The Proposed Plan to remediate the Contamination

EPA in collaboration with the City of Las Cruces and the County of Doña Ana developed a recommended approach for removing the contamination at the Superfund Site. It is called the Proposed Plan. It has been developed based on the information from the Remedial Investigation and the Feasibility Study and with input from the New Mexico Environmental Department.

Public Meeting on December 7, 2006

To provide the public with an opportunity to comment on the Proposed Plan, a public meeting is scheduled on December 7, 2006. The public meeting will provide the community an opportunity to:

  • Discuss the cleanup alternatives;
  • ask any questions about the proposed plan; and
  • offer formal comments on any of the documents developed for the site. The meeting will be held at:

    Sierra Middle School
    1700 East Spruce
    Las Cruces, NM

    INFORMAL MEET AND GREET:
    6-7:00 PM
    Meeting begins at 7:00pm.
     

  • Comments may also be submitted in writing (letter) or electronically, (e-mail) to Petra Sanchez, EPA Remedial Project Manager, (sanchez.petra@epa.gov) or to Beverly Negri, EPA, Community Involvement Coordinator at (egri.beverly@epa.gov).

The official 30 day public comment period begins on December 4, 2006 and ends on January 5, 2007. The final decisions regarding the remediation of the GWP Site will only be made after public comments are considered.

Site Location

The GWP Site is located in the City of Las Cruces, Dona Ana County, New Mexico. North Solano Avenue to the west; just past I-25 to the east; East Hadley Avenue to the north; and East Griggs Avenue to the south approximately bound the GWP Site. The approximate area of the GWP Site is 0.5 miles by 1.8 miles. (See Map of Area and Estimate of Concentration)

Public Health Issues

The Agency for Toxic Substances and Disease Registry (ATSDR) is the Federal agency created under the Superfund Act that is charged with taking responsive public health actions to prevent harmful exposures and disease related to toxic substances. The ATSDR works in close collaboration with local, state and other federal agencies, with tribal governments, local communities and local health care providers. The goal of ATSDR is to help prevent or reduce the harmful effects of exposure to hazardous substances on human health. The ATSDR finalized a Public Health Assessment (PHA) in February 2005 that reviewed available health-related data for the Griggs and Walnut site. The PHA indicates concentrations of PCE are below levels expected to cause adverse health effects. ATSDR has concluded that the Griggs and Walnut Site presents no apparent public health hazard for past or current PCE exposure resulting from the municipal water supply. The ATSDR report is available at:

Thomas Branigan Memorial Library
200 East Picacho Avenue
Las Cruces, NM 88001
(575) 528-4000

The ATSDR Public Health Assessment is available by clicking the link below. The results of this report are summarized in the (Proposed Plan).

Source of Contamination

The source areas of contamination to the ground water have been identified as historical releases that occurred on City and County property. Given the multiple land use activities that have occurred over time on the properties, the releases were most likely associated with either maintenance activities, or illegal dumping by unidentified parties.
