Well Owner Resources

Arm yourself with information!  There has been a lot of interest from well owners looking for guidance on a number of different topics.  Here’s a compilation of the top links, resources, and recommendations from those in the know!

Water Well Sampling Options, Guidance and Recommendations

The US EPA testing guidance for private well owners includes both annual testing and additional testing if well owners notice a change in taste, odor or appearance.

Notify your Groundwater Conservation District if you notice a construction-related impact.

In regards to recent construction activity, the LCRA lab has processed samples for Total Suspended Solids and total trace metals (method code 200.8).

Understanding Water Sample Results

Sediment Impact on Wells Updates:

The Texas Well Owner Network (TWON) has a large number of Well Owner Publications and Factsheets to reference.  Here are our top picks:

Searching for a well record

Each time a driller installs a well, they submit a well report that documents how deep the well is, date drilled, and the well construction.  Many well owners have a copy of the original well record, but here is some guidance to help find it if you don’t.  There are two online resources available, depending on the date your well was drilled.

Wells drilled from 2003 – present:
Search the TWDB Water Data Interactive map viewer. 

TWDB Water Data Interactive

Here are some helpful tips to streamline your search.  Read through these steps as you search:

    1. Address search:  use the search bar in the upper left corner to zoom to your address.
    2. Turn on Submitted Drillers Reports wells (orange dots):  Click the Groundwater tab, click the check box to turn on the Well Reports.  Note:  Purple dots are part of the Groundwater database and contain links to useful water level and water quality data.
    3. Click on dots and use the hyperlink within the pop-up window to view the well report.  Note: Accuracy of location can vary, so click on dots within your search area.  Oftentimes the original well owner name is a key field to help find the record.

Wells drilled before 2003:
Search the TCEQ  Historic Well Log Viewer

If your well was drilled prior to 2003, it is oftentimes more challenging to find the original well record.  If you know the original driller, many times the driller has kept a record of the well log.  It’s worth a call to them to find out.  If not, sometimes the TCEQ Historic Well Log Viewer can yield a treasure!  Here are some tips to help with that process:

TCEQ Historic Well Log Viewer
    1. Find the original owner’s name & Section/lot number (this will be helpful because some scanned documents do not reference a street number)
    2. Open TCEQ’s Historic Well Log Viewer and scroll in to the area of interest.
    3. Identify the grid number that corresponds to your location of interest. Note: before GPS was widely available, drillers used a statewide grid system to approximate locations for wells.
    4. Select Plotted Water Well Reports & fill in Grid Number and County (Ex.: 68-08-5, Hays).  Open first pdf and scroll through visually searching for Owner, Address or Section/Lot of interest.  Print and save the 1-2 pages of your well record if you find it!
