Nationally publicized lead exposure events, including exceedances in Washington, D.C, and the more recent tragedy in Flint, Michigan, have turned attention toward the issue of corrosion. As such, the United States Environmental Protection Agency (US EPA) is expected to issue revisions to the 1991 Lead and Copper Rule (LCR) in 2017. The National Drinking Water Advisory Council has provided the US EPA with several recommendations for these revisions, ranging from new sampling techniques to greater attention on the impacts from premise plumbing. Due to this increased attention, the State of Colorado has recently re-assessed the way they interpret the LCR, which previously focused on lead action level exceedances only. This paper will focus on a recent (March 2017 to August 2017) corrosion control study implemented at the South Adams County Water and Sanitation District.
In 2010, the South Adams County Water and Sanitation District (District) surpassed the 50,000 population to transition from a medium system to a large system classification based on the Colorado Primary Drinking Water Regulations (CPDWR). Although the District does not have any lead service lines or history of lead or copper exceedances, transitioning to being considered a large water system dictates that the District complete an LCR corrosion control study.
The District is currently conducting a six (6) month bench-top corrosion control coupon study evaluating their primary sources of water and candidate corrosion control technique strategies for distribution and premise plumbing. The District utilizes shallow water, deep water and surface water as their primary drinking water sources. As such, the variability in source water quality plays an important role in evaluating different corrosion control techniques. The overarching goal of the corrosion control study is to select a recommended corrosion control technique.
This paper will review the process for preparing and conducting a corrosion control study, as well as review the testing results, unintended consequences evaluation and recommended corrosion control technique.
Meet at Registration Desk to travel to Historic Downtown Hailey.
Tour Blaine County Historical Museum - visitors can explore the Wood River Valley’s pioneer past, research family histories, and view vignettes of mines, schools, ranches, famous literary personalities, period fashions, and political memorabilia.

Energy efficiency means capital projects, right? New pumps and VFDs, control system and instrumentation, LED retrofits and HVAC upgrades, and more? It certainly can mean that, but it doesn’t have to! Come learn how facilities in Utah are reducing costs while maintaining and even improving water quality without capital projects. Working individually and with peer groups, water professionals have reduced their annual energy consumption from 5%–15% through a focused, facilitated review and optimization of their operations. Strategic energy management best practices and tools create energy awareness and action within the O&M crew, while energy models and metering allow results to be quantified and shared. The results are impressive, the costs are low, and the opportunities are everywhere.
