Project Info

Title

Explorer Well Project

Description

The Project involves construction of a new groundwater production well and its connection to the Monk Hill Water Treatment Plant (MHWTP) to optimize removal of perchlorate and VOCs from what is referred to as the “mid-plume” area of contamination in the underlying aquifer. The Project includes a new well, an 800-foot segment of raw water pipeline, and outlet pipes to existing basins. The Project site is in the City of Pasadena on land owned by the City in the Hahamongna Watershed of the Arroyo Seco, a 24.9-mile-long tributary to the Los Angeles River. The Project site is located approximately 200 feet east of the Arroyo Seco, approximately 215 feet west of properties that are within unincorporated Los Angeles County, and approximately 520 feet east of the JPL property, which is located at 3800 Oak Grove Drive in Pasadena. The Project site is located on and near the former JPL East Parking Lot.
