Mining causes water pollution in a number of ways: * The mining process exposes heavy metals and sulfur compounds that were previously locked away in the earth. Rainwater leaches these compounds out of the exposed earth, resulting in "acid mine drainage" and heavy metal pollution that can continue long after the mining operations have ceased. * Similarly, the action of rainwater on piles of mining waste (tailings) transfers pollution to freshwater supplies. * In the case of gold mining, cyanide is intentionally poured on piles of mined rock (a leach heap) to chemically extract the gold from the ore. Some of the cyanide ultimately finds its way into nearby water. * Huge pools of mining waste "slurry" are often stored behind containment dams. If a dam leaks or bursts, water pollution is guaranteed. Perhaps the worst offense in the category of mining vs. water pollution causes: Mining companies in developing countries sometimes dump mining waste directly into rivers or other bodies of water as a method of disposal. Developed countries are not immune from such insanity: The US government in 2003 reclassified mining waste from mountaintop removal (a type of coal mining) so it could be dumped directly into valleys, burying streams altogether.

Many causes of pollution, including sewage, manure, and chemical fertilizers, contain "nutrients" such as nitrates and phosphates. Deposition of atmospheric nitrogen (from nitrogen oxides) also causes nutrient-type water pollution. In excess levels, nutrients over-stimulate the growth of aquatic plants and algae. Excessive growth of these types of organisms clogs our waterways and blocks light to deeper waters while the organisms are alive; when the organisms die, they use up dissolved oxygen as they decompose, causing oxygen-poor waters that support only diminished amounts of marine life. Such areas are commonly called dead zones. Nutrient pollution is a particular problem in estuaries and deltas, where the runoff that was aggregated by watersheds is finally dumped at the mouths of major rivers.

Pesticides that get applied to farm fields and roadsides—and homeowners' lawns—run off into local streams and rivers or drain down into groundwater, contaminating the fresh water that fish swim in and the water we humans drink. It's tempting to think this is mostly a farming problem, but on a square-foot basis, homeowners apply even more chemicals to their lawns than farmers do to their fields! Still, farming is a big contributor to this problem. In the midwestern United States, a region that is highly dependent on groundwater, water utilities spend $400 million each year to treat water for just one chemical—the pesticide Atrazine.
AT: Water Terror
1. Water terrorism has low probability and has never killed anyone in the US
EPA Dec 2003, "Response Protocol Toolbox: Planning for and Responding to Drinking Water Contamination Threats and Incidents" epa.gov/safewater/watersecurity /pubs/guide_response_module1.pdf [JWu]
While it is important to consider the range of possibilities associated with a particular threat, assessments are typically based on the probability of a particular occurrence. Determining probability is somewhat subjective, and is often based on intelligence and previous incidents. There are historical accounts of intentional contamination of drinking water supplies with biological or chemical contaminants, but most have been associated with wartime activities. The few documented accounts of intentional contamination of public water systems in the U.S. have not resulted in any reported fatalities. The American Water Works Association Research Foundation (AWWARF) is preparing a report on this subject (AWWARF, 2003). Based on these accounts, it would appear that the probability of a successful contamination incident on a drinking water system is relatively low. However, there has been a reported increase in the interest of various terrorist groups in biological and chemical weapons. Furthermore, some intelligence information indicates that terrorist organizations have considered water infrastructure as a possible target. Thus, the potential for such an incident does exist.
2. Water infrastructure is too large and complex to fully secure—no impact
Brock Meeks, award-winning journalist, chief Washington correspondent for MSNBC, Oct 23 03, "U.S water supply vulnerable", http://www.msnbc.msn.com/id/3340643/ [JWu]
Here’s the brutal truth: The nation’s water infrastructure is impossible to fully secure. The sheer vastness of the system with its “raw water” reservoirs and tens of thousands of miles of exposed aqueducts and pipeline with little or minimal security make it logically and fiscally impossible to completely police. To simply put fences around the three raw water reservoirs that the Indianapolis Water Company uses to feed that city’s water needs “would bankrupt the company,” says Peter Beering, IWC’s deputy general counsel.
The threat isn’t new. Industry experts have been crying in the wilderness for years trying to get the fractured water community to take the issue of terrorism more seriously. And in fact, the industry got a pre-September jolt of adrenalin that raised as many eyebrows as it did awareness.
