Cascade Earth Sciences (CES) services

Finding solutions to help businesses and communities `take the waste out of water` is what CES is all about. And thanks to our Design/Build/Operate approach, we can tailor a solution that`s right for you -- using any combination of professional design work, equipment supply, construction, and system operations. Projects using CES’ design-build approach gives owners control over quality, while greatly simplifying management.

CES provides its mining industry clients with all the water quality protection services the mining industry requires. Mining operations require reliable solutions for meeting its objectives of minimizing mining’s footprint on the environment while remaining profitable. A critical area of environmental concern for most mining operations is water quality protection. Mining operations are temporal in nature with distinct development, operational, closure and post-closure phases. The obvious objective of any mining operation is to maximize the operational phase and shorten all other phases. The length of the operational phase is defined by the size and value of the mineral resource and the cost to extract and process it. Operations can have one or more temporary closures due to periods of unfavorable economics.

Agencies and environmental managers are faced with the growing challenge of dealing with active, abandoned, and inactive mining operations, which are impacting the land that they manage. CES has extensive experience in providing a variety of regulatory driven investigations including: Preliminary Assessments (PAs), Site Inspections (SIs), Engineering Evaluations/Cost Analysis (EECAs), Remedial Investigation/Feasibility Studies (RIFS), and Removal/ Remedial Design, Implementation, and Closure.

Our approach to wastewater treatment and water reuse combines mechanical and land based systems to find the most cost-effective and sustainable solutions. We leverage our clients` site features to meet specific water quality goals. CES specializes in the design, permitting, construction, and management of wastewater treatment systems that beneficially reuse water, solids and byproducts... thereby reducing energy and capital costs, and expanding usable water resources. Land application options include use as soil amendments, an irrigation water supply, or a nutrient source for crop production. We have completed over 1,000 projects across the U.S. and internationally.

CES offers our city/county government and industrial clients a wide range of landfill services in compliance with Subtitle D and state specific regulations. We are well versed with landfill plan development, groundwater monitoring (when required), statistical analysis of groundwater quality data under Subtitle D, and geochemical interpretations. Our approach to landfill work is quality and service driven. We provide what the client needs in a cost-effective and professional manner.

The importance of understanding environmental liability on a property being considered for purchase cannot be underestimated. Environmental laws and regulations state that the current property owner is responsible for contamination that exists on their land even if a previous owner caused it. A thorough due diligence Environmental Site Assessment (ESA) is money well spent. When CES performs an ESA, we coordinate with appropriate regulatory officials and are familiar with local, state, and federal regulations associated with site remediation work.

Human activities interact with our natural hydrologic environment in many ways. As water demand grows, the need for effective management and efficient use is greater. The CES approach to water resource management challenges is to use science and engineering to create solutions that leverage natural site features to reduce cost and improve water quality.

CES provides an innovative approach to identifying and managing stormwater-related issues. Specifically, our team of hydrologists, engineers, biologists, and geologists seek resource-based solutions to assist with regulatory and permitting requirements. The following summarizes some of the specialized stormwater management services provided by CES.
