This document discusses illegal dumps in urban and rural areas of Puerto Rico. Illegal dumps are unregulated landfills that pollute the environment and can spread diseases. They proliferate due to Puerto Rico's large amount of waste generation and population density. The author proposes to survey and map illegal dumps in 21 neighborhoods of Cayey, Puerto Rico to analyze differences between urban and rural areas. The goal is to collect data on dump locations, waste composition, and population density to inform future environmental studies and prevention initiatives.
