Pipe and Asbestos exposure

Summary

American infrastructure contains pipelines. Millions of pipes operate underground and overhead in residential homes, commercial buildings and civil buildings. Pipes weave across ships and land works. They send everything from drinking water to raw wastewater and from pressurized gas to the sewer of gravity storm. There are millions of miles of pipe snaking across the country, and many of these pipes contain deadly asbestos.

Asbestos is a major component in plumbing work beginning in the late 1800s. The government banned it in the late 1980s. Over the years, there have been warnings about health risks for people exposed to airborne asbestos fibers emitted from pipes and other asbestos-containing materials (ACM). However, asbestos is very valuable in making pipes. Finally it takes pressure from government regulators such as the Environmental Protection Agency (EPA) and the Safety & Health Administration (OSHA) to remove asbestos materials in residential, commercial and industrial pipes.

Asbestos in Pipe

Pipe making and pipe installation using materials containing asbestos in two ways. One of them is in a pipe material where ACM is building a pipe wall. The second is a pipe wrap that isolates the open pipe and adds fire resistance. Asbestos seems to be the ideal material for making pipes and pipe wrapping. Light asbestos fibers and add tensile strength to all pipe sizes. Asbestos fibers are also very smooth. These characteristics give the inner wall of the pipe a slippery surface, reduce friction and reduce pumping efforts.

Asbestos is not flammable, making it the ideal material for refractory fuel lines on ships and factories. ACM is not corrosive. This characteristic allows asbestos pipes to survive from direct burial and contact with native rust-causing minerals on the ground. Asbestos additives reduce the electrical conductivity in steel pipes making it safer around direct current and static charge. Furthermore, asbestos is chemically inert and easily mixed with other pipe-making materials. In addition, asbestos is widely available and inexpensive to buy.

Two Types of Pipes Containing Asbestos

Two types of pipes mainly contain asbestos material. The first is a steel pipe in a high pressure situation. The composition of steel usually has 10 to 15 percent asbestos on the pipe wall. However, the isolation of air cells containing 100 percent asbestos paper and fiber encapsulates many steel pipes.

The other main ACM pipe type is concrete construction.

Asbestos-Cement products (A-C) are designated, these pipes are generally given the brand "Transite."

Most A-C pipes are installed in passive underground applications for storm drains and sewers, but Transit piping is also often used for pressurized drinking water systems.

From the early 1900s to the 1980s, workers cut, installed, and buried countless Transite pipes throughout America. The A-C pipe is estimated to have a lifetime of 50 to 70 years. Many Transite pipes now fail and need to be replaced. This is the same situation with ACM steel pipes and fragile bandages.

ACM Pipes and Asbestos Exposure

MJN Brief

Asbestos materials are quite safe and stable after being installed and left alone. The danger of asbestos exposure comes from working with raw asbestos materials when making ACM pipes or disturbing fibers during installation or removal. Old and open ACM pipes are also very dangerous to emit air asbestos fibers. Dry asbestos becomes brittle and easily breaks into fine dust particles. This condition is called fragile and presents the highest risk for air asbestos exposure.

Asbestos in the Old Pipe Towards Water

The problem of old pipes in state infrastructure is not new. In its heyday, asbestos was widely used in cement pipes to create products that were stronger and longer lasting. This asbestos pipe was first laid out in the early 1930s and is believed to be more durable and resistant to corrosion. They are said to have around 70 years old.

However, in the 1950s, there were regulations for the use of asbestos pipes for municipal water. But this new standard does not mean the old pipes are removed or updated. As such, many of these old pipes are still present on the ground now and have reached or are reaching the end of their life cycle, which causes more problems for the population. Even since the 1980s, some residents have seen the dangerous risks of asbestos in their water supply.

In 1985, Woodstock City, New York experienced a disruption in their water services. Although city asbestos pipes were installed in the 1950s, local water corrosiveness helped destroy pipes that were supposed to be durable and durable for only a few decades. The contamination is so bad that the shower and faucet are clogged with asbestos fibers. Their water supply tests even showed that asbestos began to enter water around 1976. Residents were warned to stop using water, and new pipes were installed the following year.

Residents in two Texas cities began facing similar problems earlier this year and late last year. Devine, Texas, residents received a warning letter in November 2016 after the city saw levels of asbestos that were higher than those permitted in their water for a year. Tests conducted periodically from January to July show fluctuating levels of 14, 17 and 18 MFL asbestos, more than double the limit set by the EPA. Mayor Devine said city officials did not believe it was a serious danger, because they were not told to cut water supplies as in other cases, and hoped it was only a matter of testing. Although the city argued that water was still safe to drink, many residents were really worried and started buying bottled water while the city worked to get a grant to replace the pipe.

Schools in Arp, Texas, faced a similar problem with the city's old asbestos pipe in August. The mayor and city overseer for the district said the water appeared to change color and was clearly contaminated. After testing revealed asbestos at levels 10, 12 and 13 MFL in various regions, the city quickly took action. Schools were given water coolers and bottled water for cooking and drinking, and construction took place in October to replace asbestos pipes.

Natural Disasters Can Cause Contaminated Water

The nation's old infrastructure made with poisons such as lead and asbestos is not the only problem with contaminated drinking water. Sonoma and Marin districts in California are also faced with the possibility of asbestos and poisons entering their water supply after devastating forest fires in October revealed these pollutants in the burning zone. When rain is expected in estimates, officials fear that poisons will be swept into rivers and local streams - and ultimately public water supplies.

They say Sonoma itself has 617 streams that meandered through the burning zone, which feeds into the main drinking water source, the Russian River. In the latest report, the district said that the water supply remained safe for several hundred thousand people who depend on it, but would be monitored for all these poisons throughout the season. Meanwhile, EPA has a team in the field that helps clean and analyze each burning area carefully for pollutants. The regency has also issued sandbags to help catch rainwater runoff before entering water sources and potentially cause contamination.
