Drinking Water Electronic Lab Reporting SystemS
DWELR & WebOAS Registration Form and General Information
DWELR & WebOAS Registration Form (3800-FM-BSDW0021 Rev 5/2012)
The Drinking Water Electronic Lab Reporting (DWELR) web application
DWELR enables the secure submittal of drinking water sample data over the Internet. The data can be submitted via uploading formatted files or entered using screen entry forms. The submitted data is checked and DWELR returns an error report that can be corrected immediately or recalled later for correction (prior to midnight on the 10th of the month). A submitting entity is allowed to edit and view only the data that it submitted. Water systems can register for access to view data submitted for their system by submitting entities. On the 10th of each month as required by Chapter 109 of Title 25 of the Pennsylvania Code, all data is cleared from DWELR and passed to the Pennsylvania Drinking Water Information System (PADWIS) for monthly compliance processing. Detailed instructions are contained in the DWELR web application including the data formats required for upload.
The Web Optimization Assessment Software (WebOAS) application
WebOAS allows the Department of Environmental Protection (DEP) to receive monthly turbidity data from raw water, sedimentation basin effluent, and combined filter effluent samples taken at surface water treatment plants. DEP can use this data to prioritize state assistance efforts. WebOAS is not a substitute for submitting compliance monitoring data as required by Safe Drinking Water Regulations. Compliance monitoring data must be submitted using DWELR.
Accessing DWELR and WebOAS
Potential users must establish a DEPGreenPort user profile in order to access DWELR or WebOAS. You may already be using DEPGreenPort if, for example, you use the Internet to submit information under Act 220 or another DEP Program. If so, you may continue to use the same username and password to access DWELR and WebOAS.
If you do not have a DEPGreenPort user profile, please go to the GreenPort webpage. On this page there is a button, "Click here to self-register", which allows you to create your DEPGreenPort user profile. After you have created your user profile, you may submit a DWELR & WebOAS Registration Form to DEP. This form requires you to identify your DEPGreenPort username. Note that individuals are not permitted to submit information via DWELR using a DEPGreenPort account created for another person.
Important: Any facility performing testing or analysis in order to comply with a permit or regulation administered by PA DEP is required to register with DEP's Bureau DEP's Bureau of Laboratories (BOL)This includes testing for residual disinfectant concentration and pH in drinking water. A DEP laboratory identification number (Lab ID) is required to submit sample results using DWELR. To register with BOL, submit a completed Environmental Laboratory Registration Application per the instructions included with the registration application.
