From The Canyon Courier (Joe Moylan):
The Jeffco Board of Public Health has announced it will hosting a meeting with the Indian Hills community to review and discuss the Indian Hills Groundwater Water Quality Modeling Project Report.
The meeting, an initial step of a community engagement process around groundwater quality issues in Indian Hills, will take place at 6:30 p.m. Oct. 4 at the Indian Hills Community Center, 5381 Parmalee Gulch Road.
In 2015, the Board of Public Health contracted Dr. Margaret Herzog, a professional engineer with PH Associates LLC in Lakewood, to develop a groundwater model of the Parmalee Gulch basin using available data to evaluate the impact of existing and potential new septic systems on groundwater, according to a Jeffco Public Health news release. The purpose of the modeling study was to integrate more than 40 years of research in the Turkey Creek watershed and Parmalee Gulch sub-basin, conduct advanced geospatial analysis, and to determine if and how planned and potential development might increase nitrate pollution in groundwater, which serves Indian Hills private wells and the Indian Hills Water District’s public wells.
In Parmalee Gulch, groundwater serves as the primary source of drinking water for many residents of Indian Hills, a residential community of approximately 1,200 people, the release stated.
To protect the groundwater system, a prohibition of septic systems on certain lots in Indian Hills was instituted in 1979 by the county because of elevated nitrate pollution from septic systems in the groundwater, the release stated. Using existing water quality and land-use data, along with simple modeling methods, the modeling project was designed to inform future public health decision-making related to groundwater quality in Indian Hills.
In August, Jeffco Public Health released the Indian Hills Groundwater Water Quality Modeling Project Report to the public and requested written feedback and comments. The public is invited to submit written comments to firstname.lastname@example.org or by mail to Roy Laws, Jefferson County Public Health, 645 Parfet St., Lakewood, CO 80125.
