BASELINE HYDROGEOLOGIC CHARACTERIZATION

Characterizing and Monitoring for Compliance

Wenck’s hydrogeologists have completed baseline characterization investigations to design and install groundwater monitoring networks and define aquifer characteristics for proposed landfills, mines, underground storage tanks, and other industrial facilities. We guide our clients through the regulatory process, advocate for reasonable and appropriate monitoring levels based on existing regulations, and secure the necessary permits for the projects. We can also assist you with groundwater and geochemical modeling, and develop reclamation plans for post project restoration and monitoring for industrial, manufacturing, and mining projects.

GROUNDWATER SUPPLY AND DEVELOPMENT

Finding and Delivering the Water Supply

A sustainable groundwater source is essential. Wenck provides a wide array of professional services for groundwater resource planning, development, and management. Wenck’s hydrogeologists have sited wells and developed supplies to provide sustainable quantities of high quality groundwater for municipalities, small communities, subdivisions, private individuals, and industrial and mining clients. Our experience includes the well siting, permitting, design, bidding, hydrogeologic logging, construction management, development, and test pumping of water wells completed to depths of less than 100 feet to more than 3,000 feet. Wells have been completed in complexly faulted and folded terrain, fractured aquifer systems, karst limestone, fractured basalt flows, sedimentary rocks, and alluvial aquifers.

WATER RIGHTS AND PERMITTING

Getting and Keeping the Right

At Wenck, we take your right to the use of water seriously. We understand the importance of groundwater or surface water for your needs. With former state regulators on staff, Wenck has been involved in literally thousands of water right proceedings. We understand the water right process and have worked closely with engineers, attorneys and state water right programs. Our staff can help you identify and evaluate a potential groundwater or surface water supply, complete the water right application process, walk it through the regulatory maze, and represent your interests in court as an expert witness. Wenck can also acquire the necessary permits for each water supply project. As water supplies become more limited, having someone who’s been there done that is crucial to project success.

WATER WELL DESIGN, BIDDING, AND CONSTRUCTION MANAGEMENT

Optimizing for Long Term Production

Delivering a successful project begins with well siting and ends with installation of the appropriate pumping equipment. Based on your project requirements and our knowledge of the local aquifers, we design our wells and wellfields to accommodate the pumping equipment necessary to obtain the requisite water as efficiently as possible. Our experience and knowledge of the well design and construction process allows us to develop bid packages and contract documents that incorporate the highest level of technical expertise. Wenck can solicit public or private bids from qualified water well drilling professionals and prepare engineer’s estimates of costs. During drilling and well construction, Wenck’s hydrogeologists collaborate with the contracted drilling professionals to see that the wells are completed to our high standards. By logging the drill cuttings, observing drilling conditions, providing the final well design, guiding well development, and completing the aquifer tests, Wenck provides the services that are crucial to the long-term success of the project. Test pumping of completed production or recharge wells is critical to evaluate the maximum sustainable yield of each well, develop pump design criteria, and provide baseline well data for future maintenance and rehabilitation.

GROUNDWATER MODELING

Predicting Future Outcomes of Conceptual Plans

Wenck has the experience and expertise in developing analytical and numerical models to evaluate groundwater scenarios for project planning and design. Depending upon the rigor required to answer your groundwater questions, model development and calibration efforts can range from complex and intensive 3D Modflow models, to simple Theis analysis or spreadsheet models using analytical approximations. Models developed by Wenck’s skilled and practical hydrogeologists can help you understand the groundwater flow through the site, estimate influence of existing pumping wells on proposed nearby wells, groundwater – surface water interactions, predict pumping rates, wellfield layout design, dewatering impacts on neighboring wells or contaminant plumes, contaminant fate and transport, and predict impacts on water levels under various pumping scenarios.

