Why illegal dumping is a public health problem

  • Decomposing garbage and other solid waste can provide food and a home for rats, other rodents, and other disease vectors. A vector is an insect or animal that has the potential to carry disease.
  • Illegal dumping can directly impact people’s health, as well as contaminate the soil and our water supply. This can create downstream health effects on people and the environment.
  • By creating eyesores on our streets, illegal dumping reduces our quality of life, property values, and a feeling of safety and well-being in our communities.
