California Laboratory Intake Portal (CLIP)


The State Water Resources Control Board Division of Drinking Water (DDW) is excited to announce the development of a new drinking water quality data intake portal. This portal, known as the California Laboratory Intake Portal, or CLIP, will replace the current intake portals known as WQM (Water Quality Management) and LTS (Lab-To-State). CLIP will be implemented in phases, beginning with chemical and radiological analyses; with the goal of ultimately being the intake portal for all drinking water quality data (microbial analyses will not be included in the first phase of CLIP). This effort will result in a single point of access for laboratories for drinking water quality data reporting requirements, which should help facilitate reporting. Additionally, CLIP will include a data validation while ensuring quality control elements. This will allow laboratories to demonstrate submission of data with known and documented quality. The use of CLIP should result in streamlined access, improved electronic data reporting, and the ability to document the submission of reliable and defensible data.

Development of CLIP is being performed by DDW with a vendor, EarthSoft. As part of this effort, a new reporting format known as “CA_SDWIS_Lab_Analytical_Data” is being developed that will replace the current electronic reporting data format specified in regulations. Regulation revisions are pending, which should incorporate the new reporting format. The new reporting format should facilitate the submission of water quality data analyses while collecting appropriate quality control elements. Information regarding future regulation changes will be made available as they are developed.

CLIP Pilot Testing

DDW’s Data Management Unit solicited for volunteers to test CLIP prior to implementation. Volunteers were selected and testing completed February 2021.

CLIP Registration

In 2021, all laboratories and their data submitters will be notified of the need to register, establish their identity, and obtain authorization to sign a submission electronically prior to using CLIP.

Electronic Subscriber Agreement Form
Form to print, sign, and mail to DDW. The form is an agreement for data submitters and legally responsible officials of electronic submittal requirements and responsibilities. The form is required to activate user accounts for data submittals. DDW will activate your CLIP account when the form is physically received and verified.

  1. Submit a filled-out electronic version as-is to DDW by clicking the Submit button in the Form (signature not required, do not scan PDF). This unsigned electronic version is to make the CLIP Team aware that your signed form is in the mail and should be received in our office soon.
  2. Mail a completed signed form to DDW (mailing address is provided on the form).
You can download the form at the CLIP Resource Page.

CLIP Training

TBA – EarthSoft will provide laboratory training prior to implementation to ensure familiarity with CLIP. Trainings will be recorded for future reference.

CLIP Launch

TBA – CLIP is anticipated to launch in 2021.
CLIP will replace the WQM and LTS portals.
WQM and LTS will be offline after CLIP launch.
