Heating oil tanks—especially older or underground ones—can create serious risks when they begin to fail. Pressure issues during oil deliveries, aging metal, and poor venting can all lead to leaks that remain hidden until significant damage has already occurred.

For decades, underground steel heating oil tanks (USTs) were installed throughout the Hudson Valley, including the Town of Carmel, Putnam Valley, and Scarsdale. Many of these tanks are now 25+ years old—well past their lifespan—and prone to corrosion and leaks. A leaking tank can contaminate soil and groundwater, leading to costly environmental cleanup that may not be covered by insurance if your policy includes a “pollution exclusion.” 

Based in Hawthorne, New York, Tri State Environmental Services is a top-rated provider for preventing, managing, and cleaning up petroleum spills across the Hudson Valley.

For decades, steel underground storage tanks (USTs) were the standard for heating oil and fuel. But steel doesn’t last forever. Over time, rust eats away at the shell and seams, creating holes that allow petroleum to leak into the soil and groundwater.
