Naturally occurring arsenic can make groundwater unsafe for drinking. Before going to the expense of drilling a well and sampling the water for arsenic, it would benefit public health to be able to predict the level of arsenic in groundwater in a certain area. A special research project with the U.S. Geological Survey is designed to develop the capacity to assess local geological conditions, related groundwater chemistry and well construction factors in three counties in order to predict the levels of arsenic found in groundwater related to those variables.
This project will characterize unregulated drinking water contaminants at wells and intakes (which pump from groundwater, lakes, rivers), and to examine if they persist after standard public water system treatment.
The County Well Index (CWI) contains well and boring records wells within Minnesota; over 400,000 records. It is the principal source of well construction information and geologic interpretations of well records and also contains soil boring records, mineral exploration test hole records, and scientific/research test hole records.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
This is a project to to proactively address future threats to safe drinking water. This project will incorporate findings and recommendations from the Future of Drinking Water report to assess, prioritize, and manage drinking water risks. Through this project, a voluntary statewide plan for protecting drinking water will be developed. Additional outcomes from this project include public health policies and an action plan.
The Lake Superior Beach Monitoring and Notification Program exists to test recreational beach water and notify the public if bacteria levels become unsafe. This project will expand the Beach Program to include additional outreach efforts, sanitary surveys and testing of new technologies to improve the Beach Program. Monitoring results will be used to inform the public, find the sources of bacterial contamination and address polluted runoff from improper waste disposal.
Appropriations from the Clean Water Fund allow the Minnesota Department of Health to expand and improve the way groundwater and drinking water protection is implemented at the local level. In 2015, $300,000 was allocated to update wellhead protection areas within groundwater management areas. From 2016 onward, funding will be dedicated to the Groundwater Restoration and Protection Strategies (GRAPS) initiative which will provide groundwater and drinking water information and management strategies on a HUC 8 watershed scale.
The objective of this project is to build on previous efforts aimed at determining the public health risk due to virus contamination in Minnesota groundwater. The Minnesota Department of Health will examine the occurrence of viruses in non-disinfecting groundwater sources in Minnesota as well as evaluate the association between source water virus occurrence and community acute gastrointestinal illness.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
Improve security by purchasing and installing doors on city's well house, create and publish article on protecting source of water, potential contaminants, and wellhead program.
Drill well to clear pump for borehole geophysical survey on well 2. Purchase spill response materials to be better prepared in case of spill or train derailment.
Construct a well. Extend new overhead drop from existing power pole to pump house for 240 volt service. Extend new circuit from loadcenter to location of new pressure switch and well control box.
Continue PCSI update; Manage, identify sites with documented environmental contamination; Reminder notices to tank owners regarding leak detection and state and federal regulations; Coordinate training and information session with MPCA and the City Fire D
