Through the analyzation of groundwater monitoring wells surrounding the plant excessive amounts of cobalt, chromium, lead, sulfate, strontium, nickel, manganese, boron, and beryllium were found with toxic levels well above the Environmental Protection Agency's regulations in 16 out of the 19 groundwater monitoring wells.

Well clusters consist of a closely spaced group of monitoring wells, each well completed to a different depth in individual boreholes. [1] Well clusters were first used in the 1950s at contaminated sites. [3] Because there is only one well screen in each borehole, there is little risk of vertical connection between zones. [3]
The following are approximate tallies of current listings by county. These counts are based on entries in the National Register Information Database as of April 24, 2008 [3] and new weekly listings posted since then on the National Register of Historic Places web site. [4]
Nested wells, also referred to as nested monitoring wells, are composed of multiple tubes or pipes, typically terminating with short screened intervals (2–3 ft), installed in single boreholes. Sand packs must be installed at the screen depths and seals in the borehole are constructed between the sand packs.
An API well number can have up to 14 digits divided by dashes as follows: Example: 42-501-20130-03-00 [7] The "42" means that this well is located in "State Code" 42 which is Texas. The "501" means that this well is located in "County Code" 501 which is Yoakum County. The "20130" is a "Unique Well Identifier" within the county.

A slug test is in contrast to standard aquifer tests, which typically involve pumping a well at a constant flowrate, and monitoring the response of the aquifer in nearby monitoring wells. Often slug tests are performed instead of a constant rate test, because: time constraints (quick results, or results for a large number of wells, are needed),
