Case Studies
Included in this section are case studies that illustrate various treatments and/or programs as implemented in a state or municipality.
Each case study includes a description of the problem that was addressed, relevant background information, a description of the implemented solution, and any quantitative results from evaluation studies or qualitative assessments. Also included for each study is a point of contact in the event that further information is desired. Please note that in some cases, the specific individual listed may have left the position or agency. There should still be someone at the municipal or state agency that is familiar with the project and can provide any supplemental information.
