Waters in this classification are a source of raw water supply for drinking and food processing purposes. The water treatment process shall be approved by the Mississippi State Department of Health. The raw water supply shall be such that after the approved treatment process, it will satisfy the regulations established pursuant to Section 1412 of the Public Health Service Act as amended by the Safe Drinking Water Act ( 42 U.S.C. §§ 300f to 300j-27 ). Information regarding surface water intakes for Public Water Supply is provided in Table 3.

Waters that meet the Public Water Supply criteria shall also be suitable for secondary contact recreation. Secondary contact recreation is defined as incidental contact with the water during activities such as wading, fishing, and boating, that are not likely to result in full body immersion. In considering the acceptability of a proposed site for the discharge of wastewater in or near waters with the Public Water Supply Classification, the Permit Board shall consider the relative proximity of the discharge to water supply intakes.
Constituent | Concentration (mg/l) |
Barium | 2.0 |
Fluoride | 2.0 |
Lead | 0.015 |
Nitrate (as N) | 10.0 |
Waters in this classification are for propagation and harvesting shellfish for sale or use as a food product. These waters shall meet the requirements set forth in the latest edition of the National Shellfish Sanitation Program (NSSP) Guide for the Control of Molluscan Shellfish as published by the U.S. Food and Drug Administration. Waters that meet the Shellfish Harvesting criteria shall also be suitable for recreational purposes. In considering the acceptability of a proposed site for the discharge of wastewater in or near waters with this classification, the Permit Board shall consider the relative proximity of the discharge to shellfish harvesting beds.
Waters in this classification are to be suitable for recreational purposes, including such water contact activities as swimming and water skiing. In considering the acceptability of a proposed site for the discharge of wastewater in or near waters with this classification, the Permit Board shall consider the relative proximity of the discharge to areas of actual water contact activity.
For both marine and estuarine coastal recreational waters, enterococci shall not exceed a 90-day geometric mean of 35 per 100 ml, nor shall the samples examined during a 90-day period exceed 130 per 100 ml more than 10% of the time. Coastal recreational waters do not include inland waters upstream of the mouth of a river or a stream having a natural connection to the open sea.
Waters in this classification are intended for fishing and should support protection and propagation of fish, aquatic life, and wildlife. Waters that meet the Fish and Wildlife Criteria shall also be suitable for secondary contact recreation. Secondary contact recreation is defined as incidental contact with the water during activities such as wading, fishing, and boating, that are not likely to result in full body immersion.
For marine and estuarine waters, enterococci shall not exceed a 90-day geometric mean of 35 per 100 ml, nor shall the samples examined during a 90-day period exceed 130 per 100 ml more than 10% of the time.
Waters in this classification are intended to support water quality appropriate for a modified population of fish, aquatic life, and wildlife that are limited or substantially degraded due to alternations of the physical habitat, hydrology, or water quality based on one or more 40 CFR 131.10(g) factors. Waters within this classification share the same water quality criteria as Fish and Wildlife waters with the exception of any modified criteria (narrative or numeric) that have been established for a waterbody or waterbody segment. Waters that meet the Modified Fish and Wildlife criteria shall also be suitable for fish consumption and secondary contact recreation. Waters classified as Modified Fish and Wildlife must also protect the attainment of water quality standards within downstream waters.
Waters within this classification are intended strictly for the drainage of agricultural lands, agricultural irrigation, livestock watering, industrial cooling, or process water supplies. Waters classified as Drainage Waters may contain a transient population of aquatic life when there is suitable habitat for survival of aquatic life. However, typical conditions within these waters are not adequate to support the reproductive cycles for fish and other aquatic life. Waters in this classification can include, but are not limited to, wholly artificial canals or ditches, waterbodies or ditches located behind or influenced by a control structure, or waters which are part of a water control or water management system. One or more of the 40 CFR 131.10(g) factors apply to waters in this class. Waters within this classification share the same water quality criteria as Fish and Wildlife waters with the exception of any modified criteria (narrative or numeric) that have been established for a waterbody or waterbody segment. Waters that meet the Drainage Waters criteria shall also be suitable for fish consumption and secondary contact recreation. Waters classified as Drainage Waters must also protect the attainment of water quality standards within downstream waters.
Waters in this classification are high quality waters that constitute an outstanding Mississippi resource. Waters within this classification can include, but are not limited to, waters within national parks, state parks, wildlife refuges, waters of exceptional ecological significance, or waters of high recreational or aesthetic value. Waters within this classification must meet the same water quality criteria as Fish and Wildlife waters with the exception of any site-specific modified criteria that have been established to protect the outstanding features of the waterbody.
Waters in this classification do not support a fisheries resource and are not usable for human consumption or aquatic life. Ephemeral streams normally are natural watercourses, including natural watercourses that have been modified by channelization or a manmade drainage ditch, that without the contribution of point source discharges, flow only in direct response to precipitation or irrigation return-water discharge in the immediate vicinity and whose channels are normally above the groundwater table. Physical conditions related to the natural features of the waterbody, such as the lack of a proper substrate, cover, flow, depth, pools, riffles, and the like, unrelated to water quality, preclude attainment of aquatic life protection uses. These streams may contain a transient population of aquatic life during the portion of the year when there is suitable habitat for fish survival. Normally, aquatic habitat in these streams is not adequate to support a reproductive cycle for fish and other aquatic life. Wetlands are excluded from this classification.
Waters in this classification shall be protective of wildlife and humans that may come in contact with the waters. Waters contained in ephemeral streams shall also allow maintenance of the standards applicable to all downstream waters.
Recommendations for assignment of the Ephemeral Stream classification shall be made to the Commission on Environmental Quality by the Permit Board after appropriate demonstration of physical and hydrological data. The Ephemeral Stream classification shall not be assigned where environmental circumstances are such that a nuisance or hazardous condition would result or public health is likely to be threatened. Alternate discharge points shall be investigated before the Ephemeral Stream classification is considered.
