ABSTRACT

Wrangell Island is in southeast Alaska, about 200 kilometers southeast of Juneau. The Federal Aviation Administration has ainvay support facilities on WrangeI1 Island near the City of WrangelI. They wish to consider current environmental and hydrogeologic conditions when evaluating options for compliance with environmental regulations at these facilities. WrangeH Island lies in the maritime climate zone and has mild winters and cool summers. Local vegetation consists of coastal western hemlock-Sitka spruce forest. The bedrock on WsangelF Island consists of sedimentary and intrusive rocks of Cretaceous age. The principal suficial materials are beach, alluvial, and glacial deposits. The Stikjne River, Mill Creek, and the Wrangell City Reservoirs are the principal fresh surface-water bodies near the Federal Aviation Administration facility. Limited amounts of ground water may be found in unconsolidated deposits or bedrock. Most residents on the island obtain their drinking water from surface-water sources. Ground water may be an alternative drinking-water source; however, the quantity and quality of these resources is poorly documented.

INTRODUCTION

The Federal Aviation Administration (FAA) owns and operates airway support and navigational facilities throughout Alaska. Fuels and potentially hazardous materials such as solvents, polychlorinated biphenyls, and pesticides may have been used and (or) disposed of. To determine if environmentally hazardous materials have been spilled or disposed at the sites, the FAA is conducting environmental studies mandated by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Resource Conservation and Recovery Act (RCRA). To complete these more comprehensive studies. the FAA quires hydrogeologic information of areas surrounding the sites. This report, the product of compilation, review, and szlmmary of existing hydrologic and geologic data by the U.S. Geological Sumy, in cooperation with he FAA, provides such informadion for the FAA facility and nearby areas at Wrangell, Alaska.

BACKGROUND

Location

The city of WrangeH is located on Wrangell Island in southeast Alaska at approximate lat 56"28' N., long 13Z022"W (fig. 1). It is abut 200 km southeast of Juneau and about 1050 km southeast of Anchorage. The island lies in the foothills of the Coast Range and has a topography Wgure 1. Location of Wmngell, Alaska and the Federal Aviation Adminishation facility. characterized by blocks of high mountains 5-50 km wide, separated by valleys and straits 0.8-16 km wide (Wahrhaftig, 1965). The Eastern Passage lies north and east of Wrangell Island and Zimovia Strait is due west (fig. 1). The WmgeII FAA facilities are concentrated at the airport near the northern tip of the island (fig. 1).

History and Socioeconomics

The Tlingit and the Haida Indians occupied this par^ of Alaska before the htnon-Native contact in 1834 (Sehgg, 1976). Each Indian clan was based on maternal descent and relied on subsistence activities such as hunting and fishing for survival. The first non-Native settlement was a stockade built by occupying Russians in 1834, The Russians called the stockade Red Dioniciya meaning Redoubt Saint Dionysius (Orth, 1967). h 1839, the British leased part of southeast Alaska from the Russians and changed ~e name to Fat Stikine. The United States purchased Alaska from Russia in 1867 and the name was changed to Fort Wrangell (Orth, 1967). The City of Wrangell became an important supply center for fur traders and gold miners during the time of the Stikine gold rush (Orth, 1967). In 1890, the population of Wrangell was 316; in 1938, it was 1,000; in 1950, it was 1,162; and by 1990, the population had grown to 2,479 (Orth, 1967; U.S. Bureau of Census, 1991). According to the E 990 W.S. Census, about 20 percent of the people are American Indian, Eskimo, or Aleut, 79 percent are Caucasian, and 1 percent are African-American, AsianlPacific Islander, adof other ethnic origin. Residents of Wmgell have suppotted themselves on subsistence activities such as fishing and hunting, but today more people rely on a cash economy. Employment is mostly in private sector, natural-resource based activities such as commercial fishing, logging, lumber and pulp, towism, retail trade, and services. According to the 1990 U.S. Census, Wrmgell has a potential work force of 1,803 people: 725 work for private organizations, 290 for the Federal, State, or local government, 165 ate self-employed, 9 are unpaid family workers, 117 are unemployed, and 497 are not in the labor force. The FAA activities on Wmgell Island began in 1969. Currently, the FAA facilities at WmgeU, include a visual appmch slope indicator, runway end identification lights, an automated weather observation station, a telecommunication cabb site, and n display site. A detailed account of FAA facilities near Wrangell and a listing of suspected sources of contamination around these facilities can be found in an environmental compliance investigation report by Ecology and Environment, hc., (1993).

