Protecting the Lakes from Pollution | Great Lakes Now

Introduction

The Great Lakes Now program is dedicated to addressing critical environmental issues that impact the Great Lakes region, which is vital for its ecology, local communities, and economy. This initiative focuses on three primary areas: the persistent algal blooms in Lake Erie, the coal ash pollution affecting neighboring water bodies, and the ongoing Flint water crisis that has attracted widespread attention and activism.

Lake Erie Algal Blooms

Ongoing Concerns

Background: Ten years after the Toledo drinking water crisis, Lake Erie continues to confront the challenge of toxic algal blooms. This ongoing environmental issue poses threats to drinking water safety and ecosystem health. Stakeholders Involved: The Environmental Law and Policy Center, among other environmental advocates, has initiated legal action against the U.S. EPA, demanding stricter regulatory measures to curb the conditions fostering algal blooms. Impact of Algal Blooms: The proliferation of harmful algal blooms not only compromises clean drinking water but significantly damages local fisheries, which are essential for both food supply and local economies. Additionally, these blooms detract from tourism and diminish the overall quality of life for residents in Northwest Ohio.

Scientific Insight

Ed Verham from LimnoTech notes that monitoring efforts indicate blooms can extend up to 12 miles offshore. The conditions fostering these blooms include excessive nutrient runoff from agricultural activities, elevated water temperatures, and calm weather patterns. Cyanobacteria: These blooms, primarily composed of cyanobacteria, thrive on nutrient overloads, leading to the production of harmful toxins like microcystin that pose serious health risks to humans and wildlife. Case Study: The 2014 Toledo water crisis starkly illustrated the risks associated with algal blooms, prompting significant upgrades to the Collins Park water treatment facility to better safeguard against future contamination.

Phosphorus Runoff

Agricultural Runoff: Research has identified agricultural runoff as the main source of phosphorus overload in the region. It has been documented that over 90% of the phosphorus found in Western Lake Erie can be traced back to agricultural practices, particularly from concentrated animal feed operations and fertilizers applied to corn and soy agricultural fields. Consequences of Over-Fertilization: The excessive use of fertilizers has led to a significant escalation in algal bloom incidents and intensity.

Regulatory Efforts

Goals: In an effort to combat this crisis, Michigan and Ohio have set ambitious targets for achieving a 40% reduction in phosphorus levels by 2025. Challenges: Despite the introduction of voluntary best practices for farmers, phosphorus levels in the lake have remained disappointingly stagnant, highlighting the complexity of reaching pollution reduction goals. Recent Findings: A promising development emerged in 2019 when a substantial decrease in phosphorus levels was recorded, prompted by farmers adopting significantly lower fertilizer application rates, suggesting real potential for effective change. Lawsuit Outcomes: As a result of ongoing legal actions, a consent decree now mandates the Ohio EPA to formulate a Total Maximum Daily Load (TMDL) for phosphorus levels in Lake Erie.

Federal and State Tensions

Tensions persist between federal agencies and state governments regarding the effectiveness of Ohio's TMDL. Agricultural representatives express concerns that stringent regulations might adversely affect farming operations. There is an increasing call for a detailed and enforceable pollution diet to systematically manage and reduce phosphorus discharges into the lake.

Coal Ash Pollution

Background on Coal Ash

Coal ash, a byproduct of burning coal for electricity generation, is notoriously toxic, containing harmful elements such as mercury, cadmium, and arsenic. There are more than 1,500 coal ash disposal sites across the United States, with 88 of these perilously situated near the Great Lakes, threatening their ecosystems.

Case Study: Waukegan, Illinois

In Waukegan, community members have expressed significant concerns regarding coal ash ponds that pose a direct threat to the health of Lake Michigan. For years, NRG Energy's power plant had faced community backlash for its pollution impacts on the local environment. Current Status: Recent interventions from the EPA have led to new regulations aimed at ensuring comprehensive cleanup of coal ash disposal areas, revealing a need for continued vigilance by communities and stakeholders.

Regulatory Changes

The newly implemented EPA rules close existing loopholes that previously allowed companies to evade cleanup obligations, and they establish clear timelines for remediation tasks which are slated for completion by 2028. Past experiences indicate that such remediation processes may carry hidden costs that inevitably affect consumers. Community Advocacy: Local advocates emphasize the critical need to hold companies accountable for their pollution and ensure the integrity of local water sources.

Flint Water Crisis

Historical Overview

The Flint water crisis erupted when the city switched its water source to the Flint River in search of cost savings. This transition resulted in lead leaching from aging pipes, leading to widespread lead contamination and a public health emergency. Lead Exposure Debate: Mark Edwards from Virginia Tech highlighted that early alarm regarding lead exposure shifted to a debate over whether the narratives surrounding the crisis exaggerated the reality of the situation. He noted that children in Flint faced lead exposure levels comparable to state averages, showing a disparity between media portrayals and actual data.

Proposed Solutions

To remedy the situation, there have been urgent calls for transparent and accurate communication with Flint residents about the health risks associated with lead exposure. Furthermore, there is a pressing need to acknowledge and rectify previous misinformation that contributed to community fears, alongside implementing ethical considerations in future communications.

Conclusion

The intricate interplay of politics, science, and community advocacy is pivotal in addressing the pressing environmental concerns that threaten water safety in the Great Lakes region. Establishing transparent dialogue is critical to alleviating fears and promoting effective action toward restoring the safety and health of these vital water bodies.
