2017 was a great year for the WaterOperator.org newsletter team. We not only reached our 200th edition milestone this past fall, but we also were successful in connecting a significant number of water professionals with useful and relevant resources, resources that could be used on-the-spot to solve pressing issues, or help guide utility best practices, or help water decision-makers plan ahead for their communities. While many of the events, articles and resources featured in our newsletters garnered interest, here is a list of our most clicked-on resources of 2017 . A Water Security Handbook: Planning for and Responding to Drinking Water Contamination Threats and Incidents , US EPA This document provides guidelines for utilities to plan for possible contamination incidents, including sampling, public health procedures, and recovery. At the Confluence of Nutrients, Pharmaceuticals and Sustainability: Emerging Issues in Wastewater Management , University of Michigan/ Central States Water Environment Association This presentation discusses the effects of emerging contaminants on wastewater treatment and possible solutions. Sampling Guidance for Unknown Contaminants in Drinking Water , US EPA This document provides new guidance to first responders and drinking water utility operators on the collection, storage, and testing of potentially contaminated drinking water when the contaminant is unknown. Water Conservation Techniques For Small and Medium Water Systems , Florida Rural Water Association This paper provides thorough descriptions of water conservation measures that have been demonstrated to be effective for small water systems. The State of Public Water in the United States , Food & Water Watch A compilation of water rates of the 500 largest community water systems in the country (the largest water rate survey of its kind in the country).
