BASINS (Better Assessment Science Integrating point & Non-point Sources) with Climate Assessment Tool (CAT) Add In
BASINS is a multi-purpose environmental analysis system that integrates geographical information system (GIS), watershed data, and environmental assessment and modeling tools into one convenient package. BASINS CAT provides flexible capabilities for creating climate change scenarios. BASINS CAT can be used to assess the coupled effects of climate and land-use change, and to guide the development of effective management responses. 

Compliance Dashboard
The Compliance Dashboard shows trends in environmental compliance and enforcement for both surface waters and drinking waters across the US. The dashboards provide an easy-to-use summary of activities to answer questions like: which facilities are regulated, how many have been inspected or otherwise evaluated, and how many have alleged violations and have been subject to enforcement.

Environmental Justice Screening and Mapping Tool
EJSCREEN is an environmental justice mapping and screening tool that provides EPA with a nationally consistent dataset and approach for combining environmental and demographic indicators. EJSCREEN users choose a geographic area; the tool then provides demographic and environmental information for that area. All of the EJSCREEN indicators are publicly-available data. EJSCREEN simply provides a way to display this information and includes a method for combining environmental and demographic indicators into EJ indexes. Water related indicators include proximity to 'Risk Management Plan' sites, proximity to 'Treatment Storage and Disposal Facilities', proximity to 'National Priorities List' sites, and proximity to major direct water dischargers. Environmental justice indicators include 'Percent Low Income,' 'Percent Minority,' 'Less than Highschool Education,' 'Linguistic Education,' 'Individuals Under Age 5,' Individuals Over Age 64.'

Environmental Work
This page covers the environmental related efforts of Appalachian Citizens Law Center. ACLC has been involved in efforts to: force state and federal regulators to evaluate the potential impacts of proposed surface mines on human health; stop companies from mining on land without the full consent of all of the land’s owners; hold companies accountable for falsifying pollution discharge reports; and to hold accountable the state environmental protection agencies that are mandated to regulate industry pollution.

Mountaintop Removal Coal Mining
Over the last 15 years, AMA have led the legal battle against mountaintop removal mining and have worked hard to prevent the coal industry from externalizing environmental and economic costs onto the public. Our settlements and court victories have led to hundreds of millions of dollars spent on cleaning up dirty streams and protecting public health, and more than $15 million devoted to land trusts.

Egyptian Lacquer-Liberty Creek Solvent Contamination
HRWA recent sampling at the main seeps of groundwater into Liberty Creek found concentrations of the main hazardous chemical, toluene, at levels that have been found for the last 8 years.  These are well above EPA risk limits to protect public health and the environment.  More information about this issue and HRWA's efforts to address it are available on this website. In addition, the site links visitors to a 2013 report on the contamination

Sewage Treatment Plants
On this webpage HRWA explains why they believe their region needs a regional sewer and drinking water plan and provides wastewater recommendations. The site also provides a map of the Harpeth showing sewer treatment plants, drinking water plants, where contaminated groundwater is seeping into the river from the Egyptian Lacquer Plant, and where the river contains treated sewage or effluent.  

Watershed Science
This webpage is home to information about why the Harpeth does not not meet State Water Quality Standards in the summer and related science based efforts of the association. The page links visitors to an article about the high number of people who visit Harpeth River State Park, a 2006 HRWA Dissolved Oxygen Study and later 2007-2008 studies; and a 2006 Water Quality Analysis study funded by the organization. 

Water Quality and Sustainability
HRWA's Water Quality and Sustainability efforts focus on ensuring that policies and regulations are in place that support water quality. Efforts involve shaping growth and the built human landscape so that the ecological health of the river and its watershed is maintained and improved.  HRWA's expertise include watershed management and planning, stormwater management and regulations, clean water law and regulations, federal and state permitting and local planning and zoning, and land use planning.  This page includes links to HRWA's Protect Our River Campaign, Sewer work, Drinking Water efforts, Toilet to Tap, Egyptian Lacquer's point source pollution, Lowhead Dam Removal, and other science related efforts.

Clean Water
SELC seeks to protect the South’s cleanest waters, to rescue the most polluted ones, and to make sure there remains enough water flowing in our rivers and streams to support a healthy and diverse array of aquatic life. Priority Projects are listed on this webpage. 

Protecting Our Water and Health from Coal Ash
Nearly every major river in the Southeast has one or more lagoons on its banks holding slurries of coal ash from power plants. Containing hundreds of thousands of tons of toxin-laden waste, these pools are often unlined and have leaked arsenic, mercury, thallium, selenium, and other contaminants into the rivers and the underlying groundwater for years, if not decades. In Tennessee, SELC filed a lawsuit against Tennessee Valley Authority (TVA) for coal ash at the Gallatin Plant polluting the Cumberland River, which provides drinking water for 1.2 million residents downstream. To help Southerners find out more about risks to their communities, SELC and its partners launched SoutheastCoalAsh.org, a website that provides an interactive map and database of 100 coal ash impoundments.

Restoring the Harpeth River
In 2014, SELC and Harpeth River Watershed Association took legal action against three sewage treatment plants along the Harpeth River for ongoing permit violations and excessive sewage discharge in violation of the Clean Water Act. As a result, Harpeth Wastewater Cooperative and Cartwright Creek sewage treatment plants agreed to join a multi-stakeholder effort to restore the health of the Harpeth River. These utilities committed to expanding water quality monitoring in the river, developing a pollution management plan, and joining a diverse stakeholder group to work cooperatively on improving water quality. 

In 2016, SELC and HRWA successfully reached a settlement with the City of Franklin. In addition to new protections and monitoring for sewage discharges, part of the settlement agreement is a comprehensive study focusing on the entire Harpeth River watershed, the first such study in Tennessee. This landmark effort, in which SELC will be one of the participants, will assess the health and the risks to the Harpeth River and its tributaries to ensure the river meets water quality standards moving forward. 

Retiring Outdated Coal Burning Plants
SELC works to steer the Southeast away from its heavy reliance on highly polluting coal, participating in utility planning processes and working with state utility commissions to promote the retirements of outdated coal plants. Since 2010, we have helped secured plans or legally binding commitments to retire 30% of the Southeastern coal plant fleet.
