Executive Summary

This report summarizes the Georgia results of a survey project to gauge water resource awareness, attitudes, and behaviors among citizens across the country. These results reflect the opinions and perceptions of the survey respondents but should not necessarily be viewed as representative of the entire state?s population. The results provide useful information for water resource extension professionals and others to consider in developing content and strategies for public education and outreach.

Beliefs about Water Quality

A large majority of survey respondents consider clean drinking water (94%), clean rivers and lakes (76%), and clean groundwater (75%) as very important. Respondents have greater confidence in the quality of groundwater (24% believe it is good or excellent; 10% believe it is good and improving) than they do in the quality of surface waters (10% as good or excellent; 17% good and improving) and ocean waters (8% as good or excellent; 10% good and improving).

Conditions Perceived to Affect Local Water Quality

The sources respondents cited as most responsible for water pollution problems are industry (45%), erosion from roads and/or construction (39%), new suburban development (34%), and stormwater (29%). Fewer than 20% of respondents cited agriculture (whether crop-based or animal-based) as being most responsible for local water pollution. However, more than 35% of respondents either suspect or firmly believe that agricultural sources such as fertilizers and pesticides are having some impact on water resources in their local area.

Protecting Local Waters

With regard to the protection of local waters, respondents expressed the highest level of confidence in local government officials, with 11% indicating that local government is performing this task very well and 43% reporting moderately well. State government performance received the next highest response ratings (6% very well; 38% moderately well). Somewhat less confidence was expressed in how the federal government (4% very well; 27% moderately well) and individual citizens (4% very well; 38% moderately well) are performing.

Water Quantity

Many respondents believe that adequate water quantity is either definitely (22%) or probably (22%) a problem for their communities currently. Approximately 40% of respondents believe that there is a low likelihood of their community meeting all resource needs in 10 years. Only 16% believe that there is a high likelihood of these future needs being met.

Learning about Water Issues

The most common source that respondents have relied upon to receive water resource information is local newspapers (65%). However, respondents indicated that they are more likely to use sources such as Web sites (46%); fact sheets, bulletins, or brochures (45%); or television (42%) than newspapers (38%) for learning about water resource issues in the future. Specific topics that relatively large numbers of respondents indicated an interest in learning more about included protecting public drinking water supplies (40%), water management in home and garden landscapes (28%), septic maintenance (26%), fish and wildlife water needs (26%), watershed management (25%), and well protection (21%).


The critical need for better water stewardship in Georgia has been underscored in recent years by a succession of severe droughts and floods as well as ongoing legal disputes with adjacent states and federal agencies about the allocation of available water within shared watersheds. Recognizing this need, the Georgia State Assembly in 2008 established a regional framework for water resource planning through the enactment of the Georgia Comprehensive Statewide Water Management Plan. A series of additional statewide water conservation measures were then put into effect with passage of the Georgia Water Stewardship Act of 2010. The Water Plan and the Stewardship Act both notably call for significant outreach and extension to encourage the voluntary adoption of water conservation practices among water utilities, industry, farmers, and the general public to reduce water demand. To be effective in this role, outreach and extension professionals clearly can benefit from having a deep understanding of the existing attitudes about water issues among target stakeholder groups.

In 2009, a survey project to gauge general perceptions and attitudes about water resource issues was conducted in Georgia as part of a national water quality survey effort. The survey instrument contained 59 questions developed by state water quality coordinators under the leadership of Robert Mahler, Professor of Soil and Environmental Sciences at the University of Idaho. The survey in Georgia was mailed to 1,998 randomly selected Georgia citizens using a Dillman four-stage mail survey methodology. A first mailing included a cover letter (Appendix A), the survey (Appendix B), and a postage-paid return envelope. A reminder card was then sent as the second mailing. After 20 days, a second survey with cover letter and a postage-paid return envelope were sent to those who had not yet responded. A final reminder card was then sent after 20 days to those who had still not responded. A total of 519 surveys were returned (a response rate of 26%) using this method. The survey distribution and response tabulation were also led by Professor Mahler.

