The so well-known Gowanus canal is one of those unique feature that only New York has: a water canal in a city. Although it is a man-made canal it is fascinating to know the impact this canal had, back in the industrial era, where ships carried cargo to factories. Back in the industrial era, the canal was the most important body of water that New York had which led to a new lifestyle to the borough of Brooklyn. The present history about this canal is not as enthusiastic as it was before, we can now the leftover problem that the industrial era left to Brooklyn. Along the shore of the canal a lot factories sat around, some of which you can still see today. Some of this factories fabricated cement, some other where a lot more contaminating like gas plants. In these days we can perceive and even physically see the problem that the canal is facing. The Gowanus canal is considered as the most polluted and contaminated in the United States. Back in the days when there was no sewage system in Brooklyn people used to throw in their waste into the canal. Many people might think that those factories around the canal are the causes of the huge contamination but, the factories are only part of it. Ages before the revolutionary era there was the transatlantic commerce, were people of every type of ethnic, specially slaves, were brought here to forcedly work while some other come searching for new life and things. As known this people where not treated like humans, many of them died of whatever disease it may be but, the point is that some of this bodies were thrown in the water. Another huge problem and hard to resolve is the sewage system in the Gowanus. The problem is that the sewage drain connects to the canal and not all of it goes to the treatment plant. At the end my concern is: is the canal ever going to be a free pollution water body. Knowing that the most pollution is not on the surface of the water but in the bottom makes me doubt sometimes, just because how hard it will be and the amount of money that this project will take. On the other had is the government willing to pay the remaining balance for the project. Indeed, the fact that to remove all that amount of is a process of years and the plan they have is to cover with multiple layers the contaminated sediment, seem like an idea that will temporarily work. The reason why I think this method won’t work is because of the fact that in case of a flood the canal water will start to flow removing all layers little by little. There are organization that have been pushing for the cleaning project but, nothing seems to happen.  The challenges to remove pollution from these waters are infinite and arduous.
