Comprehensive Overview of Water Quality in Kentucky

There are varieties of water resources in Kentucky and they are rivers, lakes and ground water although some are the most prominent like the Ohio River, the Kentucky River and different lakes like Lake Cumberland. Water plays an important part in the economy of that state and particularly in agriculture, tourism and recreation. The rivers and the lakes contain vital freshwater used as a source of drinking water, irrigation, and industry, among other functions necessary in the society and also serves as a source of fishing, boating, and other recreational activities.

Kentucky Division of Water (DOW) is instrumental towards monitoring and management of water quality in the entire state, water quality appraisal, and ensured conformance to environmental policies. The state also provides regular submissions to the EPA, including Integrated Water Quality Report, a detailed report that analyses the health of its waterways using the data collected on water quality.

Although Kentucky is blessed with adequate water supply, the state is struggling with various issues regarding water pollution such as nutrient pollution, industrial water contamination and continuous necessity of preserving its various aquatic ecosystems. These issues are already being exacerbated by increased urbanization, agricultural runoffs, and climate change, yet the state has undertaken many regulatory efforts, infrastructure investments, and outreach to the population to address the water quality in the state.

Kentucky Water Quality Challenges

1. Nutrient Pollution and Eutrophication

Nutrient pollution-excess nitrogen and phosphorus is one of the most serious water quality issues in Kentucky. the major source of these nutrients into water bodies is via agricultural run-offs, wastewater treatment facilities and urban storm-water. In the long run, nutrient overloads may result in eutrophication, whereby there are algae blooms, shortage of oxygen, and fish die-offs. This problem of nutrient pollution has penetrated the rivers, lakes, and reservoirs in the whole state of Kentucky as well as in the larger waters of the Ohio River and Kentucky River.

More specifically, nutrient-laden runoff has resulted in Lake Cumberland and other Kentucky recrescation lakes to be heavily affected by algal blooms. The state has been fighting this through the enhancement of agricultural best management practices, more wastewater treatment system, and less runoff in the city.

2. Chemical and Industrial Pollution

The state of Kentucky has an old industrial heritage, especially in coal mining industry, manufacturing and chemical manufacturing. Consequently, contaminants found in industry, like heavy metals (i.e., mercury, lead, and arsenic), toxic chemicals, and solvents, have long been an issue of concern on the water quality of the state. The rivers in Kentucky including the Kentucky and big sandy rivers have been especially found to be prone to chemical contaminant that can be hazardous to fish and human lives.

The state has gone a notch higher relating to regulation of industrial pollution by the Kentucky Pollution Discharge Elimination System (KPDES) that monitors the discharge of pollutants by industrial establishments. Nevertheless, the dangers of pollutants such as coal plants pollutants like polycyclic aromatic hydrocarbons (PAHs) and third parties with manufacturing plants run-off are still in question. Moreover, historical pollution of industrial processes remains a problem when it comes to ground water resources in certain areas.

3. Pathogen Contamination

Other key water quality issues caused by bacteria especially water run-offs, municipal storm run-offs and malfunctioning septic tanks are the other great threats to water quality in Kentucky. Water can become unsafe due to the pathogens that are found in water, like the E. coli. This is especially worrying in the rural setting where most of the families depend on their own wells and septic facilities that may not be well taken care.

To combat this pollution Kentucky has strived to strengthen the wastewater infrastructure and thus minimize pathogen contamination by carrying out water testing in popular recreational areas, provide advisories where necessary and the prescription of septic system maintenance.

4. Pollution and Erosion due to sediments

Sediment pollution has been a major issue in the state of Kentucky especially since the state is hilly and also has extensive agricultural activities. Construction site, deforestation and farming activities may cause huge amounts of sediments to be washed into water bodies and rivers and lakes, resulting in cloudiness of the water bodies, obstruction of red blood cells in fish gills and destruction of aquatic habitats. Errosion of water bodies tends to increase, since more forest areas get eroded due to mining or logging activities.

The state has implemented laws relating to the need to have erosion control procedures at construction sites and other land development activities; however this is still a problem dealing with many rivers and streams mainly in the eastern and central regions of the state.

