b. people living downriver of these cities were more likely to experience contamination of their drinking water sources.
<h2>Further Explanation</h2>
Stormwater is rainwater that is not absorbed by the ground and then flows on roads, roof tiles, and so on. This water runoff is dangerous because it contains pollutants, including heavy metals, bacteria, oil from vehicle oil spills, solids, and nutrients.
Various stormwater control measures (SCMs) are used to increase infiltration during rainfalls and reduce discharge to stormwater drains or sewer systems. Stormwater basins are one of the most common methods for receiving stormwater, and there are several different designs that can be used. The setting is a basin and a lower surface retention chamber with perforation pipes and gravel to store water, while other designs use natural soil. Some basins include wetland plants to help maintain water and in other parts are dry even though a lot of grass has been mowed.
Some issues of controlling stormwater with physical performance (not water quality) can be overcome with low-cost monitoring techniques. Although low-cost monitoring does not provide much quantitative information about performance, it is an appropriate first step. If necessary, follow-up using high and more detailed cost monitoring can be done.
