Tech Brief: Basic Water and Wastewater Formulas - Operators obtaining or maintaining their certification must be able to calculate complex formulasand conversion factors. This Tech Brief provides basic examples of these formulas and conversion factors.
Tech Brief: Sanitary Surveys - A sanitary survey is an inspection of the entire water system, including the water source, facilities, equipment, operation, and maintenance. Usually conducted by a member of the state primacy agency, the purpose of these mandatory surveys is to help prevent and correct water system deficiencies.
Tech Brief: Simultaneous Compliance with Drinking Water Regulations - Certain U.S. drinking water regulations—in particular the Stage 1 and 2 Disinfectants/Disinfection By-Products Rules and the Long-Term 1 and 2 Enhanced Surface Water Treatment Rules—have the potential to conflict with each other, as well as with other regulations such as the Lead and Copper Rule and the Total Coliform Rule. This means that small system operators cannot simply comply with these mandates individually, but must consider how changing their treatment process to meet one rule might affect compliance with other rules. This Tech Brief provides information and strategies to effectively comply with those regulations that are most likely to conflict with one another.
Fact Sheet: Water Conservation Measures - This fact sheet considers the role of water conservation as an integral part of long-term resource planning.
Tech Brief: Source Water Protection - Because source water protection means cleaner water that needs less treatment, drinking water systems should put source water protection at the top of their “to do” lists. Whether your source water is surface or groundwater, all drinking water sources are vulnerable to a variety of contaminants from a variety of activities. This Tech Brief discusses some possible contamination sources and feasible ways to address them.
