DID YOU KNOW
The Ascon Site has no impact on drinking water. All impacts to groundwater are contained within/beneath the Site in a shallow zone not considered part of the groundwater basin. Additionally, due to seawater intrusion into the groundwater basin, there are no drinking water production wells within three miles of the Site. The Orange County Water District (OCWD) manages the 316-square mile groundwater basin and operates “injection wells” using treated water to create an underground seawater barrier along Ellis Avenue in Huntington Beach extending into Fountain Valley. You can learn more about the Orange County groundwater basin and the seawater barrier here. You can view the latest Huntington Beach Water Quality Report and see frequently asked questions on this City webpage. Learn more about groundwater monitoring at the Ascon Site here.

DRONES: The community is asked to not fly drones over the Ascon when there is active work. This could create worker and Site safety issues. We appreciate the community’s assistance by preventing drone flights over sensitive onsite equipment and the power lines along the perimeter of Ascon.
ENTRANCE AND EXIT GATES: Entering the Ascon site is prohibited to those who are not authorized. The community is asked to keep a safe distance from both entrance and exit gates at Ascon, and refrain from parking, walking, or standing in these areas. The gates on Magnolia Street and Hamilton Avenue may open unexpectedly for workers conducting air monitoring and site inspections, as well as supply delivery and removal.
PEDESTRIANS: Your safety is important! Pedestrians have been observed walking next to Ascon along Magnolia and Hamilton streets next to the concrete fence base where there currently is no sidewalk. We encourage pedestrians to observe public pathway signage and use the sidewalks on the east side of Magnolia and the north side of Hamilton.
PHYSICAL DISTANCING: Work at Ascon is being conducted under Site safety protocols regarding COVID-19 and ongoing protocols and procedures to maintain job safety. 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.
