Damaging High Groundwater Response Grants

High groundwater is resulting in damage to private and public property and agricultural land in certain areas of the South Platte River Basin. This is caused by a combination of natural geology and hydrology, average to above-average precipitation, increased recharge for augmentation purposes, decreased groundwater pumping and changes to how surface water is used on the South Platte. HB 15-1178 established the Emergency Dewatering Grant Program, which directed the Colorado Water Conservation Board (CWCB) to administer funds for emergency dewatering of areas in and around Gilcrest and Sterling. After several projects under this funding source, it was determined that the area of concern needed to include the entire South Platte Basin. Section 10 of HB17-1248 provided this expansion to include the South Platte River Basin and opened up project types for construction, maintenance, and monitoring of dewatering infrastructure. SB 18-218 provides additional funds for these purposes.

Course Announcement—Spring 2018 CVEN‐5333 Surface Water Hydrology

What is this class about?

The hydrologic cycle is the heart of water resources engineering and the driving force

behind many environmental processes. In this course, we will study the movement of

water through the atmosphere, the surface, and underground, allowing us to manage

the ancient problems of floods and droughts and the modern problem of pollution. The

course will also introduce HEC‐HMS and CUHP, two common hydrology software tools.

Who should take this class?

Graduate students in hydrology and hydraulics, environmental and sustainability

engineering, or environmental sciences. Undergraduate civil engineers interested in

hydrology, now part of the Civil Fundamentals of Engineering (FE) exam, may take this

course as a technical elective after earning an A or B in CVEN‐3313.

Instructor: David C. Mays, P.E., Ph.D. (david.mays@ucdenver.edu)

Schedule: Mondays and Wednesdays 5:00—6:15 pm

Course Announcement—Fall 2018 CVEN‐5335 Vadose Zone Hydrology

What is this class about? The vadose zone, linking the earth’s surface to groundwater, is crucial in water supply and environmental remediation. This class covers vadose zone hydrology, including infiltration, evaporation, drainage, subsurface remediation, and software HYDRUS‐1D.

Who should take this class? Current and prospective graduate students in hydrology, environmental engineering, sustainability, or environmental sciences. Undergraduate civil engineers may take this course as a technical elective after earning an A or B in CVEN‐3313.

The Rocky Mountain Association of Geologists will be hosting a Career Fair on April 17th to support students and those that are seeking employment. If you can only make it for an hour of this event, we would appreciate your time. Please email staff@rmag.org by Friday, March 30th if you are interested in participating in this event.

NOTICE OF PUBLIC RULEMAKING HEARING - Tuesday, May 1, 2018

RULES AND REGULATIONS FOR THE PERMITTING AND USE OF WATERS ARTIFICIALLY RECHARGED INTO THE DENVER BASIN AQUIFERS AND NONTRIBUTARY GROUNDWATER AQUIFERS (2 CCR 402-11)

The short title for these rules and regulations is “Artificial Recharge Extraction Rules," and they apply to groundwater outside of the Designated Basins.

Groundwater Contamination and Remediation

Contaminants can have natural sources (e.g., arsenic or salinity) or anthropogenic sources (e.g., industrial chemicals, pesticides, or sewage effluent). Remediation activities include passive methods (e.g., monitored natural attenuation), ex-situ methods (e.g., pump-and-treat), or in-situ
methods (e.g., bioremediation or chemical oxidation).

The aim of this Special Issue of Water is to present new research contributions in groundwater contamination and remediation. This topic includes studies that eludicate critical processes controlling contaminant sources, transport, and fate in the subsurface environment, methods to
identify the concentration and extent of contaminant plumes, as well as novel approaches to predict and enhance the performance of remediation techniques. We encourage contributions on natural and anthropogenic contaminants, as well as emerging contaminants, such as manufactured nanoparticles or hydraulic fracturing fluids. The breadth of cutting-edge
research addressing these topics is substantial, so this Special Issue will not be able to include studies specifically focused on evaluating the human health impacts of contaminants...

Groundwater and PFAS: State of Knowledge and Practice

d1114.jpg

With contributions from CGWA Members Andy Horn and David Lipson

NGWA recently published Groundwater and PFAS: State of Knowledge and Practice, a guidance document on per- and polyfluoroalkyl substances (PFAS). The Association published the PFAS guidance document to assist members and other groundwater professionals who may be tasked with investigating the transport pathways and extent of PFAS in groundwater and surface water, assessing potential risks to receptors, or designing and constructing engineering controls to manage subsurface PFAS contamination. 

The main purpose of the document is to summarize the current state of knowledge and practice regarding PFAS fate, transport, remediation, and treatment—recognizing knowledge in this field is advancing. It also aims to summarize current technologies, methods, and field procedures being used to characterize sites and test remediation and treatment technologies.

The text is focused on characterization and treatment of PFAS in groundwater and soil. However, other media may need to be considered when conducting due diligence and all appropriate inquiries at potentially impacted properties.

This document is organized into eight sections. It was written so each section could stand alone from the others, if desired:

  • Section 1 gives an overview of the problem and summarizes the key takeaways. (Free preview available here)
  • Section 2 provides a glossary of key PFAS-related terminology.
  • Section 3 summarizes the chemistry and known human health and ecological impacts of PFAS.
  • Section 4 discusses PFAS fate and transport in the environment.
  • Section 5 discusses PFAS-specific field sampling technologies, methods, and procedures.
  • Section 6 discusses the legal and regulatory status of PFAS in the United States.
  • Section 7 discusses PFAS risk communication challenges and solutions.
  • Section 8 discusses PFAS remediation and treatment options.

NGWA members may log in and download a complimentary version of this document. The cost is $53 for nonmembers.
A print version is also available for purchase in the online bookstore with NGWA members receiving a discount.

WRI 2017-1a

Th Upper Pierre Aquifer of the Cheyenne Basin,
Northeastern Colorado, Geologic Cross Sections

By Ralf Topper, Clinton D. Meyer, Marshall Haworth, Kevin C. Donegan,
Hillary Banks, Aaron Bandler, Andrew Flor, and Matthew A. Sares

First of a two-part hydrogeologic study of the Upper Pierre aquifer within the Cheyenne Basin of northeastern Colorado consisting of a short text report with 11 plates. This report (WRI 2017-1a) is a compilation of ten regional geologic cross sections created from interpretation of geophysical logs from 200 oil and gas wells. The cross sections depict the following geologic/hydrogeologic intervals: South Platte River alluvial aquifer, Ogallala Formation, White River Formation, Laramie Formation, Fox Hills Sandstone, Upper Pierre Shale upper confining layer, Upper Pierre aquifer, Pierre Ash, Upper Pierre Shale lower confining layer.

The text, maps and cross sections can be downloaded from the DWR Homepage in the “New!" section in the middle of the page. http://water.state.co.us
