Q & A


Q: What is the Roosevelt Irrigation District?
A: The Roosevelt Irrigation District (RID) was formed in 1927 to serve customers in the West Phoenix area. The District uses 50 miles of main canals and 185 miles of lateral canals to deliver water for beneficial use.

Q: What is the West Valley Groundwater Clean-Up Coalition?
A: The Coalition is a group of organizations and businesses who voluntarily commit to participate in the groundwater clean-up project.

Q: Where is the contaminated water located?
A: The contamination is generally located at the West Van Buren WQARF site, which is bordered on the North by McDowell Road; by Buckeye and Lower Buckeye Road on the South; 7th Avenue on the East and 79th Avenue on the West.

Q: What caused the contamination?
A: The introduction of industrial chemicals trichloroethene, cis-1,2-dichloroethene, tetrachloroethene, 1,1-dichloroethene, 1-dichloroethane into the soil and groundwater, as well as petroleum hydrocarbons and MTBE.

Q: Why do we need a comprehensive cleanup plan?
A: As long as contaminants remain in the associated groundwater aquifers, a potential threat to public health exists. Equally important: Water is a precious resource in the desert. Until this valuable resource in the WVBA is adequately treated, it cannot be safely made available to the Valley's growing population.

Q: How much will this cleanup cost?
A: Preliminary estimates for the total cost of the cleanup could be up to $200 million during the first 30 years.

Q: Who is going to pay for the cleanup?
A: 100 entities – corporate, governmental and private – have been identified as potential contributors to the groundwater contamination. Each of these Potentially Responsible Parties (PRPs) will be asked to step up and bear the burden of restoring this valuable resource to citizens of the Valley.

Q: Who are these PRPs?
A: Because of potential legal implications, we are not prepared to name the parties at this time. However, PRPs were identified using ADEQ and EPA documents. PRPs may choose to identify themselves as participants of this Coalition and demonstrate their intent to work together to cleanup the contamination.

Q: What happens if these PRPs refuse to cooperate?
A: In that case, RID is prepared to litigate in court to require PRPs to cleanup the contamination.
