CONVERSION FACTORS AND ABBREVIATIONS -

For the convenience of readers who may prefer to use- metric (International System) units rather than the inch-pound units used in this report, values may be converted by using the following factors:

Multiply inch-pound unit By To obtain metric unit

foot (ft) 0.3048 meter (m)inch (in) 25.40 millimeter (mm)mile (mi) 1.609 kilometer (km)

Chemical concentrations and water temperature are given in metric units. Chemical concentration is given in milligrams per liter (mg/L) or micrograms per liter (jug/L) . Milligrams per liter is a unit expressing the concentration of chemical constituents in solution as weight (milligrams) of solute per unit volume (liter) of water. One thousand micrograms per liter is equivalent to one milligram per liter, For concentrations less than 7,000 mg/L, the numerical value is the same as for concentrations in parts per million.

Water temperature is given in degrees Celsius (°C), which can be converted to degrees Fahrenheit (°F) by the following equation:

F = 1.8(°C) + 32

GROUND-WATER QUALITY DATA FOR THE SACO RIVER VALLEY GLACIAL AQUIFER FROM BARTLETT, NEW HAMPSHIRE TO FRYEBURG, MAINE: JULY 1984 THROUGH NOVEMBER 1985

by Carole D. Johnson, Dorothy H. Tepper, and Daniel J. Morrissey

ABSTRACT

This report presents ground-water quality data collected for a study of the Saco River valley glacial aquifer. The study area extends along the Saco River from Bartlett, New Hampshire to Fryeburg, Maine. The study was done in cooperation with the Maine Geological Survey (Department of Conservation), the New Hampshire Water Supply and Pollution Control Commission, the New Hampshire Water Resources Board, and the Town of Conway, New Hampshire. * "*' The data include 129 analyses of ground-water chemistry from 92 sites. Field determinations include pH, temperature, and specific conductance. Laboratory determinations include nutrients, common inorganic anijons and cations, selected volatile organic compounds, and detergents. "^.The chemical analyses are summarized in tables. Maps show the locations of the data-collection sites.

INTRODUCTION

The extensive, unconfined sand and gravel aquifer located along the Saco River from Bartlett, New Hampshire to Fryeburg, Maine is an important water supply for this region (U.S. Army Corps of Engineers, 1982). A quantitative investigation of this resource was initiated in 1984 by the U.S. Geological Survey, in cooperation with the Maine Geological Survey (Department of Conservation), the New Hampshire Water Supply and Pollution Control Commission, the New Hampshire Water Resources Board, and the Town of Conway, New Hampshire.

The objectives of this study are to determine the quantity and quality of water available from the aquifer, the effects of increased pumping on water levels in the aquifer, and the effects of various land-use practices on ground-water quality.

Purpose and Scope

The purpose of this report is to make water-quality data from this study available to those concerned with timely and effective water- resources management. The data presented were collected from July 1984 through November 1985. The data include 129 analyses of ground-water chemistry from 92 sites. Field determinations include pH, temperature, and specific conductance. Laboratory determinations include nutrients, common inorganic anions and cations, selected volatile organic compounds, and detergents.

Description of the Study Area

The study area is located in east-central New Hampshire and south- western Maine, along a section of the Saco River extending from Bartlett, New Hampshire to Fryeburg, Maine (fig. 1). The Saco River provides primary drainage for the area.

The Saco River valley glacial aquifer consists of unconsolidated sand and gravel. These surficial deposits have been mapped by Leavitt and Perkins (1935), Prescott (1980), and Thompson (1985).

Major land uses in the Conway area include the lodging and restaurant business, retail business, light industry, and farming. Land use in the Fryeburg area is primarily agricultural.

Acknowledoments

The authors express their appreciation to the North Conway Water Precinct, the Lower Bartlett Water Precinct, the Conway Village Fire District, and the Fryeburg Water Company for access to municipal wells. Thanks are also extended to town officials and to the many private citizens who granted permission to drill and sample observation wells.

METHODS

Installation and Development of Observation Wells

Seventy-nine wells were installed to obtain information on water quality, grain-size of the sediments, stratigraphy, depth to water table, depth to bedrock, and hydrologic data.

A hollow-stem auger drill rig was used for exploration hole drilling. In this method of drilling, fluted auger sections 5 feet in length and 6 inches in diameter are rotated in the hole. New sections are added at the drill head as the hole progresses. Samples of the sediment above the water table are brought to the surface by the rotation of the augers. Sediment samples below the water table are

A collected ahead of the drill stem with a split-spoon sampler.

The exploration holes were cased with 2-inch diameter schedule 40 PVC (polyvinyl chloride) plastic pipe. The casing has 4-foot-long screens with slot widths of 0.006, 0.010, or 0.018 inches. All casing lengths, screens, and couplings were fastened with 3/8-inch sheet metal 'screws rather than with PVC cement, which releases tetrahydrofuran. The PVC cement can raise concentrations of volatile organic compounds to above background levels. The casing and screen were emplaced inside the hollow stem auger, and the hole was allowed to collapse as the drill stem was withdrawn.

rr Immediately after the casing was emplaced, water was pumped down to aid well development. At a later time, the wells were further developed using compressed air to pressurize and displace water and sediment. A minimum of 10 volumes of water was evacuated from each observation well. If necessary, more water was evacuated to clear sediment. A layer of bentonite was placed approximately 6 inches below land surface to prevent surface water from infiltrating around the casing.

Water-Quality Sampling Procedures

Ground-water samples were collected for analyses of common inorganic and organic constituents from 48 wells from July through September 1984 and from 82 wells from August through November 1985. Additional analyses for detergents and volatile organics were performed in 1985 on ground-water samples from selected wells in the vicinity of Route 16, the main road through North Conway, New Hampshire.

To ensure that water samples were representative of the geochemical environment, the wells were pumped until a minimum of three casing volumes was evacuated and the pH, temperature, and conductivity had stabilized. After the wells were pumped, samples were collected with a submersible pump set 3 feet from the bottom of the well. A Johnson-

Keck model SP- 81-^ submersible pump was used in 1984 and a Fultz Enterprises submersible pump was used in 1985. In wells with yields too low to permit pumping with a submersible pump, samples were withdrawn using a Masterflex peristaltic pump or a PVC bailer. Grab samples were collected from domestic wells, springs, and pumpheads at municipal wells. :. --i

tffiSpecific conductance, pH, and temperature were measured in the;

field. Specific conductance was measured with Beckman Solu Brijdtpe b portable meters (type RB-5 in 1984, type RB-3 in 1985) . Field measurements of pH were made using a portable Leeds and Northrup model 74:0.7 meter; c3

Samples to be analyzed for dissolved constituents were field-b< filtered through a 0.45-micrometer filter and acidified with nitric acid. Samples were preserved according to specifications from the analyzing laboratory.

c.jAll samples from 1984 were analyzed by the laboratory of the Maine

Department of Environmental Protection. Samples collected from Fryeburg, Maine in 1985 were also analyzed by this laboratory. Samples collected from New Hampshire in 1985 were analyzed by the U.S. Geological Survey Central Laboratories in Atlanta, Georgia and Denver, Colorado.

Locations of sampling sites are shown on figure 2 The summaries of major chemical constituents in ground-water samples from Bartlett and Conway, New Hampshire are presented in tables 1-3. Analyses of 28 volatile organics in ground-water samples from OW14, OW17, OW30D, OW30S, OW25, and OW32 are summarized in table 4. No concentrations exceeded the detection limit of any compound. The analyses of major chemical constituents in ground-water samples from Fryeburg, Maine are summarized in tables 5-7.
