : A required process intended to reduce the level of a contaminant in drinking water.
Regulatory Action Level (AL) : The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.
Primary Drinking Water Standard (PDWS): MCLs, MRDLs and treatment techniques (TT) for contaminants that affect health, along with their monitoring and reporting requirements.
Secondary Drinking Water Standards (SDWS) : MCLs for contaminants that affect the aesthetic (taste, odor, or appearance) qualities of the drinking water. Contaminants with SDWSs do not affect the health at the MCL levels.
Variances and Exemptions: State Water Board permission to exceed an MCL or not comply with a TT under certain conditions.
UNREGULATED CONTAMINANT MONITORING REGULATION (UCMR- 4)
The Safe Drinking Water Act requires the Environmental Protection Agency (EPA) to identify unregulated contaminants for potential regulations. Every five years, EPA identifies a list of
unregulated contaminants to be monitored for by the nation's water utilities over a three year period. This will occur in

INFORME DE CONFIANZA DE CONSUMIDOR de 2020
Desde 1991, las agencias proveedoras de recursos hidráulicos de California han emitido información sobre el agua que se provee al consumidor. Este informe es una copia del informe sobre la calidad del agua potable que le proveímos el año pasado. Incluímos detalles sobre el origen del agua que toma, cómo se analiza, que contiene, y cómo se compara con los límites estatales y federales. Nos esforzamos por mantenerle informado sobre la calidad de su agua, y proveerle un abastecimiento confiable y económico que cumpla con todos los requisitios.
¿De Dónde Proviene el Aqua que Tomo?
El agua del grifo proviene de pozos de agua subterránea profundos locales dentro de nuestra área de servicio que se muestra en el mapa adyacente. En este informe se
presenta la calidad del agua subterránea que llega a su hogar. También tenemos una conexión con el Distrito Metropolitano de Agua del Sur de California (MWD) y conexiones de emergencia, pero las conexiones no se activaron en 2020.
¿Cómo Se Analiza Mi Agua Potable?
El agua que toma se analiza regularmente para asegurarnos de que no halla niveles altos de sustancias químicas, de radioactividad o de bacteria en el sistema de distribución y en las tomas de servicios. Estos análisis se llevan a cabo semanal, mensual, trimestral, y anualmente o con más frecuencia, dependiendo de la sustancia analizada. Bajo las leyes estatales y federales, se nos permite analizar algunas sustancias menos frecuentemente que los periodos anuales porque los resultados no cambian.
¿Cuales Son Los Estándares del Agua Potable?
La Agencia de Protección Ambiental de Estados Unidos (USEPA) limita la cantidad de ciertos contaminantes en el agua del grifo. En California, la Junta de Control de Recursos Hídricos del Estado (State Water Board) regula la calidad del agua de beber siguiendo normas que sean al menos tan estrictas como las normas federales. Históricamente, los estandares de California han sido más estrictos que los federales.
Hay dos tipos de límites conocidos como estándares. Los estándares primarios lo protegen de sustancias que potencialmente podrían afectar su salud. Las normas establecen los Niveles Contaminantes Máximos (MCL, en inglés) que se permite del contaminante primario o secundario en el agua de beber. Los abastecedores de agua deben asegurarse de que la calidad de esta cumpla con los Niveles Contaminantes Máximos (o MCLs, en
inglés). No todas las sustancias tienen un Nivel Contaminante Máximo. El plomo y el cobre, por ejemplo, son regulados, por cierto nivel de acción. Si cualquier sustancia química sobrepasa el nivel de acción, se dará la necesidad de un proceso de tratamiento para rebajar los niveles en el agua de beber. Los abastecedores de agua deben cumplir con los Niveles Contaminantes Máximos para asegurar la calidad del agua.
Las Metas para la Salud Pública (MSP [o PHGs, en inglés]) son establecidas por la agencia estatal de
¿Cómo Interpreto Mi Informe de Calidad del Agua? Aunque analizamos más de 100 sustancias, las normas nos requireren que reportemos solo aquellas que se encuentran en el agua. La primer columna en la tabla de la calidad de agua muestra la lista de las sustancias detectadas en el agua. La siguiente columna muestra la lista de la concentracion promedio y el rango de concentraciones que se hallan encontrado en el agua que usted toma. En seguida están las listas de el MCL, el PHG y el MCLG, si estos son apropiados. La última columna describe las probables fuentes u origen de las sustancias detectadas en el agua potable.
Para revisar la calidad de su agua de beber, compare los valores por encima del promedio, mínimos y máximos y el Nivel Contaminante Máximo. Revise todos los químicos que se encuentran por encima del Nivel Contaminante Máximo. Si los químicos sobrepasan el Nivel Contaminante Máximo no significa que sea detrimental a la salud de inmediato. Más bien, se requiere que se realizen análisis más frecuentemente en el abastecimiento del agua por un corto período. Si los resultados muestran sobrepasar el MCL, el agua debe ser tratada para remover esa sustancia, o el abastecimiento de esta debe decomisionarse.
¿Por Qué Hay Tanta Publicidad Sobre La Calidad Del Agua Potable?
Las fuentes del agua potable (de ambas agua de la llave y agua embotellada) incluye ríos, lagos, arroyos, lagunas, embalses, manantiales, y pozos. Al pasar el agua por la superficie de los suelos o por la tierra, se disuelven minerales que ocurren al natural, y en algunas ocasiones, material radioactivo, al igual que pueden levantar sustancias generadas por la presencia de animales o por actividades humanas.
Entre los contaminantes que puenden existir en las fuentes de agua se incluyen:
- Contaminantes microbiales como los viruses y la bacteria, los que pueden venir de las plantas de
tratamiento de aguas negras, de los sistemas sépticos, de las operaciones de ganadería, y de la vida salvaje;
- Contaminantes inorgánicos, como las sales y los metales, los cuales pueden ocurrir naturalmente o como resultado del desagüe pluvial, industrial, o de alcantarillado, producción de gas natural y petróleo, minas y agricultura.
- Pesticidas y herbicidas, los cuales pueden venir de varias fuentes tales como la agricultura, del desagüe pluvial, y de usos residenciales;
- Contaminantes de otras sustancias químicas orgánicas, incluyendo químicos orgánicos volátiles y sintéticos que son productos de procesos industriales y de la producción de petróleo, y que pueden provenir de las estaciones de gasolina, desagües pluviales urbanos, y agricultura applicación y de sistemas sépticos;
- Contaminantes radioactivos, los cuales puenden ocurrir naturalmente o que puenden ser resultados de las actividades de la producción de gas natural y minería.
Con el fin de garantizar que el agua del grifo es segura para beber, la Agencia de Protección Ambiental (EPA) y la Junta de Control de Recursos Hídricos del Estado (Consejo de Estado) prescriben regulaciones que limitan la cantidad de ciertos contaminantes en el agua suministrada por los sistemas públicos de agua. El Reglamento del Consejo de Estado también establecen límites de contaminantes en el agua embotellada que debe proporcionar la misma protección para la salud pública.
Toda el agua potable, incluyendo el agua embotellada, puede contener cantidades pequeñas de ciertos contaminantes. La presencia de contaminantes no necesariamente indica que haya algún riesgo de salud.

