Fact Check

The items listed on this page cover various claims that have emerged or have been brought to the public’s attention by numerous sources regarding the current hexavalent chromium issue. Each claim is clarified or expanded upon to promote full transparency and understanding. This page will be updated continuously, as new claims emerge or need to be addressed. If you have any questions, please feel free to contact us.

FACT: The Environmental Working Group (EWG) is a national non-profit environmental group whose goal is to convince the Federal Environmental Protection Agency (EPA) to lower the safety thresholds for certain natural and unnatural compounds found in water. As such, EWG has created a database listing what they feel the new standards should be for the safe levels of these compounds. That is where the arsenic figure for Paramount comes from. Many water-quality experts, however, feel EWG’s standards are deeply flawed and unrealistically low, and that current regulations are scientifically based to reflect permissible levels. The City of Paramount’s water supply is tested constantly and continually meets all State and Federal regulations. With arsenic, specifically, California’s Drinking Water Division limits it to 10 parts per billion, and Paramount’s water has less than eight parts per billion. For any questions regarding water quality in the City, please call (562) 220-2020.

FACT: SCAQMD removed monitors in Paramount due to safety issues for their employees related to the pandemic. There is, though, one multi-metal monitor still operating in town that takes hourly readings of many different metals; its data is regularly read remotely by SCAQMD staff. SCAQMD has told the City that recent levels of metals from this monitor have been unremarkable and consistent with average levels observed in 2019/2020.  SCAQMD is hoping to get its employees vaccinated soon but has offered no timeline. The City of Paramount does not feel it has the right to demand how another agency deals with its employees, especially in areas of personal health.

FACT: In regards to Irvine, SCAQMD has explained that the monitoring done there is VERY different than the filter-based monitoring in Paramount. In Irvine, the testing is for volatile organics, a process that does not involve a lot of human contact so their employees do not need to interact very much with one another. In Irvine it is a long-time asphalt plant that is emitting the odors, and in October 2020 the City Council directed their Police Department to explore revoking the company’s business license. An Irvine official recently confirmed to Paramount City staff that, after reviewing the matter with SCAQMD, the City has found it does not have the ability to revoke the business license, and Irvine is now working collaboratively with AQMD to monitor the situation and provide the community with information. This is exactly what happened in Paramount in 2016, and Paramount continues its efforts to contain any ill effects related to these issues.

That information is protected by privacy laws, so the Paramount Unified School District does not have comprehensive data on respiratory or other health issues of its students. Privacy restrictions also limit the comprehensive knowledge of any other organization or person who claims to have broad information about the health status of students at District schools. However, based on observations from nursing professionals who work at PUSD schools, there has been no notable abnormal presence of bloody noses or fatigue among students. For additional information, the District had published significant information on hexavalent chromium and their school facilities here: https://www.paramount.k12.ca.us/apps/pages/index.jsp?uREC_ID=805453&type=d&pREC_ID=1193695

No public health studies have been conducted that indicate an elevated level of risk for Paramount youth. As such, any claims made to that effect are made without evidence. Due to privacy restrictions,Paramount Unified School District has limited access to comprehensive information about the health of its students. However, the District’s nursing and site staff are provided information about the medical needs of their children by the children’s parents. Based upon the information reported by these District professionals, there have been two cases of students with cancer identified by the District, one of them with leukemia.
For additional information, the District had published significant information on hexavalent chromium and their school facilities here: https://www.paramount.k12.ca.us/apps/pages/index.jsp?uREC_ID=805453&type=d&pREC_ID=1193695

Air Quality officials required Carlton Forge to install new enhanced filtration systems and raise the stacks on certain buildings in order to properly disperse pollutants higher into the atmosphere to minimize impacts at ground level. This is a standard best practice adopted by the industry and supported by air quality regulators. Proper dispersion of pollutants results in a reduction of pollution density. Additionally, specific to Hexavalent Chromium pollution, monitor location 25 is located at Lincoln School and has had some of the consistently lowest Hexavalent Chromium levels detected in the monitoring by AQMD. Since February 2017 when that location started to be monitored, the average ng/m3 had been 0.33 and for the period of January 1, 2019 through July 23, 2019 – a period in which levels were measured after action was taken by AQMD to mitigate Hexavalent Chromium emissions – the average is 0.21 ng/m3 at the monitor near Lincoln School. Hexavalent Chromium monitoring continues to take place at Lincoln School every 6 days. For monitoring data, see this link: http://www.aqmd.gov/docs/default-source/compliance/Paramount/expanded-monitoring-data-and-map.pdf?sfvrsn=37 and locate test data for monitor #25

Water Well 13 is not contaminated with cyanide. The latest water quality reports submitted and approved by the State Water Resources Board can be found here and show no measurable cyanide levels: https://paramountenvironment.org/annual-water-quality-reports/

The City performs regular testing of the water system as required by law. Should any negative results come about, the City will (in compliance with the law) inform the community about any negative health effects.

