1. Calculate the concentration in ppm by converting the given 0.005 grams of lead per liter of water into parts per million, which resulted in 5 ppm. Since this is much higher than the EPA's maximum allowable level of 0.015 ppm, it is unsafe for drinking water.2. Compared the calculated concentration of 5 ppm with the EPA’s maximum allowable lead concentration of 0.015 ppm, and since 5 ppm is significantly higher, it is determined to be unsafe for drinking water.3. The final answer is "No, the concentration is not considered safe for drinking water" because the lead concentration in the river water (5 ppm) exceeds the EPA's maximum allowable level of 0.015 ppm, making it unsafe for consumption.4. Calculate the concentration in ppm by dividing the mass of lead (0.005 grams) by the mass of water (1,000 grams), then multiplying by 1,000,000, which gave me 5 ppm. Since this is much higher than the EPA's maximum level of 0.015 ppm, it is unsafe for drinking water.
