PART Env-Ws 1102 DEFINITIONS

Env-Ws 1102.01 Definitions.

(a) "Bromine" means an element which is sometimes used in bathing facility water purification. A dark, heavy, reddish-brown liquid in its natural state, bromine is closely related to chlorine.

(b) "Bromine equivalent to chlorine" means the concentration of bromine equal to that of chlorine. This value can be calculated by multiplying parts per million (ppm) or milligrams per liter (mg/L) chlorine by 2.25.

(c) "Cartridge filter" means a filter that uses a fabric-like cartridge as a filtering medium.

(d) "Chloramines" mean compounds formed when free chlorine combines with nitrogen or ammonia from substances including but not limited to urine, suntan oils, hair spray or perspiration. The formation of chloramines can cause skin and eye irritation and has a strong, objectionable odor.

(e) "Chlorine" means a heavy, green, highly poisonous gas in its elemental, or naturally occurring, state. Compressed in liquid form and stored in heavy steel tanks, hypochlorite can be used in bathing facilities as a disinfectant.

(f) "Chlorine demand" means the amount of chlorine needed to oxidize organic matter present in bathing facility water, such as chloramines, susceptible bacteria and algae.

(g) "Chlorine residual" means the amount of available chlorine remaining in bathing facility water after the chlorine demand has been satisfied.

(h) "Communicable disease" means illness due to an infectious agent or its toxic products, which may be transmitted directly or indirectly to any person from an infected person, animal, or arthropod, including insecta and arachnida, or through the vehicle of an intermediate host, vector or the inanimate environment.

(i) "Deck" means the area immediately adjacent to or attached to a bathing facility that is specifically constructed for use by patrons for sitting, standing or walking.

(j) "Diatomaceous filter" means a pressure or vacuum type filter that uses a white powder derived from fossilized organisms called diatoms as a filtering medium.

(k) "Division" means the division of water of the department of environmental services of the state of New Hampshire.

(l) "Fence" means a structural safety boundary intended to prevent unauthorized entry from the outside, not intended to be sat, walked, or climbed on.

(m) "Flow-through pool" means a natural or artificial pool to which the water is piped by pump or by gravity but water flow from the pool is not returned to the pool.

(n) "Free residual chlorine" means that portion of the total chlorine remaining in chlorinated water that is not bound in chloramines and will react chemically with undesirable or pathogenic organisms.

(o) "Heterotrophic Plate Count (HPC)" means a laboratory test for culturing and quantifying primary indicators of disinfection efficiency and for determining compliance with drinking water standards. Indicators of health risk include normal skin flora such as Streptococcus, Staphylococcus, and Pseudomonas that are likely to be shed in oils, saliva and mucus discharges.

(p) "Hypochlorite" means a family of chemical compounds such as calcium hypochlorite, lithium hypochlorite, sodium hypochlorite, used as a chlorine carrier in public bathing facility water.

(q) "Milligrams per liter (mg/L)", means a unit of concentration indicating the number of milligrams of a substance in a liter of liquid, and which is the equivalent of parts per million (ppm).

(r) "Natural bathing place" means a bathing place that depends on natural flow or upon temperature, wind and wave action for circulation of water. This term includes oceans, lakes, rivers and tidal waters.

(s) "pH" means the relative acidity or basicity of a substance, such as water, as indicated by the hydrogen ion concentration and pH is expressed as a number on the scale of 0 to 14, 0 being most acidic, 7 being neutral and 14 being most basic.

(t) "Pressure-type sand filter" means a filter that uses sand or sand and gravel as the filtering medium, through which pool water is pumped under pressure.

(u) "Pseudomonas aeruginosa" means a bacteria relatively resistant to chlorine and bromine occasionally pathogenic or disease causing in man, responsible for hospital infections that are very difficult to treat because of the bacteria's resistance to antibiotic therapy.

(v) "Public bathing facility" means a swimming pool, spa or special recreation pool operated for any municipality, governmental subdivision, public or private corporation, partnership, association or educational institution open to the public, members or students, whether on a fee or free basis, together with buildings and equipment. This includes, but is not limited to, town public bathing facilities, public bathing facilities at hotels, motels, health facilities, water parks, condominium complexes, apartment complexes and public campgrounds.

(w) "Public bathing place" means a public bathing facility or natural or semi-natural bathing place, operated for any municipality, governmental subdivision, public or private corporation, partnership, association or educational institution open to the public, members or students, whether on a fee or free basis, together with buildings and equipment. This includes, but is not limited to town public bathing places, public bathing places at hotels, motels, health facilities, water parks, condominium complexes, apartment complexes and public campgrounds.

(x) "Semi-natural bathing place" means a pool formed by damming up all or portions of surface waters. Such pools depend upon the flow of surface water for circulation and can have a natural or artificial bottom.

(y) "Skimmer" means a mechanical device connected to the recirculation piping for continuous removal of surface water and floating debris from a public bathing facility.

(z) "Spa" means a body of water, sometimes called a hot tub or jacuzzi, that is designed for recreational and therapeutic use and for physiological and psychological relaxation. These facilities are not drained and refilled after each use; the water is circulated, filtered and sanitized. Spas include hydrojet circulation, hot water, cold water, mineral baths and air induction systems and are not for swimming or diving.

(aa) "Special recreation pool" means a body of water which is not intended for swimming or diving but used typically for receiving bathers at the end of long slides or chutes or for artificial surfing and similar use.

(ab) "Swimming pool" means a body of water that is entirely artificial in construction and has the pool water circulated through it by mechanical pumps and clarified by filtration before being returned to the pool, and is either indoor, outdoor, or both.

(ac) "Total chlorine" means the sum of both free residual chlorine and chloramines.

(ad) "Total coliform bacteria" means a group of bacteria defined as gram negative, aerobic or facultatively anaerobic, nonspore-forming rods that ferment lactose in 48 hours at 95 F (35 C) with gas production by the most probable number (MPN) methodology. Total coliforms are used to measure the quality of potable water, shellfish harvesting waters and to determine the quality of recreational waters because finding coliforms in these waters is interpreted as a degradation of the quality of the water, and therefore a potential health hazard to users or to consumers.

(ae) "Wading pool" means an artificially constructed body of water that has a maximum depth of 2 feet.