Water Well 13 is not shut down and is still operational, however, it is slated to be taken offline in the near future as part of a long-term strategy for the City’s water supply. The well is being replaced with a newer well that is deeper into the ground and uses newer equipment that is more energy efficient. Water Well 13 has outlived its expected life of 30-40 years and is due for replacement (it has been operating since 1978).

There was a history of manganese being present in the water at Water Well 13, and in 2003 the City implemented a filtration system to address these levels (see City Council presentation from 2003 here). Manganese is not a risk to public health, but it can damage pipes and discolor water. Mitigating the manganese requires the presence of an onsite backwash tank that is prominently located on the Water Well 13 property. There is no diesel fuel on the property or immediately adjacent to Water Well 13.

Water Well 13 testing during 2003 detected arsenic in the water supply, and this concern has been addressed on the website here: https://paramountenvironment.org/ufaqs/claim-paramounts-well-13-is-an-active-well-used-for-drinking-water-and-contains-high-levels-of-arsenic-above-the-environmental-protection-agencys-epa-maximum-contaminant-level-mc/.

True and False.
Hexavalent Chromium levels have dropped off significantly since the AQMD established a network of air monitors and started taking enforcement actions on identified pollution sources in 2016. Extensive data about this progress can be read and seen here: https://paramountenvironment.org/aqmd-updates-paramount-air-monitoring-plan/
Data fluctuates on Hexavalent Chromium emissions, and there were some temporary increased levels detected in May 2019; those levels quickly fell off again. All the data from AQMD can be found here: http://www.aqmd.gov/docs/default-source/compliance/Paramount/expanded-monitoring-data-and-map.pdf?sfvrsn=1246
While the long-term trend is a dramatic reduction in Hexavalent Chromium emissions-detection levels, the City has actively pushed for sustained and ongoing monitoring to ensure public health – including applying for community monitoring under the AQMD’s AB 617 program. This is one reason that the City purchased air monitors and placed them in key locations at the direction of AQMD, so City monitors can sustain monitoring well into the future.

True and False.

Previous testing of soil near Carlton Forge Works in 2014 found concerning levels of various metals and chemicals. Further testing was then conducted in partnership with the Department of Toxic Substances Control and LA County Department of Public Health in 2017. These test results did not find soil contamination. This map shows where soil was sampled in the most recent tests: https://paramountenvironment.org/soil-testing-map/. The process and results of this testing can be found here: https://paramountenvironment.org/soil-reports-test-results/


The City is vigilant about illegal parking issues, and conducts regular patrol checks in all areas of town. Residents have complained about truck parking at Carlton Forge Works (CFW) and the City has issued 41 citations since January of 2018. The City has also met with CFW management to explain City enforcement actions and expectations. This work included suggesting that CFW improve their delivery procedures to minimize the impact on nearby residents. The public is encouraged to report parking violations by calling (562) 220-2002


The City always encourages residents to report any odor-related issues to AQMD, which investigates such reports. Call 1-800-CUT-SMOG

Regarding the effects of hexavalent chromium, upon learning about the significant environmental issues discovered by AQMD, the City partnered with AQMD to aid their investigation into finding the sources. The City also launched a significant public information campaign to keep the community informed about the air quality issues – including launching this website (paramountenvironment.org). Additionally, the City produced video updates for the community, purchased monitors to aid the search for emissions, and spoke at both the LA County Board of Supervisors and the AQMD Board to encourage more action and support for progress on air quality.  Finally, the City formed a sub-committee to investigate the issue from a City viewpoint and advanced and adopted new zoning regulations designed to increase air quality and expand transparency of metal-related companies in the City.