PHYSICAL SEITIING

Climate

Wrangell has a maritime climate characterized by small temperature variations, high humidity, and abundant precipitation. It has wet, coo1 summers and relatively mild winters (Hartman and Johnson, 1984). The mean annvd temperature is 6.3"C.Tempemtues range from a July mean maximum of 18.2"C to a Janwy mean minimum of -4.3'C (Leslie, 1989). Mean annual precipitation is abovt 2,070 mm and about 1,580 mm of snow falls annually (Leslie, 1989). Mean monthly and annual temperature, precipitation, and snowfall are summarized in table 1.

Vegetation

Vegetation on Wmgell Island consists of coastal western hemlock-SitEta spruce forest, The forest is characterized by an overstory of Si tka spruce, western hemlock, and Alaska yellow cedar with an understory of blueberry, five-leaf bramble, single delight, skunk cabbage, and mosses (Alaska Department of Community and Regional Affairs, 1984; Viereck and Little, 1972). Expanses of subtidal wetlands exist in nwnerous places on Wrangell Island and surmund the FAA facilities. Wetland vegetation consists of silverweed, hair grass, yarrow, buttercup, and a variety of ages. Alpine vegetation, starting at about 600 rn above sea level, comprises mountain hemlock, deer cabbage, heather, lichen, berries, and willow.

GEOLOGY

The geology of WrangeIl Island has been described by Berg (1980), Karl and Kwh (1985, 1990), Hunt and Brew (1986), Brew and others (1989), and Berg and Gehrels (1992). The bedrock on Wrangell Island consists of sedirnenw and intrusive rocks of Cretaceous age, The sedimentary rocks consist of marine pywacke, mudstone, and minor amounts of limestone (Berg and Gehrels, 1992). Other rock types on the island include andesitic to basaltic volcanic rocks. Intrusive rocks near the city of WrangeSE include small plutons and batholiths of granodiorite, tonalite, and subordinate quartz diorite that ate part of the Coast Range (Berg and Gehrels, 1992). Bedrock is exposed at low tide on northern Wrangell IsIand. Further inland, where covered by surficial deposits, bedrock may be more than 10 rn below land surface (Waller and Tolen, 1962).

4 Qmkwof Envlronmtd and Hydrogeologk CbndlWm at. Wranw, Almh The principal surEicial materials found on Wmgell Island are beach, alluvial, and glacial deposits. 2Lpicd beach deposits consist of Iayers of gravel and sand which were reworked from glacial deposits by wave action and tidal currents. Alluvial deposits in the same area include stratified silt, sand, and gravel. These deposits are between 1.5 and 5.0 m thick and are found along the flood plains of large streams and rivers. Glacial deposits consist of unconsolidated silt, sand, gravel, and boulders. Waller and Tolen (1962) describe the lithology of sediments from a well drilIed to a depth of 30 m in the city of Wrangell, as muskeg to a depth of about I .O m; hard clay and boulders to a depth of about 8.5 m; and hard black slate (bedrock) 30 rn below land surface (Appendix I). The soils that develop on the well-drained surficial materials are characterized by an organic-rich layer 5-12 cm thick, and dark, acidic sub-layers (Neger and others, 1979). Wrangell lsland is free of permafrost (Fenians, 1965). Wrangell Island lies within the circum-Pacific seismic belt that rims the north Pacific &em. The area is traversed by the Chatham Strait Fault, the Fairweather Fault, and numerous smaller faults. In recent years, several earthquakes with Richter scale magnitudes greater than 7 have been recorded along these fault systems (Brewer and others, 1977; Stephens and others, 1986).

