1. A method for testing the integrity of a containment sump in contact with a matrix with a testing apparatus, the testing apparatus comprising at least one underground fixture, a test chamber, a conduit structure providing fluid communication between the underground fixture and the test chamber, and a pressure source for exerting a pressure that is communicated to the underground fixture via the conduit structure, the method comprising:
positioning the at least one underground fixture proximate to the containment sump in contact with the matrix;
releasing a test media into the testing apparatus such that the test media enters the at least one underground fixture;
generating a positive pressure within the testing apparatus for a time period, the positive pressure being communicated to the at least one underground fixture to force the test media out of the at least one underground fixture and into the matrix surrounding the containment sump; and
testing for the presence of test media within the containment sump.
