Proposed Groundwater Management Goals and Strategies

The Portage County Planning and Zoning Department with assistance of the Portage County Groundwater Citizens Advisory Committee (PCGCAC) is in the process of updating the Portage County Groundwater Management Plan. The PCGCAC has suggested the following groundwater goals for:  

bulletNitrate
bulletPesticides
bulletQuantity

To achieve these goals, the PCGCAC has identified a list of strategies.

 

The PCGCAC wants your input.  What do you think?

Nitrate Goals

  1. In areas where groundwater nitrate is:
    1. Below the enforcement standard, nitrate concentrations should be maintained or lowered.
    2. At or over the enforcement standard, nitrate concentrations should be reduced to below the enforcement standard.
  1. In areas where nitrate concentrations are below the enforcement standard but cause negative environmental impacts, measures should be taken to reduce nitrate levels.

Pesticide Goals

  1. Determine what pesticides are being used and where.  Target the above areas and sample wells for detection of these pesticides.
  1. For pesticides with established groundwater standards,
    1. In areas where pesticide concentrations in groundwater are below the Preventative Action Level (PAL), pesticide concentrations should be maintained below the PAL.
    2. In areas where pesticide concentrations in groundwater are at or over the PAL, pesticide concentrations should be lowered to below the PAL.
    3. In all cases where multiple pesticides are present below their individual enforcement standards in groundwater, the sum of all pesticide residues should not exceed the most stringent enforcement standard for any of the individual pesticides detected.
  1. For pesticides without groundwater standards,
    1. In areas where these pesticides are detected in groundwater, levels should be maintained or lowered to levels below the PAL established for similar pesticides having groundwater standards.
    2. In all cases where multiple pesticides are detected in groundwater, the sum of all pesticide residues should not exceed the most stringent enforcement standard established for similar pesticides having groundwater standards.

Quantity Goals

  1. Avoid human-influenced depletion of the County’s lakes, streams, wetlands, and groundwater reserves.
  1. Identify areas within the County, which may have groundwater shortages now or in the future.

Strategies

To achieve the above goals, the PCGCAC has identified the following Groundwater and Protection Improvement Strategies:

bullet

Develop Collaborative Partnerships: The Planning and Zoning Department (P&Z) was named the lead agency in the County for Groundwater programming under the 1988 Groundwater Management Plan.  In reality, P&Z staff have worked closely with the Environmental Health Section (EHS) on health-related groundwater issues.  EHS has obtained a grant to help develop health-related content for the Groundwater Website, contracts with DNR for sampling and inspection of noncommunity public wells, and counsels citizens with known drinking water contamination.  In addition, P&Z and EHS are currently developing the well abandonment program.  (See below).  

Further partnerships will be sought between other agencies and organizations concerned with groundwater or environmental protection. (Portage County, Golden Sands RC & D, UW Extension, etc.)  

bullet

Determine Recharge Rates and Water Budgets for All of the County's Aquifers:  It will be possible to properly understand land use impacts in Portage county only if the water budgets (infiltration vs. withdrawal) for each of the County's aquifers are well understood.  This understanding is necessary in order to provide adequate groundwater resources for all, consumptive and non-consumptive (environmental, recreational, etc.) uses of our groundwater.  This will be accomplished using the County Geographic Information System (GIS).

bullet

Negotiate Conservation Easements:  This strategy would allow land in well recharge areas to remain in private ownership, but the property owner would be paid to allow only groundwater friendly land use practices.  For instance, a farmer would agree to only plant crops that could be grown without the use of pesticides or fertilizers, which could leach to groundwater.  In return, the farmer would be paid an easement fee of the difference between the value of the crop produced and the value of another crop that could have been produced had  pesticides or fertilizers been used. 

bullet

Buy Land:  Land in well recharge areas could be purchased by government or land trusts and put in a land use that would not contaminate groundwater.  This is potentially much more expensive than conservation easements.  It has been done in Portage County in Stevens Point and Whiting, with the land added to the municipal park systems.

bullet

Determine Areas with High Nitrate and Pesticide Levels: This will be done on the County GIS using sampling information on currently on file and future information obtained from other sources.  Based on this information, ongoing monitoring can be prioritized to the areas with the greatest problems. 

