this is al jazeera america, lye from new york city new questions about possible long term threats to the water supply after more than 3 million gallons of toxic waste leaked from an abandoned gold mine in colorado. the sludge has now traveled more than 1,000 miles. so far, park officials say preliminary tests on the river have found little if any danger to fish or wild life. now the epa is testing the water downstream from the spill site. a process that could lead to san juan rivers close for another week. residents and businesses should still remain cautious. >> avoided showering any type of body contact with that water. don't let livestock drink it.

>> where i li, living off the well. >> 95% of my business has been swept away, and we have about 23 employees that are currently out of work. today colorado river paid a visit to one of the areas. there are thousands of abandon mines in his state, he is working to make sure this never happens again. the state will work with each one, and bring those assessments up to date. there are over 20,000 mines the frame of the problem, it is significant. he says abandon mines in the west have been wreaking havoc on the environment for years. >> it is also important to understand that this pollution is something that our community has been dealing with for really decades. the head waters is a historic mining district, has been

undermediated in terms of old mine, and mine tailing piles. so this pollution has in some sense been happening for a very long time. it was trying to clean up those sources of pollution, and then trigger this very massive. i can't say way are surprised but we are saddened economically, this is a very difficult time to be suffering this type of event. and we are worried aability the long term impacts will be. >> it is not the only place in the area where problems like this can occur. >> this is an example of one disaster shine the light on a bigger problem, because it is estimated about 55,000 abandon mines like there one, many containing that toxic mix inside, slowsly leaking out into our waterways so there's already an estimate that about 40% of the headquarters of western waterways have been contaminated from mine run off.

these spills send heavy watt zero the waterways this one just happened to be a big spill, where everything was released kind of at once. because of it, led concentrations over 3,000 types overleafs one tested arsenic was over 800 times safe levels. and contaminanting like this, that can be links to cancer, birth defects even brain damage, that's the big concern. i. >> so already some of these contaminants being tested in new mexico, eventually, on to utah, and a as, toward lake powell. the hope is because the metal is heavier than the water it will settle out in a slow area we don't know how much will settle out and how much will continue on, if it gets into lake powell, the colorado river connects up that can cause other problems. now i mentioned all these mines there uh the area, the reason we have this problem, they weren't well

regulatorred until the 70's. with practices not being very environmentally friendly, and that's why there are there is so much of this toxic water in these abandon mines. even long after this spill is cleaned up, this is a widespread problem. that the government has already been working on for years, and will continue to do so, to try and improve this problem. a fourth night of demonstrations marking one year since the death of michael brown turned ugly, at least one police officer used pep ever spray monday was dubbed the day of civil disobedience, when protestors shut down a highway. good afternoon to you, andy,

given yesterday's unrest, what because the police presence like there now, what are protestors planning there today? >> during the day here, it has been quiet. only during the nights when you get these inning goes protests that can go either way. but last night, did get a little hot, but not as bad as it was the day before. last night, police told us they took a much more proactive approach, to shutting down the protests there were a number of bottles thrown at police, and some rocks thrown as well, but they managed to shut it down quickly, and calmly under the circumstances there were 23 arrests last night, but they got it under control fairly well. and during the day as you mentioned 63 people arrested when they tried to block both lanes. during rush hour, and then another 57 arrested when they tries to block the federal courthouse in downtown st. louis. those were organized day

protests nothing like that today. he thinks things are getting better, but obviously the protestors disagree. >> i wouldn't say it has t goen better, because there's been multiple incidents like the one that happened last year, mike brown's -- so i wouldn't a i it has gotten better, we just -- just going day biding living. >> we will be watching tonight to find out how the protests get, erica. >> what is the latest on the man police shot early monday morning. >> . >> an outing on sunday night when he shot, police say he was shooting at them, they fired back, and he is facing ten charges. if he survives, erica. >> all right, live for us in

little less reasonable than what hillary is proposing. >> clintons plan would been paid for by putting a cap on many issues. many economists think is crimping the u.s. economic recovery, post the financial collapse of 2008. latest figures show $1.2 trillion is owed in student debt. and 11.1% of it is delinquent. >> i believe our success isn't measures by how much the wealthier americans have. >> release add video showing what it says are real lifer examples of voters burdened by student debt, unable to buy homes or cars. student loan expert hilton smith says clinton plan is bold, but may not reach every opportunity. >> it wouldn't work for some people that need to use their earning to pay for their own
