This site provides guidance for submitting water quality data to Montana DEQ’s MT-eWQX database. MT-eWQX is DEQ’s main repository for storing water quality monitoring data, which includes physical, chemical, biological, and habitat data from a variety of projects across the state. Data submitted to MT-eWQX gets submitted to EPA’s National STORET Warehouse, which fulfills the STORET requirement of environmental monitoring projects funded by federal monies, such as 319 grants or 106 funds.

Step 2: Validate Your EDD

After Step 1 is complete, your MT-eWQX EDD is ready for data validation using the EQuIS Data Processor (EDP).
