SOUTH KINGSTOWN, R.I. (AP) - A study by University of Rhode Island oceanographers has found that nutrient levels in the Narragansett Bay are half what they were in the 1900s.

The Providence Journal (https://bit.ly/1TZtojc ) reports that the decade-long study says the lowered levels have resulted in clearer water and fewer algae blooms.

It focused on discharges from 11 state wastewater treatment plants, which are the main source of nitrogen. The nutrient feeds algae and can ultimately lead to low oxygen levels in the water.

The study was led by oceanography professor Candace Oviatt, who says people have been astonished by how clear the water is.

Regulations enacted after a massive fish kill caused by a lack of oxygen in Greenwich Bay in 2003 called on treatment plants to reduce nitrogen discharges by 50 percent.
