DENVER, April 5 —The Metro Wastewater Reclamation District has signed a contract with the US Geological Survey for a continuation of the independent monitoring program at the 52,000-acre METROGRO Farm in eastern Arapahoe and Elbert Counties.
This monitoring program was developed based on the current USGS monitoring program, which has just ended. The new monitoring program runs April 1, 2012, through December 31, 2014.
The new program covers monitoring water quality conditions in eight wells on or near the METROGRO Farm. Five wells will be sampled quarterly and three will be sampled annually. With each sample, depth to water, water temperature, specific conductance, pH, dissolved oxygen concentration, and acid-neutralizing capacity will also be measured.
Stakeholders involved with the Metro District’s biosolids management program also provided input to this plan’s development.
“Based on data collected at our farm for almost 20 years, we have seen no negative effects from using biosolids as a fertilizer and soil amendment,” said Alicia Gilley, director of the Metro District’s Resource Recovery and Reuse Department.
“As in the past, the data we collect will continue to be made available to the public via the USGS NWISWeb database.”
The Metro District is the largest wastewater treatment agency in the Rocky Mountain West. The Robert W. Hite Treatment Facility at 64th and York treats about 140 million gallons of wastewater a day. The service area includes nearly 1.7 million people and encompasses approximately 715 square miles, including Denver, Arvada, Aurora, Brighton, Lakewood, Wheat Ridge, Thornton, and part of Westminster, together with about 40 sanitation and water and sanitation districts in the metropolitan Denver area.
