Water Treatment Improvements in Lordsburg, New Mexico.

Status: Completed Construction

Background

The water supply existing in the City of Lordsburg had fluoride levels that exceeds the Maximum Contaminant Level (MCL) of 4 mg/L; a primary water quality standard. The October 2004 water quality results measured a concentration of 5.02 mg/L of Fluoride at the Entry Point (Well No.1, Well No.2, SP Well) and 12.52 mg/L of Fluoride at the Smith Well. The project was selected for funding based on a publication describing high incidence rates of fluorosis and skeletal fluorosis documented in the community. The implementation of the Water Treatment Improvements will provide benefits including the reduction of fluoride in the city's water, improve the water treatment system, comply with the regulatory requirements, and improve the health of the community.

Description

The purpose of the project was to improve water quality through the implementation of an activated alumina treatment system, which contributes to the reduction of the risk of waterborne diseases associated with high levels of fluoride.

Benefits

The project consists of improvements to the drinking water treatment system to reduce fluoride concentrations from water for the community of Lordsburg, New Mexico.