Si presente, los niveles elevados del plomo pueden causar el problema de salud serio, sobre todo para mujeres embarazadas y chiquitos. El plomo en el agua potable es principalmente de materiales y componentes asociados con líneas de servicios y a casa fontanería. La Ciudad de Compton es responsable de proporcionar el agua potable de alta calidad, pero no puede controlar la variedad de materiales usados en la fontanería de componentes. Cuando su echar agua ha estado sentándose durante varias horas, usted puede minimizar el potencial para la exposición de plomo limpiando con agua su grifo durante
30 segundos a 2 minutos antes de usar el echar agua para beber o cocinarse. Si usted está preocupado por el plomo en su echar agua, usted puede desear hacer probar su echar agua. La información en el plomo en el agua potable, probando métodos, y pasos que usted puede tomar para minimizar la exposición está disponible de la Línea directa de Agua Potable Segura o en http://www.epa.gov/safewater/lead.
¿Debería Tomar Otras Precauciones?
Algunas personas pueden ser más vulnerables a los contaminantes en el agua potable que el público en general. Las personas que tienen problemas imunológicos, o sea esas personas que estén en tratamiento por medio de quimoterapia cancerosa; personas que tienen órganos transplantados, o personas con SIDA o desordenes imunológicos, personas de edad avanzada, y los bebés que son particularmente suseptibles a ciertas infecciones. Estas personas deben de consultar a sus proveedores de salud médica. Las guias de la USEPA/Centros de Control de Enfermedades aconsejan cómo disminuir los riesgos para prevenir la infección de Cryptosporidium y otros contaminantes microbiales están disponibles por teléfono de la USEPA encargada de proteger el agua potable al teléfono
Valoración de su Abastecimiento de Agua
La ciudad de Compton terminó su evaluación de las fuentes de agua en 2003. Suministros de agua subterránea se consideran más vulnerables a las estaciones de gas de automóviles, viviendas, corredores de transporte de alta densidad, y los tanques de almacenamiento subterráneos.

Algunos consejos útiles para la conservación del agua
- Repare los grifos que gotean en su hogar: ahorre hasta 20 galones por día por cada fuga detenida
- Ahorre entre 15 y 50 galones cada vez lavando solo cargas completas de ropa
- Ajuste sus aspersores para que el agua caiga en su césped / jardín, no en la acera / entrada de autos - ahorre 500 galones por mes
- Use mantillo orgánico alrededor de las plantas para reducir la evaporación: ahorre cientos de galones al año
- Use un cabezal de ducha que ahorre agua. Son económicos, fáciles de instalar y pueden ahorrarle hasta 750 galones al mes.
