    PROCESS DESCRIPTIONThis section gives a desciption of each process used in our design.

    Each block used in the flowsheet is descibed below. The blocks are listed inthe same order the wastewater stream would flow through in the plant.HoldingBasin I (llB1)

    After passing through a grit-removal screen, the wastewater streamenters a holding tank. This tank is for adjustment of the stream pH to 8 (byaddition of Hme), which is necessary for the mercury removal process. Thetank is designed for a 30 min residence time.C1ariCone Mercury Removal Clarifier (C-MR)

    The ClariCone unit is designed to remove the mercury from thestream with sulfide precipitation. A unit that would handle our mercuryconcentrations was suggested by CBI Walker, Inc. See Appendix 1 for theactual information CBI Walker sent.Mercury-Removal Waste StorageTank (MST)

    The slurry waste from the ClariCone is collected in a tank, whichwill be removed every month by Chemical Waste Management. The tank isdesigned to hold a blowdown of 250 gal of slurry every 6 hr.HoldingBasin2 am2)

    The second holding tank is used to hold the wastewater stream whilea carbon bed is being changed. It is designed to hold 8 hr of flow.HoldingBasin 8 (HB3)

    The third holding tank adjusts the stream pH to 5 (with HC!) for thecarbon beds. It is designed for a 30 min residence time, the same as HB1.Activated CarbonBed I (CBI)

    The first carbon bed is used for PCB adsorption. It was designed byCalgon Corporation. Chemical Waste Management will remove the spentcarbon from this bed and Calgon will replace it with fresh carbon every sixmonths.

    PROCESS DESCRIPTIONActivated Carbon Beds 2& 3 (CB2,3)

    The second and third carbon beds are used for adsorption of TCE,TCA and organic carbon. They were designed by Calgon, and Calgon willreplace their carbon every two months.Holding Basin 4 (HB4)

    The last holding tank collects 8 hr of clean water for adjustmentbefore release into the river. If necessary, the water is adjusted fortemperature, oxygen, and pH (6-7) in this tank.

    MAJOR EQUIPMENT SIZINGThis section gives the sizes of the major equipment used. The calculationsused to find these sizes are given in Appendix 2.HoldingBasin 1 (BBl)

    The first holding basin is designed to hold the maximum flowrate,300 gpm, for 30 min. It is a cubic tank with volume of 13500 gal and 12.25-itsides.CIariConeMercury Removal Clarifier (CMR)

    The ClariCone was sized by CBI Walker to meet our mercuryremoval needs. The size they selected has a top diameter of 26' and a heightof 20'4". This size is called "Unit Size 3ft by CBI Walker. See Appendix 1 fora schematic of the ClariCone supplied by CBI Walker.Mercury-Removal Waste StorageTank (MSI')

    From information by CBI Walker, the ClariCone win have a 250-galblowdown every 6 hr for our flowrate and mercury concentration. The MSTwas designed to hold 30 days of this waste. It s volume is 50000 gal.HoldingBasin 2 aIB2)When a carbon bed is being replaced, the waste stream is divertedinto HB2. It is sized to hold 300 gpm for 8 hr. With these specifications, a144000 gal cubic tank with 27 -it sides was chosen.Holding Basin 3 (HB3)

    The third holding tank holds the waste stream before entering thecarbon beds and adjusts its pH to 5 before entering the carbon beds. It issized to have a retention time of 30 min for a flow rate of 300 gpm, and winthen be the same size as HB1, 13500 gal.

    MAJOR EQUIPMENT SIZINGActivated CarbonBeds 1-3 (CHI-3)

    The carbon beds that Calgon recommended to us are sized to handle350 gpm of wastewater with our pollutant concentrations. Their carbonbeds have a diameter of 10', a volume of 715 cu.ft, and a height of about 20'.See Appendix 1 for the sizing and other information provided by Calgon.Holding Basin 4 (HB4)

    The final holding tank holds clean water for 8 hr before release intothe river. This tank is designed to be the same size as HB2; a 144000 galcubic tank.Pipe

    The pipe diameter was suggested by Perry's to be 6" for a 300 gpmflow. Schedule 40 pipe was chosen.Pumps (p1IO)

    The ten pumps used in the design are all sized to pump a maximumof 300 gpm through 6" i l l pipe with a head of 15-25 ft. The pump type thatsatisfies these requirements is a centrifugal, one-stage, 1750 rpm, VSC,stainless steel pump.

