Question

3. Dr. Brown has hypothesized that wetland plants will take up common pollutants from municipal wastewater that are not completely removed during the treatment process. The wastewater is typically discharged directly into a creek. She constructs a wetland just downstream of the treatment plant and pumps a portion of the discharge water through the wetland. After moving through the wetland, the water will eventually make it to the creek. Dr. Brown measures the concentration of three common pollutants in the wastewater before it enters the wetland and again at the end of the wetland prior to discharge into the creek.

Are Dr. Brown’s methods quantitative, qualitative, or semi-quantitative?

Explanation / Answer

This is a quantitative assessment. The concentrations of the three common pollutants are measured in values, this belongs to the category of quantitative assessment,
