Asbestos in water? How to address ‘non-standard’ samples of industrial and other effluents
Biohazards and other interferences complicate the employment of off-the-shelf asbestos in water methods by traditional TEM techniques. Laboratories must implement creative strategies to prepare and analyze these samples to produce meaningful analytical data. Laboratory and personnel safety have to be considered before sample handling. The interferences also greatly diminished any reasonable ...
Got deteriorating asbestos cement water mains?
Asbestos has come to be one of the most feared words and materials in the world. Yet, in the 1940s, 1950s and 1960s, more than 600,000 miles of asbestos cement– also called transite – used for its light weight, corrosion resistance, rigidity, ease of handling and installation was installed to handle water throughout the United States. Applications included potable water mains, storm ...
Water aggressiveness and hydrodynamic effects on the fibres release in asbestos-cement pipes for public water supply
SEM and TEM analyses of drinking water samples, collected during three years (1988, 1989 and 1990) from some Asbestos-Cement (A/C) distribution systems in Veneto Region (Italy), have shown that the release of fibres, with length greater than 10 μm, is, on average, quite low. Moreover, the asbestos concentration is not strictly dependent on Aggressiveness Index (A.I.) in the range ...
The Asbestos Debacle
Society and industry are diligently working to find better solutions through waste reduction, recycling and reuse, but what is the plan for hazardous materials, such as asbestos, in buildings and property? Known as the miracle mineral, asbestos was used for its resiliency against chemical attack and its excellent tensile strength and superior fire-proofing characteristics. The material was used ...
Environmental impact of cured-in-place pipe renewal on an asbestos cement water main
According to the US Environmental Protection Agency's (USEPA) estimation, asbestos cement (AC) pipe accounts for approximately 15% of the total length of pipe networks for water distribution systems in North America; and just as other pipe materials, the AC mains are deteriorating and are in need of attention/renewal. However, there are concerns surrounding the environmental impact of AC pipe ...
Prevent indoor air quality (IAQ) problems through regular testing programs
Indoor Air Quality (IAQ) Testing Programs We now offer a program designed to prevent Indoor Air Quality complaints and maintain good IAQ in commercial buildings. This program would include quarterly or semi-annual routine inspection of a commercial building (office, public service, retail, or entertainment). The testing programs would include an initial inspection focused on general indoor air ...
The Phase 1 Environmental Assessment
In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property. Lenders ...
Fire and Smoke residual air contaminants testing
Only recently has the ability to accurately test for the residuals of fires become possible. There have long been concerns for the health of firefighters from fire emissions. Also, occupants of buildings and even neighborhoods affected by fire and the residuals of those fires are often greatly concerned about contaminants that exist for days, weeks, months, after the fire has been extinguished. ...
