Question

City water management is analyzing water samples from the local river for water pollutants that could be toxic to humans if found in drinking water. Their collection data is below.


Samples

Location

Nitrates

Carbamates

1

Two miles upriver from drinking water uptake facility

12 mg/L

0.03 mg/L

2

One mile upriver from drinking water uptake facility

9 mg/L

2 mg/L

3

One mile downriver from drinking water uptake facility

8 mg/L

0.03 mg/L

4

Two miles downriver from drinking water uptake facility

10 mg/L

0.05 mg/L

Toxic levels: Nitrates ≥ 10 mg/L; Carbamates ≥ 0.04 mg/L. *≥ denotes greater than or equal to.
