>> narrator: they figured the fire had started on the floor. they were looking for evidence that something flammable might have been poured there. >> in the kid's children's room, there... they were signs of what we thought was an accelerant poured on the floor. usually accelerants will leak through the cracks on the floor and burn underneath, and the fire burns up. >> narrator: then, at the door to the porch, investigators found what they were looking for. >> there was an unusual burn pattern on the aluminum threshold plate, which indicates that something had been introduced, poured down, leaked through. we took a sample of that, and it came back as a positive sample for charcoal lighter fluid. and i'm thinking that's the first time i called it arson. >> narrator: the official state report on the fire listed 20 indicators of arson. investigators were now convinced. >> narrator: the police called in todd willingham. >> my dad told him to go down there and give a statement, and when he went and gave a statement, he talks too much. and i don't kn

narrator: without half of its water supply, the city would shut down. for nearly 40 years, new york has been in the process of constructing a solution. man: this project is water tunnel number 3. we started on this project in 1969. i'm a sandhog. i've been a sandhog for 37 years. narrator: sandhogs are the men of local 147, who work deep below the city. they began building the infrastructure of new york in 1872. from the subways to the sewers, the water tunnels to the highway tunnels, new york city thrives because of their work. ryan: you got one little hole in the ground, and nobody knows we're here. see the empire state building, right. that's 1,000 feet. so you figure, you go down 1,000. how high that is -- that's how far we go down. narrator: stretching more than 60 miles under the city, tunnel 3 is taking generations of workers to complete. ryan: i don't even want to imagine what my father had to go through. when we first started, it was a rough job. everything was dynamite. now, they have these machines called "moles." it's like a big drill, and i

narrator: atlanta is a rapidly growing urban area. its primary source of drinking water is the chattahoochee river, which also provides water to many downstream communities. but its infrastructure is dangerously old, without outdated facilities and combined sewer overflows polluting the watershed. the city faces strict consent decrees and lawsuits, along with a severe lack of funding. man: when i started working for the city of atlanta in the late '70s, we were approaching that point in time where a lot was going to be needed, in terms of rehabilitation and upkeep. most of the very large pipes were at least 80 years old. we had needs that were identified in the '50s and in the '60s and in the '70s that were deferred. woman: we are urging that we all try to find a way to overcome the obstacles and limitations that might exist. woman: when i was running for office, i met someone who knew mayor hartsfield, who, in the late 1960s, said, "i don't know who the next mayor will be, "but i know they'll have to fix the water and sewer infrastru

narrator: over 300 million people live in the united states. and each person uses an average of 100 gallons of water every day. man: what it takes to actually make clean water is somewhat a mystery to most customers. woman: so how does water get from the river into your house, or here at school? woman: somebody has to bring that water to us, and somebody has to take it away when we're finished with it. man: the water infrastructure is vital for disease protection, fire protection, basic sanitation, economic development, and for our quality of life. man: you just can't visualize all the assets that are under our feet. we have about two million miles of pipe in this nation. if you're walking around in an urban area, you're probably stepping on a pipe. man: our grandparents paid for, and put in for the first time, these large distribution systems. woman: and in many cases, it's not been touched since. man: we're at a critical turning point. much of that infrastructure is wearing out. narrator: our water infrastructure is made up of complex, underg

narrator: large amounts of rainwater can cause flooding. engineers developed two approaches to stormwater infrastructure to transport water away from the urban environment. one approach was to carry waste and stormwater through the same pipe. this combined system was less expensive than building two individual pipe networks. and stormwater was seen as a way to flush out the sewers. through the 19th century, the combined system was considered state-of-the-art throughout the world, and is still in use in many cities today. but cities constructed these systems before treatment was the standard. and even today's largest treatment plant doesn't have the capacity to treat the sudden volumes of water rushing through a combined system during rain. the plant is overloaded, and the excess rainwater, mixed with untreated raw sewage, is diverted straight into local waterways, creating a combined sewer overflow, or cso. there are over 700 communities in the united states with combined sewer systems. the other approach was to separate wastewater from sto

[narrator] clare swan is chairperson of the tribe. i just looked back at my roots and began to put them together and realized really how much of that was important to me, and i had tried to, like everyone else, change that because in order to fit-- there was a time when it wasn't fashionable to be native. you were lucky if you were blond and you were light enough that you could pass. no one was allowed to speak the dena'ina language. they didn't allow it in schools, and a lot of the women had married non-native men, and the men said, "you're american now, so you can't speak the language." so we became invisible in the community, invisible to each other, and then because we couldn't speak the language-- what happens when you can't speak your own language is that you have to think with someone else's words, and that's a dreadful kind of isolation.
