Groundwater modeling for wellhead-protection-plan amendment

About this project

client
City of Little Falls
location
Minnesota
cost
$55,000 (Barr's fees)
completion date
2019

The city of Little Falls’ wellfield is very close to the Mississippi River, and a significant portion of the water pumped by the city’s wells comes from the river. This connection to the river requires that the city's wellhead protection plan include management actions not normally included in such a document.

Barr developed a new groundwater model for the area and helped the city obtain a Minnesota Department of Health grant to cover part of the model-development cost. The new model was used to estimate the percentage of water pumped by the city’s wells that comes from the river and to delineate the wellhead protection area.
