Water supply terrorism
Water supply terrorism involves intentional sabotage to a water supply system, through chemical or biological warfare, or infrastructural sabotage. Throughout military history and the history of terrorism, water supply attacks have been perpetrated by eco-terrorist and political groups, intending to scare, cause death, or drought.
Chemical & biological attacks
In 2000 in Queensland, Australia, police arrested a man for using a computer and radio transmitter to take control of the Maroochy Shire wastewater system and release sewage into parks, rivers and property.
LSD threats to the water-supply
Despite the fact that it’s impractical and very unlikely to produce any effect at large-scale, during the 60's a great deal of attention was paid to the notion that 60's counter-culture figures could intoxicate a whole city by putting a small dose of LSD in the water supply.
On 19 March 1966 London Life ran an interview claiming that anyone could take control of London in under eight hours by putting acid in the water system. DrDonald Johnson, claimed: “It is quite feasible that LSD could be used to take over a city or even a country. I agree if it were put into reservoirs, it would disable people sufficiently for an enemy to take control.” 
In truth it would take several vast LSD laboratories many years to generate even a fraction of the amount required to intoxicate a small town's water supply, which would also decay from sunlight, heat or chlorine in the system.
Infrastructural, or resource-based attacks
In Lusaka, Zambia, in 1999, a bomb destroyed the main water pipeline, cutting off water for the city 3 million.
Four incendiary devices were found in the pumping station of a Michigan water-bottling plant. The Earth Liberation Front (ELF) claimed responsibility, accusing Ice Mountain Water Company of stealing water for proﬁt.
In 2003 Jordanian authorities arrested Iraqi agents in connection with a failed plot to poison the water supply that serves American troops in the eastern Jordanian desert near the border with Iraq.
In 2006 Tamil Tiger rebels cut the water supply to government-held villages in northeastern Sri Lanka. Sri Lankan government forces then launched attacks on the reservoir, declaring the Tamil actions to be terrorism.
Draining of the Mesopotamian Marshes
The draining of the Mesopotamian Marshes occurred in Iraq and to a smaller degree in Iran between the 1950s and 1990s to clear large areas of the marshes in the Tigris-Euphrates river system. Formerly covering an area of around20,000 km2 (7,700 sq mi), the main sub-marshes, the Hawizeh, Central, and Hammar Marshes and all three were drained at different times for different reasons. Initial draining of the Central Marshes was intended to reclaim land for agriculture but later all three marshes would become a tool of war and revenge.
Many international organizations such as the U.N. Human Rights Commission, the Supreme Council of the Islamic Revolution in Iraq (SCIRI), the International Wildfowl and Wetlands Research Bureau, and Middle East Watch have described the draining as a political attempt to force the Ma'dan people out of the area through water diversion tactics.
