Water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. Look it up now! One approach tested during the project was an advanced oxidation process (AOP) using ozone and hydrogen peroxide as part of a combination of independent remedial technologies for cleaning industrial wastewater at two pilot sites.
