Underground Tank Leak In Lacey
An underground tank that is used to treat wastewater for the City of Lacey has developed a crack, resulting in leakage of wastewater treatment material into soil surrounding the tank. The tank is located in the Avonlea Park area.
Lacey Public Works discovered the leak during a routine inspection of the tank, which is the size of a typical septic tank. The material is widely used to neutralize odor from wastewater, and has high nitrogen content, similar in composition to fertilizer. In certain concentrations, the product could be classified as Class D , the lowest toxicity classification that exists. The City is taking immediate steps to contain the leakage and isolate the affected soil.
The leak poses no public health threat to residents in the area or visitors to the park. Mitigation work will include the excavation of the tank and surrounding soil, which is expected to last approximately two weeks. Sewer services are not expected to be impacted.
