Chapter 1

Introduction The 1994 Wellhead Protection Area Study and associated groundwater flow models were used to develop this Wellhead Protection regulation.

1-1. Setting

a. Fort McCoy is located in the west central portion of Wisconsin in Monroe County, approximately 30 miles east of the Mississippi River. The installation occupies parts of six townships. The city of Tomah is located approximately ten miles southeast of Fort McCoy, and the county seat is in the city of Sparta, located about nine miles southwest of the installation.

b. Streams on Fort McCoy flow into two river basins; the La Crosse River and the Black River.

Headwaters of the La Crosse River are located in the Northeastern portion of Fort McCoy. Ranch and Clear Creeks, both located in the Northwestern portion of the installation, flow into the Black River basin.

Land east of the installation boundary, including a very small portion of the installation, is located in the Lemonweir River portion of the Wisconsin River basin. There are approximately 70 miles of streams and tributaries on the installation with approximately 50 miles recognized by the Wisconsin Department of Natural Resources (WDNR) as trout streams. Groundwater supplies 66 percent of annual stream flow in the area (Rust, 1994).

c. Unconsolidated deposits beneath the installation consist mainly of sand, with some silt and gravel.

Clay is only present at isolated locations. Thickness of the unconsolidated deposits range from 0 to 120 feet. The unconsolidated materials are underlain by Ordovician dolomite on ridge tops, and Cambrian sandstone, siltstone, and shale in the valley areas.

d. Two main aquifers are present beneath the installation: the unconsolidated alluvial aquifer, and the Cambrian sandstone aquifer. The upper portion of the Cambrian sandstone aquifer is interconnected with the unconsolidated aquifer. Depth to groundwater beneath the installation ranges from zero in the marshy areas to as much as 20 feet in the valleys, and may be greater at some locations on ridge tops. Regional groundwater flow in the upper sandstone and unconsolidated material is generally to the southwest, toward the La Crosse River, with shallow flow toward local streams and rivers.

(1) Hydraulic conductivity of the unconsolidated aquifer ranges from 4.4 x 10

-4 cm/sec to 4.5 x 10

-2 cm/sec (1.24 to 127.6 ft/day), and hydraulic conductivity of the sandstone aquifer ranges from 5.2 x 10 -4 cm/sec to 4.2 x 10 -2 cm/sec (1.47 to 119 ft/day) (Rust, 1994).

(2) Fort McCoy’s drinking water is obtained from the Cambrian Sandstone aquifer. The installation operates three water systems: North Post (cantonment area), South Post (family housing area), and the Airfield systems. The North Post and South Post systems are classified according to chapter NR 811, Wisconsin Administrative Code as “Other than Municipal, Community” water systems. The Airfield System is classified as a transient non-community system. These systems are particularly susceptible to contamination from surface activities due to the shallow water table and the high permeability of area soils. Additionally, most of the water supply wells draw water from relatively shallow depths (i.e., less than 75 feet below ground surface).

1-2. Purpose

a. The purpose of this regulation is to define the responsibilities and procedures for wellhead protection and the continued delivery of a safe potable water supply at Fort McCoy. This regulation is established to ensure the continued safety and high quality of Fort McCoy’s three water supply systems. Wisconsin Administrative Code NR 811.16(5) requires Wellhead Protection Plans for Municipal Water Systems and the Fort McCoy water systems are permitted as Municipal Water Systems. Army Regulation (AR) 200-1 requires installations to prepare groundwater protection plans to “protect groundwater sources from contamination”. This plan satisfies both requirements. This plan restricts fueling, maintenance, grey water disposal, and parking of vehicles containing pesticide, herbicide, or insecticide, within 100 feet of training

Fort McCoy Regulation 420-30, 1 June 2010 2 area wells. In addition, this regulation prohibits obtaining mixing water for pesticides, herbicides, and insecticides from wells located in the training areas, and mixing these materials within a 100-foot radius of these wells. Other than these restrictions this regulation does not address water supply wells located in the training areas that are not part of the three Fort McCoy water systems. Training area wells are used infrequently and are generally located in areas less susceptible to potential contamination due to less frequent surface activities. Additional protection of the groundwater present beneath the range areas is addressed by the requirements of the Spill Prevention Control, Countermeasures and Spill Contingency Plans (Fort McCoy Regulation 420-28).

b. Reference material utilized to prepare this regulation is outlined in appendix A. This material is available for review at the Directorate of Public Works (DPW) Environmental Division office, 2171 South th Avenue.

