EPA has published A Primer on Using Biological Assessment to Support Water Quality Management.  This technical document serves as a primer on the role of biological assessments in a variety of water quality-management program applications, including reporting on the condition of aquatic biota, developing biological criteria, and assessing environmental results of management actions.  The primer provides information on new technical tools and approaches for developing strong biological-assessment programs and examples of application of biological-assessment information

EPA is releasing the Control and Mitigation of Drinking Water Losses in Distribution Systems guidance document. This guidance provides information on flexible tools and techniques that may help a public water system (PWS) tailor a program to meet its water-loss prevention needs and maintain its infrastructure to deliver clean, safe drinking water to customers – often a significant challenge for the operator of PWSs and particularly for small water systems.
