WATER QUALITY STANDARDS CRITERIA DIGEST A COMPILATION OF FEDERAL/STATE CRITERIA ON WATER QUALITY SAMPLING AND ANALYTICAL METHODS Ct; -^ ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D.C. ------- WATER QUALITY STANDARDS DIGEST Water Quality Sampling and Analytical Methods and Applicable Stream Flow Provisions This digest was compiled in order to provide general information to the public as well as to Federal, State, and local officials. It quotes those provisions of State/Federal water quality standards which relate to water quality sampling and analytical methods techniques and which stipulate the applicable stream flows. The water quality standards program is directed by the Environmental Protection Agency, an independent regulatory agency which has responsibility for approving State-adopted standards for interstate waters, evaluating ad- herence to the standards, and overseeing enforcement of standards compliance. Standards, the first nationwide strategy for water quality management, contain four major elements: the use (recreation, drinking water, fish and wildlife propagation, industrial, or agricultural) to be made of the inter- state water; criteria to protect those uses; implementation plans (for needed industrial-municipal waste treatment improvements, among others) and enforce- ment plans; and an antidegradation statement to protect existing high quality waters. A majority of the standards establish specific requirements regarding analytical methods. Some standards also expressly include sampling methods. In a minority of standards, provisions are not regulatory but instead merely describe the methods used by the state agency. No provisions for sampling and analytical methods were found in the nine states. The methodology provisions in many standards include authority for the state agency to approve methods other than those set forth in the standards. Where this authority exists, the state agency should be consulted prior to actual sampling and analysis to determine whether distinct practices have been established. In particular, many state standards which were adopted prior to publication of the thirteenth edition of Standards Methods for the Examination of Water and Wastewater (APHA, AWWA, WPCF, 13th Ed., 1971) ex- pressly require that sampling and analysis be conducted pursuant to methods prescribed in the twelfth edition. In these states, the state agency should be consulted to ascertain'whether adherence to the methodology of the thirteenth edition is now required. Finally, the Legal Support Division of the Office of Enforcement and General Counsel, EPA, has published " A Primer on the Law, Evidence, and Management of Federal Water Pollution Control Cases"(EPA, Washington, D.C. 20460, May 1972).Chapter VIII, "Gathering and Preserving Evidence in Water Pollution Enforcement Actions," is enclosed as Appendix A to this summary. It should be recalled that in testing for violations of standards, specific methodology provisions of the applicable standards supersede any other method. Individual State-adopted provisions follow. ------- ALABAMA Water Quality Criteria adopted May 5, 1967, Section III - GENERAL CONDITIONS APPLICABLE TO ALL WATER QUALITY CRITERIA. 2.

CONNECTICUT Water Quality Standards. June 28, 1967; 1968; November 11, 1969; 1970 (No provisions regarding sampling and analytical methods.) Flow (Implementation Plan ) In order to be able to certify the accomplishment of this enforcement program the Commission will occupy and sample water quality at all the sampling stations shown on the watershed maps. The program contemplates the sampling at each of these points at least five times per year during the types of flow which are more critical for the assessment of the individual water quality parameters in that particular stream. These samples will be adjusted by com- putations to a common denominator of flow frequency so that they will be com- parable one to another and from year to year. Traditionally, the Commission has used the flow which occurs at least 85% of the time because of certain hydrologic considerations in Connecticut. Once the parameters have been established on a common flow condition, a uniform method will be developed to interpret quality data in terms of the percent occurrence flow to which stan- dards should apply. COLORADO Water Pollution Control Commission, Terms and Definitions, June 10, 1969. ------- 17. STANDARD METHODS FOR THE EXAMINATION OF WATER AND WASTE WATER. LATEST EDITION. - A publication prepared jointly by the American Public Health Association, American Water Works Association, and the Water Pollution Control Federaltion, accepted by Federal, State, and local authorities in the field of water pollution control as the authority for analytical procedures to be utilized in the examination or analysis of waters and waste waters. Water Quality Standards for Colorado, Adopted May 15, 1968. For purposes of enforcement of these standards, sampling will be done at a point where these standards can be evaluated. For purposes of enforcement of water classification standards, sampling of the waters will be done at any point, except for areas immediately adjacent to outfalls and except as may be noted in the text of the standards. In such areas, cognizance will be given to the opportunity for admixture of waste effluents with receiving water. Tests or analytical procedures to determine compliance with standards will insofar as practicable and applicable, be made in accordance with the methods given in the latest edition of "Standard Methods For The Examination of Water And Waste Water" published by the American Public Health Association, or in accordance with tests or analytical procedures that have been found to be equal or more applicable and satisfactory and accepted and approved by the Commission. Flow No specification. The 1966 Colorado Water Pollution Control Act, as amended (1967) requires the Water Pollution Control Commission, in adopting standards, to consider among other things (section 8(2)(e)),"Whether a standard that is to be applicable to discharges into flowing water should be written in such a way that the degree of pollution tolerated or treatment required will be dependent upon the volume of flow of the receiving water or the extent to which the discharge is diluted therein." DELAWARE Water Quality Standards for Interstate Streams. June, 1967. General. 3. Reservations. Maintenance of stream quality criteria is dependent upon the following conditions. b. The standards proposed are based upon the ability of the Commission to measure and to determine compliance. All measurements will be made at selected sampling stations. Such stations will be selected after determining "representativeness" of the sample obtained and the nature of the mixing at the station. (No further provisions regarding sampling and analytical methods require- ments .) ------- Flow Design of waste treatment facilities should be based on maintaining an effluent of such character that the Water Quality Indicators meet the specifications as state for individual receiving streams, during a low flow period equivalent to the minimum seven (7) consecutive day low flow recur- ring once every 10 years.

