1.) Humans tend to the livestock, the livestock produces manure which fertilizes crops, and humans eat the crops, then humans give off waste. :)
2.) Nitrates in water are hard to get rid of. If you boil water then the nitrates in the water become more concentrated. Then you just get blue babies. Poor people can't afford purification.
3.) Chlorine kills off bacteria in water which is caused by manure and foreign objects.
4.) Laws in Iowa are prety well set. Although, we do think Iowa should be more strict on the chemical consumption. Buisnesses get away with too much illegal chemical manufacturing. There should be a set amount on chemicals which each buisness should be able to obtain.

1. How are sewage plants, manure management planning, and rural water safety related? What things do all of them need to do for human health?---They all contribute to making sure the ground water is safe for people to drink.They all need to control what goes in and near water
2. Why is chemical runoff a big problem for water purification? Think, particularly, of nitrates (but we could apply the same idea to mercury accumulation or non-point oil pollution), and the difficulties people encounter in Iowa wells.--Some chemicals are hard to purify
3. What is the value of chlorination in trying to manage potential problems that show up in #1?---chlorine helps break down harmful chemicals
4. What types of regulation should we have (in your opinion) in Iowa for the issues in #1? Are laws in Iowa, as you understand them, too lax, too strict, or just right?--we should have laws where you can only put on fields at certain times of the year otherwise fined or more taxes. our laws are just right the way they are

1. They all deal with how we keep our water for use clean. They all have to keep our water clean so it is healthy enough for us to drink.
2. Chemical runoff can run into the water and into tiling causing our water to have high traces of chemicals, which are unsafe for us to drink. If runoff is bad enough it can get into wells and contaminate all of someones drinking water.Waterways have started to be created to catch the nitrites and nitrates from getting into streams.
3.Chlorination is the most commonly used technique to disinfect drinking water. Chlorine can kill all the bacteria in the drinking water, but it can't kill viruses, cysts, or worms.To maximize the use of chlorine, you need to also use filtration.
4. We think we should filter every source of drinking water we use. In Iowa they already regulate and regularly test for harmful chemicals. We think the laws for drinking water in Iowa are just right.

3. chlorination is valuable because it can kill harmful bacteria if contamination is a problem
4. i think chemical runoff needs to be regulated more closely because it seems too many chemicals are used. farmers should steady off the chemicals or just moniter their runoff better

1. they all provide safe drinking water. They need to purify poo water.
2. Because it contaminates the water and makes it unsafe for use.
3. The value is less poverty and a healthier human health.
4. We should have a regulation of our water to be of high quality, perhaps our laws in place right now are just right. We enjoy having our extremely chlorinated (clean) water.

1. they all try to purify the water as much as possible. They all need to remove as much nitrates as possible.
2. We are getting dangerous chemicals in our water, if there is too high of an amount of nitrates in the wells it can kill children as young as 5.
3. Chlorine kills chemicals, but too much can be bad for you.
4. too lax, some farmers let their cows go in the creek and it contaminates the water for everyone downstream, there should be mire strict laws about where your livestock can roam.

1.They're all protecting water and soil safety
2.It would be too hard to get the nitrates out of the water.
3.Chlorine kills the bacteria
4.We believe the laws are just fine and we don't have too many issues with water pollution

1. How are sewage plants, manure management planning, and rural water safety related? What things do all of them need to do for human health?
All of them need specific locations and guidelines to make them run efficiently and effectively. Manure and sewage plants need to be away from the rural water plants to prevent cross contamination
2. Why is chemical runoff a big problem for water purification? Think, particularly, of nitrates (but we could apply the same idea to mercury accumulation or non-point oil pollution), and the difficulties people encounter in Iowa wells.
Chemicals dissolve and stay dissolved in water more easily than just sediment because they were designed to permeate the ground and stay there so it is difficult to filter.
3. What is the value of chlorination in trying to manage potential problems that show up in #1?
4. What types of regulation should we have (in your opinion) in Iowa for the issues in #1? Are laws in Iowa, as you understand them, too lax, too strict, or just right?

1. They are all related because they all involve trying to keep water safe.
2. Because if chemicals runoff into rivers or into underwater water tables the whole cycle for groundwater is affected. if a little bit of the water is infected, a whole bunch of it will be soon affected and unsafe for use.
3. chlorine will clean the water, but it leaves a taste in the water that many people do not like
4.We think they're are pretty good. We think they could be stricter. Anything can be improved so I don't think this is any different. We should educate the community more than figure out if we need more rules.

They all have to do with maintaining clean safe water for people to use. The chemicals are washed away with the rain water and flows into our drinking supply, if there is a crack in a farmers well the chemicals can get in their wells and make nitrate levels high or chemicalizing the water. Putting chlorine in the water will help purafiy the water,but will give it a different taste to it. the laws are perfect!

1)If you don't put the manure management plant in the right location, then it could contaminate the water. if sewage plants don't confine the sewage, then it contaminate the water and affect our health.
2) If nitrates were in the water then it is harder to purify.
3) Chlorine kills bacteria.
4) The laws are not strict enough. There should be more regulations on manure management, fines, or taxes.