HYDROLOGY

Surface Water

The Stikine River, Mill Creek, and the Wrangell City Reservoirs are the principal fresh surface-water bodies near the FAA facility (fig. 1). The Szikine River is less than 10 km north of the FAA facility and flows from northeast to southwest. MiH Creek is about 5 km southeast of the FAA facility, flows from southwest 20 northeast, and empties into heEastern Passage. The WrangeIl City Reservoirs are due south of the city of WrangelI and ate used as drinking-water sources. A nwtherjy topographic gradient of about 20 mlkm directs runoff from the FAA facility towards the coast. Ddly mean discharge of the Stikine River was reported from 1976 to 1993 at stremfl ow gaging-station 15024800, hated about 30 h northeast of Wrangell Island. During open-water months from May to September, mean flow is about 3,300 m3/s and during the winter from December to April, mean Row is about 370 m3/s ((table 2: U.S. Geological Survey, 1994). The mean annual discharge of the river is about 1,630 m3/s. The Stikine River drains an area of about 52,000 km2 upstream from the gaging station (U.S. Geological Survey, 1994). Average annual runoff in the Stikine River drainage area is about 0.03 (m3/s)kmz (U.S. Geological Survey, 1994). tsble 2 Mean monthly flow at streamflow gagkngstation 15024800, the Stikine Aiver near Wrangell, Alaska, 1876-93 water years [Values in cubic meters per aecondj

HYDROLOGY 5 Mi11 Creek is a small stream originating in the upland area just south of the FAA facility (fig. 1). This stream drains an area of about 0.2 km2 upstream from streadlow gaging-station 15087000, where a partial-record of discharge for the period 1964-66 was collected. Maximum mean monthly discharge during periods of heavy rainfall in September and October is abut 0.1 m3/s and minimum mean monthly discharge during June and July is about 0.004 m3/s (U.S. Geological Swey, 1967). On Septemtxr 3, 1966 rainfall runoff caused a maximum creek discharge of 4 rn3/s. Mean annual runoff for Mil Creek near Wrangell is about 0.1 (m3/s)lkmz. The diurnal tide rang-the difference in height between mean high water and mean low water during a single day-near the city of Wrangell averages 4.8 m (Brower and others, 1977). The maximum daily tide predicted to occur at Wrangell, Alaska is 5.9 m above sea level. The minimum predicted daily tide is -1.2 m below sea level @rower and others, 1977).

Floods

The city of WmgeU has a low flood hazard rating and has no history of significant waterfront flooding (Federal Emergency Management Agency, 198 1; U.S . Army Cqsof Engineers, 1993). Although there is a small risk of flooding by storm-surge or tsunami waves, the Thanksgiving Day Storm of 1968, consided to be the largest storm in recent times, produced no unusual flooding in Wrangell. (Federal Emergency Management Agency, I 98 1; U.S. Army Corps of Engineers, 1993). Whds at that time wele generally from the southeast and the effects from high waves and storm surges were negligible. A storm on Octokr 26, 1976, considered to be less severe than the Thanksgiving Day storm, did cause some waterfront damage near Wrangell (Federal Emergency Management Agency, 1981). The winds were predominately from the southwest, an unusual direction. These winds acting over a large area of water resulted in a combination of high tide and large waves that eroded fill and exposed sum homes to minor wave and log damage. Brower and others (1977) describe return periods for maximum wave heights for coastal areas in Alaska. A 100-year-wave more than 20-m high is estimated for coastal areas near Wrangell Island (table 3). A flood of this magnitude may affect the FAA facility which is about 10 m above sea JeveL

6 Orsrvlw ot EnMmmnsnrd and Hyrltogeologle Condltbm at; Wrangell, Alarka Riprapping of exposed land formations has provided flood protection dong Zimovia Strait and the Eastern Passage (Fedml Emergency Management Agency, 198 1). Protection for the small boat harbor is provided by a rubble mound breakwater constructed in 1926. The structure is well armo~dand shows no signs of damage (Federal Emergency Management Agency, 198 1). Over-bank flooding of stream channels in southeast Alaska usually occurs during heavy rainfall; snowmelt rarely causes flooding. Flood crests are typically of short duration, often less than one day, and are characterized by a very sharp rise and decline of flow. On September 1 1,1981 rainfall runoff caused a maximum discharge of about 8,500 m3/s at U.S. Geological Survey stream- gaging station 15024800, on the Stkine River near WrangelI, Alaska (U.S. Geological Survey, 1994). However, no flooding was reported near the city of Wrangell at this time.

