The data graphed include six or seven locations from each of the three Portland Schools. The School district tested nearly 00 buildings. Is there enough data here to make any conclusions about the water in Portland schools? What about for schools A, B and C?
I believe that these graphs are enough to make a conclusion about Portland schools. For example, in the test it states, “But even low levels are not safe-just safer.” On the graphs of the schools A, B and C, every fountain contains a level of lead. 45% of the fountains contain more lead than the EPA’s action limit. This is already unsafe. Also, the pipes between the schools are most likely connected and made out of the same lead material.
2. Each school had its water tested by a different

lab. Do you think this might has affected the results of the tests? Explain your reasoning. I think that because each of the schools water is being tested by different labs, the results will be somewhat different.
They may have different methods and ways of testing that water. Also, school A shows that it has more lead than schools B and C. Maybe the lab that tested school A had a more precise test.
3. Based on the data presented in the graphs, how do you think each school should respond to the results of the testing? Should students drink the water in the school? Explain your answer.
These schools each have at least one fountain that was over the EPA’s action limit. They could replace the pipes. However this could be expensive.. They should take away at the fountains so the kids don’t keep drinking the schools water. Even though the fountains with less leas are safer, over time more and more lead will damage the kids bodies (as it explained in the article).
4. If the water was tested again at each fountain, might the results be different? Explain your answer.
The results of the second could be much different than the first test. For example, in the text it explains how when water sits in the pipes for a long period of time, it gets more lead in it. As a result of this the tests would be different because the water could have sat in the pipes over summer or the schools could have continued to use the fountains the same amount of time, so there would be the same amount of
lead. 5. How else might you present this data? These are many other ways you could represent the data of the lead in schools A, B and C. You could use a number line, dot plot, or histogram.
The main problem was lead, with seven well samples showing up positive. The calcium and nitrates both had four samples showing up positive. Hydrocarbons had 3 samples showing a positive. Heavy metals have two positives,and bacteria had only 1 positive. Many men, women, and children are getting sick from horrible water pollution and some of the water pollutants cause cancer! So through all thirty of the tests we ran we got twenty one samples back that gave us a positive result. In conclusion the water in Hickory Hollow is justified, showing various
Two public notification clauses exist in the LCR. First is the Lead Consumer Notice, according to 40 CFR 141.86(g), lead testing results must be sent to consumers of the water supply within 30 days regardless of whether the AL was exceeded. Second is the Consumer Confidence Report, 40 CFR 141.154 sta...

This would give us an extra measure of accuracy each time. Another way to improve the experiment and to produce consistent readings was to used distilled water. This is because the distilled water contains no impurities and therefore no hardness in water.
This is why the Flint water crisis is so critical today. Because young children are being exposed to lead and they should actually be screened from the lead. The pipelines with lead in the water system and the whole community of Flint, not being able to drink water out of the facet as well as not being able to
Thomas Jefferson was a man who believed that all American citizens need to be educated so that they may exercise their rights. He saw public education as essential to a democracy. One proposal he made for public education would guarantee that all children could attend public schools for three years. However, much like other early school reforms, this proposal received much rejection and was never brought into being. Despite this rejection, Jefferson still believed that America needed public education. Eventually, he opened the University of Virginia. Even though his bills and proposals to benefit public education never saw the light of day, he still made many contributions to public education by providing the foundation on how a democracy should handle educating its
The organization I work for is a nursing home management company. That’s the simple definition. Health Services Management Group manages of the operations of eleven (11) skilled nursing facilities (SNF), and three (3) home health agencies (HHA). Each of the SNFs and HHAs are operated/licensed by a single purpose entity. Of these long term care providers, one (1) SNF and two (2) HHAs are operated as non-profit organizations. The purpose of the non-profit providers, ultimately, is to fund The Trousdale School. “Trousdale School serves high functioning adults with intellectual disabilities, providing academics and life skills for the purpose of learning independence.” 1
They are concerned that their kids are getting too much lead in the bloodstream because they have been drinking the tap water.
Evaluation: If this experiment was to be redone then more diverse oceanic life would have to be used playing different roles in the water. The experiment performed showed a small projection of the ocean’s course if pH levels rise but by adding more confounding variables then maybe the outcome may have been different. If another researcher is to replicate this experiment it is optimal if they did several different trials to see if the same result occurs like the one just performed.
... water crisis will have a long term affect on those who are consuming this water on a daily basis. Lead attack the brain and can cause coma and possibly death. Children who survive lead poisoning are left with serious health issues such as metal defects and leave a child mentally unstable. Even at lower levels of exposure symptoms such as behavioural changes such as reduced attention span, reduced intelligence quotient (IQ). Children with smaller amount of lead exposure also showed increased anti social behaviour, it also reduces educational attainment. These side effect of high lead exposure can leave children scarred for life. The water crisis in Flint Michigan car scar children for life. This could all be resolved if they could come to an agreement and replace the water pipes, allowing for cleaner and healthier water to be accessible to citizens in Flint Michigan.
I personally did the nitrate test, but there were many more tests that our group did that day. There is the nitrate test, the phosphate test, the alkalinity ppm test, the ph paper test, and our leader collected rocks to test if they can neutralize acids because that means it can resist acidity. Nitrates and phosphates are polyatomic ions that when they go into streams, they will cause overpopulation of algae and mess up the ecosystem. Dissolved oxygen is good and bad for the creek, if there is too much will kill the macroinvertebrates and too little will to. Acid rain is really bad in our area and because of that we had to test the pH of the creek. pH goes on a scale of 0-14, 0 is a very acidic reading and 14 is a very alkaline reading. Things that have a lot of alkalinity will neutralize the acid make it go to 7, which is the default reading and the reading for average water. A lot of our readings are measured in ppm, or parts per
The hypothesis for this experiment was, If three different types of waters (saltwater, fresh water, tap water) are tested, then the liquids won’t evaporate at the same rate and tap water will evaporate at the fastest rate because it won’t have any non-volatile substances to hold it back from evaporating.
As the test tubes were taken out of the water bath and placed the in
I understand that eighty years ago, kids were shorter. It makes perfect sense, less food, and not too many bovine growth hormones. In fact, it was probably considered sensible to build shorter water fountains. But why would you not feel the need to replace those water fountains years later when they only come up to kid’s knees? Hydration is a fundamental part of life. I suggest three ways to improve the drinking conditions of all students at Worland High school. To build new water fountains Worland students need to do three things, raise water awareness, earn money for new water fountains, and convince teachers to support the cause.
The 14th of December 2013(Saturday) was the day when this fieldtrip was organised .it was a pleasant day, our whole class of grade 10 evm students (25 students) got ready and we head out for wazirabad Delhi. We had decided to go to three places and collect water samples so that we could conduct different tests on samples such as:
