Well-poisoning is the criminal act of malicious manipulation of drinking water in order to cause illness or death, or to deny an opponent access to fresh water resources.
Well poisoning has been historically documented as strategy during wartime since Antiquity, and was used both offensively (as a terror tactic to disrupt and depopulate a target area) and defensively (as a scorched earth tactic to deny an invading army sources of clean water). Rotting corpses (both animal and human) thrown down wells were the most common implementation; in one of the earliest examples of biological warfare, corpses known to have died from common transmissible diseases such as bubonic plague or tuberculosis were especially favored for well-poisoning.
In 1462, for example, Prince Vlad III the Impaler of Wallachia utilized this method to delay his pursuing Ottoman Turk adversaries. Whilst retreating through Turkish-controlled Bulgaria, across the Danube River and back to the capital of Wallachia that same year, Vlad's army employed the poisoning of wells and other sources of water, as well as other scorched earth tactics en route to his country on both sides of the Danube, meaning that he deliberately polluted the water supplies of his fellow Romanians even at the cost of their lives if it slowed down his Muslim foes.
During the 20th century, the practice of poisoning wells has lost most of its potency and practicality against an organized force as modern military logistics ensure secure and decontaminated supplies and resources. Nevertheless German forces during First World War poisoned wells in France as part of Operation Alberich.
A few religions have laws condemning such scorched earth tactics. Most notably Islam, in its scripture, dictates that water-bodies may not be poisoned even during a battle and enemies must be allowed access to water.

Post-WWII plan by Jews to poison Germans
Accusations of well-poisoning have also been brought up against Serbs. Most notoriously, Serbs were accused of poisoning Kosovo Albanians. There are also accusations of well-poisoning as a part of the Srebrenica massacre.
Jewish forces used well poisoning during the Nakba, the ethnic cleansing of 1948, in order to ensure that Arabs could not return to villages they had been expelled from.
Naeim Giladi, an Iraqi Jew who had initially embraced Zionism, wrote:
Uri Mileshtin, an official historian for the Israeli Defense Force, has written and spoken about the use of bacteriological agents. According to Mileshtin, Gen. Moshe Dayan, former Israeli Defense Minister, gave orders in 1948 to remove Arabs from their villages, bulldoze their homes, and render water wells unusable with typhus and dysentery bacteria. [End note: "Mileshtin was quoted by the Israeli daily, Hadashot, in an article published August 13, 1993. The writer, Sarah Laybobis-Dar, interviewed a number of Israelis who had knowledge of the use of bacteriological weapons in the 1948 war. Mileshtin said bacteria was used to poison the wells of every village emptied of its Arab inhabitants."]
I heard a corroborating account myself from a technician with Mekorot, the Israeli Water Authority, who was testing a well near a construction site where I was working. I asked him what he was doing. Assuming I had fought in 1948 [ed - Giladi was only a bit too young] he said, "Don't you remember? We used bacteria in many places. Every village we occupied we put bacteria in the wells. Now we keep testing them to keep track of when it is safe to use them again."
In recent years, Israeli settler in the West Bank have been accused of well contamination. Cases include that of rotting chicken carcases found in a well at At-tuwani near Hebron in 2004, although suspected settlers blamed Arab infighting. In the following years, various NGOs reported similar occurrences, accusing settlers of deliberately contaminating cisterns.
In April 2013, Israeli settlers were accused of poisoning the water well of villagers south of Hebron. The villagers also complained of other forms of mistreatement.

To make sure the Arabs couldn't return to make a fresh life for themselves in these villages, the Israelis put typhus and dysentery bacteria into the water wells.".
