Government Strategies To Combat Water Pollution

Water pollution is a pressing issue that governments worldwide are tackling through various measures. The Clean Water Act (CWA), enacted in 1972, forms the basis for regulating discharges of pollutants into water bodies and establishing quality standards. The Environmental Protection Agency (EPA) plays a pivotal role in implementing pollution control programs, setting wastewater standards, and developing national water quality criteria. States also have a significant role in managing nonpoint source pollution, setting standards, and identifying water bodies that fall short of these standards. To address water pollution, governments employ strategies such as providing financial assistance, developing action plans, restoring watersheds, and collaborating with local communities and industries to reduce pollution levels. The Biden-Harris administration, in particular, has made notable strides in protecting freshwater resources and ensuring access to clean drinking water for all.

Financial assistance for water quality projects

At the federal level, the United States Environmental Protection Agency (EPA) plays a pivotal role in providing financial assistance for water quality initiatives. The EPA offers various grant programs, such as the Drinking Water State Revolving Fund (DWSRF) program, which is a federal-state partnership that provides financial support to water systems and state safe water programs. The Bipartisan Infrastructure Law, for instance, allocated $2 billion in grant funding to address emerging contaminants in drinking water, including per- and polyfluoralkyl substances (PFAS). The EPA also administers the Water Infrastructure Finance and Innovation Act (WIFIA) program, offering long-term, low-cost supplemental loans for significant water and wastewater infrastructure projects.

Additionally, the EPA provides technical assistance and funding to Tribal communities to improve access to safe drinking water and proper sanitation facilities. The Safe Drinking Water Act (SDWA), amended through the 2018 America's Water Infrastructure Act, established the Drinking Water System Infrastructure Resilience and Sustainability Program. This grant program specifically targets small, underserved, and disadvantaged public water systems, helping them enhance their resilience to natural hazards, extreme weather events, and cybersecurity threats.

State governments also play a crucial role in offering financial assistance for water quality projects. For example, the California State Water Resources Control Board's Division of Financial Assistance (DFA) administers grant and loan funding for various initiatives. These include the construction of drinking water treatment and distribution systems, municipal sewage systems, water recycling facilities, and groundwater contamination remediation. Similarly, the Utah Department of Environmental Quality offers financial assistance for water quality and wastewater infrastructure projects within the state.

Local governments, such as the Washington State Department of Ecology, also contribute to financial assistance efforts. They manage capital funds, which are primarily passed on to local governments, tribes, and non-profits for projects that benefit water quality. This includes initiatives to prevent and reduce water pollution, clean up polluted waters, and engage citizens in protecting and restoring water quality.

Identifying high-risk locations for water sampling

Water pollution is a pressing issue that governments must address through various strategies and initiatives. One crucial aspect of tackling this problem is identifying high-risk locations for water sampling to ensure effective monitoring and remediation. Here are some key approaches and considerations for pinpointing these high-risk areas:

Utilizing Publicly Available Data: The Environmental Protection Agency (EPA) can leverage publicly available data to identify high-risk locations for water sampling. This includes integrating American Community Survey data on neighborhood characteristics with geospatial data. By analyzing demographic information, infrastructure data, and environmental factors, the EPA can prioritize areas that are more susceptible to water pollution.

Focusing on Vulnerable Populations: Identifying high-risk locations for water sampling also involves targeting areas with vulnerable populations. For instance, locations with childcare settings, schools, or communities with a high proportion of children require special attention due to the heightened health risks associated with lead exposure during developmental years.

Addressing Specific Contaminants: Certain contaminants, such as per- and polyfluoroalkyl substances (PFAS), have emerged as critical concerns in drinking water sources. PFAS, often referred to as "forever chemicals", persist in the environment and have been linked to severe health issues, including cancer and developmental problems in children. Therefore, identifying high-risk locations for water sampling should prioritize areas where PFAS contamination is suspected, especially near military bases and industrial sites.

Collaborating with Local Communities: Governments can benefit from engaging local communities, environmental groups, tribes, and citizens in the process of identifying high-risk locations. By incorporating feedback and local knowledge, governments can better understand specific pollution sources, such as agricultural runoff, stormwater discharge, or industrial waste, and target their water sampling efforts accordingly.

Developing Comprehensive Plans: To effectively identify high-risk locations, governments should develop comprehensive plans that encompass various water bodies, including rivers, lakes, marine waters, and groundwater. This involves setting water quality standards, monitoring programs, and establishing protocols for identifying and addressing non-compliance.

By employing these strategies, governments can more effectively identify high-risk locations for water sampling, enabling them to allocate resources efficiently, protect human health, and preserve the environment.

Clean Water Act and National Pollution Discharge Elimination System

The Clean Water Act (CWA) was established to address water pollution by regulating point sources that discharge pollutants into the waters of the United States. The Act created the National Pollutant Discharge Elimination System (NPDES) permit program in 1972, which is managed by the Environmental Protection Agency (EPA).

The NPDES program controls water pollution by implementing two levels of control: technology-based limits and water quality-based limits. The former sets effluent limitations, while the latter comes into effect if the technology-based limits are insufficient to protect the water body. The EPA authorizes state, tribal, and territorial governments to carry out the NPDES program, allowing them to handle permitting, administrative, and enforcement tasks. Currently, 47 states and one territory are authorized to implement the NPDES program.