When the South Coast Air Quality Management District (SCAQMD) began their investigation into the elevated levels of hexavalent chromium found by their long-term air quality monitoring efforts, the City of Paramount provided a list of metal-related businesses to assist the District in identifying the source of the carcinogen. Metal-related businesses were defined as: grinding, sanding, plating, electroplating, welding, deburring, heating, heat treating, straightening, forming, machining, cutting, rolling, pressing, forging, fabricating, polishing, milling, swaging, cooling, conversion coating, anodizing, passivation, and spray-coating operations.

This list, taken from Paramount’s permit database, contained 86 facilities located throughout the city. SCAQMD then added businesses of various types to this list of entities so as to inspect all facilities within their jurisdiction. These additions included businesses near Aerocraft Heat Treating and Anaplex Corporation, regardless of whether the business was metal-related, as well as businesses identified by community members who discovered these facilities primarily through Internet searches for metal-related businesses noted to be in the city. Further, the list grew as SCAQMD added facilities by identifying them through permits issued in Paramount for metal-related businesses. As a result of combining all these sources of information, the list of entities to be inspected grew to a total of 194 facilities and businesses. Hence, when SCAQMD states that they had investigated 194 businesses, this means that the District reviewed a list of 194 business entities that had been assembled from several sources and not all of which were metal-related.

Many of these 194 properties/businesses that were reviewed by SCAQMD were found to be either out of business, not located in Paramount, or not involved in metal-related activities. For example, SCAQMD and City Staff determined the following thirteen businesses were no longer operating: Hanks Sheet Metal, JM Metal Polishing, California Precision Deburring, Leavitts Metal Finishing, Luisteel Welding, Western Integrated Materials, Rosenberg Metals, United Sheet Metal, Aluminum Interior Moldings, El Tigre Metal Polish, Best Western Rolling, and E.S. Scales/Somerset Steel.

After extensive investigation, City Staff removed from the list all businesses that were not metal-related, any duplicate listings, and the entities that were no longer operating, listed above. The final number of metal-related facilities licensed to do business in Paramount totals 85, which amounts to 3% of total business licenses issued in the city. Of the 85 businesses, the City and SCAQMD determined that 68 of those businesses do not require SCAQMD permits for metal-related operations (examples include metal dealers, metal screw sales shops, metal supply shops, metal etching companies). To be clear, these businesses may have an SCAQMD permit for a backup generator or other equipment unrelated to metal processing.

The remaining 17 facilities require SCAQMD permits for metal-related processing (as of February 16, 2017).

To summarize: 194 names or locations were added onto a list assembled from multiple sources that was reviewed by SCAQMD; each name or address was investigated. After the investigation was completed, it was determined that there are 85 metal-related businesses in the city limits of Paramount. Of those 85 metal-related businesses, 68 do not require any permits from SCAQMD for metal-related processing. In total, 17 businesses do require SCAQMD permitting for metal-related work.


While the City may have the authority to revoke a business license, it has no legal authority to force a business to close without court action. The City would be required to seek a court injunction to shut down a business. The City would be required to show evidence to the court , such as: high level emissions of hexavalent chromium that are, at least, substantially, coming from that particular business in order for a court to grant the injunction. It is more challenging when a business demonstrates to the court that it is currently taking measures to comply with AQMD’ s abatement order. In December 2016, the LA County Department of Public Health and SCAQMD have already attempted to use the courts to shut down the activities at the Anaplex Corporation facility, and that efforts failed in the courts.

With AQMD’ s Order of Abatement, if these companies are not able to comply and they continue on as “repeat offenders,” the fines associated with shut downs and loss of revenue from being closed, could likely result in these companies closing on their own accord. The City’s hope with SCAQMD’ s regulatory process is that these companies make the necessary changes that results in clean air (i.e., no more illegal emissions) and continued operations and employment for their workers.


The first the City learned about elevated levels of hexavalent chromium was when a reporter called the City seeking comment on a press release from the South Coast Air Quality Management District about elevated levels of hexavalent chromium being detected in the community.

Prior to that, the City had attended and monitored hearings and procedures related to Carlton Forge that started in 2013 and lasted through 2016. At those meetings, SCAQMD presented data on elevated metals in the air and developed a plan with Carlton Forge to address those air quality concerns. In presentations provided by SCAQMD at those meetings, elevated hexavalent chromium levels were never expressed as a significant concern, however they were elevated enough to warrant additional monitoring in the industrial sector of the city. SCAQMD charts showing average hexavalent chromium readings for years 2013, 2014 and 2015 indicated that hexavalent chromium levels near the normal ambient levels of hexavalent chromium in the area (as measured by the SCAQMD monitor in Compton, CA).

