The U.S. Environmental Protection Agency’s Lead and Copper Rule regulates the presence of lead in drinking water. Under the rule, if more than 10 percent of samples test above 15 parts per billion, the federal lead “action level” is exceeded. An “action level” exceedance triggers mandatory requirements that a water system must perform. For Newark, these requirements include water quality monitoring, corrosion control treatment, source water monitoring and treatment, public education, and lead service line replacement. Newark must treat its water to guard against corrosion (pipe erosion and damage) to minimize lead “leaching” (when lead is dissolved from pipes or fixtures and transfers into the water) or flaking of small lead particles from pipes or fixtures into tap water.

Vulnerability and resilience in this artifact are defined by the high concentration of child poverty in Essex County. They are measured using the Census from 2000 and 2015 which show how there is a trend in the percentage of children who expereince poverty within the county. Majority of the children living in poverty are currently living in heavilyu concentrated poverty neighborhoods like Newark, Irvington, and the Oranges. Although the affluent town of Milburn is nearby, it is unclear how these children continue to live below the poverty line in Newark even though the towns are only 6 miles apart. 

The hazard in this artifact is in relation to the polluted water system throughout urban New Jersey areas. The Passaic Valley Sewerage Commission and the D.E.P are working together to create new infrastructure upgrades to the local sewer systems. This long term plan will help limit the amount of toxic waste that runs off into the drinking water for surrounding urban communities. 

There are many vulnerabilities listed in this artifact that directly affect the community. To begin with, Bergen, Hudson, and Essex county are listed as the state's worse air quality. It also states that more than four in 10 people experience unhealthy air quality in the community within NJ.  

The object of this study is to demonstrate with objective data that pollution in Newark is causing real damage. Especially for children, because they suffer from respiratory diseases such as asthma; which is more harmful to a developing organism like a child. It is important that we become aware that pollution damage is real, and that a part of the population that is really affected is the youngest.

I think it is an important step, clearly for presenting complaints, the problem will not be solved; we should all do it if we see something of this kind. In addition to the complaints, there are many steps to follow, such as organizing protests, taking care of daily consumption or becoming aware that a sustainable life is better for everyone.

The product used to measure the level is a portable air sensor; This product is an innovative development because as it says in the article Molly Greenberg allows to obtain air quality data, this is clearly a breakthrough since years ago getting this information was not possible or the process was much more complicated.

This artifact states the solutions that local lawmakers have come up with in order to effectively clean up the toxic waste in the Passaic River. There are many sources of resilience here as the E.P.A added to a superfund program worth $1.38 billion to clear the city of chemicals, pesticides, and all other contaminants that deterioate the Passaic River. This plan extends into the Belleville area as well. For three decades the E.P.A has used this Superfund program to clean up the countries' most hazardous waster sites. The efforts to clean up the Passaic are a result of the intesnse cleaning of the Husdon River and Gowanus Canal in Brooklyn. 

This artifact has great relevance because it allows to control and measure the levels of contamination in the air of Newark. This is very helpful in order to fight pollution and have more data to help us maintain air sustainability. Air pollution is one of the most developed pollutions today, any technological investment that helps to have more information about this is good to combat this problem.