    EXPLANATION OF COST ESTIMATESIn this section, a brief explanation for our costs is given.PurchasedEquipment Costs

    The equipment (HB 1-4, CB 1-3, P 1-10, CM-R) costed are shown onthe enclosed flowsheet. The equipment were sized, and then priced withthe Walas textbook, Chemical Process EQuipment Selection and Desilln,except for the carbon beds, which were priced directly from themanufacturer. These prices were then converted to 1992 dollars.

    OtherFixed Capital Investment CostsThe fixed capital costs were estimated as a percentage (shown on thecost estimate sheet) of either the purchased equipment cost, the direct cost,or the total fixed capital investment. The percentages were obtained fromthe Peters and Timmerhaus textbook, Plant Desim and Economics forChemical Enlrineers, Table 26, p. 210. The land cost was based on fouracres at $75,000/acre. The total fixed capital investment was estimated at$3,693,750, which includes a working capital of $738,750.

    OperatingCostsThe operating costs, unless otherwise explained, were calculated as

    a percentage of the fixed capital investment. The percentages were alsoobtained from Peters and Timmerhaus. The chemicals were costed withthe journal Chemical Marketinll Reporter. The depreciation wascalculated as (FC! - 0.1 FCI)/(15 yr). The carbon costs were obtaineddirectly from the manufacturer. The total operating cost was estimated at$1,154,450/yr.

    See Appendix 3 for costing calculations, and Appendix 1 for manufacturerinformation on costing.

    STATE-OF-THE-ART TECHNOLOGYThe ClariCone is an upflow solids contact processwhich combines mixing, tapered flocculation and clarification in a completely hydraulic-driven vessel.A rotating slurry blanket is maintained in suspensionby proper control of hydraulic energy. The raw watermust pass through this blanket prior to its dischargefrom the unit. The expanding helical flow patternaccelerates floc formation by providing intimate contactbetween previously flocculated particles in the blanketand the coagulated material in the raw water.The mixing zone is formed by a cylindrical section.The tangentially oriented inlet nozzles in combinationwith the cylindrical shape, direct the flow into thehelical pattern necessary to provide f f e c ~ i v e treatmentwithout short circuiting.Adjustable velocity control is provided by the tangential inlet nozzles. By proper control of the hydraulicflow vectors, the rotating blanket is maintained in suspension without allowing floc particles to escape intothe clarification zone.The solids contact zone in the conical area continuesthe helical flow pattern established beneath it. Theconical shape provides for a decrease in energy andvertical flow rate as flow progresses upward intothe cone.As a result, ideal tapered flocculation occurs withthorough mixing and gentle flocculation providing flocgrowth. The extremely long helical flow path, fromthe bottom through the blanket, has proven to behighly effective, and conventional retention timesare unnecessary.The slurry concentrator is the heart of the ClariConeprocess. The concentrator is centrally located to takeadvantage of the floc movement toward the quiescentcenter of the vessel. It is vertically adjustable to allowfor changing the blanket depth or solids contact tjme.to adjust the slurry removal point within the blanket

    to maximize slurry concentration, and to permitvisual control.Solids are removed from the rotating blanket by oveflowing into the concentrator, and are thickened withthe conical shape by compaction. Solids blowdownis accomplished through the vertical downcomer bya timer controlled valve.The clarification zone produces settling dynamicssimilar to those found in an ideal settling basin. Duto the helical flow, the horizontal flow vector is largeand the vertical flow is small, simulating long horizontal flow basins. This provides an extended distance of several hundred feet in the ClanCone inwhich floc particles can settle. Short circuiting, founin vertical flow basins with flow distances of only teto fifteen feet from slurry level to the weir, is elimimatin the ClariCone.

