The Microsoft Access database can be used to record and manage ORI data.Chemical Mass Balance Model (CMBM) From the Illicit Discharge Detection and Elimination Guidance Manual Appendix I, the Chemical Mass Balance Model (CMBM).

Included here for download are the executable file and a sample input file for the CMBM. The Influence of Septic Systems at the Watershed Level From Urban Lake Management, Watershed Protection Techniques 3(4), this article is part of an issue devoted to exploring how development impacts lakes and reservoirs, and examining ways to reduce these impacts with watershed management practices.
