Mr. Christopher Cash

City of Paramount

16400 Colorado Avenue

Paramount, CA 90723

Regarding: UCMR 3 Consumer Confidence Reporting (CCR) 2015

The City of Paramount contracts with the Water Replenishment District of Southern California

(WRD) to test water samples, compile water quality data and assist in development of the

Consumer Confidence Report for the City’s water supply. Through an audit that was conducted

of the City’s most recent 2015 CCR, we concluded that there were several results that the lab had

incorrectly reported and we have revised the report to show the correct data.

The 1996 amendment to the Safe Drinking Water Act (SDWA) requires that once every five

years, the U.S. Environmental Protection Agency (EPA) issue a new list of no more than 30

unregulated contaminants to be monitored by public water systems (PWSs). The Unregulated

Contaminant Monitoring Rule (UCMR) provides EPA and other interested parties with

scientificallyvalid data on the occurrence of contaminants in drinking water. . UCMR 3

monitoring took place from 2013-2015 and included monitoring for 28 chemicals and two

viruses. By definition of the UCMR 3 program, there are no established maximum contaminant

levels for the constituents tested under this program.

The City of Paramount was required to sample from 2013 to 2014 for UCMR 3 and the data was

reported in the 2015 Consumer Confidence Report (CCR). Samples were taken from the wells,

distribution system connections, and imported water connections used as a water supply by the

City of Paramount. UCMR 3 sampling occurred for the City of Paramount on the following

dates:

January 29, 2013

April 29, 2013

May 14, 2013

July 31, 2013

October 31, 2013

January 30, 2014

April 28, 2014

For the CCR Report, all data was combined to determine the overall average and range for each

chemical as required by the State of California. In November 2016, it was discovered that results

for a Chlorate sample from the July 2013 sampling event was incorrectly reported in the CCR as

a Hexavalent Chromium reading. Once it was determined that the sample results for the

Hexavalent Chromium was reported incorrectly, the District audited all UCMR 3 data received

from the contracted laboratory. This review by WRD resulted in a revised CCR for the City of

Paramount that included the correction of the Hexavalent Chromium and Chlorate results, and

also corrected the reported results for Molybdenum, Strontium, and Vanadium as well as the

addition of sampling results for 1,1-Dichlorethane. We notified you of the correction to the

Hexavalent Chromium category in a previous letter. We are now notifying you of the

corrections that were also made to the other four (4) categories mentioned above. The corrected

data has been reported to the State Water Resources Control Board, Division of Drinking Water

who has accepted the results.

In the end, the water supply for the City of Paramount tested as part of the 2015 CCR, which

includes the audited and verified data from July 2013 UCMR 3 requirement, meets or exceeds all

established and regulated safe drinking water standards.

Sincerely,

Robb Whitaker, P.E.

General Manager

Water Replenishment District of Southern California

The City’s Water Consumer Confidence Report has been updated. The

Water Replenishment District (WRD), the independent entity that

conducts testing of the City of Paramount’s water supply, found an

error in the results of their latest testing. That change is reflected in the

chart on the last page.

CITY OF PARAMOUNT 2015 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.

Does My Where

Tap Water Come From? Your tap water comes from 2 sources: groundwater and surface water. We pump groundwater from local, deep wells. We also use

Metropolitan Water District of Southern California’s (MWD) surface water from both the Colorado River and the State Water Project in northern California. These water sources supply our service area shown on the adjacent map. The quality of our groundwater and MWD’s surface water supplies is presented in this report.

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 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 non-enforceable. 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 stormwater 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 stormwater 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 stormwater runoff, agricultural application, 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 USEPA and the State Water Resources Control Board (State Board) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The State 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 USEPA’s Safe Drinking Water Hotline (1-800-426-4791). You can also get more information on tap water by logging on to these helpful web sites: • http://water.epa.gov/drink/standards/hascience.cfm

(Federal EPA’s web site)

• www.waterboards.ca.gov/drinking_water/programs/index.shtml (State Board web site)

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 Paramount 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 USEPA/Centers for Disease Control guidelines on appropriate means to lessen the risk of

infection of Cryptosporidium and other microbial contaminants are available from the USEPA’s Safe Drinking Water Hotline (1-800-426-4791).

