Information on updating GPS information and types of GPS technology acceptable for submitting data to TCEQ.

SWAP GPS Update Tools

The most accurate means for collecting spatial information is by using global positioning system (GPS) technology. The safest, most convenient way to submit this data to the TCEQ SWAP team is electronically. The SWAP team has set up a dedicated GPS e-mail account. Qualified individuals who collect and submit GPS data for either PWS or PSOC data updates may e-mail their data to the account. The e-mail administrator will determine whether the data is acceptable and either upload the data or notify the sender that the submission is unacceptable.

The following resources are designed to aid those who wish to collect and submit GPS data that pertains to PWSs or PSOCs.

What Types of GPS Technology Are Acceptable?

Our operating policy and procedure for GPS (TCEQ OPP 8.12) describes what GPS technology may be used. As a rule of thumb, only professional-grade GPS receivers with an accuracy threshold of 2–5 meters are considered acceptable. Recreational GPS receivers are not acceptable.

Are There Special Qualifications for Submitting GPS Data?

TCEQ OPP 8.12 allows only those individuals who have received training from a qualified instructor to collect and submit GPS data to TCEQ. Manufacturer-certified training is considered acceptable if it meets the criteria. We do not provide GPS training (except to our own employees), but we may issue GPS certificate numbers to professionals with appropriate training.