1-3. Definitions

a. Time of Travel (TOT): The amount of time required for groundwater to travel within the aquifer from a specific point upgradient of a water supply well to that well. This refers to horizontal groundwater migration, and does not include the travel time required for infiltration from ground surface or vertical migration through the unsaturated zone to the aquifer.

b. Fort McCoy Wellhead Protection Areas (WHPA): An area encompassing approximately the five year TOT for the groundwater supplying a particular well. Maps showing the Fort McCoy WHPA can be viewed at the DPW Environmental Division office, 2171 South 8th Avenue.

Chapter 2

Chapter 3

Prohibited Activities

3-1. Specific Prohibitions

In order to continue to protect the drinking water supplies for Fort McCoy, the following list of prohibited practices will be utilized to evaluate existing and new activities proposed for location within the WHPA.

Other activities may be prohibited within the WHPA if it is determined that they represent a significant threat to the aquifer. Mission-critical circumstances may dictate that one or more of the prohibited activities be allowed for new facilities/operations within the WHPA. Should this become necessary, sufficient protective measures (engineering design, operational practices, and/or personnel training) shall be implemented to minimize the potential for water supply contamination. The Environmental Division is responsible for review and approval of these measures. The proponent for the requested activity/new construction is responsible for costs associated with implementation of all required protective measures.

a. Any manufacturing or industrial activities, including vehicle/equipment maintenance activities.

b. Asphalt products manufacturing.

Fort McCoy Regulation 420-30, 1 June 2010 4

c. Bulk fertilizer storage and/or pesticide storage facilities.

d. Liquid motor fuel dispensing facilities/operations.

e. Hazardous and/or toxic materials or waste storage (Flammable storage cabinets are excluded from this provision).

f. Contaminated soil storage or thin-spreading activities.

g. Large-scale printing and duplicating services.

h. Recycling facilities (not including recycling pick-up points).

i. Salt storage.

j. Septage and/or sewage sludge spreading.

k. Petroleum product storage tanks.

l. Wastewater treatment or disposal facilities.

m. Landfills or waste disposal facilities (not including dumpsters and roll-off containers).

n. Target/backstop areas, impact areas, firing of large munitions and burning powder charges. This prohibition does not include firing of small caliber weapons and hunting. (Accumulation of projectile materials, along with the release or accelerant materials and metal fragments during firing of large munitions creates a real threat to groundwater quality.)

o. Grey water infiltration trenches (or similar disposal operations) within a 100-foot radius of water supply wells located in the training areas.

p. Fueling or vehicle/generator maintenance operations within a 100-foot radius of water supply wells located in the training areas.

q. Parking of any vehicle containing pesticides, herbicides, or insecticides (other than those contained in aerosol metal spray cans) for any amount of time within 100 feet of a potable water well.

r. Obtaining mix water for pesticides from wells located in the range areas or from restrooms, kitchens, or other potable water locations on the installation. Such mix water shall be obtained from a fire hydrant utilizing backflow prevention, a designated non-potable bulk water supply location, or from designated locations in building 2220.

s. Mixing of pesticides, herbicides, or insecticides within the WHPA or within a 100-foot radius of any well located within the range area.

3-2. Minimum Setback Distances

Wisconsin Administrative Code Chapter Natural Resources (NR) 811 provides minimum setback distances from water supply wells to various activities. Utilizing guidance given in NR 811 and the hydrogeologic information for the Fort McCoy WHPA, the following activities may be conducted within the

WHPA if the following set back requirements are met:

Fort McCoy Regulation 420-30, 1 June 2010 5

a. Vehicle staging/storage areas (≥ 600 feet, with weekly inspections provided by the proponent, when the proponent is present on the installation).

b. Sanitary sewer main, manhole, lift station (≥ 200 feet).

c. Septic tank or soil adsorption unit receiving less than 8,000 gals/day, a cemetery, or a storm water retention basin (≥ 400 feet).

d. Storm sewer main (≥ 50 feet).

