A significant cleanup of the pollution from the old factory was carried out by the Lazy River Environmental Group in 2010 as a result of a subsequent one-third decrease in pollutant levels and a modest increase in succeeding years. Option (1) is correct.
Three primary human activities are associated with pollution: the burning of fossil fuels, particularly by industry and transportation; the use of artificial fertilizers and pesticides in agriculture; and the expanding use and complexity of chemicals. To evaluate the efficacy of the cleanup, measurements of contamination in river sediments taken before and after the cleanup were compared.
Researchers at Carnegie Mellon University discovered that fine particulate pollution increased 5.5 percent nationwide between 2016 and 2018, after dropping roughly 25 percent over the previous seven years, according to an examination of Environmental Protection Agency data that was released this week. Between 2008 and 2009, the drop for a number of pollutants was especially rapid.

Correct Question:
The Lazy River Environmental Group organized a major cleanup of the pollution from the old factory in Inte 2010. Measurements of pollution in river sediments before and after the cleanup were analyzed to determine the effectiveness of the cleanup. Select the Sediment Pollutant Over Time dataset and follow the interactive to graph the datas What statement best describes the results of the clean up? Multiple Choice
1. There was a one-third drop in pollutant levels after the cleanup, with a slight increase in subsequent years.
2. The cleanup effectively removed pollutants from the river leaving only about 10% of the original amount by 2012
3. There was an approximately two thirds drop in polutant levels after the dearup, which further decreased in subsequent years.
4. The cleanup was marginally success since pollutant levels dropped by about 10%.
