Agreement reached to improve water quality (11/24)
Nearly one quarter of the nation’s housing and commercial development depend on onsite and septic wastewater treatment systems. When properly sited, designed, and maintained, these systems perform at a high level. But between 10 and 20 percent fail each year, posing a great threat to surface and groundwater, according to EPA. Malfunctioning systems are the second greatest threat to groundwater quality in the United States.