This report summarizes key results from the survey for the purpose of assisting outreach professionals with their efforts to engage the public about critical water resource issues that face the state. The findings are reported as percentages of valid responses to each of the questions that are discussed (i.e., blank responses were not counted toward the total percentage for questions that required a response). Detailed analysis and interpretation of the Georgia responses were conducted collaboratively by faculty at the University of Georgia?s Carl Vinson Institute of Government, College of Environment and Design, and College of Agricultural and Environmental Sciences as well as staff from the Georgia Department of Natural Resources, Environmental Protection Division.

This survey project was conducted through the Southern Region Water Resources Project with funds provided by grant #2004-51330-02245 of the U.S. Department of Agriculture (USDA) 406 Water Quality Program. The project is a regional collaboration funded by the USDA National Institute for Food and Agriculture (NIFA) for the purpose of building partnerships to address water resource concerns among government agencies, business leaders, and other citizen stakeholders.

State Water Resources Overview

Georgia is drained by 14 major river basins (Map 1). The headwaters of all but 4 of these basins (Ochlockonee, Satilla, Suwannee, and St. Marys) are located in the Mountain, Valley and Ridge, and/ or Piedmont physiographic provinces, flowing over into the Coastal Plain at the Fall Line (see Map 2). Importantly, many of Georgia?s river basins are shared with neighboring states, including large river basins such as the Chattahoochee, Savannah, and Tennessee. Average annual rainfall for the entire state is approximately 51 inches. However, annual averages vary throughout the state, with some areas of the northern mountains receiving in excess of 60 inches, while Macon and Augusta receive only about 45 inches (Map 3). Water supply sources in Georgia also vary by region but are much more a function of differences in the underlying hydrogeology than in regional climate. The southern regions of the state located below the Fall Line obtain most of their supply from productive carbonate aquifers that contain high-quality groundwater. By contrast, the northern Piedmont and Mountain regions generally lack productive aquifers and therefore utilize surface waters such as rivers and man-made reservoirs as primary water supply sources.

State Demographics and Respondent Characteristics

Georgia?s resident population was 9.7 million as reported in the 2010 U.S. Census. The state?s population increased by 1.5 million in the decade since 2000. The largest metropolitan area is Atlanta? Sandy Springs?Marietta, with an estimated population of 5.5 million in 2009—more than 10 times the size of the next largest metropolitan area. The other metro areas wholly or partially in Georgia, by 2009 population, are Augusta?Richmond County, GA?SC (539,154); Chattanooga, TN?GA (524,303); Savannah, GA (343,092); Columbus, GA?AL (292,795); Macon, GA (231,576); Athens?Clarke County, GA (192,222); and Albany, GA (165,440). The per capita income of Georgia residents in 2008 was $34,849, substantially below the U.S. per capita income of $40,166. In 2008, there were 5.6 million jobs in the state, and the leading sectors of employment were state and local government (10.9%), retail trade (10.2%), health care and social assistance (8.3%), and manufacturing (7.7%). Figures 1 and 2 show the survey demographics.

Survey respondents were somewhat older (Figure 1), much more likely to be male (64% male, 36% female versus state average of 48% male, 52% female), and more highly educated than the average adult population of Georgia (Figure 2). These significant differences indicate that the results from the survey should not be inferred to represent the opinions of the general population as a whole. About 41% of respondents live inside a town or city limits, with the remaining 59% living in unincorporated areas. Approximately 4% of respondents reported that they are actively engaged in farming. Relatively similar numbers of respondents reported living in cities with populations greater than 100,000 (32%), intermediatesized communities of 25,000 to 100,000 (36%), and communities of fewer than 25,000 (32%). Most respondents can be categorized as long-term residents, having either lived in Georgia for their entire lives (39%) or resided in the state for more than 10 years (48%). Only 5% report having moved to the state in the past 5 years, with another 8% indicating that they have lived in the state for 5 to 9 years.

