Mikva’ot (Ritual Baths), the sixth tractate in the order of Tohorot in the Mishnah and the Tosefta. The tractate consists of ten chapters and deals wholly with the details of the mikveh. Chapter 1 classifies mikva'ot according to the grade of their purity and purifying effect, from ponds or ditches containing less than 40 se'ah and therefore invalid, to those of the highest grade, consisting of mayim hayyim ("pure spring water"). Chapter 2 discusses cases of "doubtful impurity" (e.g., if a person is not sure whether he has immersed properly or whether the mikveh was ritually fit), and then deals with the problem of mayim she'uvim ("drawn water"). Chapters 3 and 4 continue with various aspects of mayim she'uvim, e.g., how a mikveh invalidated by mayim she'uvim can be made rituallyfit, or how to direct rainwater from a roof into a mikveh without letting the water pass through a "vessel" in order to prevent the water's becoming mayim she'uvim. Chapter 5 deals mainly with the fitness of springs, rivers, and seas as mikva'ot. Chapter 6 is concerned with the question of a body of water linked with a mikveh, or two mikva'ot connected so that the water of the one "touches" the water of the other (hashakah), which is of great significance in the construction of the modern mikveh. Chapter 7 discusses the minimal requirement of 40 se'ah, especially whether snow, ice, etc. may complete that measure. Chapter 8 first deals with the halakhic difference between mikva'ot of the Holy Land and those of other countries; it then discusses problems touching on seminal issue and menstruation. Chapter 9 discusses the problem of hazizah ("interposition"). Chapter 10 deals with vessels or any other artifact requiring purification in a mikveh.
