  • Frequently Asked Questions: Additional information about Test Results for Swimming Pool Water at Edison High School

    The City of Huntington Beach contracted with Sierra Analytical—an environmental laboratory certified by the Department of Health Services—to test the swimming pool water at Edison High School in June 2019. Those testing results can be found at https://www.hbuhsd.edu/apps/pages/ascon-landfill

    Based on the Ascon project’s review of the City of Huntington Beach’s testing results, we’re responding to questions from community members. We provided a response to an earlier question on October 9 (scroll to that date on Project Updates). Below are additional questions we’ve received.

    Where does southeast Huntington Beach drinking water come from?

    The City of Huntington Beach provides drinking water to residents from both municipal groundwater wells and from imported water provided by the Metropolitan Water District. This is the water used in the Edison High School swimming pool. There are no drinking water wells in southeast Huntington Beach due to seawater intrusion into groundwater aquifers.

    I noticed other chemicals listed on the Edison High School swimming pool test results. What do the results for hexavalent chromium mean?

    The amount of hexavalent chromium reported in June 2019 was 0.96 micrograms per liter (ug/L), which is less than 1 part per billion (ppb). This amount is below the California Drinking Water Standard for total chromium of 50 parts per billion and also is below the federal Environmental Protection Agency (EPA) standard of 100 parts per billion for total chromium.

    Total chromium includes all forms of chromium, including chromium-6 (hexavalent chromium). You can read more about this from EPA at https://www.epa.gov/dwstandardsregulations/chromium-drinking-water

    What about the other chemicals detected in the pool water?

    Three other chemicals—chloroform, bromodichloromethane and dibromochloromethane—were reported as detected in the pool water at levels below the California Safe Drinking Water Standard or Maximum Contaminant Level (MCL). These are three of the four regulated trihalomethanes (THMs) typically found in drinking water as a result of adding chlorine or some type of disinfection. The fourth regulated trihalomethane is bromoform, which was not found in the pool water.

    Trihalomethanes are “disinfection byproducts” resulting from the addition of chlorine or other disinfectants to drinking water and also to swimming pools. The Safe Drinking Water Standard or California Maximum Contaminant Level (MCL) for total trihalomethanes is 80 micrograms per liter (ug/L) or parts per billion (ppb). Trihalomethanes are required to be reported as the combined total concentration of the four regulated chemicals.

    • The chloroform concentration was 13.2 micrograms per liter (ug/L or ppb)
    • The bromodichloromethane concentration was 4.56 micrograms per liter (ug/L or ppb)
    • The dibromochloromethane concentration was 1.40 micrograms per liter (ug/L or ppb)
    • Bromoform was not detected in the pool

    The combined total concentration of the four regulated trihalomethanes reported in June 2019—including bromoform, the chemical that was not found—was 19.16 micrograms per liter (ug/L ) or parts per billion (ppb). This is well below the California MCL of 80 micrograms per liter (ug/L) or parts per billion (ppb).

    More about chlorination:

    Almost all community water systems in California—including Huntington Beach—use some type of chlorine-based disinfection method to prevent microbial waterborne disease epidemics, such as typhoid and cholera. Disinfection of community water systems also prevents growth of slime bacteria, molds and algae. Community water systems are required by federal law to ensure adequate disinfection so that a residual of the disinfectant is present throughout a water distribution system to protect public health.

    The City of Huntington Beach provides more information about disinfectants and disinfection byproducts on page four of their annual Drinking Water Quality Report for 2019 at https://www.huntingtonbeachca.gov/2019dwqr/2019-water-quality-report.pdf

  • AES continues test firing gas turbines at new energy facility

    AES LA Times 2019 Rendering of new AES Huntington Beach Energy Project near Ascon. (Image courtesy of AES)

    The new AES power plant near Newland Street and Pacific Coast Highway southwest of Ascon continues to test fire the gas turbines for the new Huntington Beach Energy Project. The test firing started on October 3. The first unit has completed the Steam Blow phase and the second unit will begin initiating “first fire”. Both units will be tested concurrently after the second unit completes test firing.

    This is a visible activity for the power plant in southeast Huntington Beach—with noise and odor—and not associated with Ascon.

    Update from AES: During this process, natural gas is combusted in the gas turbines to produce high pressure steam which cleans the main lines/pipes.

    Noise: The Steam Blow phase can last from about one to two weeks. Steam blows can be expected 24-hours per day, with open air Steam Blows intermittently between the hours of 8 a.m. and 6 p.m. AES reports a loud hissing sound will be heard during open air Steam Blows.

    Yellow/Light Orange Plume: AES reports the yellow/light orange plume vented from the new stack is part of the commissioning process and is due to “oxides of nitrogen”.

    More information about this activity at AES is available at www.RenewAESHuntington.com. The AES hotline is (888) 372-5633.

  • Frequently Asked Questions: Test Results for Swimming Pool Water at Edison High School

    Did they find benzene in the swimming pool water at Edison High School?

