Answer:

The town should find a new source of water.

Explanation:

Step 1: Convert the mass of copper to milligrams

We will use the conversion factor 1 g = 1000 mg.

0.002 g × (1000 mg/1 g) = 2 mg

Step 2: Convert the mass of solution to kilograms

We will use the conversion factor 1 kg = 1000 g.

1000 g × (1 kg/1000 g) = 1 kg

Step 3: Calculate the concentration of Cu in ppm (mg/kg)

2 mg/1 kg = 2 ppm

This is over 1.3 ppm, so the town should find a new source of water.