Water Quality: Importance of Water Issues

Respondents were given a list of water issues and asked to rate each according to its importance (Figure 3). All respondents reported that clean drinking water is either very important (94%) or important (6%). Similarly, there is a high level of concern for freshwater systems as indicated by attitudes toward clean rivers and lakes (76% very important; 23% important) and clean groundwater (75% very important; 23% important). Slightly lower, but still quite high, levels of concern were expressed for coastal issues such as clean marine water (67% very important; 31% important), clean bays and estuaries (66% very important; 30% important), and clean water for shellfishing (61% very important; 32% important). A majority of respondents gave a ranking of very important to water for agriculture (58%) and water for aquatic habitat (54%), with most other respondents ranking these issues as important (36% and 35%, respectively). A substantial majority of respondents ranked several other human uses as either very important or important, including municipal use (46% very important; 41% important), power generation and other industrial uses (41% very important; 47% important), water for recreation (38% very important; 40% important), and water for household landscapes (26% very important; 41% important). Significant levels of concern were also expressed for interstate transfer or sale of water (25% very important; 30% important), within-state transfer or sale of water (25% very important; 32% important), and coastal hypoxia (28% very important; 24% important). However, knowledge or concern about this last set of issues appeared to be relatively low among respondents, as indicated by the comparatively high rate of “no opinion” responses (30%, 32%, and 41%, respectively).

Figure 3:
Importance of Water Issues

Drinking Water

As shown in Figure 4, a majority of total respondents receive their water from a public supply source, including 57% from a municipal public source and 11% from a rural water district. Approximately 17% depend on private water systems (private wells, river, pond, or lake), and 13% use bottled water as their primary drinking water source. Not surprisingly, a significant percentage of respondents living outside city limits reported using wells and other private sources as their drinking water source (28%), while use of private water sources was quite rare among those living in cities (less than 1%). However, most respondents living outside cities rely upon a public supply source, whether municipal (44%) or from a rural water district (15%). A slightly higher percentage of respondents living in cities (15%) use bottled water compared with those living in unincorporated areas (12%).

4: Drinking Water Sources

Approximately 88% of respondents believe that their home drinking water is safe to drink, and most (68%) report that they are satisfied with their drinking water (Figure 5). However, 16% report that they are not satisfied with their home drinking water. About 38% of respondents reported having a home water filter, and 5% have home water treatment systems. A little over half (51%) of respondents indicated that they often use bottled water for drinking purposes.

5: Drinking Water Attitudes and Behaviors

Respondents served by private water supply sources gave their water somewhat higher ratings for safety (95%) and satisfaction (88%) than those who use public water supplies (92% safety; 77% satisfaction). Those respondents who use bottled water reported the lowest ratings for their home tap water (63% safety; 24% satisfaction). While only 12% of total respondents reported having their home drinking water tested, a relatively large percentage (40%) of those with private water supplies conduct tests. By way of comparison, only 5% of those living in cities and served by a public water supply source reported testing their water.

Beliefs about Water Quality

Respondent attitudes about water quality were generally more positive for groundwater than for surface water and ocean water (Figure 6). However, responses for both groundwater and surface water varied considerably according to where respondents live (Figures 7 and 8). Most significantly, only 13% of respondents living inside city limits believe the quality of groundwater in their area to be good or excellent, while approximately 32% percent of those who live outside cities believe that the quality of groundwater in their area is good or excellent. Conversely, 28% of respondents in cities report good but deteriorating (10%), fair (15%), or poor (3%) groundwater quality compared with 20% living outside cities (good but deteriorating 12%, fair 6%, and poor 2%). However, a high proportion of respondents living both inside cities (48%) and outside city limits (38%) indicated that they do not know or have no opinion about groundwater quality in their area. Relatively few respondents (19%) reported “do not know” or “no opinion” about surface water. Notably, only 10% of total respondents indicated that surface waters in their area were of good or excellent quality, including only 6% in city limits and 13% outside city limits. A little more than half of total respondents (54%) indicated a belief that quality of surface waters in their area was deteriorating, fair, or poor. This percentage included 59% of those living in cities and 51% outside cities. Respondent attitudes toward the state of the ocean were even less positive, with only 8% reporting ocean water quality in the southern states as good or excellent. The largest percentage of respondents indicated their belief that ocean water quality is good but deteriorating (31%), with large percentages reporting either fair (15%) or poor (13%). There was very little difference in attitudes about ocean water quality between city respondents and those living in unincorporated areas (not graphed).

