Answer :
Sure! Let's go through the given water quality data step-by-step based on acceptable levels and specific measurements for both tap water and outdoor water.
### Step 1: Understanding Acceptable Levels
1. pH Levels:
- Acceptable pH range: 6.5 to 8.5
2. Total Alkalinity:
- Ideal value: Around 150 mg/L
- There is no strict maximum contaminant level for alkalinity, but 150 mg/L is considered ideal.
3. Total Hardness:
- Acceptable levels: Below 500 mg/L (500 ppm)
### Step 2: Provided Measurements
1. Tap Water:
- pH: 7.2
- Total Alkalinity: 160 mg/L
- Total Hardness: 350 mg/L
2. Outdoor Water:
- pH: 6.8
- Total Alkalinity: 140 mg/L
- Total Hardness: 420 mg/L
### Step 3: Comparing Measurements Against Acceptable Levels
1. Tap Water:
- pH: [tex]\(7.2\)[/tex] is within the acceptable range of [tex]\(6.5 \text{ to } 8.5\)[/tex]
- Total Alkalinity: [tex]\(160 \, \text{mg/L}\)[/tex] is near the ideal value of [tex]\(150 \, \text{mg/L}\)[/tex]
- Total Hardness: [tex]\(350 \, \text{mg/L}\)[/tex] is below the maximum acceptable level of [tex]\(500 \, \text{mg/L}\)[/tex]
2. Outdoor Water:
- pH: [tex]\(6.8\)[/tex] is within the acceptable range of [tex]\(6.5 \text{ to } 8.5\)[/tex]
- Total Alkalinity: [tex]\(140 \, \text{mg/L}\)[/tex] is near the ideal value of [tex]\(150 \, \text{mg/L}\)[/tex]
- Total Hardness: [tex]\(420 \, \text{mg/L}\)[/tex] is below the maximum acceptable level of [tex]\(500 \, \text{mg/L}\)[/tex]
### Step 4: Conclusion
Based on the measurements provided:
- Tap Water:
- The pH value (7.2) is within the acceptable range.
- The total alkalinity (160 mg/L) is close to the ideal value.
- The total hardness (350 mg/L) is below the maximum level of 500 mg/L.
- Outdoor Water:
- The pH value (6.8) is within the acceptable range.
- The total alkalinity (140 mg/L) is close to the ideal value.
- The total hardness (420 mg/L) is below the maximum level of 500 mg/L.
Hence, both tap water and outdoor water meet the acceptable levels for pH, total alkalinity, and total hardness as specified.
### Summarized Results