    New Treatment Plant for Drain and Run-off WaterThe company has recent ly been c i ted by the s ta te EPA fordischarging several pol lutants from the northwest port ion of ourmanufacturing complex in to the Goodtaste River . At the presentt ime, a l l f loor dra ins from Buildings A and B discharge in to adrainage di tch t ha t runs along the south of both Building A andBuilding B as shown in Figure 1. Since we or ig ina l ly did notexpect any s ign i f i can t pol lutants in the bui ld ings , th i s 'water iscarr ied in an open rock l ined t rench into the r ive r . This t renchpath also receives the near surface flow and surface (storm)water from th is area . The f loor dra ins are del ivered to thet rench by underground pipes , an d cur Environmental ServicesDepartment has been able to monitor the low in each drain pipeas well as the t o t a l t rench flow a t d i f fe ren t points along i t slength .

    These are average flow ra tes and not instantaneous ra tes . Boththe f loor drains and the storm drains vary cons iderably , but thef loor drain flow over any 24 hour period is essen t ia l ly the sameas the average flow ra te . However, th e storm dra in ra te dependsgreat ly upon the weather condi t ions . The highes t ra te a t thedischarge of the t rench repor ted by Environmental Services was500 gpm, but tha t is believed to be near the capaci ty of thet rench . I f the r a in f a l l is grea ter , much of the addi t ional flow1s believed to flow di rec t ly to the r iver , not through the t renchsystem.The state has agreed to accept our promise to build a treatmentfac i l i ty that will be capable of handling storm drain ra tes up to

    Na or Mn. Slurry discharge will be collected andremoved every month by Chemical WasteManagement.

    Method of Organics Removal: Activated carbon bedsfrom Calgon Carbon Corporation. Three beds willbe used. The first bed Is used for PCB removal, andits spent carbon will be removed by ChemicalWaste Management and replaced by Calgon everysix months. The other two beds are used for TCE,TCA, and other organic carbon removal, and eachbed will be removed and replaced by Calgon everyother month. The wastewater will be tested by GCto determine if the carbon needs to be replacedearlier than these times.

    the Sixth amendments. One author asks, "At what point does anaccused person's right to a fair, 'speedy and public trial,' protected bythe Sixth Amendment supersede the right of the American public,and the press as the public's representatives, to be fully informedunder the guarantees of the First Amendment?" 2

    Specifically, the question is twofold: what information does thepaper publish and when does it publish it? 3 One study found 98percent of papers will publish the person's name and the charge he ISfaced with. 4 From there, in order of increasing reluctance to publishare: details of arrest (13 percent withheld the information); criminalrecord (50 percent withheld); statements by the accused (64percent); witness testimony (65 percent); and guilty plea bargaining(74 percent). After the newspaper has decided what to publish, itmust also decide if it will release the information before, during orafter th e trial.

    Another important type of information is confessions made bythe accused. In the case of Rideau v. Louisiana (which will be morefully discussed later in the paper), the defendant was interrogated oncamera by the sheriff, and he confessed to bank robbery, kidnappingand murder. The interrogation subsequently aired on local TV,causing Rideau's attorneys to claim their client's right to a fair trialwas jeopardized. Newspapers must weigh the effects of publicizingsuch confessions, for they are particularly likely to prejudice thepublic.

    It should be noted that the free press/ fair trial issue involvestwo communities, and one is partial to a free press while the other isconcerned primarily with a fair trial. 5 From the journalist's point of

    2

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    66/82

    View, a free press is a vital part of society, and rarely (i f ever) shouldthis right to print be abrogated. Of course, a free press is alsoimportant to lawyers and judges, just as reporters value a fair trial;but each community has its soap box, and feels "their" amendment ismore crucial.

