PWAV Site Characterization Drilling Program (MW-1 and IW-1), and Drilling, Construction, Development and Testing of Well 37

The work to be performed under this Contract consists of furnishing all labor, equipment, materials, and forces necessary for the drilling, construction, development and testing of one (1) monitoring well, designated MW-1, one (1) full-scale injection well, designated IW-1, and one (1) municipal water supply well, designated Well 37. The monitoring and injection wells are part of a site characterization drilling program in support of the Palmdale Water District (PWD) Pure Water Antelope Valley (PWAV) project. The primary goal of the PWAV project is to develop a drought-resilient water supply for the Antelope Valley area through replenishment of the groundwater basin by injection of treated wastewater. The primary goal of the site characterization program is to refine understanding of area aquifers from which an existing groundwater model can be validated and refined to confirm regulatory compliance. Among other things, this proposed program will include installation and testing of an injection well and hydraulically downgradient monitoring well to better characterize the subsurface lithology and geochemistry, estimate potential full-scale injection capacity, and estimate aquifer transport properties.

The Palmdale Irrigation District was formed in 1918 under the provisions of Division 11 of the Water Code of the State of California to supply irrigation water to the approximately 4,500 acres of agricultural land within its boundaries. Under this Code, the District’s primary functions were, and continue to be, to acquire, control, conserve, store, and distribute water for the beneficial use of inhabitants and water users within the District.

The Palmdale Water District (District) is an independent special district governed by a five-member Board of Directors who serve the public by division. Special districts provide accountability and a means to vote selectively and provide customers the opportunity to express their preferences more precisely. The most basic virtue of a special district is to allow citizens to customize government to suit their needs.