The NPDES permit serves as a license for facilities to discharge a specified amount of pollutants into receiving waters under certain conditions. These permits are typically valid for a maximum of five years, after which the facility must reapply. There are two types of NPDES permits: individual and general. Individual permits are specific to a single facility, taking into account factors such as the type of activity and nature of the discharge. On the other hand, general permits cover a group of dischargers with similar characteristics within a given geographical location, offering a more cost-effective solution for permitting agencies.

The NPDES program applies to various entities, including construction sites, municipal, industrial, and commercial facilities. Any site or facility discharging wastewater or stormwater directly from a point source (e.g., pipes, ditches, or channels) into surface waters must obtain an NPDES permit. This requirement ensures that the nation's receiving waters meet specified Water Quality Standards (WQS). Compliance with the NPDES program is crucial, as violations can result in civil and criminal penalties.

Watershed restoration and sewage overflow

Watershed restoration is a key strategy employed by governments to address water pollution. This involves protecting and restoring aquatic ecosystems and wetlands in important geographic areas. For instance, the Environmental Protection Agency (EPA) in the United States has invested significant funds in projects aimed at rehabilitating the Lake Pontchartrain Basin, which has been polluted by stormwater, sewage, and agricultural runoff for decades. The EPA has also been urging municipalities with combined sewer systems to develop strategies to manage overflows and adhere to the Clean Water Act since 1994.

The Watershed Condition Framework (WCF) is another tool developed by the Forest Service to improve watershed health. The WCF provides a comprehensive approach for evaluating and prioritizing watersheds for restoration or maintenance. It involves strategically implementing integrated restoration, tracking and monitoring outcomes, and addressing conditions and risks that can be influenced to enhance watershed conditions.

Road restoration and decommissioning are crucial strategies to reduce watershed impacts from past development activities. This includes reconstructing roads alongside sensitive streams to enhance drainage and reduce sedimentation, as well as road storage and temporary closures. Channel modification due to historical logging, road building, rural residential development, and agricultural use can have adverse effects on streams, leading to issues such as chronic sedimentation, reduced stream shading, and modified floodplains and channel morphology, which negatively impact fish habitat and production.

Sewage overflow, or sanitary sewer overflow (SSO), occurs when untreated or partially treated sewage is released from a municipal sanitary sewer. This can happen when inappropriate materials, such as fats, oils, grease (FOG), and certain household products, are sent down the sewers. SSOs can contaminate water bodies, causing water quality issues, property damage, and threats to public health. They carry harmful bacteria, viruses, intestinal worms, and moulds, which can lead to various diseases, including mild gastroenteritis and severe ailments like cholera and hepatitis.

To prevent and mitigate the impacts of SSOs, several measures can be implemented. These include enlarging or upgrading sewer systems, pump stations, and sewage treatment plants; constructing wet weather storage facilities; and educating the public about proper sewer usage. Communities should also incorporate SSO prevention measures in their sewer system planning processes.

Removing and replacing lead service lines

In the United States, the Environmental Protection Agency (EPA) plays a crucial role in dealing with water pollution. The EPA undertakes large-scale watershed restoration, which involves protecting aquatic ecosystems and wetlands in important geographic areas. For instance, from 2002 to 2021, the EPA awarded around $31 million to projects aimed at restoring the Lake Pontchartrain Basin, which has been polluted by stormwater, sewage, and agricultural runoff for decades.

The EPA also works to address sewage overflow, an issue that affects about 700 municipalities with combined sewer systems. These municipalities have been instructed to develop plans to address overflows and comply with the Clean Water Act. The Clean Water Act, enacted in 1972 and amended in 1977, is the primary law governing pollution control and water quality in the United States. It establishes conditions and permitting for discharging pollutants into the nation's waterways.

To prevent oil spills from reaching navigable waters, the Oil Pollution Prevention regulation, enacted under the Clean Water Act, requires specific facilities to implement Spill Prevention, Control, and Countermeasure (SPCC) Plans. The EPA also regulates wastewater discharge from offshore oil and gas activities and sets technology-based effluent guidelines for different types of pollutants.

States also play a significant role in managing water pollution, particularly from nonpoint sources such as runoff from farms, parking lots, or streets. They set water quality standards, monitor water bodies, and develop Total Maximum Daily Loads (TMDLs) to address pollutants when standards are not met.

One specific area where the government is taking action to address water pollution is in the removal and replacement of lead service lines. Lead in drinking water can pose serious health risks, especially for young children and pregnant women. The Lead and Copper Rule, established by the EPA, mandates water systems to replace lead service lines under their control within 10 years.

The process of replacing a lead service line typically involves replacing it with a new copper service line. This can be done through open trench replacements or trenchless construction. Open trench replacements involve digging a trench from the home through the parkway to install the new service line and access the water main. Trenchless construction, on the other hand, runs the new service line underground, causing less disturbance to the surrounding area.

Several cities, such as Chicago and New York, have initiated programs to assist homeowners in replacing lead service lines. These programs may offer free or discounted replacement services to those who meet certain income requirements or live in specific neighbourhoods. Contractors are typically involved in the replacement process, and city inspectors review the installation to ensure it meets the required standards.