Hexavalent Chromium History for Site #2

Hexavalent Chromium History for Site #3

The data on these charts was presented to the City and community at a SCAQMD town hall meeting in August 2016.


Following state and federal guidelines, the City began testing for hexavalent chromium in 2014 and reported the results in the 2014 Consumer Confidence Report available here. To address concerns that hexavalent chromium had contaminated the City’s water supply the City had the water tested again in December 2016 and the presence of hexavalent chromium levels were less than 1 part per billion, a level that is considered healthy. Further, the City has committed to continued testing of hexavalent chromium in the water supply every month for the foreseeable future. The monthly results can be found on the Hexavalent Chromium Test Results page.


The City of Paramount was approached by the Department of Toxic Substances (DTSC) in 2013 to execute soil testing in Village Park. The City, at the direction of the prior city manager, asked the DTSC to first test across the street (in a parkway at the southwest corner of Illinois/Somerset) where the work would be less intrusive than inside the park. The City further instructed DTSC that, should the soil sample be contaminated, the City would work with DTSC to access Village Park for further testing. The City never heard back from DTSC. In 2015, DTSC subsequently requested to test the soil in Village Park and the City agreed to work with DTSC, but first requested that DTSC provide a plan of when, how and who would do the testing, including outlining ownership of any damage done during the testing. The City never heard from DTSC until the issue re-surfaced again at a community meeting in November of 2016. At this meeting, the City immediately agreed to conduct soil testing.


The City has implemented a moratorium on the addition or expansion of metal-related businesses since the City learned about the elevated hexavalent chromium levels found by the the SCAQMD. The City has already denied requests for new or expanding metal-related businesses since the moratorium was put in place. The moratorium was set for an initial 45 day period and expiration on January 24th. The Council extended the moratorium an additional six months and may extend the moratorium up to a total of two years. Certain exceptions in the extended moratorium allow for improvements at existing businesses that will enhance air quality or are non-production related improvements (examples: security, employee break areas, parking lot improvements).


The City of Paramount does not issue permits specific to metal businesses. The City issues business licenses as part of its normal business licensing process. The City’s business issuance process for new businesses includes a self-identification process for the business to review their requirements to seek air quality permits from the SCAQMD. Businesses that self-identify as requiring SCAQMD permits must then contact SCAQMD to apply for those permits. The City is reviewing this process with SCAQMD to determine methods more effective than self-identification. Any new process will apply to new business license applicants. Also, it should be noted that the two businesses that have been identified by SCAQMD as the main sources of high hexavalent chromium emissions have had air quality permits from the SCAQMD for a several years.

While business licensing is a tool that can be leveraged to engage more SCAQMD oversight, the City’s land use policy determines whether the type of business is even acceptable on the property on which it will operate. Hence, a business that seeks to operate a metal-related business in the City’s M-2 manufacturing zone has a right to open that business under current land use rules in the City. The City does not limit a specific number of businesses that are metal-related in the City.

Update 9/14/17: In June 2017, the City of Paramount launched a pilot program to enhance air quality compliance in the city by submitting selected business license applications and business license renewals to the SCAQMD. The pilot program, the first of its kind in the SCAQMD territory, is a significant expansion over the existing review process that SCAQMD provides to cities.

Under the pilot program, specified categories of businesses (those that could potentially require an air quality permit) need to show proof that they have been cleared to do business by SCAQMD to receive City approval. Then, in those same categories, the City will deliver renewal applications to SCAQMD for the District’s review and determination if the business needs a new or modified SCAQMD permit.


The City does not have jurisdiction over the Paramount Unified School District (PUSD). The District is its own legal entity with its own controls and authority. Further, school district lands across California are subject to control and oversight of the State of California, Division of State Architect and not the City. The City does not have authority to require or dictate how and what the Paramount Unified School District does with their land or buildings.

The City has encouraged SCAQMD to install air monitors at the schools in Paramount Unified School District, and the Schools have allowed that to happen. The monitors will be eventually used at each campus to test the air. Results of the testing can be found on the SCAQMD website here.

Further, a PUSD representative is participating in the Air Quality Sub Committee and providing perspective and insights from PUSD.


