We assessed the knowledge, attitudes and practices of some aspects of environmental health among residents of Ramallah and Al-Bireh district, Palestine. We found that few residents had attended sessions of awareness in environmental health but 83.6% were willing to participate in such events to raise public awareness. Most residents (91.2%) were aware of the relationship between water and human health, but only 39.7% reported that they or their families cleaned their water tanks more than once a year. Only 76.3% of the respondents reported that they always washed their hands before eating and only 67.0% reported that they checked the safety of food before eating. Only 33.7% felt reassured when they ate in restaurants. This was due to lack of cleanliness of the restaurants, staff and utensils, and the uncertainty regarding the source of the food.
