About the Project

After nearly seven months of construction, the filter at Well 29 began operating on April 15, 2009. The filter is expected to reduce iron and manganese to levels well below the secondary drinking water standards of 0.3 mg/L and 50 ug/L, respectively.

Test results for samples collected from the start of filter operation through June 19.  The table shows results for unfiltered water and filtered water as it entered the distribution system.  All samples were analyzed by a certified drinking water laboratory.

Water quality issues had been a problem at Well 29 since its start-up in 2005. Elevated levels of these naturally occurring minerals led to discolored water observed at customer taps as well as stained laundry and plumbing fixtures.

Well 29 completed a 30-day commissioning period on May 15, 2009, and is now in full production. The filter is removing well over 95% of the iron and manganese from the well with finished water concentrations consistently below 0.10 ppm for iron and 10 ppb for manganese. This is well below the EPA secondary (esthetic) drinking water standards.

The contractor, Staab Construction of McFarland, finished work on the site including site cleanup and landscaping and was off site by June.

The well will be pumping year round and deliver over 1.6 million gallons per day to East Side residents.  An open house of the facility was held Saturday, August 15.
