Historically, corrosion control in the United States for Lead and Copper Rule compliance has focused on treatment to reduce the distributed water's plumbosolvency. Corrosion control treatment (CCT) typically focuses on either control of pH and alkalinity, development and maintenance of Pb(IV) scale under oxidized conditions, or use of orthophosphate‐based corrosion inhibitors. These CCT methods are influenced by source water quality parameters such as pH and dissolved inorganic carbon; thus, CCT can potentially be affected when source waters with different water qualities blend in the distribution system. If portions of the distribution system are exposed to blends of source waters with disparate water qualities, testing may be warranted to determine whether optimal CCT is being maintained where and when blending occurs, especially in transitional periods. This article discusses the theoretical impacts of blending source waters with different water qualities and presents research that was conducted on waters from two utilities to illustrate the potential impacts that source water changes can have on CCT.

Clean water is vital to sustaining our natural environment, human health, and our economy. As infrastructure continues to deteriorate and water resources become increasingly threatened, new technologies will be needed to ensure safe and sustainable water in the future. Though the US water industry accounts for approximately 1% gross domestic product and regional "clusters" for water technology exist throughout the country, this emerging industry has not been captured by recent studies. As use of the term "cluster" becomes more prevalent, regional mapping efforts have revealed international differences in definition yet showcase this industry's economic impact. In reality, institutional processes may inhibit altering industry coding to better describe water technology. Forgoing the benefits of national economic tracking, alternative data sets are available, which may support new ways of identifying these clusters. This work provides cluster definitions; summarizes current approaches to identifying industry activity using data, interviews, and literature; and sets a foundation for future research.

Our knowledge of drinking water and health has increased by leaps and bounds since the 1800s. But where is that knowledge coming from? Is it derived from research‐based inquires, or the practical implementation of water treatment facilities where we learn from experience? In the fields of education and health care, there is a recognized research‐to‐practice gap, in which there is a lack of knowledge transfer from researchers to practitioners.

A 10‐month pilot test of advanced oxidation processes helped find the most efficient reuse solution for the city of hollywood to address new florida statutes.

Natural organic matter (NOM) was collected, concentrated, and lyophilized on a monthly basis for 15 months to create a temporal NOM library and assess seasonal variability of untreated Ohio River water. Using fluorescence spectroscopy with parallel factor analysis, similar spectral components for both the ultrafiltered source water (UF1X) and reconstituted lyophilized NOM were observed in a two-component model throughout the study, with overall average emission and excitation wavelengths of 418 nm and 270 nm, respectively, for component 1 and 482 nm and 370 nm, respectively, for component 2. Fluorescence spectroscopy, high-pressure liquid chromatography-size exclusion chromatography, and elemental analysis indicated that the NOM was humic-like during the study with only small seasonal changes. Data from these analyses also demonstrated similarity between results for UF1X, reverse osmosis-concentrated NOM, and reconstituted- lyophilized NOM, validating the use of the reconstituted- lyophilized NOM as a surrogate for its source.

Engineers and utility managers have always thought about capital projects in terms of economic viability. Does it make economic sense to build that pipeline or replace that treatment plant? As a result of societal and environmental realities, we must now pay attention to how sustainable a new project might be. What are the environmental impacts in the supply chain? Is that new building having the least impact on water resources, heating requirements, and electrical energy demands? Are the materials used the best from a sustainable point of view? What are the energy requirements, and can they be met using renewable energy supplies? With the predicted impacts from climate change, sustainability has become a more urgent requirement for water projects.
