According to Chadwick's report in 1842, which city had unsanitary conditions from burials?

Chadwick's report, published in 1842, highlighted significant public health issues related to unsanitary conditions in urban areas, particularly concerning the impact of burial practices on the environment and public health. The report primarily focused on London, where the overcrowded and unsanitary burial practices led to concerns about water contamination and disease spread.

Chadwick pointed out that many urban cemeteries were placed too close to drinking water supplies, leading to the contamination of water sources with pathogens from decomposing bodies. This situation was critical in London, prompting public health reforms and changes in burial practices at the time. Thus, the identification of London as the city with these grave unsanitary conditions aligns directly with the findings of Chadwick's report and his advocacy for better public health policies.