DEWATERING SYSTEM DESIGN

Removing Nuisance Groundwater

When groundwater must be removed to accomplish your goals, Wenck’s hydrogeologists can design a dewatering system to facilitate the completion of your project. Our staff has designed dewatering systems to facilitate the installation of water supply pipelines, to assist in the construction of buildings, to allow for mining of aggregate resources under dry conditions, and to drain shallow groundwater from residential subdivisions for the installation of basements. Wenck’s designs are based on the geology of your site, and a solid understanding of its hydrogeologic conditions. Test pumping of the aquifer is typically required to identify groundwater flow conditions and to provide the data necessary to complete the design.

GROUNDWATER CONTAMINANT MONITORING AND REMEDIATION

Finding, Assessing Risk, and Fixing the Problem

Wenck combines engineering and hydrogeologic expertise in groundwater remediation to cost-effectively assess and mitigate environmental contamination. Wenck will characterize the extent of the problem, determine the options for mitigation, negotiate with regulatory agencies, and implement the approved plan. Wenck has an impressive history investigating, designing and constructing remedial systems for sites with groundwater contamination. Wenck delivers cost-effective, risk-based solutions to save time and money while protecting human health and the environment. Whether you are performing a voluntary cleanup to make your property more marketable or mitigating environmental liability, Wenck can assist you through the entire process. Understanding today’s multi-tiered risk assessment methodologies is critical to determining the appropriate remedy for your situation.

SPRING STUDIES

Protecting our Natural Resources

Springs are vital groundwater resources that can be adversely impacted by drought or development. Wenck provides flow and water quality monitoring services to assess the discharge and quality of a spring or series of springs. These services are provided to determine whether the water source may have been impacted. Spring monitoring may be warranted due to landowner concerns regarding oil and gas development, apprehension regarding potential drought impacts, and anxiety regarding the potential impacts of new nearby groundwater development.

SOURCE WATER ASSESSMENT AND WELLHEAD PROTECTION

Securing Water Supply from Contaminant Threats

Protecting public groundwater and surface water supplies from contaminant threats is the goal of source water assessment and wellhead protection. The source water assessment process delineates your source water area, the area that contributes water to wells or surface water intakes. After the source water area has been determined, Wenck assesses the sources of contamination within this area that have the potential to affect the drinking water supply, and evaluates the susceptibility of the water supply to contamination by each of these potential sources. Wenck can then develop protection plans for the wells and intakes through collaboration with local governments and citizens. The plans outline the measures for the public water system policymakers to protect their drinking water supply. These measures may include management plans, cleanup efforts, public education, or zoning changes among other options.

WELL EVALUATION AND REHABILITATION

Bringing Back the Well

When an existing production well fails, or produces less water than when originally completed, Wenck can evaluate the well and aquifer to diagnose the reason for the decline in production, and provide recommendations to get the well back to optimal production. Our well evaluation will address the condition of the production borehole, well screen, casing, pumps, motors, piping, potential well interference, and impacts of regional and local dewatering. Wenck can also develop operations and maintenance plans that allow you to track aquifer and pump performance, reveal potential well problems before a well fails, and plan for appropriate maintenance to maintain well performance.

INFILTRATION GALLERY DESIGN

Accessing Shallow Groundwater for Supply

When surface water resources are available and suitable deeper groundwater supply options are not practical, infiltration galleries can be designed and implemented to provide your water supply. Such galleries typically include several horizontally laid well screens either below or adjacent to the river bed to obtain water from the shallow alluvial aquifer. Wenck’s hydrogeologists will work with you to identify your yield and water quality requirements, and develop an appropriate gallery configuration given the layout of the river, its flow characteristics, and your property.

GROUNDWATER RESOURCE SUSTAINABILITY EVALUATION

Sustaining Vital Resource Infrastructure

Over the past several years, regulatory requirements, drought conditions, and over-pumping have combined to lower water levels and threaten existing groundwater resources in many areas. Wenck can work with you to assess your overall groundwater use and water systems, and assist you with developing and implementing long-term water management strategies. Through careful and strategic planning, Wenck works to make the long-term success of your water supply our success.
