Abstract
An understanding of pollutant characteristics on impervious surfaces is essential to estimate pollutant wash off characteristics and to design methods to minimize the impacts of pollutants on the environment The data also show that street sweeping may have an adverse impact on pollutant wash off because the street sweeper releases the finer material but only removes some of them, making the fine sediment available for wash off by the next storm. The data also show that most of the nutrients are attached to the finer sediments, and to effectively reduce nutrient loads in particulates, treatment facilities must be able to remove the finer particles. Street cleansing is a common (and expensive) practice undertaken by most urban municipalities with annual expenditure by a municipality often exceeding one million dollars. Street sweeping, essentially the operation of large trucks for cleaning street surfaces, is primarily performed for aesthetic purposes. It is, often perceived to lead to improvements in the environmental conditions. The study concludes that the performance of street sweeping for storm water pollutant control is limited and must be accompanied by structural pollutant treatment measures to effectively reduce the discharge of gross and sediment associated pollutants in storm water. The incremental benefits in increasing the frequency of street sweeping beyond what is required to meet street aesthetic criterion is expected to be small in relation to water quality improvements. As a result, there seems little benefit in conducting an in-depth field-based study into the effectiveness of street sweeping for storm water pollution control.
