For the purpose of this article and this chapter generally, the following terms shall have these meanings:
AQUIFERA saturated and permeable geologic formation that can yield significant quantities of water to wells, springs, or surface water bodies.
BEDROCKThe solid rock, commonly called "ledge," that forms the earth's crust.
COMMUNITY WATER SYSTEMA public water system which serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents.
CONTAMINANTAny physical, chemical, biological, or radiological substance or matter in water which impairs its intended or feasible use.
DEGRADATIONA deterioration or a decline in ambient water quality.
DISCHARGE TO GROUNDWATERThe intentional, negligent, accidental, or other release of any pollutant onto or beneath the land surface, in a location where it is likely to enter the groundwater of the state.
DISPOSALThe deposit, injection, dumping, spilling, leaking, incineration of, or placing of any pollutant or hazardous materials into or on any land or water so that such pollutant(s), hazardous material(s) or any constituent thereof may enter the environment.
GA CLASSIFICATIONGroundwater classified GA are groundwater resources, which, like GAA, are known or presumed to be suitable for drinking water use without treatment. However, groundwater classified GA does not fall within any of the priority areas described under GAA.
GAA CLASSIFICATIONGroundwater classified GAA includes those groundwater resources that are known or presumed to be suitable for drinking water use without treatment, including the following:
A. The state's major stratified drift aquifers that are capable of serving as a significant source for a public water supply (groundwater reservoirs) and the critical portion of their recharge areas as delineated by DEM; and
B. The wellhead protection area for each public water system community water supply well. Community water supply wells are those that serve resident populations and have at least 15 service connections or serve at least 25 individuals (e.g., municipal wells, and wells serving nursing homes, condominiums, mobile home parks, etc.).
GROUNDWATERWater found underground which completely fills the open spaces between particles of sand, gravel, clay, silt, and consolidated rock fractures. The zone of materials filled with groundwater is called the "zone of saturation."
GROUNDWATER RECHARGEThe process of the addition of water to the zone of saturation, that zone beneath the water table.
HAZARDOUS MATERIALAny material defined as a "hazardous substance" by Section 101(14) of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980 (42 U.S.C. § 9605), as amended. Hazardous material shall include any hazardous waste as well as any of the following materials: acetone, ethanol, ethylene oxide, methanol, methylene chloride, perchloroethylene and petroleum products. The enumeration of the above materials is not intended in any way to minimize the list of material defined in the aforesaid section.
HAZARDOUS WASTEAny material or combination of materials of a solid, liquid, contained gaseous, or semi-solid form which because of its quantity, concentration or physical, chemical, or infectious characteristics may:
A. Cause or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness; or
B. Pose a substantial present or potential hazard to human health or the environment. Such materials include, but are not limited to, those which are toxic, corrosive, flammable, irritants, strong sensitizers, substances which are assimilated or concentrated in and are detrimental to tissue, or which generate pressure through decomposition or chemical reaction and include septic wastes. In addition, such materials include "industrial waste" as such term is used in the Rhode Island General Laws, as amended, unless the context shall clearly indicate otherwise. Hazardous waste shall also include all waste types as defined in the rules and regulations adopted in accordance with Title 23, Chapter 19.2 of the General Laws of the State of Rhode Island, and Providence Plantations, as amended.
HAZARDOUS WASTE MANAGEMENT FACILITYA facility, excluding vehicles, for collection, source separation, storage, processing, treatment, recovery, or disposal of hazardous stations for hazardous waste, and may include a facility at which such activities occur, and hazardous waste has been generated.
MAXIMUM CONTAMINANT LEVELThe maximum permissible level of a contaminant present in the water determined at a point of entry into the distribution system and at any point in the distribution system.
POLLUTANTA man-made or man-induced substance which causes or could cause the alteration of the chemical, physical, biological, or radiological integrity of groundwater.
RECHARGE AREA OF AQUIFERAny area in which precipitation percolates to the water table and flows through materials to the aquifer.
RESERVOIRA pond, lake, or basin, either natural or artificial, for the storage, regulation, and control of water.
SOLID WASTESUseless, unwanted, or discarded solid materials with insufficient liquid content to be free-flowing. This includes, but is not limited to, rubbish, combustion residues, garbage, scrap materials, junk, fill material, demolition debris, construction waste and refuse.
UNDERGROUND STORAGE TANK (UST)Any one or more combinations of tanks (including underground pipes connected thereto) used to contain petroleum or other hazardous material and which is located wholly or partly beneath the surface of the ground.
WATER SUPPLY OVERLAY DISTRICTThe Water Supply Protection Overlay District includes all land in the Town identified as major stratified drift aquifers and their recharge areas (GAA Classification), surface drinking water supply watersheds, community wellhead protection areas, and Town-owned non-transient, noncommunity wellhead protection areas (schools). The term "Water Supply Protection Overlay District" shall be synonymous with "Groundwater Aquifer Protection Overlay District."
WATER SUPPLY WATERSHEDThe portion of land drained by a river and its tributaries to a reservoir used for the storage, regulation, and control of public drinking water.
WATER TABLEThe upper surface of the saturated zone in an unconfined aquifer.
WELLHEAD PROTECTION AREAThe critical portion of a three-dimensional zone, surrounding a community public well or Town-owned non-transient noncommunity well (schools) through which water will move toward and reach such a well or well field as designated by the RIDEM and any amendments thereto.
