CASE STUDIES

Wellhead Protection Plans and Annual Contamination Source Inventory

WELLHEAD PROTECTION PLANS AND ANNUAL CONTAMINATION SOURCE INVENTORY

Wellhead protection means protecting the area surrounding public drinking supply wells, and in turn, protecting drinking water supplies.

Water Level Survey

WATER LEVEL SURVEY

Mapping water levels in the shallow aquifer has helped us identify where water of poorer quality is bypassing the protective clay layer that overlies our primary drinking water aquifer.

Storm Water Digitization

STORM WATER DIGITIZATION

The City of Memphis’ storm water infrastructure was digitized from over 100,000 scanned engineering drawings that were first geo-located by CAESER in one of our largest data migration efforts.

Fayette County, Tennessee: Recharge Research

FAYETTE COUNTY, TENNESSEE: RECHARGE RESEARCH

CAESER has been conducting water recharge research at the Pinecrest Conference and Retreat Center in Fayette County for the past 15 years.

West Tennessee River Basin Authority: Recharge Research

WEST TENNESSEE RIVER BASIN AUTHORITY: RECHARGE RESEARCH

CAESER is assisting the West Tennessee River Basin Authority in assessing the impact of stream restoration projects in West Tennessee. The goal is to determine the ecological benefits of stream restoration and the heightened potential for groundwater recharge through storm water retention.

U.S. Department of Agriculture (USDA): Tennessee water availability for agriculture

U.S. DEPARTMENT OF AGRICULTURE (USDA): TENNESSEE WATER AVAILABILITY FOR AGRICULTURE

CAESER is partnering on a USDA grant with the University of Tennessee at Knoxville, University of Tennessee at Martin, Austin Peay State University and Middle Tennessee State University to focus on the long-term availability of water for agricultural production with projections to 2050.

Nambija Gold Mine - Ecuador

NAMBIJA GOLD MINE - ECUADOR

Recognizing the grave health implications of using mercury, the Ecuadorian government is looking to convert the Nambija mine into an open-pit mine that would eliminate the use of mercury and increase gold production yield by 200%.

Shelby County Landfill Groundwater Sampling

SHELBY COUNTY LANDFILL GROUNDWATER SAMPLING

A major threat to the Memphis aquifer is contamination. Though the Memphis aquifer is protected mostly by a thick overlying clay unit (aquitard), there are breaches in this clay that offer connectivity to the shallow aquifer.

Visual Stream Assessment

VISUAL STREAM ASSESSMENT

CAESER developed and implemented a mobile application for Shelby County Public Works to visually inspect and collect data for 160 miles of streams.