Ground Water

Most communities in southeast Alaska use the abundant surface-water supplies for domestic use. As a result, ground-water data are scarce. Near Wrangell, ground water may be found within unconsolidated deposits or fractured bedrock Several wells have hen drilled near the city of Wrangekl (Appendix 1; Waller and Tblen, 1962). Well depths ranged from 15 to 73 rn below land surface and water levels were between 0.2 and 9 rn blow land surface. Well yields ranged from 0.6 to 4.7 us. Following 16 hours of bailing, a 73-rndeep well in the city of WrangeII was reported to have 54 rn of drawdown (Waller and Tolen, 1962). It is not known how Tong it took the water level: to recover. The possibility of salt-water intrusion into coastal and island aquifers increases with depth and pumping rate (Waller and Tolen, 1962). However, no significant analyses of saltwater intrusion have been conducted near Wrangell.

DRINKING WATER

Present Drinking-Water Supplies

The Wrangell City Reservoirs, two reservoirs in the upland area south of Wrngell, supply the city and the FAA facility with water f Alaska Department of Community and Regional Affairs, 1984; Ecology and Environment Inc., 1993). The water is chlorinated and stored in a 666,000 L tank. The water is distributed by pipe to residents and businesses. Avemge water use in Wrangell city is about 2,625,000 L/d (Alaska Department of Community and Regional Affairs, 1984). The capacity of the public system is about 3.7 million L/d (Alaska Department of Community and Regional Affairs, 1984). From 1958 to 1974, the U,S. Geological Survey sampled water from the Wsangell City Reservoirs (table 4; Appendix I). Major ions, dissolved metals, and other analyzed constituents were within cursent U.S. Environmental Protection Agency (USEPA) and the State of Alaska Department of Environmental Conservation (ADEC) drinking-water regulations (ADEC, 1995; USEPA, 1995). The reservoirs are about 90 m above sea level upgradient from the city and the FAA facilities and, therefore, should not be susceptible to contamination from surface spills or disposal of hazardous wastes from these sources.

Alternative Drinking-Water Sources

Drinking-water alternatives for the FAA facility and the city of Wrangell include the Stikine River, Mill Creek, and ground water. Ground water in sufficient quantity for a municipal: supply, however, has not been identif 4, Ground water is generally present at depths between 0.2 and 9 m below land surface with yields between 0.6 and 4.7 Us.Analyses of ground-water samples indicate that major ions, with the exception of iron, and water properties are within current USEPA md ADEC drinking-water reguIations (table 5; Appendix 1).

The Stikine River represents a potential source of drinking water for the Wrangell Island area. During months of low discharge, mean flow of the fiver is about 300 m3/s (table 2; U.S. Geological Survey, 1994). This is far greater than the estimated water use for the city of Wmngell. The quality of the S&e River was measured fsom 1976 to 1993 by the U.S Geological Survey. Measured concentrations of major ions, nutrients, and water properties in the Stikine River are within current USEPA and ADEC drinking-water regulations (table 6; Appendix 1; W.S. Geological Survey, 1994). Table 6. Selected water-quality data for the Stikine River near Wrangell. 1993 water year [m@, mllligrarm per liter]

Although the discharge from Mill Creek is small, it addpossibly be used to supplement the present drinking-water supply if needed. Chemical analyses of water quality in Mill Creek have not been conducted. Suspended-sediment concentrations, however, ranged from 0 to 8 rnglL (U.S. Geological Survey, 1966). The USEPA recommended guideline value for suspended sediment concentration is 5 mg/L (USEPA, 1995).

Wrangell Island is in southeast Alaska about 200 km southeast of Juneau. It lies in the &time climate zone and has relatively mild winters and cool summers. A natural-resource based economy and supplemental subsistence lifestyle make local residents dependent on a sustainable environment. Flooding by tsunami and storm-surge waves is a low-wted hazard. The city of Wrangell and the FAA facility obtain their drinking water from two reservoirs. The Stikine River, Mill Creek, and ground water represent possible alternative drinking-water sources.