    Journalists can claim a long history of press freedom in thiscountry. Those who shaped the Constitution and its underlyingvalues held to the Miltonian principle that all ideas should beallowed to enter the public forum. Various cases through legalhistory have again and again supported the right of the press (andby implication, other media) to print without fear of prior restraintor punishment. As Donald M. Gillmor, author of Free Press and FairTrial, notes: "Freedom of speech and press as social rights are thekeystone of an open society, the freedoms that best guaranteeagainst the destruction of all other rights." 6

    There are at least three reasons why the journalist believeswhat goes on in the courtroom should be information to which theyhave access. First, the reporter usually affirms the concept of anygovernment or official proceeding as being pUblic. To further thisidea, journalists and their interest groups have supported "sunshinelaws." These regulations require such "official" meetings to be open,whether to the press or the public in general. In the same vein, thefederal Freedom of Information Act has also allowed journalistsaccess to government documents.

    Second, one nlay say that journalists often feel they are on analtruistic mission to serve the public. They often speak of thepublic's "right to know" certain kinds of information. 7 Since society

    3

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    67/82

    is so large and diversified, it would be impossible for every citizen toattend every sort of government function. Thus, the press must bethe public's eyes and ears to maintain a well-informed populace.With such a responsibility on its shoulders, the press affirms its rightof access to courtroom proceedings.

    A third reason is perhaps less noble. Very often, the publicloves to hear the details of sensational crimes and theiraccompanying trials, and the newspapers realize covering such trialsis good for business. One only has to look at the recent rash ofsensationalized trials, from Noriega to Dahmer to Kennedy-Smith toTyson, to see this phenomenon. The public has an interest in suchtrials in particular (as to why, this writer will not speculate), andnewspaper coverage can generate reader interest. In a time ofincreased media competition, this can be vital to newspapers,although some editors may wish it were otherwise.

    The legal community, on the other hand, sees achieving justicethrough a fair and speedy system of trial and appeals courts as theirprimary concern. They too can claim a long history of striving fortheir noble cause. Gillmor notes that when the colonists came to thiscountry, they brought with them the concept or trial by jury. Hewrites: "The Sixth Amendment guarantees to all persons accused of acrime a trial by an impartial jury, which, by implication, reaches itsverdict solely upon the facts submitted to it by the court." 8 In otherwords, the United States has always been committed (at least intheory) to the concept of a fair trial.

    Lawyers and judges, in their concern for the rights of theindividual, have instituted several safeguards to ensure that the jury

    4

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    68/82

    will not be biased. 9 Prior convictions are not told to the jury. Thejurors are instructed not to discuss the case among themselves. Thedefendant has the right not to incriminate himself. Hearsay is notpermitted in the courtroom, and only those who touched orparticipated in the events are allowed to function as witnesses. Suchprovisions as these assure, at least to some degree, that the jury ofone's peers before which one is tried will not make its decision basedon anything but the facts of the case.

    Those in the legal profession feel the weight of responsibility tothe public in the same way as journalists. Their responsibility,however, is not the "public's right to know" but rather the"individual's right to justice." The American Bar Association asserts"that the primary burden for ensuring fair trial rests on the legalbranch and the agencies which serve and minister to it," and to someextent "the streams of justice which should be clear are made less soby the news media, whose task it is to keep the people informed." 1 0

    So it is that one must see the issue of fair trial and free press astwo conflicting concepts, each of which is a high value. As SamRagan, a former APME president notes, "the two are not arrayedagainst each other. They are not incompatible, for there cannot be afair trial without a free press." 11 And yet the two, while not alwaysbeing mutually exclusive, do come into conflict many times in actualpractice. The conflict is perhaps inherent in the U.S. Constitution.Herein lies the heart of the matter. When faced with two concepts,both highly valued in society, where does one draw some lines? Asshall be demonstrated, the question poses both legal and ethicaldilemmas for all involved.

    5

    69/82

    The legal aspect of the issue of pretrial publicity involves caselaw for the most part, especially three major cases: Irvin v. Dowd,Rideau v. Louisiana, and Sheppard v. Maxwell. These will bediscussed in turn. A fourth case, Estes v. Texas, will also bementioned because of its significance, but it deals with the issue ofcameras in the courtroom so it will not be given extensive treatment.

