This manual provides detailed methodology for the three most common sampling approaches used by the Agricultural Chemicals & Groundwater Protection Program for its monitoring responsibilities: monitoring well sampling with either a peristaltic pump or pneumatic bladder pump, and sampling of domestic or irrigation wells. It is expected that all field personnel have reviewed and learned the methodology contained within this manual before attempting to conduct sampling events in the field.
This document presents the guidelines for the collection of baseline water quality and overburden geochemistry data. The purpose of a baseline data-collection program is to characterize the pre-mining environment. Once collected, the data may be used to help evaluate the potential hydrologic impacts that may occur as a result of coal mining.
The State of Colorado is rapidly emerging as a leader in the electric vehicle (EV) market. According to the ZEV Sales Dashboard, as of August 2017 there were 11,238 EVs in Colorado. Over the first eight months of 2017, EV sales were up 73% over the same period in 2016. Battery electric vehicles (BEV) comprised 70% of total EV sales with plug-in hybrid electric vehicles (PHEV) making up the remainder. With increased adoption, the State of Colorado stands to reap significant air quality benefits. Under the Colorado EV Market Implementation Study's high growth rate projection, by 2030 Colorado could have close to one million EVs on the road.7 By achieving this growth rate, Colorado could experience an annual reduction of ozone forming pollutants estimated at 800 tons of nitrogen oxide (NOx), 800 tons of volatile organic compounds (VOC), and up to 3 million tons of GHG.
Social, economic and environmental impacts of proposed improvements to the Interstate 25 (I-25) corridor through the Colorado Springs Urbanized Area have been examined in this Environmental Assessment (EA).
Brandegee wild buckwheat (Eriogonum brandegeei) is a mat-forming plant in the Polygonaceae (Buckwheat Family) that is known only from the Arkansas Valley in Fremont and Chaffee counties, Colorado, and is considered to be imperiled at a global and state level. One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects.
At the request of Cherry Creek State Park, GEI Consultants, Inc. completed a study to evaluate the potential influence of companion pets and their fecal wastes on microbial soil and water quality near the designated use area. Cherry Creek 12-Mile Multi-Use Area located upstream of the reservoir, the western border of which is Cherry Creek. The most commonly cited water quality concern as related to pet waste is microbial contamination, typically related to fecal coliforms. Fecal coliform bacteria are a sub-group of the total coliform group found in the feces of warm-blooded animals such as people, livestock, wildlife, and pets.
