Virginia Household Water Quality Program - Prince William Drinking Water Clinic

What's in Your Well Water?

It's that time of year again!

From VCE's website:

"Public water supplies are tested daily for contaminants but most private water supplies, like wells, are rarely tested. Well owners are encouraged test their water regularly to detect and correct problems early. The Virginia Household Water Quality Program (VHWQP) tests water samples for iron, manganese, nitrate, lead, arsenic, fluoride, sulfate, pH, total dissolved solids, hardness, sodium, copper, total coliform bacteria and E.coli bacteria. All for the low cost of $65.

The Prince William Drinking Water Clinic has 4 parts:

Virginia Farm Voluntary Agricultural Best Management Practices Inventory

Calling all Prince William County farmers! This survey is very important, particularly for farmers who have not participated in our cost-share assistance program!  (Farmers who have participated in the cost-share program are still encouraged to take the survey.)

From VASWCD's website:

"Virginia is embarking on a survey to help us learn more about voluntary conservation practices on Virginia farms in the Chesapeake Bay watershed…like yours!  The information you provide in response to the survey will help Virginia tell the story of what farmers are doing to conserve soil and improve water quality. This is incredibly important information that can help agriculture achieve its water quality goals for the Watershed Implementation Plan for the Chesapeake Bay."

Deadline to take the survey is March 12, 2021.

To access the survey, click here. The survey should take around 20 minutes to complete

For more information on the survey, click here.

Virginia Agriculture Cost Share (VACS)

Cost Share funding is available from the District! These funds provide financial assistance for agricultural landowners and operators to implement best management practices on their properties in order to improve soil and water quality. If you have a natural resources concern on your farm, now is the time to talk with district staff about developing a plan to address these concerns! We can provide cost-share funding for practices to address:

  • soil erosion on crop and pasture land

  • exclude livestock from waterways

  • implement nutrient management plans

  • adopt new precision nutrient application technology

  • establish tree plantings or vegetated buffers along streams

  • plant cover crops

  • construct manure storage facilities (more options available)

  • construct feed lots/sacrifice areas (New!)

In order to qualify for cost-share, your farm must meet the following:

  • Property has/had a water quality concern (e.g. livestock has/had access to a waterway, no manure storage system, no cover crops when main crops aren’t growing)

  • Property must have at least 5 consecutive acres

  • Property has been in agriculture production for the past 5 years

  • Property has produced at least $1,000 worth of agriculture products/year (agriculture products include crops, hay, and livestock, such as cattle, equine, sheep, goats, llamas, alpacas, etc. Horses solely for personal use are not considered as agriculture products.)

  • Property is located in Prince William County (if your farm outside of Prince William, contact your local soil and water conservation district; to find your district, click here.)

If you feel you have a need to implement these practices on your farm, or have any questions about the cost-share program, please contact us:

Nutrient Management: An Important Message for Producers

The 2025 Chesapeake Bay cleanup goals are here, and we need every farmer's help! We need documentation of implementation of every nutrient management plan in Prince William County. Here's what you can do to help:

  • Work with your nutrient management planner to develop a plan that can be implemented easily

  • Keep application and yield records

  • Put in place a record-keeping system so you can justify application and yield data.This must include required elements such as dates, field locations, loads, bales, bushels, gallons of manure, tons of litter, etc.

  • Share this record-keeping system with your planner.

  • Update your plan as changes occur on the farm.

  • Be prepared at the end of the growing season to evaluate how well you were able to follow your plan.


If you have questions, please contact your nutrient management planner:

(571) 379-7514
