Abandoned Wells 4 & 5, Sealing Requirements UpdateROSEM0UNTEXECUTIVE SUMMARY CITY COUNCIL Utility Commission Meeting: March 11, 2013 AGENDA ITEM: Abandoned Wells 4 & 5, Sealing AGENDA SECTION: Requirements Update New Business PREPARED BY: Andrew J. Brotzler, PE, Director of AGENDA NO. r Public Works /City Engineer + ATTACHMENTS: Memorandum, E -mail APPROVED BY: RECOMMENDED ACTION: Discussion BACKGROUND The City has been notified by Dakota County that two former wells that were abandoned do not have well sealing records on file with the Minnesota Department of Health or Dakota County. Since receiving this e-mail, staff has researched city files and was not able to locate any documentation that the wells had been sealed. For older wells that have been abandoned by communities, this unfortunately is not uncommon. Attached for Commission information and discussion is a memorandum from WSB & Associates, Inc. outlining the known facts of the situation along with past experience with a similar situation in another metro area community. SUMMARY At this time, staff would like to discuss this with the Commission. As grant funding may be available in the future and there is not yet a defined timeline for addressing this matter, this is an update for the Commission and it is anticipated that future action will be requested.

The Well 4 log has no additional data regarding its status. It is not currently sealed to well code. Well 5 is shown as "abandoned ". The Well 5 log indicates that the well was sealed in 1997 by Alberg Well. I contacted Alberg and they did not work on this well. Therefore the MDH Well log for Well 5 is incorrect because it is not currently sealed to well code. Well 6 as "sealed" but with an invalid sealing record. The Well 6 log indicates that the well was sealed in 1997 by Alberg Well. I contacted Alberg and they did seal Well 6 to code in 1997, sealing number H000103261, and is the only well they have worked on in Rosemount. The Well 6 sealing project was managed by Bonestroo. Next Steps Wells 1, 2, and 3 are sealed to code with valid supporting documentation. No further action needs to be taken regarding these wells. Well 6 is sealed to code, and with the valid sealing record number no further action needs to be taken regarding this well. In order to have Wells 4 and 5 officially sealed: • They will need to be uncovered and inspected by the MDH • Any records that may exist regarding how these wells were sealed • Without useful records, they will need to be cleaned out to their full depth and then sealed to code. Minneapolis ■ St. Cloud Equal Opportunity Employer C: \Uwn\ajbWppDataU"W Mic ft\Windows\Tempomny Inte -1 Files \Conte L0mlookaTQJU01\MEM0- a bmtdu -030113- we11- =ling.dm Andy Brotzler March 6, 2013 Page 2 To the best of our knowledge, there is not a time limit to completing the sealing of these wells. In order for Rosemount to be required to locate and properly seal Wells 4 and 5, the MDH Sanitary Survey would identify the wells as a sanitary hazard to the water source. Until the MDH identifies Wells 4 and 5 as sanitary hazards, no action by Rosemount is required. Cost We have recent experience with an old municipal well that wasn't sealed to code. Mahtomedi Well 1 required sealing in 2011 in order to construct a new wellhouse for Well 4, which was adjacent to the "capped" and buried Well 1. Total cost for sealing Well 1, including both Thein Well and WSB, was $46,350.60. The project included multiple site visits, video inspections and rejections by the MDH inspector, so it represents a non - best -case scenario. As this well was similar in construction and depth to Rosemount Wells 4 and 5, the sealing cost for Mahtomedi Well 1 is useful for budgeting the cost for sealing Rosemount Wells 4 and 5. Budgeting $50,000 for each well, or a total of $100,000, would represent a conservative estimate for completing the project. Matching funds of up to $10,000 can be applied through the MDH competitive grant program to assist with funding the locating and sealing of the wells. The grant is currently accepting applications until the end of March 2013, with a project completion date of June 30, 2014. In 2014 and 2015, funds for an Unused Municipal Well Sealing Grant program are scheduled to be allocated. The details of this program have not been released yet. If sealing the wells is not required within any time limit, waiting for this program may be an option that Rosemount should consider. Option for Monitoring Well Use If these wells are located and are found to be in good condition, it may be possible to use one or both as the monitoring well required in the DNR Water Appropriations Permit as they are located in the area specified by the DNR. Once the wells are located and inspected, this option can be explored further.

Kolstad, P.E. System Contact: Bob Goebel Surveyor Signature: The findings below identify sanitary risks that may impact water quality, inform the water supply owner of applicable responsibilities, and /or provide guidance related to water system operation and maintenance. Water Source It is understood that Well No. 1 (unique # 208507) located directly east of Well No. 4 may have not been properly sealed. The city should determine the sealed status of the well as soon as possible. If no well sealing record is found, the well may need to be drilled out and resealed. Pumps /Pump Facilities and Controls No deficiencies or recommendations reported. Treatment The polyphosphate and fluoride tank vents at Well No. 5 must be separated. The break box on the fluoride feed must be vented to the outside of the building and equipped with a non - corrodible insect screen. Water Storage No deficiencies or recommendations reported. Distribution A free chlorine residual of at least 0.2 to 0.5 milligrams per liter should be maintained on all points of the distribution system. The distribution system is flushed twice a year. Monitoring /Reporting Data Verification The following records shall be maintained by the water supply system (where applicable): a. Coliform bacteria results - 5 years b. Chlorine residual results - 5 years c. Chemical results - 10 years d. Sanitary survey reports - 10 years e. All lead and copper materials - 12 years f. Consumer confidence reports - 3 years g. Turbidity results - 3 years h. Public notices - 3 years i. Fluoride quarterly results and monthly reports - 1 year Water System Management /Operation A daily check of critical system components should be conducted to enhance security and ensure that an unauthorized entry has not taken place. Emergency power should be available to operate the system in the case of a major power outage.

Operator Compliance with State Requirements The opportunity for additional training in water supply work should be made available to the operator(s). Attendance at the annual waterworks operators seminar, held in the area, is a valuable experience for anyone engaged in this field.

As promised, here is the email with more information regarding the Minnesota Department of Health (MDH) grant that is available to municipalities to seal old unused municipal wells. I am in the process of notifying all the municipalities in the county that have unsealed municipal wells of this grant opportunity . Attached is an inventory the MDH completed of the status of the City of Rosemount's municipal wells. It looks like there may not be Well and Boring Sealing records for several of the wells. Since 1989, unused wells have been required to be sealed by a licensed well contractor. After the work is completed the contractor provides the city, the county and the MDH a copy of the Well and Boring Sealing Record. It is my understanding that all the wells in the attached MDH inventory that are not in use must be sealed. You can find all the info regarding the grant at htto: / /www.health. state. mn. us /divs /eh/ wells /sealine /r)wsealineerant.html Let me know if you would like any assistance.
