ANNUAL REPORT ON WELLHEAD PROTECTION PLAN
Introduction
The purpose of this agenda item is to inform the City Council about the
status of the Wellhead Protection Plan implementation.
Historv,
The State of Minnesota Department of Health (MDH) requires cities that
use groundwater for their public water supply to develop Wellhead
Protection Plans (WHPP) to help protect groundwater from contamination
of the aquifer from which their wells draw water. The contaminants from
which cities must protect their groundwater sources include; household
chemicals, watershed practices, industrial contaminate sources, septic
systems, and others.
Current Circumstances
The City of Prior Lake completed its WHPP in 2007 and is currently in its
third year of implementation. The plan requires an annual report and
periodic evaluations. The MDH evaluated implementation of the Prior Lake
WHPP for the first time this spring.
The Prior Lake WHPP includes specific action items required to be
performed by the City during the life of the plan. Specific categories
include: well management, potential contaminate source properties, other
potential contaminate sources, general public education, and data
collection.
The following is a summary of implementation efforts made during the
2009-2010 reporting period, including an explanation of the proposed
effect:
1. Connection of Industrial Park orooerties to Citv sewer and water and
abandonment of existina seotic svstems and wells. The Pavek Property
has been connected and the Integra Property has received a permit for
connection. This eliminates two active industrial property septic
systems and wells from the City's Wellhead Protection Area.
2. Installation of Wellhead sianaae. Signs have been installed in both the
City's eastern and western Drinking Water Supply Management Areas.
These signs alert residents and business owners that they need to be
careful about how they manage household and commercial hazardous
waste as their properties are located in this critical zone.

RECOMMENDED
MOTION:
Reviewed by:
3. Drinkina Water Consumer Confidence Reoort. Inform public of test
results and procedures used to protect water supply.
4. Advertise household hazardous waste collection and disoosal. By
encouraging proper disposal of chemicals, less pollution to surface and
groundwater occurs.
5. Contaminate source database. data collection. An up to date database
of contaminates in the wellhead area helps the City target its
educational efforts.
6. Emeraencv reSDonse coordination. City Emergency response staff met
with Engineering Department staff to further wellhead protection
awareness and coordination.
In addition to all ongoing wellhead protection activities, the following areas
will be a focus of WHPP implementation in the 2010-2011 reporting period:
1. Installation of monitoring wells in the Industrial Park and Cardinal Ridge
Park to monitor both potential chemical contaminants and storm water
interactions with the City's eastern wellhead.
2. Promote proper sealing of wells in the city and townships by posting
information on website and newsletters.
3. Develop and overlay wellhead protection district to restrict activities and
uses potentially harmful to the City's water supply.
Staff will be evaluating the best means of providing a more robust wellhead
protection program in 2011. Contamination of the City's water supply
would substantially impact the health, safety and welfare of the residents.
Currently the City is unable to provide dedicated staff hours to this effort in-
house. Elimination of the Civil Engineer Position in 2008 and the Public
Works Coordinator Position in 2010 have left this important responsibility
un-staffed. The City has attempted to utilize the Water Resource Engineer
position for this activity. However based on workload and available hours,
there is not the time available to adequately complete this task without
reducing other water quality priorities. As part of the 2011 Budget Staff will
provide options for the City Council considering both in-house and external
resources to better manage Wellhead Protection.
In order to accomplish the above Wellhead Protection tasks the 2010
Budget has identified $55,000 for construction of monitoring wells and
another $7,500 for consultant assistance for contaminate source data
collection and database set up.
The City Council should accept this report and provide any direction with
regards to wellhead protection.
None required.
