ABSTRACT

The U.S. Geological Survey collects, on a systematic 

basis, data needed to determine and evaluate the ground-water 

resources of Harrison County, Mississippi. Water samples 

were collected from 1997 to 2005 at selected wells screened 

in the Citronelle, Graham Ferry, Pascagoula, Hattiesburg, and 

Catahoula Sandstone aquifers and were analyzed for field 

properties (temperature, pH, specific conductivity, and color), 

total dissolved solids, chloride, iron, and manganese. The U.S. 

Environmental Protection Agency Secondary Drinking Water 

Regulation (SDWR) of 500 milligrams per liter for total dissolved solids was exceeded in water from three wells in the 

Hattiesburg aquifer and 12 wells in the Pascagoula aquifer. 

Chloride concentrations did not exceed the SDWR in any of 

the aquifers sampled, except for the Pascagoula aquifer where 

water in 10 wells had concentrations that exceeded the SDWR 

of 250 milligrams per liter. Iron concentrations in water from 

nine wells completed in the Graham Ferry and four wells completed in the Pascagoula aquifers exceeded the SDWR of 300 

micrograms per liter. Thirty water samples collected from the 

Graham Ferry and 12 from the Pascagoula aquifer exceeded 

the SDWR of 50 micrograms per liter for manganese.

INTRODUCTION

The U.S. Geological Survey (USGS) collects, on a 

systematic basis, data needed to determine and evaluate the 

ground-water resources of Harrison County, Mississippi. 

Water samples are collected from the aquifers underlying 

Harrison County to assess water-quality characteristics and to 

determine changes in water quality. The resulting information 

forms the foundation for many of the area’s water-resources 

management and planning activities and allows for the early 

detection of possible problems—for example, saltwater intrusion and contamination. Since April 1997, the USGS has 

collected water-quality samples from about 25 wells (of an 

approximately 100-well network), annually, for 4 consecutive 

years. Each year a different set of 25 wells was sampled. Then, 

during the fifth year, the original 25 wells were re-sampled, 

and the cycle was repeated. As much as possible, wells that 

were damaged, destroyed, abandoned, or otherwise no longer 

available for sampling were replaced in the network with wells 

completed in the same aquifer. Thus, the nominal 100-well 

network has included 104 wells.

Sites were selected to represent the major geologic units 

and depths at which wells have been completed in Harrison 

County (table 1). Two of the 104 wells were completed in the 

Citronelle Formation, 45 in the Graham Ferry Formation, 48 in 

the Pascagoula Formation, 8 in the Hattiesburg Formation, and 

1 in the Catahoula Sandstone; hereafter, in this report, these 

formations are referred to as the Citronelle, Graham Ferry, 

Pascagoula, Hattiesburg, and Catahoula aquifers, respectively.

This report presents results of the analyses of water 

samples collected from selected wells in Harrison County 

from 1997 to 2005. Temperature, pH, specific conductance, 

and color were monitored and recorded for all of the wells, 

and each well was sampled for chloride, dissolved solids, iron, 

and manganese. These constituents were compared to U.S. 

Environmental Protection Agency (USEPA) drinking-water 

standards for a frame of reference (U.S. Environmental Protection Agency, 2004).

METHODS OF SAMPLING AND 

ANALYSES

Water samples were collected (generally in April) from 

wells in Harrison County (fig. 1) from the Citronelle, Graham 

Ferry, Pascagoula, Hattiesburg, and Catahoula aquifers (in 

order from shallowest to deepest). The wells were pumped 

prior to sampling to withdraw enough water from the casing 

to allow the pH, and specific conductance to stabilize, thus 

ensuring the sample collected would accurately represent 

water from the aquifer. Final field (in situ) measurements of 

temperature, pH, and specific conductance were recorded. The 

samples were then shipped to the USGS National Water Quality Laboratory (NWQL) in Lakewood, CO, where the samples 

were analyzed using standard USGS procedures. Samples 

collected prior to 2004 were analyzed at the Water Quality 

Service Unit in Ocala, FL. Most samples were analyzed for 

color, pH, specific conductance, and concentrations of chloride, dissolved solids, iron, and manganese (Appendix I).

QUALITY ASSURANCE

 The USGS participates annually in the National Field 

Quality Assurance (NFQA) Program. This program tests the 

accuracy of the equipment used in the field and the technician’s skills at using this equipment. In addition, the USGS 

routinely collects quality-control samples to substantiate the 

validity of the data that the agency reports to its cooperators 

and the public. During the sampling period in April 2005, 

two replicate samples and one blank sample were collected. 

The replicate samples show the amount of variability in the 

samples and indicate any potential problems associated with 

the sampling process. The blank sample is collected from 

water that is prepared at the NWQL, free from any analytes 

being sampled for, and is used to identify any problems or 

deficiencies in field-cleaning procedures that could bias the 

results. Quality-control data are listed in Appendix II.

WATER QUALITY

Concentrations of chloride, dissolved solids, iron, and 

manganese for each well sampled since 1997 are presented 

graphically with box plots which show the distribution of 

the water-quality data. These four constituents were chosen 

because of their importance to the quality of drinking water. 