Source Water Assessment

MWD completed an assessment of its Colorado River and State Water Project supplies in 2002. Colorado River supplies are considered most vulnerable to recreation, urban/storm water runoff, increasing urbanization in the watershed, and wastewater. State Water Project supplies are considered most vulnerable to urban/storm water runoff, wildlife, agriculture, recreation and wastewater. A copy of the assessment can be obtained by contacting MWD at (213) 217-6850. The City of Paramount conducted an assessment of its groundwater supplies in 2003. Groundwater supplies are considered most vulnerable to chemical/petroleum processing/storage, metal plating/finishing/fabricating, dry cleaners, automobile gas stations, automobile body shops, automobile repair shops, junk/scrap/salvage yards, and plastics/synthetics producers. A copy of the approved assessment may be obtained by contacting the Paramount Public Works Department at (562) 220-2020.

How Can I Participate in Decisions On Water Issues That Affect Me?

The public is welcome to attend Public Works Commission meetings located at Paramount City Hall, 16400 Colorado Avenue, Paramount, CA 90723. Meetings are held on the 1st Thursday of each month at 6:00 pm.

How Do I Contact My Water Agency If I Have Any Questions About Water Quality?

If you have specific questions about your tap water quality, please contact Sarah Ho, Assistant Public Works Director at (562) 220-2020.

Some Helpful Water Conservation Tips

• Fix leaky faucets in your home – save up to 20 gallons every day for every leak stopped

• Save between 15 and 50 gallons each time by only washing full loads of laundry

• Adjust your sprinklers so that water lands on your

lawn/garden, not the sidewalk/driveway – save 500 gallons per month

• Use organic mulch around plants to reduce evaporation

– save hundreds of gallons a year • Use a water-efficient showerhead. They’re

inexpensive, easy to install, and can save you up to 750 gallons a month.

CIUDAD DE PARAMOUNT INFORME CONFIANZA DE CONSUMIDOR 2015

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.

Su agua de la llave proviene de 2 fuentes: de las aguas naturales (subterránea) y de aguas superficiales (de los ríos). Bombeamos aguas naturales de profundos pozos locales. También usamos agua superficial de la agencia Metropolitan Water District del Sur de California (MWD) importada del Río Colorado y del proyecto State Water Project del Norte de California. Estas dos fuentes de agua nos abastecen en las áreas de servicio que se muestran en el mapa adjunto. Este reporte informa sobre la calidad de nuestra agua subterranea y el abastecimiento del agua superficial del MWD.

¿De Dónde Proviene el Aqua que Tomo?

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.

¿Cómo Se Analiza Mi Agua Potable?

La Agencia de Protección Ambiental estadounidense (USEPA) limita la cantidad de ciertas sustancias permitidas en el agua del grifo. En California, la Junta de Control de Recursos Hídricos del Estado (State Board) regula la calidad del agua de beber siguiendo normas que sean al menos tan estrictas como las normas federales. Históricamente, los límites de California son más rigurosos que los Federales.

¿Cuales Son Los Estándares del Agua Potable?

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 California-EPA. Las PHGs proveen más información con respecto a la calidad del agua, y son similares a los reglamentos federales nombrados Metas para Los Niveles de Contaminante Maximos (MNCM [o MCLGs, en inglés]). Las PHGs y MCLGs son metas a nivel

recomendable. Las PHG y MCLG son ambas definidas como los niveles de contaminantes en el agua potable por debajo de los niveles donde no se esperan riesgos a la salud y no enforzables. Ambos niveles PHG y MCLG son concentraciones de una sustancia en las que no hay riesgos a la salud aún conocidos.

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.

¿Cómo Interpreto Mi Informe de Calidad del Agua?

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.

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.

¿Por Qué Hay Tanta Publicidad Sobre La Calidad Del Agua Potable?

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.

A fin de asegurar que el agua de la llave es segura para beber, la Agencia de Protección Ambiental de Los Estados Unidos (USEPA) y el Tablero de Control de Recursos de Echar agua Estatal (Bordo Estatal) prescriben regulaciones que limitan la cantidad de ciertos contaminantes en el agua proporcionada por sistemas de agua públicas. Los reglamentos de Bordo Estata también establecen límites para contaminantes en el agua embotellado 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. Para más información acerca de contaminantes y riesgos a la salud favor de llamar a la USEPA encargada de proteger el agua potable al teléfono (1-800-426-4791).

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 casafontanería. Cuidad de Paramount 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 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 agua para beber o cocinarse. Si usted está preocupado por el plomo en su agua, usted puede desear hacer probar su 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.

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
