How discharged wastewater is feeding massive Hill Country algae blooms

Green mats coat what once were clear, scenic creeks and rivers, the result of algae blooms that are frustrating those who live in the Texas Hill Country.

Effluent is wastewater with its pollutants removed, also known as treated wastewater.
