ig Inadvertent Liquid Releases Dresden In August of 2004, the licensee Identified an underground leak of Its condensate storage tank (CST) piping. The licensee detected levels of tritium In onsite groundwater monitoring wells as high as 1,700,000 picoCuries per liter. The licensee Isolated the leakage and replaced the faulty section of piping (November 2004). Onslte monitoring well data confirm that the flow of groundwater Is generally away from any residential areas and towards the River.'

In 2004 and 2005,.the licensee sampled the private wells of nearby residents. One of the residents' wells had measurable levels of tritium above background (approximately 900 - 950 picoCuries per liter) and has shown posltive.results for tritium for a number of years. However, the'licensee's other monitoring results and an Independent hydrology study do not appear to support that the elevated levels of tritium-In that well were from. the'2004 CST pipe leakage.

The licensee continues to evaluate the tritium In that well, which Is a normal sample point for its radiological environmental monitoring program.

In 1993 or 1994, the licensee Identified that the Unit 1 Service Water line had frozen. As a result, contaminated liquid may have been released to the environment.
