Nitrate—the oxidized form of dissolved nitrogen— is the main source of nitrogen for plants. It occurs naturally in soil and dissipates when the soil is extensively farmed. Thus, nitrogen fertilizers are applied to replenish the soil. However, these nitrates can be toxic, especially when they enter the food chain via groundwater and surface water.
For years, Rebecca Quintana had been a highly visible activist in the fight for safe drinking water, speaking regularly with reporters, rallying residents and helping to spark an unprecedented United Nations inspection in northern Tulare County. … Across a wide, rural swath of the San Joaquin Valley, people have long been unnerved about drinking the sporadically contaminated tap water.

This 15-minute video explains in an easy-to-understand manner the importance of groundwater, defines technical terms, describes sources of groundwater contamination and outlines steps communities can take to protect underground aquifers. Includes extensive computer graphics that illustrate these groundwater concepts. The short running times makes it ideal for presentations and community group meetings. Available on VHS and DVD.
The 28-page Layperson’s Guide to Groundwater is an in-depth, easy-to-understand publication that provides background and perspective on groundwater. The guide explains what groundwater is – not an underground network of rivers and lakes! – and the history of its use in California.
Nitrate—the oxidized form of dissolved nitrogen— is the main source of nitrogen for plants. It occurs naturally in soil and dissipates when the soil is extensively farmed. Thus, nirtrogen fertilizers are applied to replenish the soil. However, these nitrates can be toxic, especially when they enter the food chain via groundwater and surface water.
In California, the State Water Resources Control Board lists nitrate as one of California’s most challenging and growing water problems.
California boasts some of the finest quality drinking water on the planet. Every day, people turn on their tap and receive clean, safe water with nary a thought. But the water people take for granted isn’t so reliable for residents of small water systems and many disadvantaged communities (DACs) in rural agricultural areas.