State and Local Efforts to Improve Water Quality

1. Clean Water State Revolving Fund (CWSRF)

The state of Kentucky is a member of the clean water revolutionizing program or more precisely the clean water state revolving fund (CWSRF) program which offers low interest loans to individual communities as well as the municipal areas so as to enhance water clearing systems, the stormwater management as well as controlling the pollution that may have resulted due to the industrial outflows. Projects supported by this program include updating ageing wastewater systems, installing green solutions to urban run-off to better control and manage it.

Specifically, the cities like Louisville have employed CWSRF funds to enhance wastewater treatment process as a way of minimizing nutrient loading into the Ohio River. The CWSRF has been instrumental in the Kentucky endeavors to sustain and enhance water quality of the state.

2. Best Management Practices (BMP) in Agriculture

With its role in state economy, Kentucky has paid lots of attention to the agricultural Best Management Practices (BMPs) implementation to minimize the burden of water pollution occurring in the state because of the farming activities. Such BMPs practice includes crop rotation, buffer strips on rivers, conservation tilling, and fertilizer runoffs management plans. Farmers who administer BMPs have access to financial assistance by the Kentucky Division of Conservation to enhance the quality of water available in agricultural watersheds.

Moreover, Kentucky has created Kentucky Agricultural Water Quality Authority (KAWQA) that facilitates protection of the water quality and helps farmers in utilizing water quality management plans.

3. Watershed Restoration and Protection Initiatives

On the part of Kentucky, it is also taking an active role in slip-streams restoration projects meant to enhance the health of its streams, streams, and lakes. State concentrates on the activities to rectify the polluted waters, stabilize the streambanks and enhance fish habitats. One such program is Kentucky Stream Restoration Program which collaborates with the local communities to restore stream channels, mitigate sedimentations and enhance the aquatic ecosystems.

The local conservation agencies, of which the Kentucky Riverkeeper and the Kentucky Waterways alliance are an illustration, cooperate with the state bodies in order to establish the sources of pollution in particular watersheds which is frequently done using grassroots campaigns and community involvement.

4. Online Education and Awareness.

Heavy emphasis has been given to the aspect of public education and outreach by the state to promote improved stewardship of water. Volunteer programs such as Kentucky Adopt-a-Stream help volunteers monitor and report on water quality encourage participation in citizens and increase outreach about water-related issues. Kentucky also has activities such as the clean up services in the big Sandy river to have the locals engaged in maintaining clean and revitalized water sources in the state.

Impact of Climate Change on Water Quality

1. Rising Temperatures and Algal Blooms

Climate change should make average temperatures higher in Kentucky, and this may lead to an increase in the periodicity and intensity of algal blooms in reservoirs and lakes. Such blooms are usually as a result of excessive fertilizer and can reduce oxygen content in the water killing aquatic life. With the warming of the Kentucky waters, there will be an increased risk of harmful algal blooms (HABs) which can pose serious threats to the water quality and health of the residents of a state.

2. More Storms and Flooding

Climate change is causing significant rainfalls and frequent severe storms in Kentucky. These severe storms have the potential to overpower stormwater systems, and together with this, they cause rivers, streams and lakes to flood and be polluted with substances such as debris, waste, as well as chemicals. Flooding incidences are also a threat to the waste water treatment plants where the raw waste could be released into the local water bodies during high incidences.

3. Drought and water scarce

On the other hand, Kentucky can also record a higher number of and a longer duration of drought. This may put pressure on water supplies especially in regions which are dependent on surface water in rivers and lakes. The resultant effects of lower water levels is that the affected regions may experience a concentration of pollutants, water becomes scarce hence cannot be used in large quantities in agri- and industrial processes, and competition over the available sources of water hikes.Kentucky has been tackling water conservation measures and other alternative sources of water including rainwater harvesting and groundwater recharge schemes to address the effects of drought.

4. Effect on water supply and water quality in Eastern Coalfields

The eastern Kentucky mining operations are grounds of water quality demerits. Greater rainfall brought about by climate change could also add to the effect of acid mine drainage (AMD) that will be released when rainwater reacts with exposed coal and rock making the drainage acidic which would degrade surrounding streams and rivers. The issue of AMD is one of the greatest challenges facing the efforts at protecting the water resources in Kentucky.