Chloride, along with dissolved solids, affects the taste of the 

water. Iron and manganese in water cause undesirable brownish-colored stains on porcelain plumbing fixtures and laundry. 

Water with high levels of iron and manganese can also have a 

foul taste and a bad odor. The results are discussed, by aquifer, 

below. The results may not be representative of the entire areal 

extent of the aquifers underlying Harrison County, but are representative of the aquifers at the sampled wells. Although the 

continued sampling effort is designed, with time, to produce 

enough long-term, distributed measurements to define waterquality trends for the aquifers, additional sampling will be 

necessary to determine the source and significance of changes 

in these water-quality measurements.

For most of these water-quality properties and constituents, no systematic change was detected. However, substantial 

changes occurred at a small number of individual wells. Additional sampling will be necessary to determine the source and 

significance of these changes.

Field Properties

The two wells in the Citronelle aquifer had depths of 70 

and 84 feet (table 1). A pH value of 4.8, which is lower than 

the USEPA SDWR range of 6.5 to 8.5, was recorded at one 

well. Specific conductivity ranged from 21 to 202 microsiemens per centimeter (μS/cm) in four samples, with a median 

value of 111 μS/cm. Color in five samples ranged from <5 to 5 

platinum-cobalt (Pt-Co) units, with a median value of 5 Pt-Co 

units.

Well depths in the Graham Ferry aquifer ranged from 63 

to 829 feet, with a median value of 467 feet in the 45 sampled 

wells (table 1). Field measurements of pH ranged from 5 to 

9.2 in 85 samples, with a median value of 7.7. Six samples 

were below the SDWR of 6.5, and eight samples were above 

the SDWR limit of 8.5. Specific conductivity ranged from 

20 to 540 μS/cm in 89 samples, with a median of 203 μS/cm. 

Color in 90 samples ranged from <1 to 50 Pt-Co units, with a 

median value of 9 Pt-Co units.

Well depths for the 48 wells sampled in the Pascagoula 

aquifer ranged from 476 to 1,320 feet, with a median depth of 

807.5 feet (table 1). Field measurements of pH ranged from 

5 to 10.2 in 98 samples, with a median value of 8.6. Four 

values were below the SDWR of 6.5, and 59 values exceeded 

the upper SDWR limit of 8.5. Specific conductivity ranged 

from 28 to 1,270 μS/cm in 101 samples, with a median of 310 

μS/cm. Color in 94 samples ranged from <1 to 50 Pt-Co units, 

with a median value of 10 Pt-Co units.

Well depths for the eight wells sampled in the Hattiesburg 

aquifer ranged from 1,140 to 1,860 feet, with a median depth 

of 1,560 feet (table 1). Field measurements of pH ranged from 

8.2 to 9.2 in 18 samples, with a median value of 8.8. Sixteen 

pH values exceeded the upper SDWR limit of 8.5. Specific 

conductivity ranged from 26 to 1,270 μS/cm in 20 samples, 

with a median of 436 μS/cm. Color in 20 samples ranged from 

<5 to 30 Pt-Co units, with a median value of 10 Pt-Co units.

The well sampled in the Catahoula aquifer had a total 

depth of 2,413 feet (table 1). The two field measurements of 

pH were 8.7, which exceeded the upper SDWR limit of 8.5. 

Specific conductivities in two samples were 593 and 595 μS/

cm. Color in two samples was 10 and 20 Pt-Co units.

Total Dissolved Solids

 Total dissolved-solids concentrations in four samples 

from two wells in the Citronelle aquifer ranged from 20 to 

162 milligrams per liter (mg/L), with a median value of 87 

mg/L. Although the two wells had large differences in total 

dissolved-solids concentrations, resampling during the fifth 

year of the cycle produced similar results. The lowest values 

of total dissolved-solids concentrations generally were from 

wells screened in the Graham Ferry aquifer (fig. 2). Total 

dissolved-solids concentrations ranged from 15 to 334 mg/L, 

with a median value of 160 mg/L. The highest values of total 

dissolved-solids concentrations generally were from wells 

screened in the Pascagoula aquifer (fig. 2). Total dissolvedsolids concentrations ranged from 16 to 990 mg/L, with a 

median value of 200 mg/L. Detections in water at 12 wells 

were above the SDWR of 500 mg/L for total dissolved solids. 

Total dissolved-solids concentrations in the Hattiesburg 

aquifer ranged from 20 to 704 mg/L, with a median value of 

266 mg/L (fig. 2). Concentrations in three wells exceeded the 

SDWR for total dissolved-solids. Total dissolved-solids concentrations of 328 and 346 mg/L were measured in 1997 and 

2001, respectively, for a single well screened in the Catahoula 

aquifer. Changes in total dissolved-solids concentrations over 

time in each aquifer were small, and no overall trend was 

observed.

WATER QUALITY 
Chloride

 Chloride concentrations for the Citronelle aquifer are 

limited to data for two wells. Each well was sampled twice, 

and the concentrations were nearly identical, ranging from 3.3 

to 3.4 mg/L.