    No, benzene was not detected in the pool water at Edison High School. Benzene is listed as a Laboratory Control Sample (LCS) on the test results.

    What is a Laboratory Control Sample?

    A Laboratory Control Sample is used as part of the laboratory quality control procedures to assure testing is properly performed and that test results are reliable. Chemicals in defined amounts are included in the LCS to confirm the testing equipment is working properly. The chemicals used in the LCS are prepared and certified by an accredited outside agency.

    The laboratory that conducted the test of the swimming pool water for the City of Huntington Beach used the EPA 500 Series Method, a method designed to identify and quantify organic compounds in municipal drinking water in compliance with the Safe Drinking Water Act.

    Are there chemicals in the pool water that exceed safe levels?

    The testing conducted by Sierra Analytical—an environmental laboratory certified by the Department of Health Services—found no chemicals that exceeded drinking water standards. Drinking water standards are known as Maximum Contaminant Levels (MCLs) and listed in Title 22 of the California Code of Regulations.

  • AES begins “first fire” on Thursday, October 3

    AES LA Times 2019 Rendering of new AES Huntington Beach Energy Project near Ascon. (Image courtesy of AES)

    The new AES power plant near Newland Street and Pacific Coast Highway southwest of Ascon expects to start up the gas turbines for the new Huntington Beach Energy Project on Thursday, October 3. This is a visible activity for the power plant and not associated with Ascon.

    AES explains: “During ‘first fire’, natural gas is combined with air and ignited through a combustion process to rotate the gas turbines. The heat generated from this process is used to convert water into high pressure steam. Following a successful first fire, high pressure steam will be used to thoroughly clean the plant steam pipes to avoid damage to the steam turbine. During the Steam Blow process, steam will be released from a temporary pipe and vented to the atmosphere. This will create a large steam plume that will be visible for the duration of each steam blow.”

    The new AES facility’s steam blows may be expected between 8 a.m. and 6 p.m. AES has provided more information about the Huntington Beach Energy Project commissioning and start up at http://www.renewaeshuntington.com/HBEP%20Commissioning%20and%20Start%20Up%20FAQ_rev8.pdf

    Final Remedy Barrier Fence Graphic, Sep 16, 2019

  • Barrier Fence

    Construction of the 16-foot fence along Hamilton Avenue is nearing completion. Next week, the fence installation continues on Magnolia Street over the next couple of weeks.

    Frequently Asked Questions about the fence:

    Why does the fence look like it is being installed backwards?
    The fence is being constructed with the fabric panels facing inward per the permit requirements with the City of Huntington Beach, which define both the building and traffic safety design elements.

    Why aren't you installing the fence at the corner, near the intersection of Hamilton Avenue and Magnolia Street?
    We will be installing the fence at the intersection corner after the official restart of remedial work at Ascon. This is due to the limited space between the edge of the landfill and the intersection signal, which will require some excavation to allow placement of the concrete base and fence panel installation.

    Are the lane closures permanent?
    No, it is not permanent. The lane adjustment on Hamilton Avenue and the bike and vehicle lane closure on Magnolia Street between 9 am to 3 pm is temporary and only during the construction of the fence. Pedestrian access next to Ascon will remain closed during the remainder of the final cleanup.

    When do you expect to be done constructing the fence?
    We anticipate the major sections of the fence along Hamilton Avenue and Magnolia Street to be completed by the end of September. The northeast corner will be constructed after the official restart of remedial work, which will occur after a community meeting. The corner fence construction is expected to occur over a two to three week period at that time.

  • DTSC Statement Regarding Progress Made in Implementing Health and Safety Enhancements at Ascon Landfill

    On July 9, 2019, representatives of the Responsible Parties cleaning up the Ascon Landfill site in Huntington Beach briefed officials on the implementation of health and safety enhancements at the site. The Department of Toxic Substances Control (DTSC) suspended cleanup activities at the site after community members lodged hundreds of odor complaints. Work will resume once the Responsible Parties implement the health and safety enhancements required by DTSC. (DTSC’s letter describing the enhancements is attached.)

    Officials in attendance included Huntington Beach Mayor Erik Peterson, other city officials, Assemblymember Cottie Petri-Norris’ staff members, Huntington Beach City School District and Huntington Beach Union High School District administrators, DTSC and South Coast Air Quality Management District (AQMD).

    The representatives described enhancements they have completed, and enhancements in the process of being implemented or designed. They are already using more effective odor suppressants on contaminated, bare soil. They and AQMD staff have sampled onsite concrete rubble for asbestos and found none. They have increased the on-site monitoring frequency to 24 hours a day, seven days a week for chemicals that might travel through the air in dust or vapor.

    The representatives have also committed to expand their air monitoring network to include mobile stations at Edison High School, Eader Elementary School, Edison Community Park and on two residential streets by September 30, 2019.

    Ongoing air monitoring at the site has not found any chemicals above levels that present a public health concern. The health protective monitoring levels are set to protect members of the community, including children and other vulnerable people.