3-3. Existing or Proposed Operations Operations located within the WHPA that violate (or that may violate) subchapter 3-1 or 3-2 of this regulation, in existence at the time this regulation is promulgated, will be allowed to continue and operators of these facilities will be educated, through the Fort McCoy Regulation 420-28 - required Spill Awareness & Hazardous Material Training, to minimize the potential for water supply contamination. In addition, current operations at these facilities will be periodically inspected and evaluated by the DPW Environmental Division. A list of the facilities that violate the requirements of this regulation, but have been allowed to continue operation can be viewed at the DPW Environmental Division. As the Environmental Division becomes aware of activities that violate or may violate this plan, they will recommend modifications/upgrades to current and new operations as appropriate, and such modifications/upgrades will be implemented (including purchase and installation of additional equipment) as funding permits to reduce risks to the Fort McCoy water supply.

Chapter 4

Best Management Practices (BMP) The following best management practices will be implemented to further protect Fort McCoy’s drinking water quality.

4-1. Storage Requirements All hazardous materials and wastes, regardless of location on the installation, shall be stored within containers/facilities that have secondary containment (i.e., flammable cabinets or spill pallets). The operators of hazardous materials and waste storage areas will inspect their areas weekly per WAC NR

615.05 and Fort McCoy Regulation 420-25, Hazardous Waste/Material Management Plan.

4-2. Inspection Requirements All personnel (military/civilian/contractor) responsible for any vehicle or equipment stored within the WHPA will inspect their parking/storage areas weekly for leaks or spills (during all times when such personnel are present at the installation). Leaks or spills shall be reported to the Fort McCoy Fire Department (608-388- 2000) immediately upon being discovered, in accordance with Fort McCoy Regulation 420-28.

Vehicles/equipment with bulk fuel dispensing tanks, regardless of location on the post, that will be in any area for 24 consecutive hours or more shall be stored/parked on secondary containment at all times.

Operators of these vehicles shall inspect and maintain such secondary containment. Accumulated precipitation within the secondary containment will be disposed of by draining the containment if there is no visible evidence of sheen or floating product. If a sheen or floating product is visible in the secondary containment, DPW Environmental Division shall be contacted at extension 2-2160 for assistance in draining the secondary containment and disposing of the liquid.

4-3. Well Abandonment The planned abandonment of water supply wells SW-5, SW-6, SW-8 and SW-18 will eliminate all of the current prohibited activities within the North Post WHPA except for the materials and activities at building 10005, which will still be located within the down-gradient portion of the WHPA for SW-9 and the Medical FOB site located on the southern boundary of the WHPA.

Fort McCoy Regulation 420-30, 1 June 2010 6

4-4. Fort McCoy Regulation 420-28 Required revisions to the Fort McCoy Regulation 420-28, Spill Prevention, Control, Countermeasure, and Spill Contingency Plans, currently administered by contract DPW Environmental Division personnel, will continue to include material related to this Wellhead Protection Plan, and the appropriate facility operators will be required to attend the annual Spill Prevention Awareness training.

4-5. Spills Within the WHPA In order to determine if any future water supply contamination may be the result of past spills, spill incidents that occur within any of the WHPA and resulting cleanup activities will be appropriately tracked.

4-6. Sampling In order to ensure that installation water supplies are not contaminated with accelerants, samples from all new potable wells will be analyzed during the first two annual monitoring events for accelerants. If accelerants are detected at levels of concern, the well will not be utilized until the concentrations of constituents of concern are below the health based levels.

Chapter 5

Contingency Plan

a. At any time data or other conditions/observations indicate that any of the Fort McCoy wells have been contaminated (with any constituent other than bacteria), those wells will immediately be disconnected from the supply/distribution system in a manner that will eliminate the potential for any contamination from that well to enter the Fort McCoy water supply. In addition, both the high level and low level reservoirs will be sampled for the parameters of concern (on a quick-turn basis) to ensure that the water within the reservoirs continues to meet regulatory drinking water standards. Should sampling results indicate that one or both of the reservoirs have been compromised; the compromised reservoir(s) will be purged and resampled.

b. The contaminated well(s) and reservoir will not be re-used until laboratory data show that the water meets the NR 140 standards.

Chapter 6

Future Updates This Regulation will be updated annually, or when changes require a more frequent revision to the plan.

Once water supply wells SW-5, SW-6, SW-8, and SW-18 are abandoned, this regulation and the associated WHPA will be updated.
