Four Corners River Health Workshop recap: ‘The Animas knits everything together’ — Ann Oliver


From The Durango Herald (Dale Rodebaugh):

Two hundred people involved in water-quality issues from Silverton to Northern New Mexico described projects, compared notes and asked questions of others Tuesday. The occasion was the Four Corners River Health Workshop sponsored by the New Mexico Environment Department in collaboration with the Animas Watershed Partnership and the San Juan Soil & Water Conservation District…

“There are 35 community water systems and 22 permitted dischargers, including 16 sewerages,” Oliver said. “It also provides room and board for 25 of the birds, frogs, fish and mammals identified by states as species of greatest conservation concern and supports at least 10 fishing and boating recreation businesses.

“The Animas knits everything together,” Oliver said.

Additional pressure on the river is the presence of nutrients, most commonly nitrogen and phosphorus, which in excess cause algae blooms that steal oxygen needed by other fish and aquatic life. Water-treatment plants and fertilizer from agriculture are major sources of nutrients, she said…

Peter Butler, chairman of the Colorado Water Quality Control Commission and a member of the Animas River Stakeholders Group, said new nutrient standards will affect Front Range dischargers long before smaller water-treatment plants such as Durango must upgrade equipment to meet standards.
