Health officials in Mesa County, Colorado, were recently alerted to two local measles cases, which were particularly concerning because both patients contracted the virus from an unknown source. However, local leaders were able to quickly prevent a major outbreak, thanks to an early warning signal from the sewer system. Days before the first human case was identified, the Colorado Department of Public Health and Environment detected the measles virus through wastewater testing and immediately notified the county to prepare.
This successful containment is an example of the evolving role of wastewater surveillance in public health. The technology, which was initially used during the COVID pandemic to track the overall flow of the virus, is now being adapted in Colorado to act as an early detection system for emerging diseases, such as measles, even when only one or two people are infected.
Thames Water Removes 100-Ton Fatberg
Thames Water in England recently completed the removal of a massive 100-ton fatberg from a west London sewer. The solid blockage was located more than 32 feet below street level and was composed primarily of wet wipes, held together by solidified fat, oil and grease.
A specialist team spent over a month accessing the sewer through a manhole, using chiseling and sucking equipment to clear the 410 feet of pipes before craning the waste into skips for landfill disposal.
