Water Supply

ARM understands that an ample supply of high quality water is critical to the continued sustenance, growth, and development of our communities. Our multi-disciplinary team of hydrogeologists, engineers, and geophysicists has performed an array of water supply, protection, and management services for projects of all sizes. We have experience working for municipalities, private water companies, oil & gas companies, resort/residential clients, schools, land developers, watershed organizations, and river basin commissions. The ARM team is accustomed to providing turnkey services for numerous types of surface and groundwater related projects.

Groundwater Development

ARM’s hydrogeologists have been identifying, evaluating and developing water supplies for over 25 years. We have an intimate understanding of the geology and hydrology that directly influence the storage and movement of water, and we have developed relationships with the water commissions and regulatory agencies that oversee the use of our water resources. ARM’s scientists and engineers commonly provide the following services to assist in the development of public or private water supplies:

  • Identification of water supply sources
  • Geophysical analysis
  • Fracture trace analysis
  • New well siting and/or installation, testing, and permitting
  • Aquifer testing ( slug tests, packer tests, pumping tests)
  • Wellfield monitoring and management
  • Permitting of water supplies, consumptive uses and withdrawals
  • Well rehabilitation
  • Stream intake design and construction
  • Pond design and construction
  • Infiltration gallery design
  • Spring head design

Source Water Protection

Water resource protection involves the protection of both groundwater and surface water resources. ARM’s professionals understand the intricate relationships between surface water and groundwater flow systems, and can develop plans that range from relatively small well-head protection plans for one supply well, to comprehensive source water protection plans for an entire watershed. To support the source water protection goals of our industrial, commercial, municipal and other clients, ARM provides the following services:

  • In-depth hydrogeologic studies
  • Preparation of source water protection plans (SWPP)
  • Completion of SWPP and other grant applications
  • Assistance with public meetings and education
  • Assistance with developing protective zoning ordinances
  • GUDI (Groundwater Under Direct Influence Of Surface Water) evaluation and corrective actions
  • Assistance in establishing watershed and other conservation organizations

Hydrologic Studies

ARM professionals have completed hydrologic studies for hundreds of different sites, project objectives, and clients. These studies have focused on both water quantity and quality, and have ranged from general inventories of available water resources, to the collection of site-specific data and detailed groundwater modeling. The wide array of studies we have performed include:

  • Basin-wide water resource inventories
  • Aquifer characterization
  • Water quality and quantity determinations
  • Aquifer recharge rate evaluations
  • Integrated groundwater and surface water modeling

Well Siting Experience

ARM hydrogeologists are utilizing state-of-the-art geophysical technologies in concert with geologic studies to site successful wells for businesses, industries, municipalities and private landowners. In many cases, highly productive wells have been completed in areas where previous efforts produced low yielding wells or dry boreholes.

ARM has worked in areas with extremely complex bedrock geology, in remote locations, and within the confines of heavily populated municipalities. In addition, ARM is experienced at working with multiple local, state, and federal regulatory agencies.

ARM has been successful by understanding the various tools available to evaluate site specific geology and hydrogeology. Intrinsic in using these tools is the ability to interpret the data received from field investigation techniques such as geophysical surveys.

The diagram below illustrates the use of an electrical resistivity (ER) survey to site a 500-foot deep groundwater supply well. Using ER, the well was drilled into bedrock at the intersection of a thrust fault and a fracture zone. The well represented in this diagram produces several hundred gallons of water per minute (gpm) and supplies a nearby residential community. It is one of the highest yielding wells in the area.
