Aquifer/Well Field Investigation

By deriving data from a series of test wells and observation wells, we can accurately predict the amount of water available for withdrawal without harming the future sustainability of the aquifer. This data can also provide other valuable information such as proper well spacing, radius of influence, and aquifer storage coefficients.

Epoxy Coating


No part of a facility escapes punishment: every tank, pipe, pump, valve - in fact, virtually every piece of process pumping equipment - needs long-term protection. Our coating process utilizes the latest technology to apply a Tnemic coating system tailored to your specific application to increase the lifespan of your equipment.