    The ABA lists six factors in what may be considered a gooddefinition of pretrial publicity with the ability to cause prejudice. 1 2They are (1) criminal records of the defendant or opinions on hischaracter; (2) a confession by the defendant; (3) the results of anytest (Le., a lie-detector) or the defendant's refusal to take a test; (4)the identity, testimony or credibility of a witness; (5) the possibilityof a guilty plea; and (6) opinions as to guilt or innocence orstatements about the merits of the case or its evidence. The ABAbegan forming such definitions and guidelines in the wake of thesensationalism surrounding the arrest of Lee Harvey Oswald and thecases mentioned above, the first of which was Irvin v. Dowd.

    In 1954 and '55, SIX murders took place near Evansville,Indiana; and in April of 1955 Leslie Irvin was arrested on charges ofburglary and bad check writing. Soon after his arrest, however, thepolice got from him a confession to the murders, and they issued thisinformation to the public in a press release. Calling him "Mad Dog"Irvin, the news media unleashed a torrent of publicity about thecase. Irvin's previous criminal record was published, and he wasdescribed as a "confessed slayer of six." 13

    Irvin's attorney requested a change of venue, and his requestwas granted -- the trial was simply moved to the county next door.

    6

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    70/82

    When voir dire proceedings began, 370 of 430 prospective jurorssaid they believed Irvin was guilty. 14 Irvin, as one might guess, wasconvicted, but he appealed his case all the way to the Supreme Court.The high court overturned the conviction, thus marking the first timethat pretrial publicity was determined to have prevented a fair trialfrom being obtained. 15

    The 1963 case Rideau v. Louisiana was the next step in layingthe legal foundation of prejudicial publicity. This time, televisionwas the culprit, but the principles were the same. Wilbert Rideauwas arrested shortly after a bank was robbed, and while being heldin jai l he was interviewed on camera by the sheriff. The interview,during which Rideau confessed to the crime, was given to a localtelevision station which ran it several times.

    Because many people in the area saw the telecast, theattorneys, as in Irvin, requested a change of venue. The request,however, was denied, and Rideau was convicted. Appealing his caseto the Supreme Court, he was able to have his conviction overturnedon grounds of unfair pretrial publicity. The Court ruled that"prejudice generated in this way (by televising the "interview") byan official is so conclusive that change of venue and continuance oftrial are automatic. No amount of care in jury selection could curethe prejudice." 16

    The third major case in the free press/ fair trial debate isprobably most important. In 1953, Marilyn Sheppard, the pregnantwife of Dr. Sam Sheppard, was found bludgeoned to death in herhome in Cleveland, Ohio. Police immediately suspected Dr. Sheppard,especially after a somewhat inconsistent story of a "bushy-haired"

    7

    72/82

    Each will be discussed in turn, with a brief summary of the relevantcase law.

    One of the most dubious It safeguards It for a fair trial that hasbeen used is the so-called "gag order." During the late 1960s andearly 1970s, judges increasingly began issuing restrictive orderspreventing the news media from releasing to the public informationconsidered "extrajudicial. It Often, the only information consideredpublishable was the most basic facts of the case such as the person'sname, the circumstances of the arrest, the charge against him, etc.As might be expected, this trend was met with alarm fromjournalists, who called it a form of prior restraint. 1 9

    Several case are important here. U.S. v. Dickinson first found ajudge's gag order unconstitutional, but the reporters involved werenevertheless required to pay the fines they had been assessed.However, in the case of Nebraska Press Association v. Stuart, thepress won a big victory. The Supreme Court ruled that because ofthe N ear proscription against prior restraint, gag orders werepresumed to have a heavy weight against them as to theirconstitutionality. In 1984, however, the pendulum swung the otherway somewhat as the Court upheld a gag order in Seattle Times v.Rhinehart.

