street sweepers responded can be pinpointed to the Runoff Report of 1998. As older street sweepers were only effective in removing large particles of road debris, small particles of debris remained behind in large quantities. The remaining debris was not seen as an aesthetic issue because rain would wash them away. Today, small particles are known to carry a substantial portion of the stormwater pollutant load. Street sweeping can be an effective measure in reducing pollutants in stormwater runoff. The Environmental Protection Agency considers street sweeping a best practice in protecting water quality.
