Pompeii's public baths, a window into ancient Roman hygiene and water management, have shed new light on the city's water supply. Scientists analyzed calcium carbonate deposits from the baths, aqueduct, and surrounding structures to reconstruct the history of Pompeii's drinking water system.
The study focused on four distinct time periods: before 80 BCE, when rainwater stored in cisterns was used; after 80 BCE, when Pompeii became a Roman colony; during Emperor Augustus' reign (31 BCE - 14 CE); and after a devastating earthquake in 62 CE. Researchers collected calcium carbonate samples from these sites to better understand the city's water supply.
The findings indicate that Pompeii's water supply evolved over time, shifting from wells and cisterns to an aqueduct-based system. The ancient Romans built sophisticated plumbing systems, including weight-lifting machinery that lifted water up well shafts as deep as 40 meters. However, the water was not changed regularly, leading to contamination.
The study reveals improvements in technology and hygiene during different periods. For instance, after the enlargement of a well shaft, carbonate deposits became thinner, suggesting technological advancements reduced sloshing as water was raised. The aqueduct's construction led to expanded bathing facilities, likely resulting in better hygiene.
Notably, the researchers found evidence of lead contamination in the water supplied by the aqueduct, but discovered that carbonate deposits in lead pipes had reduced those levels over time. The findings also shed light on a scientific debate about the origins of the aqueduct water, supporting the hypothesis that it came from the town of Avella.
The study's results provide valuable insights into Pompeii's ancient water management system and its impact on hygiene and public health. As cities worldwide continue to grapple with aging infrastructure and water quality concerns, understanding Rome's ancient solutions can offer practical lessons for modern-day improvements.
