1 For less accessible burst pipes, such as underground or inside a wall, it can cost $400-$1,500 or more, depending on how much work it takes to uncover the burst pipe and if the work is done on an emergency basis. 2  A Denver plumber estimates fixing hundreds of burst pipes in one winter, with an average bill of $900. If the leak is under a concrete slab foundation, just repairing the pipe can cost $500-$3,800 or more; see How Much Does a Slab Leak Cost. 2  A spot repair can put additional pressure on the remaining pipes; it might be necessary to replace everything.
The team found that Native Americans most likely had a common Siberian origin, contradicting theories that an earlier migration from Europe occurred. The timeline Rasmus and his colleagues propose goes something like this: About 23,000 years ago, a single group splintered off from an East Asian population.
The return of some Native Americans to Asia was revealed only as researchers struggled to understand their data, Reich said. Early results clearly indicated the migration of First Americans along the coast to South America, but the results for North America were more complex.