It is recognized, however, that in the cases of discharges which occur beyond the reasonable control of man, such as flood-flows of storm water where practicable man-made facilities or control measures are inadequate to the situation, that situations will result which are not in compliance with standards. These will not be excused, but neither will immediate punitive action be taken for such extreme cases until the Director feels that all reasonable measures have been exhausted to obtain voluntary action on the part of the persons or agency responsible for the discharge or the land or enterprise from which it arose to correct the situation or treat the discharge which led to the discharge of offending material IDAHO Rules and Regulations for Standards of Water Quality for the Interstate Waters of Idaho and Disposal Therein of Sewage and Industrial Wastes, June, 1967. 3.

(a) Introduction; (3) Determination of Compliance. In making tests or analyses of the interstate waters of the state, sewage, industrial wastes or other wastes to determine compliance with the standards, samples shall be collected in such manner and place, and of such type, number and frequency as may be considered satisfactory by the Agency from the view- point of adequately reflecting the condition of the interstate waters, the composition of the effluents, and the effects of the pollutants upon the specified uses. Reasonable allowance will be made for dilution of the effluents in relation to the uses of the interstate waters into which they are discharged or other interstate waters which may be affected. The samples shall be preserved and analysed in accordance with the procedures given in the 1965 edition of Standard Methods for the Examination of Water and Waste Water, by the American Public Health Association, American Water Works Association, and the Water Pollution Control Federation, and any revisions or amendments thereto, or other methods acceptable to the Agency.

(I)f at the applicable stream flows mentioned in the sections on specific standards of interstate water quality and purity it is evident that the specified stream flow may be less than the effluent flow, the specific standards may be interpreted as effluent standards for control purposes, where applicable. The period of record for determining the specific flow for the stated recurrence interval, where records are available, will include at least the most recent 10 years of record, including flow records obtained after establishment of flow regulation devices, if any. Such calculations will not be applied to lakes and their embayments which have no comparable flow recurrence interval"!

The Water Quality Criteria contained in these standards are applicable at flows equal to or greater than the lowest flow for seven consecutive days which can be expected to occur at a frequency of once every ten years. For design purposes, this flow may be determined by any accepted statistical procedure using published stream flow data such as Gumbel's method of logarithmic extremal probability using low mean discharge data from the Missouri Basin Inter-Agency Committee studies. The drought flow at any point along a stream may be determined by relating the drought flows at gaging stations and their drainage to the drainage above the point of interest on the stream. "Water Quality Criteria for Intermittent Waters shall apply:" (1) Whenever the waste source is discharging into waters with a record of periodic zero flows 7 consecutive days of a once in 10-vear low flow, (2) Whenever the de- sign flow of the waste source is greater than the design drought flow 7 con- secutive days of a once in 10-year low flow, (3) Whenever the actual flow of the receiving waters is less than the waste source discharge.

