Water Pollution's Impact On New York State's Environment

Water pollution in New York State is a pressing issue that has various negative impacts on the environment and public health. The state's water resources, including its lakes, rivers, and streams, are affected by a range of pollutants, such as microbial pathogens, nitrogen, phosphorus, organic carbon compounds, and toxic chemicals. These pollutants can have harmful effects on aquatic life and also pose risks to human health, especially when they contaminate drinking water sources. To address this issue, the Department of Environmental Conservation (DEC) in New York employs an integrated approach to manage sources of water pollution, reduce specific pollutants, and improve and protect water quality. They also sponsor events and provide educational resources to raise awareness and encourage public participation in environmental protection.

Stormwater runoff

The Town of Southeast, New York, has developed a Stormwater Management Program (SWMP) to mitigate the issue of stormwater pollution. The town's stormwater flows into six water bodies that have been designated as impaired by the New York State Department of Environmental Conservation. The program aims to reduce the amount of pollutants entering these water bodies during rain events.

The New York State Department of Environmental Conservation (NYSDEC) and the United States Environmental Protection Agency (USEPA) have identified stormwater runoff as a significant contributor to water pollution. According to the USEPA, half of the impaired waterways in the United States are affected by urban, suburban, and construction stormwater runoff. This type of pollution degrades the quality of drinking water, damages fisheries, and harms the habitats of plants and animals that depend on clean water for survival.

Nutrients such as phosphorus and nitrogen, often found in fertilizers, can promote the overgrowth of algae, deplete oxygen levels, and harm aquatic life. Bacteria from animal waste and failing septic systems can make lakes and reservoirs unsafe for recreational activities and drinking water sources. Oil and grease from vehicle maintenance can cause odour and sheen on water surfaces, making it difficult for aquatic organisms to absorb oxygen. Sediment from construction activities can cloud waterways and interfere with aquatic habitats. Additionally, the careless application of pesticides, herbicides, and fertilizers can have toxic effects on aquatic life and cause ecosystem imbalances.

To address stormwater runoff and its impact on water pollution, the NYSDEC has implemented regulatory requirements and permits for activities associated with stormwater discharges. These include the Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activities (MSGP), the General Permit for Stormwater Discharges from Municipal Separate Storm Sewer Systems (MS4 GP), and the General Permit for Stormwater Discharges from Construction Activities (CGP). These permits require facilities and operators to develop stormwater pollution prevention plans and take necessary actions to reduce the discharge of pollutants.

Industrial wastewater

Impact on Water Quality

Industrial activities can generate large volumes of wastewater contaminated with chemicals, heavy metals, and other pollutants. When this wastewater is improperly treated or discharged into water bodies, it can have detrimental effects on water quality. New York State, with its vast water resources, becomes vulnerable to such pollution, threatening the health of its aquatic ecosystems and the safety of its drinking water.

Environmental and Ecological Consequences

The discharge of industrial wastewater into New York's water bodies can have far-reaching consequences for the environment and local ecology. Contaminants from industrial processes can accumulate in aquatic ecosystems, leading to the destruction of habitats and the decline of fish and other aquatic species. This, in turn, disrupts the natural food chain and can have long-lasting impacts on the state's fishing industry and the ecosystems that depend on these water bodies.

Public Health Risks

The presence of industrial pollutants in water supplies poses significant risks to public health. Contaminants such as heavy metals, toxic chemicals, and pathogens can find their way into drinking water sources, potentially causing various health issues in the population. This is especially concerning in New York City, where older homes may have private plumbing made of lead, which can leach into the water supply.

Impact on Water-Dependent Industries

New York State's economy is closely tied to its water resources, with industries such as fishing, tourism, and agriculture relying on clean and abundant water supplies. Industrial wastewater pollution can have a detrimental effect on these sectors. For example, contaminated water can lead to fish kills, making it unsafe for both recreational and commercial fishing. It can also impact agricultural practices that depend on clean water for irrigation.

Infrastructure Damage

Climate Change Impact

Water pollution from industrial wastewater can also exacerbate the impacts of climate change. For instance, contaminated runoff from industrial sites can contribute to harmful algal blooms (HABs) in water bodies. These algal blooms are harmful to humans, animals, fish, and shellfish populations. With rising temperatures and changing precipitation patterns due to climate change, the frequency and intensity of HABs can increase, further degrading water quality and posing risks to both environmental and human health.

