What happened

The record, in order.

Synagro manages sewage sludge for municipalities. A 2020 EQT announcement recorded the sale of Synagro to a Goldman Sachs fund, and described the company as managing more than 14 million tonnes of sludge a year.

In 2024 five farm families in Johnson County, Texas, sued Synagro. They alleged that sludge spread on a neighbouring field had contaminated their water sources and killed their animals. Synagro denies the allegations.

The county declared a PFAS emergency in February 2025, according to KERA reporting.

A draft risk assessment from the US Environmental Protection Agency, dated January 2025, found that sludge containing only 1 part per billion of PFOA or PFOS could exceed the risk threshold.
