Introduction: Iron and manganese arrive in water when water breaks down minerals in rocks and soil. Iron and manganese comes from the earth's crust. These elements are not hazardous but could cause problems. When a person receive too much iron, the disorder is called Hemochromatosis and symptoms of this include heart disease, diabetes, cancer and etc. Iron and manganese could be removed by treatment. Another choice is to relocate the well. When a large amount of iron and manganese is greater than 10mg/l, chemical oxidation is used using a sand trap filter. Another option is by adding potassium. It take about 20 minutes to oxidize the water. And using potassium option it is a more effective way of oxidizing the water and lowering the pH of it too. We tested the water fountain in School of the Future to see if iron and copper was in the water. Methods: 1.Measure a 5ml water sample in the calibrated tube. 2.Add 5 drops of Iron Test Sol.#1 3.Add 1 level spatula of Iron Powder to the sample. Replace the cap and mix to dissolve. 4.If iron is present, a wine red color will develop. Allow 2 minutes for full color development. Result of Experiment: We tested the water in the water fountain at School for Iron. By filling a cylinder up to 5ml and adding Solution #1 of 5 drops into the Water and one layer of Indicator Power which is Solution # 2 which is supposed to change to the color red. It did not so it did not have Iron in the water. So the school fountain water we tested didn't have iron in it. Discussion: When we tested the fountain water for iron we found out at the end that there was no Iron in the water fountain. Since we found the results to be negative it means that it is a good thing because iron is bad for you IN LARGE AMOUNTS. Also iron could be found in food like coffee, and many beverages. Iron in water could affect the taste of the drink and how it looks like. It couldn't cause any kind of diseases like heart disease, or hemochromatosis because there's no iron in the water. So this means that no iron broken down from minerals got into the water. But if there was iron in the water and the water had a high pH we would use the potassium method.. The pro of not having iron in the water is that it couldn't stain your clothes because if you spill water containing iron it is not be removable and by using chlorine bleach it could even make it worse. By having iron in the water it would make be expensive trying to remove it. It takes about 20 minutes to lower the pH of the water. Iron is similar to nutrient cycle because iron comes from the atmosphere and iron and manganese goes into the water after minerals are dissolved. Errrors analysis: During the experiment we were suppose to put 5 drops of Iron Test Sol. #1 in the water only but I put one drop more so it might have effected the result of the experiment.

Is there copper in the water?

Introduction: Copper pipes are the causes of copper getting into the water. Copper doesn't get into the water naturally like the iron. The body needs copper but in small amounts of it. If the body takes in high levels of copper than needed it could cause nausea, vomiting, diarrhea and stomach cramps. Copper at high levels would cause the water to taste bitter and cause blue-green stains on the plumbing fixtures. When there's copper in the water, it causes corrosion. But if the water is not corrosive then hard water minerals would be deposited in the interior of plumbing and the calcium carbonate would protect the pipes, and it would take up to 5 years for the calcium carbonate to soften the water. Options to remove the copper from the water at individual households is to first flush the water system. In other words let the water run for awhile before using, especially if the water haven't been used for 6 hours or more, before the water could be used to drink or for cooking. Hot water taps couldn't be used either because it would dissolve the copper more faster. But if the water has a low pH, a neutralizing filter can increase the pH of the water. This option could eliminate the corrosion problems. Methods: 1. Fill a chemplate cavity approximately 2/3 full with a sample of the water. 2.Add 1 drop of Copper Test#1. Mix and allow to stand for 1 minute. 3.Add 2-3 drops of Copper Test Sol. #2. Mix and allow to stand at least 2 minutes but not more than 10 minutes. 4.An orange colored solution indicates the presence of copper. Result of Experiment: After we finish testing the water, it was suppose to change to a orange solution it there were copper in the water was negative. Discussion: We tested the water fountain in school for copper and the results came out negative, Because the result is negative it means that it couldn't give students any symptoms like nausea, vomiting, and diarrhea. But the bad thing about finding the water negative is that the body need a small amount of copper. If there were EXCESSIVE copper in the water we would use the reverse osmosis and distillation treatment because it is the only option to remove copper from drinking water, one faucet at a time. Both component sulfide and chlorine is similar to copper because they don't get into the water naturally. Copper connects to water hardness because when copper get into the water it could cause corrosion and it causes the water to be a good buffer. A good thing about not having copper in the water is that it could cause the pipes to have blue-green stains on the plumbing fixtures. It would take a long time to remove the copper from the water since the only option to remove copper from the water is to use the reverse osmosis and distillation treatment. It can remove the copper out of the water one faucet at a time. Copper is similar to the carbon cycle because a person needs copper in their body so after a person dies the copper the person took in will go back into the earth. Error analysis: When we were testing the fountain water for copper, we saw a piece of hair inside and that could have effected the result. |