Conditions Perceived to Affect Local Water Quality

When asked about their knowledge or suspicions about how specific pollutant sources may be affecting local water quality, the largest percentage of respondents reported “do not know” for all categories (Figure 9). However, some general trends about the types of pollutant sources that respondents are concerned about can be discerned. For example, a comparatively large percentage of respondents reported having concerns Respondents were also asked to indicate the top three sources of existing pollution problems for rivers and lakes in Georgia from a list of possible sources (Figure 10). The highest percentage (44%) cited industry, with erosion from roads and/or construction (39%), new suburban development (34%), and stormwater runoff (29%) also viewed as major problems. A somewhat greater percentage of those living in cities cited industry (47%) and new suburban development (37%) than did those living in unincorporated areas about pollutants typically associated with agricultural operations, with nitrate fertilizers most commonly cited as a source of both suspected (31%) and known (6%) water contamination, followed closely by pesticides (31% suspected; 5% known) and phosphate fertilizers (30% suspected; 5% known). Respondents showed a broad level of concern about a wide variety of other contaminants, including algae (21% suspected; 4% known), pathogens (20% suspected; 4% known), heavy metals (18% suspected; 4% known), pharmaceuticals (18% suspected; 4% known), septic systems (18% suspected; 4% known), minerals (18% suspected; 3% known), and petroleum products (16% suspected; 3% known). Of least concern was contamination from mining operations (5% suspected; 2% known) and salinity (5% suspected; 2% known).

Figure 10: Sources Cited as Most Responsible for Surface Water Pollution

(43% for industry; 34% new suburban development). Similar percentages of total respondents cited cropbased agriculture (18%), wastewater treatment plants (18%), runoff from home landscapes (18%), landfills (17%), and septic tanks (17%). Sources viewed as somewhat less problematic include animal agriculture (14%), forestry (8%), and oil wells/mining (8%). By far the least cited source was military bases (2%). Although opinions about pollution sources among city residents and those living in unincorporated areas were generally similar for each category, somewhat different response rates were found for septic tanks (11% in cities; 21% in unincorporated areas) and runoff from home landscapes (21% in cities; 15% in unincorporated areas).

Water Quantity

The severe drought of 2007?2008 brought renewed attention to the fragility of Georgia?s freshwater supply sources, particularly within the Piedmont and Mountain watersheds that serve the heavily populated and fast-growing metropolitan Atlanta region. Given this context, it is perhaps unsurprising that almost half of respondents (48%) reported that they view the likelihood of prolonged drought as increasing, while only 7% reported that prolonged drought is becoming less likely (Figure 11). When specifically asked if global warming will affect rainfall amounts in their local area, a little over a quarter of respondents expected either a slight (15%) or significant decrease (12%) in rainfall, with another quarter (26%) expecting no change at all and the largest percentage (37%) indicating that they do not know (Figure 12).

Figure 11: Attitudes toward Likelihood of Prolonged Drought
Figure 12: Attitudes toward Effect of Global Warming on Rainfall

Respondents were asked to rate the extent of water quantity concerns in their local area (Figure 13). Almost identical percentages of respondents believe water quantity is a problem (44% definitely or probably a problem) as do not believe it is a problem (44% definitely or probably not a problem). Confidence was, however, significantly stronger among respondents who believe water quantity is a problem, with 22% reporting “definitely.” By contrast, only 11% of those who do not believe water quantity is a problem reported “definitely.” Respondents living in cities showed significantly higher levels of concern about water quantity (26% probably; 25% definitely a problem) versus respondents living in unincorporated areas (20% probably; 20% definitely a problem).

Figure 13: Extent of Water Quantity Concerns

Future outlook regarding water resources was fairly pessimistic. The highest number (40%) of respondents reported that there was a low likelihood of their local area being able to meet all water resource needs in 10 years, while only 16% believe that there is a high likelihood of future water needs being met (Figure 14). Attitudes among respondents living in cities (13% high likelihood; 37% medium likelihood; 43% low likelihood) were somewhat more pessimistic than those of respondents living outside city limits (19% high likelihood; 36% medium likelihood; 38% low likelihood).

