The Kenedy County Groundwater Conservation District manages groundwater resources across multiple counties in southern Texas. It was created in 2003 and confirmed by voters in 2004. The district monitors water wells and sets production limits to ensure equitable distribution of groundwater amongst users. Key economic activities in the region include oil and gas production, agriculture, and uranium exploration. The district works to protect groundwater quality by collecting baseline water data and engaging in rulemaking around mining activities.

9. RULES
RULE 5: REPORTING AND
RECORDKEEPING
5.1 Well Drilling, Completion, and Water Data
Reporting
5.2 Annual Water Production Report for Non-Exempt
Wells
5.3 Plugging Report
5.4 Annual Water Production Report for Exempt Oil
and Gas Water Wells
5.5 Water Wells Associated with Uranium Exploration
and Mining
5.6 Texas Surface Coal Mining and Restoration Act
and Water Wells
5.7 Water Pollution Event Reporting
10. RULE 9: WATER WELLS ASSOCIATED WITH
URANIUM EXPLORATION AND MINING
9.1 Uranium Exploration Activities
9.2 Development of an Area Permit
Application
9.3 Activities Affecting Groundwater
Allocation
11. RULE 10.4: SPACING FROM
PROPERTY LINES
Wells –
Pumping Capacity
(gallons per minute)
Distance of New Water
Well from Property Lines
(in feet)
Less than or equal to 20 gpm 100
20 to 250 gpm
5 feet per every gallon
per minute
Greater than 250 gpm
10 feet per every gallon
per minute
13. PRODUCTION LIMITS
True correlative rights
Prior to first MAG –
Existing wells = highest annual production
preceding 5 years plus 25% or beneficial use
without waste plus 25% - this becomes the
“set aside” in the formula
New wells = 0.75 acre-inches per acre per
year
When MAG issued, MAG changes, or territory
is added, production limits change except for
“set aside” wells
14. PRODUCTION LIMITS
Formula = MAG divided by
number of surface acres in
district minus set aside for
exempt wells and minus set aside
for “existing” permitted wells
Current production limit = 0.6
acre-inches per acre per year
15. RULE 13: WATER WELLS ASSOCIATED WITH OIL, GAS,
AND MINING ACTIVITIES OTHER THAN IN SITU URANIUM
MINING
13.1 District Jurisdiction over Water Wells
Associated with Oil, Gas, and Mining Activities
13.2 Water Wells Associated with Mining
Activities Authorized Under Texas Natural
Resources Code, Chapter 134
13.3 Water Wells Associated With Oil and Gas
Activities

18. The primary economic
activities within the District are
oil and gas production and
agriculture (primarily livestock).
Windfarming; uranium
exploration
26. WATER WELL MONITORING
The District has been very involved in rulemaking at
the TCEQ and RRC regarding uranium exploration
and mining.
At the time, there were controversies in near-by
counties about whether water well contamination
had been caused by uranium exploration
In order to establish background water quality, the
District took pre-exploration water samples from
wells within and surrounding the first (and until now
– only) uranium exploration permitted area in the
District

The numbered wells are the ones that were sampled by the District. Yellow line delineates the boundary of the exploration area.Samples were analyzed for arsenic, calcium, magnesium, manganese, molybdenum, selenium, anions, alkalinity, ammonia as nitrogen. Gross alpha/beta analysis, isotopic uranium by alpha spectroscopy, and RA-226 by Radon Emanation were also performed on the water samples.