bullet

Develop a Portage County Pesticide Reporting Database:  It is known that certain pesticides currently or historically used in Portage County leach to groundwater, especially in areas of sandy soils.  It is very expensive to analyze groundwater samples for pesticides.  It is not economically feasible, nor a wise use of sampling funds, to analyze routinely for pesticides.  Currently, licensed pesticide applicators are required to keep records of locations and application rates of restricted use pesticides.  This information is only available to DATCP if they choose to subpoena the information.  If the dates, locations of use, and application rates of each pesticide were available to Portage County staff, it would be possible to decide likely locations to sample for individual pesticides used in these areas.

bullet

Support a Statewide Pesticide Reporting Database:  Current legislation has established a limited program in DATCP to study the feasibility of a statewide pesticide reporting database.  If Portage County wants to see a statewide pesticide reporting database established, we need to be at least as active in our support as some other interests are in their opposition.  (See previous.)

bullet

Negotiate with Corporate Food Processors Regarding Pesticides and Nutrients:  Farmers who grow vegetable crops intended for sale to the corporate food processors (e.g. Del Monte, McCain, etc.) are required by contract to grow these crops under specific conditions.  Often these conditions require nutrient and pesticide applications that can result in leaching of chemicals to groundwater.  Negotiations with processors may be able to lessen these requirements resulting in decreased potential for groundwater contamination.  A substantial amount of the land in the recharge areas for the Stevens Point, Whiting and Plover municipal wells is used for vegetable production.  Most of the land used for vegetable production outside these municipal well recharge areas contains drinking water wells for hundreds of rural families. 

bullet

Court Businesses That can Utilize Groundwater Friendly Crops:  Some crops can be grown profitably with little or no impacts to groundwater.  Specifically, legumes (alfalfa and soybeans) are commonly grown in many areas for livestock feed and other uses.  Whether farmers will grow these crops locally depends on availability of a stable market.  Businesses that use these groundwater friendly crops could be brought together with the Portage County farmers who could produce them without contaminating the groundwater.  We need to identify these businesses and determine what is needed to bring them together with the farmers.  Golden Sands RC&D is currently investigating groundwater friendly crops that can be grown in central Wisconsin and likely uses for them.  The Village of Plover has established a committee to develop ways to get farmers in its municipal well recharge area to grow groundwater friendly crops to reduce the cost of treating its drinking water in the future.

bullet

Encourage Organic and Sustainable Agriculture:  It has been demonstrated that organic farming, which eliminates the use of pesticides, has lower groundwater impacts than current mainstream agricultural practices.  While the knowledge of organic farming practices is available, we need to actively promote the use of these techniques as a means to protect and improve groundwater.  This will involve UW-Extension staff.  Sustainable agriculture means growing crops and livestock profitably without deterioration of the environment.

bullet

Establish a Well Abandonment Ordinance in Portage County:  Unused wells are a great threat for contamination of drinking water since they provide a direct route to the groundwater for any pollutants on or near the ground surface.  Currently, DNR administers the well abandonment program.  It does not have enough staff to follow up on proper abandonment of unused wells, and has offered to allow counties to administer this program as delegates of the State.  Portage County proposes to pass an ordinance vesting authority for this program in the Planning and Zoning Department, and Health and Human Services-Environmental Health Section.  Ray Schmidt and Mike Carder are developing the Ordinance, which will be submitted to DNR and to the County Board for approval and adoption.

bullet

Education and Ongoing Public Education:  A collection of items comprises this strategy.  The groundwater website, a collection of publications available in the public libraries, presentations to community groups and elected officials, development of curriculum and presentations for the area schools, and submission of articles to local media will serve to keep groundwater issues in the public eye and to allow citizens of all ages to gain enough groundwater knowledge to make educated decisions and to be involved in the political process.

bullet

Educate Rural and Urban Homeowners Concerning the Impacts on Groundwater of Septic Systems, and Lawn and Garden Fertilizers and Pesticides.

bullet

Educate Operators of Businesses and Institutions Regarding Groundwater Impacts from Landscape Practices, and Chemical Storage and Use.

bullet

Continue Current County Programs Which Affect or Improve Groundwater:  Many of the current County groundwater-related programs were established based on the 1988 Groundwater Management Plan.  These existing programs have been reviewed and determined to be necessary for future groundwater protection efforts.