Nonpoint sources

Nonpoint source pollution is a major issue in New York State. It is caused by rainfall or snowmelt carrying natural and human-made pollutants into the state's lakes, rivers, wetlands, coastal waters, and groundwater.

Agricultural Sources

The agricultural sector is a significant contributor to nonpoint source pollution in New York State. Farms and livestock operations use about 70% of the earth's surface water supplies and are a serious water polluter. Agricultural pollution is the top source of contamination in rivers and streams, the second-biggest source in wetlands, and the third main source in lakes. It also contributes significantly to contamination in estuaries and groundwater. Every time it rains, fertilizers, pesticides, and animal waste from farms wash nutrients and pathogens such as bacteria and viruses into waterways.

Urban Sources

Urban areas are another major source of nonpoint source pollution in New York State. Used water from sinks, showers, and toilets, as well as commercial, industrial, and agricultural activities, contribute to wastewater. Stormwater runoff occurs when rainfall carries road salts, oil, grease, chemicals, and debris from impermeable surfaces into waterways. Oil leaks from cars and trucks also contribute to urban nonpoint source pollution.

Construction and Forestry Sources

Improperly managed construction sites and forestry lands can also cause nonpoint source pollution. Sediment from these sites can be carried by rainwater or snowmelt into nearby waterways, contributing to water pollution.

Septic Systems

Faulty septic systems can also be a source of nonpoint source pollution. Bacteria and nutrients from septic systems can contaminate groundwater and surface water, impacting drinking water supplies and causing environmental harm.

Overall, nonpoint source pollution is a complex issue in New York State, with many different sources contributing to the problem. Addressing nonpoint source pollution requires a range of strategies and the cooperation of various sectors, including agriculture, urban areas, construction, and forestry.

Water treatment plants

New York City, for example, has 14 Wastewater Resource Recovery Facilities (WRRF) that treat approximately 1.3 billion gallons of wastewater daily. These facilities serve the five boroughs of the city and consist of an extensive network of over 6,000 miles of sewer pipes, 135,000 sewer catch basins, and nearly 500 permitted outfalls for Combined Sewer Overflows. The treatment process involves transforming sludge, the solid byproduct of wastewater, into "biogas," a renewable energy source. The leftover solids, or "biosolids," are then dewatered and either landfilled or further processed for reuse as nutrient-rich soil amendments.

The state has set ambitious goals for the beneficial reuse of biosolids, aiming for zero-landfilling by 2030. This involves implementing diverse treatment methods such as composting, drying, gasification, and pyrolysis. New York City's WRRFs are also committed to conserving water, properly disposing of harmful products, and maintaining water quality in the city's waterways.

Atmospheric deposition

Acid deposition has had a significant impact on New York State's water bodies, particularly in the Adirondack and Catskill Mountains regions. The deposition of acids has led to an increase in the acidity of lakes, rivers, and streams, making them too acidic to support aquatic life. This has disrupted the reproductive cycles of freshwater macroinvertebrates, plants, and fish populations, with one species after another disappearing as water bodies become more acidic.

In addition to its effects on aquatic life, atmospheric deposition has also impacted the health of forests in New York State. Acid precipitation drains nutrients from the soil, causing adverse effects on highly sensitive forest ecosystems, especially the high-elevation spruce-fir forests. Evidence of decreased growth and dieback has been observed in the Adirondacks.

The combustion of fossil fuels, particularly in the Midwest, is a major contributor to the issue of acid deposition in New York State. While efforts have been made to reduce emissions, the recovery of affected water bodies and forests is a slow process. It may take decades or even centuries for some ecosystems to recover and support biological life again.

To address the issue of atmospheric deposition, New York State has implemented various programs and policies. The Acid Deposition Monitoring Network, established in 1985, has documented significant environmental improvements, with a 75% decrease in sulfate deposition statewide. Additionally, the Adirondack Long-Term Monitoring Program has been documenting changes in the chemistry of lakes, streams, and clouds in the Adirondack Mountains since the 1980s. These programs provide valuable data for understanding the impact of acid deposition and developing effective strategies to mitigate its effects.
