Document Description
The proposed project consists of construction facilities for the extraction and treatment of perchlorate from the City of Monterey Park's (City's) Well 12 and proposed Well 15, and for the extraction and treatment of volatile organic compounds (VOC's) for the City's Wells 1, 3 and 10, to be located at the City's existing Delta Pumping Plant located at 3657 N. Delta Avenue, in the City of Rosemead, as shown in Figure 1. The proposed project is sometimes referred to herein as the Delta Treatment Plant. It is located in the western portion of the South El Monte Operable Unit (SEMOU), which is a subunit of the San Gabriel Superfund Site established by the United States Environmental Protection Agency (EPA). Multiple areas of the San Gabriel Basin aquifer are contaminated with VOCs, as well as other chemicals including Nitrate, Perchlorate, N-Nitrosodimethylamine (NDMA), and 1,4-Dioxane. These chemicals of concern continue to migrate in a westerly direction within the deeper aquifer of the SEMOU and have affected numerous water purveyors in the SEMOU. The proposed project meets EPA's objectives of containment, capture and removal of contaminants for the SEMOU and provides a potable water supply for the City whose water supply wells have been impacted by contamination.
