Healthy Waters

Healthy Waters

Clean water is one of the most important resources we have. Even if you’re not next to a stream or a lake, the water used in homes and on land – the way we live – still has serious impacts on the health of rivers, streams, wetlands, and lakes. Simple things including properly disposing of unwanted medicine, choosing personal care products thoughtfully, switching lawn care techniques, and avoiding single use plastics all help to keep waters healthy.

Programs & Initiatives

Indiana Master Watershed Steward Program

Many states around the country offer Master Watershed Steward programs that train volunteers in the basics of maintaining and enhancing water resources. In Indiana, the Master Watershed Steward program is open to all residents in Indiana and especially those who live, work, or play in the coastal counties of Lake, Porter, and LaPorte.

Unwanted Medicines

Unwanted medicine and personal care products can impact water quality—the water that we drink, bathe in, and use for recreation. Most of us do not use all of the medication and personal care products that we buy, and many of these chemicals are not regulated for safety, long-term health impacts, or environmental damage. Using the sink, toilet, or trash for disposal can put people, animals, and the environment at risk. So that raises the question—how do we safely use and dispose of these products?

Natural Lawn Care

Maintaining a healthy lawn can be an important aspect of homeownership, but sometimes conventional lawn care practices negatively impact our water resources. For example, fertilizers and pesticides that are used to grow thick green grass can run off your lawn into nearby stormwater drains and pollute local waterways. The solution is to create an attractive and environmentally-friendly landscape using natural lawn care principles promoted by IISG’s Lawn to Lake Midwest program. This program reduces polluted runoff in our waterbodies and enhances a lawn’s natural ability to thrive.

Nutrient Loss

The Illinois Nutrient Loss Reduction Strategy is a blueprint for improving water quality at home and all the way down to the Gulf of Mexico by reducing nitrogen and phosphorus losses from farm fields, city streets, and wastewater treatment plants. Released in 2015, the strategy outlines a suite of voluntary and mandatory practices that are expected to ultimately cut nutrient loading to rivers and streams by 45 percent.

Contaminants of Emerging Concern

Contaminants of emerging concern (CECs), also known as emerging contaminants, are substances found at low levels in the environment, but impacts on humans and aquatic life are unknown. These may be new chemicals or materials just recently found in the environment, due to improvements in detection techniques. Pharmaceuticals, personal care products, and endocrine disrupting chemicals (i.e., BPA, flame retardants) are the most well-known CECs. Research on CECs is key to ensuring healthy water resources—to determine ecosystem and human health effects, detectable and safe limits, and prevention and remediation techniques.

Microplastics & Marine Debris

Have you ever walked along the beach on Lake Michigan or the shores of a river and seen trash at your feet? You might be surprised to learn that the problem of plastic pollution goes deeper than what you’re seeing. The ecosystem impacts from microplastics and marine debris are a growing area of research, but we already know that microplastics and marine debris are a threat to our waterways. Scientists estimate that millions of tons of plastic are entering our lakes, rivers, and oceans every year, and much of this plastic pollution is preventable.