    A second issue, one quite related, is that of the court'scontempt power. A judge has the power to rule a person (withoutany sort of trial) in contempt if he violates a court order such as a" gag order." 20 This sort of contempt should be differentiated fromanother form of contempt not discussed here, that of a journalist'srefusal to testify or to reveal sources. The contempt resulting from

    9

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    73/82

    disobedience of an order may be civil or criminal, and in the case ofjournalist's violation of a gag order in a criminal trial, the offensewould be a criminal one. A jail term would normally last for thetime the court is in session.

    A third issue concerns the closing of the courtroom to the newsmedia. Obviously, this solution is repugnant to most members of thepress. One author states that "closure of the criminal courtroom is adrastic remedy even in the face of the accused's clear right under theSixth Amendment to a fair and public trial. Closure flies squarely inthe face of the democratic precepts under the First Amendment .. " 2 1While most people might agree that a courtroom should not beclosed, there is more debate over the idea of closing pretrial hearingsthat are not part of the actual trial.

    Two cases are of prime importance here. First, Gannett v.DePasquale determined in 1979 that the press has no right to attendpretrial hearings. The case outraged journalists, who felt that sincemany decisions are made in such hearings, the public has a right toknow about them. Subsequent cases have largely overturned thisruling. A second important case was the 1980 decision in RichmondNewspapers v. Virginia. It was ruled by the Supreme Court that,while the press may not always have the right to cover pretrialhearings, they do have a constitutional right to cover the trialsthemselves. 22

    One can therefore see how various cases over the past fourdecades have shaped the law of the free press! fair trial debate. Thejournalist has won victories in some places and suffered setbacks inothers. Pretrial publicity has been determined to be a definite cause

    10

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    74/82

    at times for unfair trials. Gag orders and contempt rulings have beenused to curb the media, although this is much less true today.Courtrooms are open to reporters, but pretrial hearings may still bequestionable. These methods of trying to balance free press and fairtrial considerations fall into the realm of law. But, the issue mustalso be addressed from the ethical standpoint.

    There is no real agreement among journalists and lawyersabout what is ethically required of each. Of course, both realize theymust do nothing to jeopardize the fairness of the trial orsignificantly compromise the freedom of the press. However, theseare abstract goals, and the question remains of how these ideas areplayed out in concrete terms.

    In the legal community, the so-called Reardon report, adoptedin 1968 by the American Bar Association, is of major importance.Soon after it, a report that came to be called the Kaufman report waspublished in response to Sheppard by the Committee on theOperation of the Jury System, part of the Judicial Conference of theUnited States.23 The two reports are in places identical; but, unlikethe Kaufman report, the Reardon report had some extra provisionsthat warrant study. First, however, will come a brief summary of theareas where the reports are in agreement.

    Concerning attorneys, the Reardon report concluded, "It is theduty of the lawyer not to release or authorize the release ofinformation or opinion ... in connection with pending or imminentcriminal litigation ... if there is a reasonable likelihood that suchdissemination will interfere with a fair trial." 24 Basically, theattorney is being told it is his ethical obligation to reveal absolutely

    11

    http:///reader/full/States.23http:///reader/full/States.23http:///reader/full/States.23
  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    75/82

    nothing to the media that might jeopardize the trial. This conclusionwas reached also for courthouse personnel involved in a potentiallyunfair trial.

    However, whereas the Kaufman report states, "The Committeedoes not presently recommend any direct curb or restraint onpublication by the press of potentially prejudicial material," 25 theReardon report is not so kind. One of the things it recommends is forcourts to adopt a rule giving the defendant the right to make amotion excluding the public, including members of the press, fromany pretrial hearing in a crinlinal case. As has been noted above,this right was upheld in the case of Gannett v. DePasquale, butsubsequent cases have weakened this provision.

    Another scary recommendation in the Reardon report is forquite extensive use of the court's contempt power. Although thereport calls for "considerable caution," it also says the contemptpower should definitely be used in certain circumstances. 26 Thesecircumstances include a reporter's release of any "extrajudicialstatement" beyond what is in the public record or his violation of a"gag order" imposed by the judge. The Reardon report, then, iswilling to lay down some strict ethical guidelines to ensure a fairtrial, and will back up any violations of these ethics withpunishment.

