New Jersey Parcels and the Toxics Release Inventory (TRI)

A quick work around from aggregating all the state parcels is to just select the parcels that intersect with TRI point locations, and merge those selected boundaries together.  This did work, but produced some unexpected errors that make me realize the putting together a coherent data set of TRI parcels will take some time.

1) Not all points were located within parcels. This is likely because of geocoding that links addresses to a street location.  In this example, the street location itself is not within a parcel.



One way to work on verifying the results would be to a) link all the parcel data with the tax data, so I can find the name and street address for each parcel (not just parcel number), and b) compare the tax data with the TRI point data to make sure the point addresses match each parcel.

This is a lot to do for all parcels.  It might make more sense to sort and study the locations with the largest emissions first, and connect and verify those locations in relation to the parcel data.

2) Another problem is that some parcels have multiple points.  This requires further investigation.



The merge of select parcels that intersected with TRI point locations created a new data set with 242 parcels.  The largest parcel, 0808-8-4 is shown above.

I was hoping that a map of top five hazard score emitters might help me identify the regional locations to focus on first, but they are distributed all across the state.  Newark is an area I've become more and more interested in as a region with numerous environmental justice concerns, so it might make sense to focus there first: Essex County.