 Chloride concentrations ranged from 2.2 to 18 mg/L, 

with a median value of 3.25 mg/L, for the wells screened in 

the Graham Ferry aquifer (fig. 3). All concentrations were 

well below the SDWR for chloride. For wells that have been 

sampled multiple times since 1997, the chloride concentrations have remained nearly the same from year to year, varying 

by 2 mg/L or less.

 The highest chloride concentrations generally were from 

wells screened in the Pascagoula aquifer. Chloride concentrations in the Pascagoula aquifer ranged from 2.0 to 430 mg/L, 

with a median value of 5.0 mg/L (fig. 3). Water in 10 wells 

exceeded the SDWR for chloride. Water-quality data since 

1997 indicate that although chloride concentrations generally have remained nearly constant for most wells screened in 

the Pascagoula aquifer, there was a slight increase with time. 

Site 86 (well M0790) had the largest difference over time, an 

increase from 310 mg/L in 1997 to 347 mg/L in 2005.

Chloride concentrations ranged from 1.9 to 230 mg/L, 

with a median value of 23.6 mg/L, for wells screened in the 

Hattiesburg aquifer (fig. 3). No concentrations exceeded the 

SDWR for chloride. For most wells with multiple samplings, 

chloride concentrations varied by less than 5 mg/L. The maximum change in chloride concentrations was a decrease of 11 

mg/L from 1997 to 2005 at site 100 (well M0711).

In 1997, a chloride concentration of 76 mg/L was 

measured in the single well screened in the Catahoula aquifer. When this well was sampled again in 2001, the chloride 

concentration was 75 mg/L.

Iron

Iron concentrations in water from the Citronelle aquifer 

were analyzed in samples from two wells through time. Each 

well was sampled twice, and the iron concentrations ranged 

from 6 to 70 micrograms per liter (μg/L) - well below the 

SDWR of 300 μg/L. The median value was 37 μg/L. Differences in concentrations during resampling were small and 

statistically insignificant.

 Iron concentrations ranged from less than 2 to 3,330 

μg/L, with a median value of 47.5 μg/L, for the wells screened 

in the Graham Ferry aquifer (fig. 4). Water in nine wells 

exceeded the SDWR limit for iron. For three wells that were 

sampled multiple times, iron concentrations increased substantially. Concentrations at site 5 (well A0049) increased from 

57 to 580 μg/L. An increase from 2,600 to 3,330 μg/L was 

recorded at site 10 (well D0019), and an increase from 1,500 

to 2,040 μg/L at site 22 (well G0247).

 The highest iron concentration (4,550 ug/L) measured 

was in the Pascagoula aquifer (site 54, well C0292). Water 

from the majority of samples from this aquifer had concentrations within the SDWR limit; with only four water samples 

exceeding the limit. Iron concentrations ranged from less 

than 2 to 4,550 μg/L, with a median value of 10 μg/L (fig. 

4). Since 1997, changes in iron concentration generally were 

small for most wells. The major exception to this is site 54 

(well C0292), where iron concentrations increased from 600 to 

4,550 μg/L from 1999 to 2003.

 Iron concentrations were low, ranging from 3 to 18 μg/L, 

with a median value of 6.5 μg/L, for wells screened in the 

Hattiesburg aquifer (fig. 4). For wells with multiple years of 

sampling, iron concentrations generally changed little.

 In 2001, an iron concentration of 26 μg/L was measured 

in well J0211, which is screened in the Catahoula aquifer.

Manganese

 Manganese concentrations in the Citronelle aquifer were 

determined for two wells. Each well was sampled twice, and 

manganese concentrations ranged from 6 to 48 μg/L, with a 

median value of 27 μg/L. Differences in manganese concentrations during resampling were statistically insignificant.

 Manganese concentrations ranged from less than 2 

to 297 μg/L, with a median value of 30μg/L, for the wells 

screened in the Graham Ferry aquifer (fig. 5). Concentrations 

exceeded the SDWR for manganese in 30 wells. For wells that 

were sampled multiple times since 1997, changes in manganese concentration were statistically insignificant.

 The highest manganese concentrations were from 

wells screened in the Pascagoula aquifer (fig. 5). Manganese 

concentrations ranged from 0.8 to 382 μg/L, with a median 

value of 8.25 μg/L. Water in 12 wells exceeded the SDWR for 

manganese. For most of the wells sampled in multiple years, 

the changes in manganese concentrations were statistically 

insignificant. However, a large increase in manganese concentration, from 20 to 382 μg/L, occurred at site 54 (well C0292).

 Manganese concentrations ranged from 3 to 26 μg/L, 

with a median value of 14 μg/L, for wells screened in the Hattiesburg aquifer (fig. 5). The SDWR for manganese was not 

exceeded in water from any of the sampled wells. For wells 

with multiple years of samples, manganese concentrations 

changed little with time.

In 2001, a manganese concentration of 30 μg/L was 

measured at site 115 (well J0211), screened in the Catahoula 

aquifer.