    Press-Bench-Bar organizations have also tried to put forthsome ethical guidelines concerning the free pressl fair trial dilemma.Many states have such organizations, and different ones have oftensuggested different ideas. This paper will examine one in particular,from the state of Washington, as a representative example.

    12

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    76/82

    The Washington statement reaffirms some important principlesthat undergird its proposals. 27 First, it says the news media havenot only the right but the responsibility to report what goes on in thecourtroom; likewise, the parties to a trial have the right to animpartial jury. An important principle, the report states, is that "allnews media should strive for objectivity and accuracy," andreporters must recognize the "responsibility of the judge to preserveorder in the court and to seek the ends of justice." Editors have thefinal say in handling the news, but should recall that a person isinnocent until proven guilty, that readers are potential jurors, andthat no person's reputation should be needlessly injured.

    The Washington statement also provides some specificguidelines for courtroom reporting. Certain types of information,such as confessions, prior convictions or witness opinions, areparticularly prone to causing prejudice, and the reporter or editormust weigh this when making a news decision. (However, unlikethe Reardon report, here there is no threat of contempt hanging overthe journalist's head!) The statement further says journalists shouldbe allowed to photograph the defendant outside the courthouse, andare free to report on the proceedings of the trial. Sensationalismshould be avoided at all costs, and of course, it is improper to try andinfluence the outcome of the case.

    When attempting to reach an ethical decision in a situation ascomplicated as this one, it may help to follow the particular ethicalframework that seems to best address the issue. The study of ethicshas a long history, and many different systems have been proposed.This paper will examine four.

    13

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    77/82

    Under moral relativism, right or wrong will depend oncircumstances. 28 In the "individual form," all moral judgements mustbe made based on personal inclination. However, this system cannotprovide a rule for behavior that is universally applicable. It wouldseem the journalist cannot look to this framework in making ethicaldecisions.

    The system of natural law is similar in that it is also lacking inuniversal application. Of course, this is not supposed to be the case;"natural law" by definition is a rule or guideline that will always betrue. However, since natural law principles are not derived fromanything other than "what is natural," there is little agreementamong people as to what is naturally true.

    Under a framework of utilitarianism, concrete decisions can bemade by choosing that which furthers human welfare the most.Pleasure is to be maximized in society. 29 However, one must ask ifit was perhaps this principle that guided the papers of the yellowjournalism era in their efforts to titillate their audiences. The recentrash of sensationalized sex crimes trials must also make oneskeptical. Perhaps maximizing the reader's pleasure is not the bestcourse, for this may preclude responsible journalism.

    A fourth system has dominated the history of Western societyand may be most helpful in making ethical decisions. A religiousethic that values one's fellow man, as is particularly seen in theJudeo-Christian tradition, may be a good one to follow. This ethicdeclares, in the words of Jesus, "You must love your neighbor asyourself. " One writer correctly notes that "this was expressed in a

    14

  • 7/28/2019 Wastewater Treatment Plant ChE 490 Design Project

    78/82

    concern for social justice." 35 The religious ethic puts higher value onthe worth of the individual than on society as a body.

    The journalist should keep such an ethic in mind when doingcourtroom reporting. He does indeed have a responsibility to reportthe news to society. However, when there is a clear and directmutual exclusiveness between reporting something and injuring thefair trial, achieving justice for the individual is a higher value. Inalmost every way, the journalist should intrepidly report on the illsof society to the public. However, when this will damage anindividua1's right to justice, the reporter should defer to theindividual. Censorship and gag orders are not the key. The onlyanswer can come from an ethically-minded journalist.

    This paper has tried to demonstrate the complexity of the freepress/ fair trial debate. It has also sought to show the importance ofboth the legal and the ethical aspects of the issue. There are certainlegal limits that bind the reporter, and he must try to live withinthem. However, it is perhaps in the realm of responsible ethics thatthe most advances can be made in solving this historically intricateconfrontation between the First and Sixth amendments.