Figure 14: Likelihood of Local Area Meeting Water Resource Needs in 10 Years

Protecting Local Waters

Participants were asked to rate the performance of the federal government, state government, local governments, and individual citizens in protecting the water resources of their communities (Figure 15). The most favorable responses were given for local governments (county, city, or town), with more than half of respondents reporting that local governments are either fulfilling their water protection responsibilities very well (11%) or moderately well (43%) and relatively few expressing negative views (17% somewhat poorly; 7% very poorly). The next highest ratings (6% very well; 38% moderately well) were for state government. The federal government (4% very well; 27% moderately well) and individual citizens (4% very well; 27% moderately well) received the lowest ratings for their ability to protect water resources. Similar percentages of respondents had negative views about how well the federal government (24% somewhat poorly; 12% very poorly), state government (25% somewhat poorly; 10% very poorly), and individual citizens (26% somewhat poorly; 8% very poorly) are fulfilling their water resource protection responsibilities.

Figure 15: Group Performance in Protecting Local Water Resources

In a series of questions in which respondents were prompted to rank the importance of specific water resource protection actions, all of the specific actions received a ranking of important or very important by at least 75% of respondents (Figure 16). The action that received the highest ranking was water quality monitoring to detect pollution (56% very important; 35% important), followed very closely by improved wastewater treatment (55% very important; 36% important). Other actions that respondents regarded as especially important included educating municipal officials (50% very important; 39% important), residential water conservation (48% very important; 40% important), and building new water storage structures (45% very important; 40% important). While still generally supportive of the actions, respondents were least concerned about the importance of improving home and garden practices (33% very important; 45% important), better management of recreation activities (33% very important; 43% important), and treatment of stormwater runoff (31% very important; 44% important).

Figure 16: Importance of Water Resource Protection Actions

Personal Natural Resource Ethics and Actions

Survey participants were asked to chart their overall opinion about environmental issues on a scale ranging from total natural resource use to total environmental protection, with the middle point indicating an equal balance between use and protection (see Question 46, Appendix B). While most respondents placed themselves in the equal balance category (57%), significantly more favored total environmental protection (27%) than supported total resource use (16%). Interestingly, slightly higher percentages of respondents living in cities identified themselves on the far ends of the spectrum (17% total use; 30% total environmental protection) compared with residents living in unincorporated areas (14% total use; 25% total environmental protection). However, the equal balance category still characterized the majority of respondents in both cities (53%) and outside cities (61%).

The survey contained a series of questions that explored the various sources of information that respondents use to form their beliefs about environmental issues (Figure 17). By far the most influential source in terms of changing respondent minds about the environment was news coverage (cited by 52%). Conversations with other people (32%), firsthand observations (28%), and financial considerations (18%) were the next most influential. Relatively few changed their minds because of classes or presentations (10%), attending public meetings or volunteer activities (8%), or hearing a speech by a public official (4%).

Figure 17: Influence of Information Sources on Views toward Environmental Issues

Participants were also asked about ways they may have adjusted their own behavior to conserve water or preserve water quality (Figure 18). The most cited action in the responses was changes in the frequency of watering yards (67%). Surprisingly little difference was found between the percentage of respondents living in a city (66%) and those living in unincorporated areas (68%) who reported changing their yard-watering frequency. Adoption of new technologies such as low-flow toilets was cited by a relatively large number of respondents (40%), while somewhat lower percentages reported changing the use of pesticides, fertilizers, or other chemicals (28%) or changing the way their yard is landscaped (24%). The fewest reported having their septic tanks pumped (16%), although, as would be expected, response rates regarding septic tanks varied significantly between those who live in cities (8%) and those in unincorporated areas (21%).

