Comprehensive Overview of Water Quality

The water of North Dakota can be characterized by its specific geography, extremely low population density, heavy agricultural activities, and energy production sector. The state is also blessed with a treasure trove of water resources, starting with the Missouri River, Red River, and Devils Lake, as well as Lake Sakakawea, which is considered the greatest water body reservoir created by a man in the entire United States. The water bodies are very important as sources of drinking water, recreation, and irrigation and as habitats forwildlife.

Although the overall water quality of North Dakota can be ranked as fair to good, the state is still involved in continual problems within the context of surface and groundwater pollution. Surface water is particularly susceptible to agricultural runoff and industrial effluents, since the state depends on it greatly as the municipal drinking water.

Most farms, as well as several rural communities, have access to groundwater via the use of a personal well. Summing it all up, most of the aquifers are clean, but the state experiences the threat of salts, arsenic, and nitrate contamination in some of the wells. Moreover, there are many small water systems and private wells in North Dakota, and not all of them or administrative units may be able to test and treat water regularly.

The North Dakota Department of Environmental Quality (NDDEQ) uses its water quality statewide and is currently keeping a summarized list of impaired water bodies that are not in compliance with the Clean Water Act. Excess nutrients, sediments, pathogens, and high salinity are the most prevalent forms of impairment and are mostly found in the eastern and central areas. Nevertheless, North Dakota strives to make its water resources cleaner and healthier and passes this decision to future generations through the construction of water infrastructure, the creation of water conservation programs, and water awareness campaigns.

North Dakota Water Quality Challenges

North Dakota is exposed to various water quality issues, and most of them are related to the prevailing type of land usage, including agriculture. The state ranks among the highest producers of wheat, soybeans, corn, and livestock in the country. This productivity, however, lies in the main cause of nonpoint source pollution, especially caused by the nutrient runoff of fertilizers and animal wastes.

Damaging algal blooms (HABs) may occur due to fresh runoffs of nitrogen and phosphorus fields in the rain event that cause eutrophication in lakes or rivers. Such flowers deplete aquatic life, endanger the supply of drinking water, and cause health hazards to people and animals.

There is also the issue of salinity and soil erosion, particularly in the Red River Valley. Salty buildup in soils can be as a result of irrigation, shallow water tables, and poor drainage; the latter will move with surface water and groundwater. The wind and water sediments also affect the clarity of water, reducing it further, and introduce more of these pollutants into the lakes and streams.

The other burning problem is the effect of the energy development, oil and gas drilling in the Bakken region. In spite of the state enacting regulations to curb the contamination, reported cases during oil spills on brine (saltwater), oil, and drilling fluids have occurred. Especially dangerous brine spills are very salty, which makes the soil infertile and contaminates the groundwaters.

Another challenge is the issue of aging water infrastructure, particularly in rural states where the smaller water systems might be overwhelmed by outdated pipes, little treatment capacity, and no funds to upgrade them. Nitrates, arsenic, or bacteria are more likely to be present in the private wells that are not tested on a regular basis. Finally, the climate fluctuations have posed new water quality issues, as the heavier precipitation in portions of the country results in floods through overflow and runoffresponses, and shortages of water and stream flows in other places cause concentrations of pollution.

State and Local Efforts to Improve Water Quality

The state of North Dakota has achieved a lot in the quest of correcting its water quality problems by integrating state-based, local-based, and federal-based forces. The North Dakota Department of Environmental Quality (NDDEQ) takes the initiative in monitoring, regulation, and education of the population, cooperating with such agencies as the North Dakota Department of Agriculture, USDA-NRCS, and local Soil Conservation Districts.

One of the key initiatives is the North Dakota Nonpoint Source Pollution Management Program, which is sponsored by Section 319 grants from the EPA. This program is used to finance voluntary conservation practices in an effort to conserve runoffand safeguard water bodies. The encouragement of cover crops, buffer strips, nutrient management planning, and no-till farming activities that aid in curbing erosion and loss of nutrients is underway.

The oil and gas division of the North Dakota Industrial Commission has stringency in implementing regulations on the storage of wastewater, disposal of brine, and reporting of spills concerning oilfield matters. There are also remediation programs that are meant to clean up the contaminated sites and clean the damaged land and water sources.

At the city level, a number of cities and towns have put money into the enhancement of water treatment facilities and sewers with the objective of meeting the federal standards on drinking water. Drinking Water State Revolving Fund (DWSRF): Drinking Water State Revolving Fund (DWSRF) offers low-interest loans to the community as a part of enhancing water infrastructure.

Watershed projects such as the Upper Sheyenne River Watershed Project and the Red River Basin Commission unite stakeholders as the people work to resolve issues regional to the area, including high loads of sediments, excessive levels of nutrients, and floods. Such projects usually integrate scientific research, involvement of landowners, and practical conservation.

North Dakota is also involved in the Nutrient Reduction Strategy, through which voluntary targets are identified to cut nutrient pollution in the Mississippi River Basin. Even though North Dakota happens to be in the top, northward portion of the basin, the water that must flow in the state ultimately contributes to the Gulf of Mexico, which is a hypoxic, or dead zone.

One of the instrumental components of the state approach is educational outreach. North Dakota Water Education for Teachers (Project WET) and the citizen outreach programs of the NDDEQ furnish residents with guidelines and information about how they can take part in safeguarding water quality in the areas they live in by making small steps toward safe living.

Impact of Climate Change on Water Quality

Experience of climate change has already been felt in the state of North Dakota, and it is known that this condition will eventually affect the quality of the water in North Dakota. Among the most outstanding, there are the extremes in average precipitation, which heighten much more frequent flooding and surface runoff. Such occasions carry with them sediments, nutrients, and agrichemicals into the water systems, bypassing natural filtering capabilities and adding to pollutant levels.

Heavy rain may also overwhelm small town and rural stormwater and wastewater infrastructure, causing combined sewer overflows and unwanted releases of untreated water to rivers and streams. Concurrently, drought is increasingly becoming frequent and long-lasting in certain parts of the state. Drought lessens streamflow, decreases the lake level, and narrows up pollutants such as nitrates, salts, and pathogens. Low water levels also increase water temperatures, thus providing perfect conditions for harmful algal blooms and further stressing the aquatic life.

With the rising temperatures caused by the change in the climate, algae bloom duration is becoming extended and more intense in lakes and reservoirs due to longer growing seasons. This trend is very alarming, especially when it is in water bodies that are used as a drinking water supply or as recreation- and tourism-related waters. The variations in precipitation and freeze-thaw in the Bakken oil-producing region may worsen infrastructure insecurity, posing risks of a pipeline overpressure and a spill or leak in storage tanks. Moreover, North Dakota has a distinct geographical setting, in particular, the eastern Red River Basin, requiring it to be highly vulnerable to flooding, and it can be escalated due to climate-related changes in snowmelt processes and rain intensity.

In anticipation of these changes, North Dakota is starting to incorporate climate adaptation into the planning of water resources. This covers the upgrading of the infrastructure to resist heavy-duty weather, ensuring the health of soil and water retention in the farms, and improvement of the water monitoring networks to give real-time data to act quickly. The current study being done by universities and environmental organizations is providing input into policy and making investments based on resilient water management practices, which will become critical in a warmer and more unpredictable climate.
