What Water Defense Inc Co Altman Greenfield Selvaggi LLP does
Mission
Researching and informing members of the general public of the effects that energy industry practices have on water quality.

Program
Inactive
The first program described on its most recent Form 990-EZ.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $74k to $31k (−58%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 5 reported years ran a deficit.

92% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $453k arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been.