Figure 18: Actions Taken to Conserve Water or Preserve Water Quality

Few respondents reported participation in various civic activities (not graphed). The highest number (9%) participated in county, municipal, or township meetings, with somewhat smaller percentages participating in lake, river, bay, wetland, or watershed protection groups (7%), volunteer water quality monitoring (6%), and the Master Gardener program (5%).

Learning about Water Issues

Survey participants were given a detailed list of media options and communication networks and asked whether they have received water resource information from these sources (Figure 19). By far the most common source of information about water resources was local newspapers (56%). Network television (45%) and public television (43%) were the next most common sources of media information, with a similar percentage citing friends and family (43%). A little more than one-third listed radio (37%), approximately one-third included national media sources such as major newspapers (34%) and cable television (33%), and somewhat fewer cited magazines (29%). Environmental agencies (i.e., governments) were listed as an information source by approximately one-third of respondents (32%), while about a quarter cited nongovernmental environmental groups (25%). The lowest percentage of respondents reported receiving water resource information from universities (20%), extension (19%), or schools (14%).

Figure 19: Previous Sources of Water Resource Information

When asked about their desire to learn more about a variety of specific water resource topics (Figure 20), most respondents cited protecting public drinking water supplies (40%). A relatively large number of respondents desired having more information about household management issues such as home and garden landscaping (28%), septic system maintenance (26%), and private well protection (21%). Approximately a quarter cited a desire to learn about fish and wildlife water needs (26%) and watershed management (25%), while approximately 20% indicated an interest in water policy and economics. All other categories were cited by fewer than 20% of respondents, with the least amount of interest shown for farm-related issues such as landscape buffers (15%), irrigation management (13%), and animal waste management (10%).

Figure 20: Water Resource Areas of Interest

Respondents also were asked to note the types of learning opportunities they would most likely utilize in the future (Figure 21). The most commonly cited opportunity was visiting a Web site (46%), followed closely by reading fact sheets, bulletins, or brochures (45%) and watching TV coverage (42%). A significant number also were likely to read a newspaper article or series (38%). There were fewer responses to all other categories (less than 15%). Respondent age had a strong effect on the likelihood of using various media sources. For example, only 26% of those over age 65 were likely to use the Internet, with a much higher relative percentage among this age group citing fact sheets (51%) or newspaper articles (47%). Respondents under 50, by contrast, were much more likely to use a Web site (64%) while being somewhat less likely to use fact sheets (44%) and much less likely to use newspapers (32%).

Figure 21: Sources for Learning More About Water Quality


Respondent answers indicated a broad level of concern and knowledge about water resource issues. Not surprisingly, maintaining abundant and clean drinking water clearly emerged as an imperative issue. Very high levels of concern were also expressed for protecting the water quality of streams, lakes, and coastal waters. While a large majority of respondents believe that their drinking water is safe, many believe that there are major problems with the state?s groundwater, surface waters, and coastal waters. Respondents also showed a high level of support for programs to protect these resources and expressed confidence in the ability of local governments in particular to carry out this mission.

The survey responses also can be used to help outreach and extension professionals target ways to educate the general public about less-known issues. For example, high percentages of respondents indicated that they had little to no knowledge of water transfers (whether in-state or among states). Because water transfers are likely to become increasingly important (and potentially controversial) in Georgia in the near to mid term, building public understanding may allow citizens to engage with community leaders in constructive decision making. Likewise, respondents showed little understanding about coastal hypoxia. In this case, outreach and extension professionals may give priority to educating citizens on this phenomenon and the impact it can have on local communities and the state?s economy.

There is also significant potential for the survey results to be used as a basis for extension professionals to refine their communication strategies. Survey questions about media habits suggest the need for extension specialists to communicate important information about water resource conservation using a wide variety of media outlets, thus allowing for a larger percentage of the public to receive this information than can be achieved through traditional extension publications and activities alone.

Moving forward, it is clear that Georgia, like most other states and regions, will continue to face major water resource challenges over the coming years. Careful assessment of public knowledge and attitudes about water resource issues will remain critical as a mechanism for understanding new trends in opinions and perceptions as well as identifying areas in which outreach and extension professionals may be most needed to provide objective and trusted sources of information. We hope that the results of this study prove useful in serving these ends.
