11. Write your conclusion about the quality of wells water, the sample was taken in June, the soil around the well is polluted, and the well with out roof.
The results of analysis
test-nil, odour-nil, transparency - 25 cm, ammonia - 0, 3 mg/1, nitrate -50 mg/1, hardness - 6, 1 mg/1, iron - 0, 2 mg/1, fluoride - 0, 8 mg/1, chloride - 28, 6 mg/1, coli-titer - 0, 1 ml.
Conclusion
The result of chemical and bacteriological analysis show a faecal pollution of the water. The concentrations of fluoride, iron and chloride are normal. Recommendation
The well must be closed for repairing and to clean the area around the well. Before consuming we have to get the analysis of the water.
12. Small village its population 258, they are using artesian water well, the quantity of water equal 700 I/hour.
The result of analysis shows: colour - nil, odour - nil, transparency - more than 30 cm, hardness - 8, 8 mg/1, chloride - 135 mg/1, ammonia - 0, 1 mg/1, nitrate - 6, 2 mg/1, nitrite - 0, 001 mg/1, iron - 0, 6 mg/1, sulphate - 285 mg/1, fluoride - 0, 8 mg/1, coli-index - 4.
Your conclusion and recommendation about sanitary situation of that well.
Solution:
In relation to the state sanitary standards of 1996. The quantity of water per person in rural area about 50 I/day. Daily quantity of water from that well is 700 l • 24 h = 16400 l or 63, 5 I/person, that is means, the water enough for the village. The analysis shows high concentration of iron, that means the water cant be used for washing the clothes.
13. Your conclusion and recommendation about pipeline water.
The results of analysis shows: test - nil, odour - nil, transparency -30 cm, hardness - 6, 5 mg/1, ammonia - 0, 1 mg/1, nitrite -0, 005 mg/1, nitrate - 25 mg/1, sulphate - 185 mg/1, chloride - 28 mg/1, fluoride - 2 mg/1, coli-index - 2.
Solution: In relation to the state sanitary standards for 1996, the results of analysis shows:
1. The physical and chemical signs are normal.
2. High concentration of ammonia, nitrite and nitrate because offaecal pollution of water. It is dangerous for health specially for children because of Metahemoglubinemia.
3. High concentration of fluoride may cause flurosis.
4. The water need for dismfection
14. Find out the amount of 25% bleaching powder for chloranation 3m3 of water in rural area.
Solutlon: 1. In rural if the water with out analysis you must use hyperchloranation method.
2. The dosage of active chlorine is 20-25 mg/1. that mean for 3000 l of water (one m3 = 1000 l) 3000 • 25 mg = 75000 mg or 75 g of active chlorine.
4. The amount of bleaching powder 100-25
X -75
X = 300 mg of bleaching powder.
15. Estimate the growth and development of 10 year old girl, living in Moscow. Somatometrical signs: height - 133 cm, weight -26, 5 kg, chest circumference - 62 cm.
