Mercury Contamination

PCB Contamination

Mercury is a global pollutant. Its toxic properties are well understood. Although in this day and age, there few practical needs for mercury, it was commonly used in thermometers, switches, paints, dental fillings, and flow measurement equipment.

For many years, the oil and gas industry used large amounts of mercury in devices known as manometers. They were used almost exclusively to measure the flow of gas, until the late 1970’s, when electronic flow devices became popular.

Years of operation of mercury manometers has left many gas processing, compression and metering sites with significant mercury contamination trapped under the walls and floors of buildings and in the soil surrounding where manometers had been in operation.

Although most companies have replaced their mercury manometers, mercury may still remain in the ground onsite. Mercury is considered to be a priority pollutant and in some parts of North America and Europe, it is regulated to near background levels (e.g. 0.2ppm).