City council members and city staff have attended nearly every meeting held by SCAQMD in relation to air quality concerns in the City since the first town hall meeting on the matter in 2016. Meetings that have had council members or city staff representation include:

  • SCAQMD Town Hall Meeting on August 16, 2016

There is a provision in the State Health and Safety Code that confirms the authority and function of South Coast Air Quality Management District (SCAQMD) with respect to air quality regulation, but also purports to allow any regulated agency within the SCAQMD to apply stricter air quality regulations than SCAQMD; provided those regulations are not in conflict with SCAQMD regulations.

The provision falls under section 40449 and reads as follows:

§ 40449. Cities or counties; adoption of ordinances stricter than district rules and regulations; assistance of district
(a) No provision of this chapter is a limitation on the power of any city or county included, in whole or in part, within the south coast district to adopt any ordinance with respect to air pollution control which is stricter than the rules and regulations adopted by the south coast district board and not in conflict therewith. The south coast district board shall enforce any such ordinance.
(b) At the request of the governing body of any city or county included, in whole or in part, within the south coast district, the south coast district board may make available, on a temporary basis, the necessary personnel, equipment, and services to assist in adopting any ordinance stricter than the rules and regulations adopted by the south coast district.

The Paramount City Attorney inquired of other city attorneys representing cities within the SCAQMD and found that this section of state law has not been implemented in other cities. In addition, the City has asked both TetraTech – one of the largest environmental consulting firms in the world and SCAQMD – the most advanced and knowledgeable air quality agency in the world – to find out whether other cities have used this authority. Neither could identify a city or county that has used this provision to develop their own air quality regulations.

The City has consulted with its environmental consultants, TetraTech, about their opinion of the City adopting more stringent standards than SCAQMD, and they have raised a number concerns for the City to consider. First, no matter what standards are developed for air quality, the City must be prepared to not only establish scientific data to support that standard, but also successfully defend the data in the event the data is challenged as being arbitrary. Science is costly. Lawsuits are costly. If the City creates an arbitrarily low standard that is not supported by scientific data, the City risks costly litigation as well as the City having to pay for attorney’s fees of the other party should it lose. As a City, Paramount lacks the experience, expertise and long term resources to regulate air quality as effectively as SCAQMD does.

Creating regulations supported with sound scientific data is an area where SCAQMD has clear advantages. Consider a comparison of the staff size and budget of SCAQMD with 813 staff and $141M budget to the City of Paramount’s 91 staff and a $43M budget, Paramount is dwarfed by SCAQMD’s budget and expertise. Consider also that SCAQMD has scientists, attorneys and engineers who only focus on air quality.


The raw, untreated water at Well 13 does register levels of arsenic that border or exceed the EPA’s MCL for the compound. However, the water produced at Well 13 goes through the water treatment plant located at this well. This process removes arsenic, along with manganese, to meet all State and Federal Drinking Water Standards, as stated in the City’s Water Consumer Report. Further, the water is disinfected through chlorination, which is the case for all water either produced by the City’s water utility or is imported through the Metropolitan Water District.


The City of Paramount has its water tested by independent labs on a regular basis to make sure there are no impurities or dangerous levels of contaminants in the supply delivered to consumers. One component that is looked at monthly is the presence of arsenic.

The United States Environmental Protection Agency (EPA) has established a maximum contamination level (MCL) for arsenic of 10 ppb. Amounts of the chemical above this are considered unsafe for drinking, while levels below are considered safe.

In its raw, naturally occurring state, the water pumped from the ground at Well #13 does, on average, have an amount of arsenic that exceeds the EPA’s maximum contamination level. However, that water is treated and cleansed – like all water in the Paramount system – so what residents receive has insignificant traces of arsenic well within the safe levels as determined by the EPA.

The State of California checks on the quality of Paramount’s water. If they found unsafe levels or any chemical, including arsenic, they would shut our water utility down.

That has never happened in Paramount.

It was recently posted on social media that Paramount’s water exceeded the MCL for arsenic in 2008 and 2009 as described in the City’s Consumer Confidence Reports for those years. That posting chose to ignore a footnote in the CCR that stated: “While your drinking water meets the federal and state standard for arsenic, it does contain low levels of arsenic. … For this well system, the filtration treatment technique is used to remove arsenic and manganese from the water prior to distribution. Water after treatment is in compliance and below the MCL.”

One of the City’s most important and serious duties is providing safe, clean water to its residents. That will never change; Paramount’s water has always been, and will continue to be, completely safe for any use.


