Update : AgriLife Extension TCWP GIFT program has finished sampling more water quality samples from Exploration Green. Sampling ran from April of 2023 through February of 2024. We added new sites to the existing outfall location at Exploration Green to collect samples from Phases 1, 3 and 4 outfall locations. All sampling data and documentation should be fully compiled soon. Look out for more updates!

Comparative Data Charts
data consists of all field samples collected so far
Things to consider: Data suspected to be inaccurate was left out of the graph for both the ammonium and dissolved oxygen charts. Trendlines for phase 3 stagnated for three sampling cycles as there was no flow source to sample from at the site. A new probe for the nitrogen content of ammonium was acquired on 9/6/2023 and future sampling, especially for site 4, reflects a lower-value stable trend. Most sample data represents that from collected water rather than probing directly into the water source. Flow data and rainfall data contain flawed values from technical failure. A meter stick was used for comparison and replaced values in the field data report that was majorly inconsistent.

NA stands for Not Available meaning there was no data collected for that site on that date.
-Signify that the follow up data was collected on another date 24 hrs. after the initial rainfall event (not all samples have follow up data available)
* designate samples where the YSI pH meter was not recording correctly therefore pH is out of range and not to be used in analysis.