It should be noted that the standards are stream standards and not effluent standards, as samples taken for the regulation and enforcement of these standards are to be collected at the mid-point of the stream flow at locations ef sufficient distance downstream from the point of introduction of a waste-water inflow to provide for reasonable mixing of the stream and the in- flowing water. Where stratification exists, other sampling techniques may be employed. Sampling in reservoirs and lakes for the purposes of the standards may be at any point in the body of the water, but not closer than 250 feet from the point of introduction of a water contaminant. A reservoir or lake is considered to include all of the area flooded when the water in the basin is at the spillway level. General Standards. ?• 7. Toxic Substances. . . . Toxicities of substances in receiving waters will be determined by appropriate bio-assaytechniques, or other acceptable means, for the particular form of aquatic life which is to be preserved. Flow (Criteria; set for individual basins.) Pecos River. General Standards. The following general standards shall apply to the waters of the main stem of the Pecos River in New Mexico regardless of the magnitude of flow. . . . Special Standards. The flow in the Pecos River and the uses of the waters of the river vary considerably from one section to the next. Because of these variations, two sets of special standards are proposed to protect the waters of the river for both existing and potential future uses. . . A. For the main stem of the Pecos River from Anton Chico, New Mexico to the head waters at all flows. . . . Special Standards for Chlorides, Sul fates, and Total Dis- *Mi Hi grams per Li ter . ------- solved Solids. (Main stem, Pecos River) ... At very low flows, the concentration of some of the chemical constituents is quite high and quite variable, but these flows represent a relatively small part of the total water supply of the river. Because of its hydrologic nature and because of the regulations of the flows of the Pecos River by dams and reservoirs, the experience at many points on the river is that either relatively high flows exist or that there is virtually no flow in the stream. To allow for these low flow periods, and to protect the quality of the stream at high flows, the standards for chlorides, sulfates and total dissolved solids have been formulated in terms of mathematical relationships between flow and the concentration of the particular constituent. Special standards for this purpose apply only to samples collected at the station indicated and for periods during which the flow in the stream is within the range used to establish the relationship.

Water Quality Standards Surveillance Plan for Drainage Basinsin Oregon; General Surveillance. The present state 6'f Oregon's water quality surveillance program involves periodic checking of fixed stations that are selected as monitoring or control points above and below pollution sources or near the mouths of streams. As these points it is usual to run a sanitary survey consisting of date, time, flow, pH, temperature, dissolved oxygen (DO), biochemical oxygen demand (BOD), Perle Benson Index (PBI), specific conductance, most probable number of coliforms (MPN), and any other parameter that appears to be pertinent to the particular area or condition. In many cases waste treatment samples, domestic, municipal, agricultural or industrial, are analyzed jointly with the sanitary survey to coordinate cause and effect relationships. In addition to the sanitary survey, basic data are run at strategic locations. For these points laboratory analysesare performed including pH, color, turbidity, total solids, suspended solids, alkalinity, hardness, sulfates, ammonia nitrogen, nitrate- nitrogen, phosphates, and chlorides. Wherever other chemicals or problems are suspected, special analyses are made to characterize these conditions. All testing is in accordance with Standard Method'**. Frequency of sampling varies from daily to yearly depending on needs for the data. Each of the stations is identified by code numbers, river mile *Mi Hi grams per Liter. 19 ------- and other identifying features so that samples are taken at the same point each time. . . **Standard Methods for Analysis of Water and Wastewater, 12th Edition, APHA, AWWA and WPCF, 1962.

Much more work is needed before acceptable minimal stream flows can be set. The main needs are for travel times and physical characteristics of the streams to determine reoxygenation coefficients and for tests to determine deoxygenation rates. PENNSYLVANIA Water Quality Standards for Pennsylvania's Interstate Streams, June, 1967. Section V, Implimentation Plan, Part II. I. Sarveillance Program. Stream Monitoring. We believe that the stream monitoring program related to water quality standards enforcement should be carried out by an intensive low flow sampling program. Such low flow sampling would be conducted in the criti- cal reaches of streams. We believe that this type of sampling will enable us to determine if the water quality criteria are being met and better relate waste treatment requirements of water qualtity criteria. (No provisions regarding analytical methods.) Flow (Implementation) D. Design Flow, The implementation plan has been designed using a criteria or design stream flow equivalent to the minimum seven consecutive day flow that occurs one time in ten years. Treatment plants designed to meet the criteria at the critical flow conditions are to be operated at that design efficiency at all times. This will result in water quality ex- ceeding the criteria most of the time. 20 ------- Part II, Surveillance Program, (b) Stream Monitoring.

