We provide services to a variety of clients in the development, permitting, engineering, and management of water supply systems including but not limited to:
- Production Well Siting Design and Development
- New Source Permitting
- Bedrock Fracture Trace Analysis
- Aerial Photograph and Satellite Image Analysis
- Wellhead Protection Studies
- Design Of Water Storage and Conveyance Systems
- Potable and Industrial Water Treatment Systems
- Water Well Redevelopment/Maintenance
Our strengths in hydrogeology, groundwater engineering, water well design, and compliance and regulatory permitting are manifest in a positive track record in siting, development and permitting of groundwater supplies in settings initially believed to offer limited water supply potential due to unfavorable aquifer conditions and/or adverse water quality. We have also provided assistance to industry in locating, developing, and managing groundwater supplies for large volume industrial process use. Complementary service areas include: Hydrogeologic and Environmental Investigation and Groundwater Engineering and Modeling.

New Public Water Supply Development & Permitting
Criminal Justice Academy - Northern New England
|
 SHA completed water supply feasibility assessment through construction, testing, and permitting of a new groundwater supply well on a 28-acre facility located in an upland setting underlain by thick low permeability glacial till and crystalline bedrock of modest water bearing potential. We sited pilot drilling locations on the basis of bedrock mapping, a review of aerial photographs, and contamination sources. The water supply development field was successfully completed in adverse winter conditions. The primary bedrock well drilling target realized sustainable yields of over 30 gpm of potable water, exceeding project needs.

Site Assessment and Groundwater Longevity Analysis
Industrial Site - Yinchuan, China
|
 SHA was retained by a U.S.-based client to perform an environmental site assessment at a manufacturing facility located in north-central China, at the edge of the Gobi Desert. The ESA was conducted to better understand the potential environmental liabilities our client may have faced if they entered into a joint venture agreement with the current Chinese owner. SHA performed a detailed reconnaissance of the facility. We also collected water samples from the facility's water supply wells, performed on-Site PCB testing of transformer. SHA provided an opinion as to how the Site could potentially be regarded by national and local environmental authorities. Our services also included an engineering analysis of the longevity of groundwater supplies to provide over 2.5 million gallons of groundwater per day for manufacturing purposes.

Water Resources Engineering Services Supporting Institutional, Commercial, and Industrial Development
Manufacturing Facility - New York
|
 Since the mid-1990s, our firm has been providing assistance to a large industrial water consumer with management and engineering of process and potable water supplies. Current water usage is approximately 3.5 million gallons per day (MGD) for potable and high quality industrial process needs, or the equivalent demand of a city of 50,000 people. Water use is projected to more than double to support new industrial production and potable needs for the expanding workforce. SHA's work has included:
· New Source Development - Siting, constructing, testing, and permitting new large diameter water supply production wells;
· Wellfield Management - Application of a three-dimensional numerical model of the regional bedrock aquifer to aid in developing wellfield management strategies to increase water supply production while limiting adverse impacts to other users of the aquifer;
· Design and Construction of New Pumping and Conveyance Facilities - Integrating the new production sources into existing water treatment and distribution systems through about one mile of pipeline through and beneath a heavily developed active industrial facility; and
· Design of New Water Conveyance and Treatment System - Piping and industrial process water pretreatment systems to support access to several MGD of public water through an extension of public water service to the facility.

Development of Large Diameter High Yield Bedrock Product Well
Manufacturing Facility - New York
|
 SHA completed design, construction observation, logging, development, and performance testing of a large diameter bedrock well intended to supplement industrial process water needs for a manufacturing facility. Challenging geologic conditions including unstable weathered limestone and dolomite bedrock conditions at depth necessitated design of well screen and gravel pack to maintain structural integrity of the well under potential stresses associated with rock collapse and well hydraulics. The 10-inch diameter well was constructed after advancing a borehole over 400 feet through alternating zones of hard rock, highly fractured rock and soft, highly weathered rock. The Barber dual-rotary drilling method was used to advance the borehole and install steel casing telescoped from 24, to 18, to 14 inches in diameter during borehole advancement. The well was installed by retracting the steel casings to expose an engineered stainless steel well screen and gravel pack. The forces associated with the weight of the casing and friction on the borehole walls required use of a vibratory sheet pile hammer and a 40-ton crane to retract the casing. The work was made more challenging by its location in the middle of an active industrial facility with vibration sensitive manufacturing equipment. Drilling the large diameter borehole took nearly two months to complete.

Design of Water Distribution and Treatment Systems
Industrial Site
|
 SHA developed conceptual design and preliminary design estimates of construction cost for 1.2 miles of water supply force main, emergency storage capacity, and dechlorination pretreatment facilities associated with provision of public water line for potable and high purity process water use at a 640-acre industrial facility.

Irrigation Water Supply Development
Northern New England
|
 SHA completed feasibility assessment, siting, construction, and permitting assistance associated with irrigation water supply development to support improvements to an athletic field complex serving a regional Middle and High School Complex. We coordinated construction, and performance testing of three-gravel-packed wells targeting an unconfined sand and gravel aquifer also used as a public water supply.

New Source Permitting, Engineering and Construction
Water Supply Augmentation - Mid-Atlantic States
|
 SHA completed permitting of a drilled bedrock water supply well capable of producing nearly 90,000 gpd of water for both potable and process use at an industrial facility. This project included review and analysis of data from a 60-day pumping test and analytical assessment of leaky confined aquifer conditions and potential impacts on an adjacent wetland. The project also included design, permitting, and construction management of the associated public water supply systems including the pump instrumentation and control building, and a 3000-foot force main.

Water Supply System Design and Implementation
Corporate Recreation Center - Southeastern New York
|
 SHA was retained to design a drinking water treatment system to remove MTBE contamination from an on-site water supply well. The design included a 1,000-gallon holding tank, two-stage particulate filtration, filtration through carbon filters specifically engineered for adsorption of MTBE, and disinfection using ultraviolet light. The system was designed to meet varying demand requirements using a variable frequency drive with the water distribution pump. The water supply has been brought back on-line.
