Field work at the Ascon Landfill Site during the week of September 7:
SITEWIDE: 24-hour onsite security continues. Security may not be visible at the entrance gates. The Ascon security personnel are primarily within the Site conducting daytime and nighttime patrols of the 38-acre property. In addition to 24/7 onsite security, there are regular visits by air quality technicians, site inspectors, and site maintenance personnel.
SAFETY MESSAGE: Work at Ascon is being conducted under Site safety protocols regarding COVID-19. These practices apply to air quality professionals and other team members who may be outside the fence conducting work. We ask for the community’s support of these safety practices by maintaining physical distancing to allow these professionals to focus on their work and stay safe.
AIR MONITORING: Air monitoring was paused over the Labor Day holiday weekend beginning 7 am Friday, September 4, and resumes at 7 am, Tuesday, September 8. DTSC authorized Ascon to temporarily modify the air monitoring schedule to allow air quality professionals time with their families.
For more information about Ascon’s air monitoring and data sharing, please visit Actively Monitoring Air Quality on this website. Data are submitted to DTSC and shared on their online document archive, Envirostor.

GROUNDWATER: Groundwater at the Ascon property has been monitored as far back as 1982, when the landfill was still operational. Monitoring is conducted by collecting groundwater samples from wells located offsite in the surrounding neighborhood. Impacts from the former landfill to shallow groundwater—a saturated zone and not a potable aquifer—are found to be contained within the Site boundaries. All drinking water wells in Huntington Beach are at least three miles from Ascon. Long-term groundwater monitoring will continue after the cleanup, using both existing offsite monitoring wells and new replacement onsite wells. Learn more about Groundwater Monitoring at Ascon.
SITEWIDE: Regular inspections are conducted by Orange County Mosquito and Vector Control District of the onsite detention basins and other areas of the Ascon site where water may be detained. These inspections typically are conducted monthly. Active mitigation measures by Vector Control are protective of the community, as well as onsite workers, to prevent mosquitoes and other pests. The most recent inspection by Vector Control was Wednesday, September 2.
SITEWIDE: Stormwater management is subject to inspection by the City stormwater inspector. Ascon conducts stormwater inspections in advance of forecasted rain as an ongoing essential activity. There is continued inspection and maintenance of stormwater management measures to maintain compliance with Ascon’s stormwater permit. Current activity includes planning sitewide actions that will be taken prior to the rainy season.
