Streets are carried only near mapped places — 39 of 185 positions have none. Blank ground here is a gap in this layer, not open land.

At 0 locations across Niagara County, material repeatedly surfaced during gamma surveys, construction, investigation, and remediation—often without a surviving record explaining how it got there.

Each mark appears in the year the finding entered the written record. 0 more are undated and cannot honestly be placed on a timeline — they are not shown here.

Every figure is an estimate, in the words of the document it came from — “approximately”, “roughly”, “estimated to be”. Cubic yards, tons and drums measure different things and are never added together. 0 of the places carry a quantity at all; the rest were recorded without one. Show every figure and its source

Chapter two

Material moved along 0 routes we can name from a document — and 0 more the record points to but nobody has yet read page by page.

There are many more waste movements in the machine-extracted text than we have checked. They will be verified over time — the next chapter shows how much is still waiting.

A line is a route, not a road — it joins where material started to where a document says it ended up, not the way the trucks went. Arrows on the edge are the 0 destinations beyond this frame: Erie County to the south, and past it Ontario, Ohio, Michigan, Pennsylvania, New Jersey, Oklahoma, Utah, Louisiana and Washington State.

The tonnage above counts only movements where every load was weighed and manifested. Separately, companies told the 1979 task force they had dumped about 0 across whole decades — their own estimates, not weighbridge records, and never added to the figure above. A further 0 of clean fill was imported onto these sites; it is excluded from every total here, because material arriving clean is not waste leaving. Every figure is an estimate in the words of its source. Show every movement and its source

Chapter three

Those 0 movements are the ones somebody has read. The record points at 0 more that nobody has checked — and this is what the network looks like when you draw them all.

 

Nothing on this screen is counted. Chapter two’s figures came only from routes read against a page; these dashed ones are shown because leaving them out would make the record look tidier than it is. The gap between the two is the point.

Chapter four

At 0 places where people live, learn, worship or play, a document records industrial material being put into the ground as fill.

 

Schools, churches, parks and named subdivisions are named, because they are institutions and public ground rather than somebody’s front door. 0 more places are named in the record but have never been located precisely enough to draw. Show every placement and its source

Chapter five

Material is documented inside 0 named sewers and tunnels, each read against its page. Machine search points to 0 more sewer references still awaiting review. The Falls Street Tunnel runs through the read records of 0 separate sites — and is named in documents from 0.

Solid lines were read against the page. Dashed ones are streets a filtered sentence names beside a sewer and a material, and nobody has read them yet.

Chapter six

0 companies were named across 0 published court opinions over waste in Niagara County, in 0 separate cases — from   to  . Meanwhile 0 places in the county are on a government cleanup list, across 0 programmes.

The subject line in each popup is a topic read off the language of the opinion — we hold no pleadings. A cleanup diamond is a place on a state or federal remediation programme, counted as a place: the gallons in these records are treated water, recovered groundwater and tank capacity. Records sharing one coordinate are drawn as one place0 records over 0 places. A diamond appears in the year of the earliest document we hold — an upper bound. 0 have no dated document and arrive once the clock has run out. Show every case and its citation