According to the South Coast Air Quality Management District (SCAQMD), the sample for Site #19 on May 1st was not collected: it was used for an off-schedule sample that was collected on May 3rd. Due to the off-schedule sample on May 3rd, the typical May 4th sample was not collected. The normal schedule for sampling will resume on May 7th. SCAQMD is preparing another sampler so they do not have to alter the schedule for Site #19 to collect on off-schedule sample in the future.

Additionally, the portable City samplers should not have been marked on the ambient data spreadsheet. They will be removed, as the City monitor would not have been at Site #19 after the initial sample. The portable samplers are being implemented into the rotation of SCAQMD samplers. The agency will clarify this on their Expanded Monitoring Data and Map spreadsheet.


When Paramount was incorporated as a city in 1957, it inherited land uses that the County of Los Angeles had put in place. All of the industrial zones in Paramount predate the City’s incorporation. Since then, the City has worked to continue making land use and zoning changes to remove many blighted and industrial uses. For example, when The Home Depot was added, this replaced a large swath of industrial property with commercial retail space. In addition, the City has worked to ensure that various uses match the appropriate zone. Since 1963, no new housing has been allowed to be built in the City’s core industrial area.


Tetra Tech provided the following response to the City regarding this accusation:

“Tetra Tech has never been tried or convicted of falsifying soil samples. The allegations made on recent newscasts are unsubstantiated and there is no evidence to support the accusations.

“When sample results at the Hunters Point Naval Shipyard appeared not to be representative at the site, Tetra Tech immediately investigated and reported its findings and corrective actions to the Navy and Nuclear Regulatory Commission. No restriction, suspension or qualification of any license, certification, or registration occurred, and Tetra Tech’s NRC Radioactive Material License is in full good standing.”


The City of Paramount and Carlton Forge Works, through an open and public process, entered into an agreement for a land exchange in 2005 that allowed for better land use for both City and company.

The Paramount City Council held a public hearing to vacate the portion of Adams Street south of Somerset Boulevard and between Colorado Avenue and Vermont Avenue. Because Carlton Forge Works owned the land on both sides of the area that would be vacated, it was determined that this portion of Adams Street was not useful to the public for street access. Carlton Forge Works would then be able to convert the vacated area into a parking lot for its employees, thus removing cars from taking up street parking in the surrounding neighborhood.

In exchange, Carlton Forge Works gave the City a piece of property on Vermont Avenue, which the City used to create a vital element of water infrastructure that to this day helps ensure a safe and reliable supply of water to Paramount residents.

(As a side note, the City consistently tests its water supply, the results of which show that Paramount’s water meets all federal and state standards. In fact, the City has actually increased the frequency of testing over and above federal and state standards. Test results are available here: https://paramountenvironment.org/hexavalent-chromium-test-results/)

In 1996, the Paramount Planning Commission examined the idea of a transferring a plot of land, less than one acre, on Ohio Avenue to Carlton Forge, who was asking to expand onto the land, which was adjacent to its facility.

“Ohio Park,” as the area was called, was located north of Jefferson Street and south of Adams Street, and very close to nearby Village Park. It had previously been an unused street that was converted to an unimproved green space with no park amenities.

The City conceived a plan that would create a new park in another part of town, a densely populated area that was lacking open space, with the funding coming from Carlton Forge Works. Consequently, the City Council voted to vacate the Ohio property, turn it over to the company, and Carlton Forge Works then paid $256,000 to the City for land acquisition.

As a result, the City developed Garfield Park, located on the corner of Garfield Avenue and Petrol Street, thus providing a better distribution in town of walkable park space for residents.

At that time, SCAQMD was investigating only Carlton Forge Works, and for elevated levels of nickel and cadmium. The City was kept informed of that investigation. In the summer of 2016, SCAQMD did present data to the City and the community-at-large of hexavalent chromium readings that were above background levels around Carlton Forge but expressed no immediate concerns about this information. Never during this time did SCAQMD identify Aerocraft or Press Forge as being responsible for elevated levels of hexavalent chromium. SCAQMD also presented a plan to expand their air monitoring to other parts of the industrial sector, leading the City to hire a consultant to help staff understand the science behind the investigation. SCAQMD then discovered very high levels of hexavalent chromium in late October 2016. This was the first time the City learned about these very high levels. In late November of 2016, SCAQMD identified Aerocraft as one source of these levels and began its process of forcing the company to comply with air quality regulations and laws.
