eWell consists of two components: an iPhone application for recording and submitting data to the eWell database, and the eWell database (part of Locus' EIM system) for creating sampling routes and reviewing the collected data sent to the database.

Using EIM, eWell users can create "sampling routes": a list of wells or locations that require measurement of water level and other field parameter data. Users can download these routes to the iPhone, along with selected historical environmental data on their wells, for use in the field for real-time validation and QA/QC of collected data. Once downloaded to eWell, the well locations can be seen and accessed directly from the iPhone's Google Maps interface.

Once in the field, customers can use their iPhones, iPod Touches, or iPads to record water levels, pH, turbidity, and other environmental readings, as well as to compare current and past readings. Where Wi-Fi or 3G coverage is available, data collected in the field uploads instantly to EIM. Where access is unavailable, data is saved automatically, and can then be uploaded when coverage becomes available. eWell for the iPhone completely streamlines the data upload and download processes, eliminating any steps that require equipment synchronization.

Once in EIM's data review tables, users can review uploaded data for accuracy and completeness. After completing all data validation checks, field readings are moved to live EIM for reporting and other project uses. EIM is part of Locus' ePortal SaaS platform. As is the case for all other applications that Locus has pioneered over the last decade, eWell is designed to lower a company's environmental expenditures while improving data quality.

For information that cannot be collected through interfaces to other applications, such as from analytical laboratories LIMS systems, data historians or wireless sensors, eWell offers a powerful alternative that eliminates duplicate input, reduces transcription time, performs data checks and validation at point of collection, and maintains a complete audit trail, including the georeference on who did what, when, and where.