    The representatives will meet with DTSC, AQMD and other oversight agencies on July 16, 2019, to discuss their proposed actions to implement other enhancements. DTSC and other officials asked the representatives to provide timelines for implementing required enhancements.

    At the request of officials for the city of Huntington Beach, members of the government organizations at the briefing agreed to participate in two teams. One team will focus on coordinating government agencies to facilitate implementation of health and safety enhancements. The other team will help the representatives provide community information on the actions the representatives are taking to implement the enhancements.

    For additional information: Members of the community may contact DTSC Public Participation Specialist Stacey Lear at (714) 484-5354 or Stacey.Lear@dtsc.ca.gov.

    A new product is being used at the Ascon Landfill Site to cover some of the excavated areas of the Site as an additional mitigation measure for potential odor and dust. Posi-Shell® is a medium to dark clay color when applied and lightens in color as it dries. This product is slightly darker in appearance than the non-toxic white Rusmar foam used as an odor suppressant at Ascon.

    Posi-Shell® is a non-toxic blend of bentonite clay, fibers, and polymers which dries as a thin stucco. It is applied as a wet slurry using equipment similar to hydro seed equipment.

  • Update from the Ascon Landfill Site Project Team

    The Ascon Landfill Site project has implemented a temporary shutdown of excavation activities to establish enhanced mitigation measures, in compliance with direction from the lead regulatory agency, the California Department of Toxic Substances Control (DTSC).

    DTSC states that “monitoring has not found any chemicals in the air above a level that causes public health concern.” The enhanced mitigation actions being implemented address odor concerns and help answer questions from the community about the final cleanup.

    The Ascon Landfill Site team takes public concerns very seriously. We support actions that maintain a safe environmental cleanup and we support actions that help the public better understand the work being conducted.

    A temporary shutdown of excavation activities was announced by the Ascon project on Thursday, June 6, 2019, until the end of the school year for Edison High School, as well as the construction during the shutdown of a taller barrier fence along Magnolia and Hamilton streets, and support and funding of a third-party technical advisor. DTSC extended the temporary shutdown to allow time to implement enhanced mitigation actions during the final cleanup of the 81-year-old Ascon Landfill Site.

    The Ascon project team will work with DTSC, the City of Huntington Beach, South Coast Air Quality Management District (SCAQMD) and the Huntington Beach Unified High School District (HBUHSD) regarding actions directed by DTSC on June 12, 2019, which include:

    • Construction during the shutdown of the taller barrier fence along Magnolia and Hamilton streets announced by the project team on June 6.
    • Establishment of a third-party technical advisor, under the management of the City of Huntington Beach.
    • Investigation of the feasibility of additional tenting or enclosure in excavation areas that have potential to produce more odors.
    • Cover or solidify impacted soil in excavation areas, in addition to mitigation measures already conducted.
    • Monitoring of additional heavy metals, in addition to metals currently included in the air monitoring program.
    • Additional offsite air quality monitoring, including at nearby schools, and a review of air quality monitoring validation methodologies which confirm monitoring data.
    • Analysis of onsite concrete to address community concerns regarding potential asbestos.
    • A complaint and response protocol, to formalize DTSC and project team actions already implemented in response to community concerns.

    Some actions are already in progress, such as construction of the taller barrier fence during the shutdown. Some require additional development with the DTSC technical team, prior to specific details being available. During the shutdown, field actions including air quality monitoring, dust and odor mitigation, regular site inspection, and 24-hour site security will be conducted. There also will be delivery of equipment required for future cleanup work activities and activity regarding additional analysis of onsite materials.

    While the Ascon project team is working to implement these actions, it is anticipated the shutdown will remain in place for at least 30 days. Updates on the current actions and the status of the final cleanup will be posted when available on the project website, www.AsconHB.com.

  • Field work at the Ascon Landfill Site during the week of June 10 is planned to include:

    • Preparation for installation of taller barrier fence along Hamilton Avenue and Magnolia Street, with construction anticipated to begin subject to City of Huntington Beach permit approval.
    • Dust and odor mitigation measures will continue to be implemented.
    • Active measures will continue to be taken to monitor air quality.
    • 24-hour onsite security will continue.
  • There will be a temporary shutdown of field activities at the Ascon Landfill Site. The project team will announce when field activities are expected to resume, with concurrence by the Department of Toxic Substances Control (DTSC).

    The Ascon Landfill Site project team announced on June 3 the construction of a taller barrier fence, which we anticipate should begin being installed the week of June 10, subject to City permits. Ascon Landfill Site also previously announced a temporary shut down through the end of the school year in June for Edison High School.

    During this time, there will be a continued presence onsite to conduct dust and odor measures, site security and site maintenance. We expect the taller barrier fence construction, as well as the establishment of a third party technical advisor. The project team fully supports a third party technical advisor for the community to help the public better understand the project and field actions.

    The Ascon Landfill Site team takes the public concerns very seriously. We support actions that maintain a safe environmental cleanup and we support actions that help the public better understand the work being conducted.