UTAH Water Quality Standards and Implementation Plan for Interstate Water. June, 1967. Implementation and Enforcement Plan. Surveillance. Sampling and analytical techniques. Samples for MPN coliforms and for BOD analyses are collected in appropriate containers and are packed in ice from time of collection until delivery to the laboratory. Delay in route for these samples is seldom in excess of 24 hours. Sam- ples for chemical and radiological analyses are collected in appropriate containers and are also delivered to the laboratory on a rapid schedule. All analyses of interstate water samples, except radiologic analyses, are carried out by the Utah State Department of Health Division of Laboratories in accordance with "Standard Methods for the Examination, of Water and Wastewater - Twelfth Edition 1956" as published by the American Public Health Association, Inc. Radiologic analyses are conducted by the radiological health laboratory within the Division of Environmental Health. Flow (Criteria.) Specific Standards Assigned to Interstate Waters. Stream flow and sampling considerations. Although not covered explicitly by the standards, it is clearly implied that the quality requirements relate to all uses and must apply, therefore, to all flows. At the same time, anyone know- ledgeable in matters of water quality control will realize that a given set of standards can be made unachievable if the normal wide fluctuation in stream stages is not recognized. For this reason standards have been related to minimum monthly-average flows in specific situations where permits are being considered. The complexities of stream patterns argue for the development of more information before flows are tied precisely to quality parameters. Nevertheless, as presently constituted and applied, standards require minimum practicable treatment for any situation, including a dry stream channel, by reason of the requirement that any effluent release from a controlled area must meet certain bacterial and B.O.D. standards (See following discussion under "Effluent Standards"). 24 ------- Effluent standards (mimimum practicable treatment . While the stand- ards described apply generally to receiving stream flow, they can and must become effluent standards as required by lack of dilution water. . . . VERMONT Implementation Plan, Vermont Water Resources Board, June, 1967. Surveillance In general, sampling and analyses are done in accordance with Standard Methods. . . Stream sampling is done on a "grab" sample basis except where time and space of the pollution distribution is questionable and should be considered. Flow Implementation Plan, June 1967. Surveillance. . . . Stahdards shall apply to stream conditions existing during criterical minimum low flow periods. On many streams the critical flow does not have the usual frequency of occurrence that can be assigned on a hydroloqic basis, but rather the flow is regulated by the operation of hydroelectric stations. The usual summer or low flow operation is released during the peak electric use time and stored during the remainder; this becomes critical on summer week- ends. On streams where regulation is not a problem,the low seven-day average flow with a return period once in ten years will be used.

The laboratory applies methods of analysis that are in the current edition of Standard Methods for the Examination of Water and Wastewater. The State Water Quality Network. The Division of Water Resources will collect river samples at the locations listed as stream monitoring stations. Sample collectors will be employed and trained to properly collect, and bring to the central laboratory, water samples from the monitoring stations. Bacterial samples (coliform) will be collected at station site in 4 oz. pre-sterilized sample bottles. The sterilizing will be done at the central laboratory. Bacteria bottles will be subjected to twenty pounds pressure, 248° F for fifteen minutes. Coliform samples will either be brought or bussed to the central laboratory so that not more than 24 hours time will have elapsed from collection to the beginning of the analysis. In addition to coliform, the Division of Water Resources will monitor fecal streptococcus and fecal coliform at all station sites. Water samples for mineral and other chemical determinations will be collected at sample location in properly clean polyethylene containers. Samples that require the addition of preservation will be collected in separate containers. Temperature will be made in the field at station location; thermo- meter will be Fahrenheit scale and will be checked and corrected against a Bureau of Standards thermometer kept in the central laboratory. Dissolved oxygen tests will be collected and fixed in the field at station sites. River Samples will be made at a point judged by samples to be repre- sentative of stream flow. The only exception to this criteria will be on the Kanawha River where presently mass discharge points are located at each bridge sample station. Flow (Criteria; set for individual basins.)
