The clay slurry is pumped to a settling pond
, and the phosphate is sent to a chemical processing plant where it is processed for use in fertilizer and other products.
Three months before Matugas wrote the letter, SMGC had been suspended following the discovery by the Department of Environment and Natural Resources that the Chinese firm had built a giant settling pond
on the shoreline to act as a last-stage siltation control facility.
Not only can I see the sediment on the inside of the setting pond, I can see if that settling pond

A settling pond
is a reservoir where all storm water and wastewater is directed into and stored until the solids settle to the bottom.
One hundred years ago, it served as a source of water for irrigation and livestock, but it has long been a settling pond

Ritzman said his department informed the DEQ, as is required by law, when a settling pond

were the first to develop a microbial fuel cell (MFC) that is able to generate electricity while cleaning domestic wastewater from the settling pond
of a sewage treatment plant.
According to the engineers, MFC has so far produced between 10 and 50 milliwatts of power per square meter of electrode surface -- or about five percent of the electricity needed to run one mini-Christmas tree light -- while removing up to 78 percent of organic matter in wastewater skimmed from the settling pond
of a treatment plant.
At Orenco Station in Hillsboro, using the underground StormFilter rather than building a settling pond
freed up acres of high-priced land for commercial development, saving the developer $740,000.
