Some Helpful Links on Pharmaceuticals in Drinking Water

The Associated Press investigation on drinking water contamination by pharmaceuticals is a recent installment to the ongoing research about this topic. The U.S. government as well as other scientists have been studying this issue for some time. Here are some interesting links about the topic:

USGS What's In Our Wastewater and Where Does It Go? an array of studies and articles on contaminants in wastewater. "The U.S. Geological Survey (USGS) has implemented a national reconnaissance to provide baseline information on the environmental occurrence of "emerging contaminants" such as human and veterinary pharmaceuticals (e.g., fluoxetine and lincomycin), industrial and household wastewater products (e.g., p-nonyphenol and triclosan), and reproductive and steroidal hormones (e.g., equilenin and progesterone) in water resources."

How Healthy-Home Gardening Can Save Water and Reduce Pollution

Landscaping choices for your garden can contribute not only to a healthier lifestyle but also can help save water and reduce water pollution. Water conservation has become a significant issue for many communities, particularly for many U.S. states in the west and southwest.

Texas is also now facing water shortages and future potential water shortages as the population growth outpaces the local water supply. Texas depends upon a system of lakes and rivers to collect surface water from runoff. This runoff can become polluted with pesticides, fertilizers, herbicides, and sediment. It is important for Texas as well as other communities to conserve water and preserve water quality.

The Texas Extension Service--Tarrant County and the North Central Texas Council of Governments, along with other collaborators, created the Texas SmartScape® program, http://www.txsmartscape.com/ ,to teach homeowners and businesses how to select plants and maintain landscaping to reduce water usage and reduce the use of pesticides, herbicides, and fertilizers. This program is based upon principles included in Earthkind, xeriscaping, waterwise, and yard-smart programs that many other communities around the country now support.

Some of the basic ideas are:

1. Select native or locally-adapted plants. These plants require less water, fertilizers, and pesticides.
2. Whenever possible, avoid chemical pesticides, herbicides, and fertilizers and opt for natural alternatives.
3. Water the garden at night or early in the morning when there will be less evaporation from heat.
4. Use drip irrigation when possible.
5. Mulch plants to preserve soil moisture and add beneficial elements as it decomposes.
6. Avoid watering immediately after applying any fertilizer, even organic slow-release fertilizer.
