Comment Period

Warden City Water Supply Wells 4 & 5

Public comment period

Feb. 3, 2020 - March 4, 2020, 11:59 p.m.

We invite you to comment on plans to clean up the Warden City Water Supply Wells 4 & 5 site.

The Warden City Water Supply Wells 4 & 5 site is located on the 1900 block of W. First Street in Warden.

The following draft documents are available for comment:


From 1971 to 1992, Simplot stored, blended, and transported agricultural chemicals, including the pesticide EDB, at the site. The proposed plan is to excavate contaminated soil, treat it onsite, and backfill the excavation with treated, clean soil. Groundwater will be monitored semi-annually to confirm contamination is reducing following the removal of contaminated soil.

Public comment process

We will consider and respond to all comments received during the comment period. If the documents change substantially based on public comments, we will hold another comment period. If not, the documents will be final and cleanup will proceed. We will hold a public meeting if 10 people request it.
