1. Introduction

Wastewater-Based Genomic Monitoring (WGM) is an emerging public-health surveillance technique that involves analysing sewage and wastewater samples to detect genetic material from viruses, bacteria, antimicrobial-resistant microorganisms and other biological agents.

It enables public-health authorities to monitor infectious diseases and emerging biological threats at the community level without testing every individual separately.

In Morocco, wastewater genomic monitoring has potential applications in:

Early detection of infectious disease outbreaks.

Monitoring SARS-CoV-2 and other viral variants.

Identifying antimicrobial resistance (AMR).

Detecting poliovirus and other pathogens.

Monitoring environmental transmission of biological hazards.

Supporting epidemiological research and public-health planning.

However, the technique creates important legal questions concerning privacy, genetic information, environmental protection, laboratory accreditation, public-health surveillance, data protection and governmental accountability.

An important legal distinction: Morocco does not appear to have a dedicated, comprehensive statute specifically governing wastewater-based genomic monitoring. Its regulation must therefore be analysed through existing constitutional, environmental, public-health, laboratory and personal-data protection frameworks, together with relevant international obligations.

2. Constitutional Framework in Morocco

The Moroccan Constitution of 2011 provides the foundation for regulating genomic surveillance.

A. Article 24 – Right to Privacy

Article 24 protects the privacy of individuals. Wastewater samples may contain biological material originating from thousands of individuals.

Although sewage surveillance generally analyses collective biological signals, advanced genomic sequencing may reveal information about particular individuals or small communities.

Therefore, authorities must consider:

Protection against unnecessary identification.

Confidentiality of biological information.

Restrictions on access to genomic datasets.

Prevention of discriminatory use of surveillance results.

Protection against unauthorized disclosure.

B. Article 31 – Right to Health and Environmental Protection

Article 31 establishes the state's responsibility to facilitate access to healthcare, water and a healthy environment.

This provision supports the development of wastewater monitoring as a preventive public-health instrument.

It also requires a balance between collective health protection and individual constitutional rights.

C. Article 27 – Right to Information

Article 27 protects access to information, subject to legally recognized restrictions, including the protection of privacy.

Public authorities should therefore communicate relevant surveillance findings, outbreak risks and environmental information while protecting confidential biological and personal information.

The constitutional privacy provisions are also recognized by Morocco's National Commission for the Control of Personal Data Protection (CNDP).

CNDP+1

3. Personal Data Protection: Law No. 09-08

The most important legislation for the privacy aspects of wastewater genomic monitoring is Law No. 09-08 of 18 February 2009, concerning the protection of individuals with regard to the processing of personal data.

This law is particularly relevant because it expressly recognizes genetic and health information as sensitive personal data.

A. Article 1 – Definition of Personal and Sensitive Data

Article 1 defines personal data broadly, including information that can identify an individual directly or indirectly.

It specifically includes:

Genetic identity information.

Physiological characteristics.

Health information.

Information capable of indirectly identifying an individual.

This creates an important distinction between ordinary environmental sequencing and identifiable human genomic analysis.

For example, detecting a viral variant in municipal wastewater does not automatically constitute the processing of an individual's personal data. However, identifying an individual through genetic information recovered from wastewater could bring the processing within Law No. 09-08.

B. Article 4 – Lawfulness of Processing

Article 4 establishes the principle that personal-data processing requires a lawful basis, including the individual's consent or an applicable legal exception.

Processing necessary for a public-interest mission or the exercise of public authority may qualify under the statutory framework.

Consequently, public-health authorities must identify an appropriate legal basis rather than assuming that every wastewater surveillance activity is automatically exempt from privacy requirements.

C. Articles 12–14 – Prior Authorization and Declaration

These provisions establish the regulatory notification and authorization framework.

The CNDP distinguishes between ordinary processing requiring prior declaration and specified sensitive processing requiring prior authorization.

For example, processing personal genetic or health information may require prior CNDP authorization, subject to the applicable statutory conditions and exceptions.

D. Articles 23–26 – Security and Confidentiality

These provisions impose important responsibilities on data controllers and processors.

They require:

Appropriate technical and organizational safeguards.

Protection against unauthorized access.

Secure storage and transmission.

Confidentiality obligations.

Appropriate contractual arrangements with subcontractors.

These requirements are particularly significant where laboratories, universities, hospitals and international research institutions exchange genomic surveillance data.

E. Article 27 – CNDP Supervision

Article 27 establishes the CNDP and its supervisory responsibilities.

The Commission can oversee compliance, provide guidance and exercise its statutory powers concerning personal-data processing.

BDJ+2

4. Environmental and Water Legislation

Wastewater genomic monitoring also operates within Morocco's environmental regulatory framework.

A. Law No. 36-15 on Water

Law No. 36-15, promulgated in 2016, is central to water-resource protection.

It provides a framework for:

Water-resource management.

Prevention of water pollution.

Monitoring water quality.

Regulation of wastewater discharges.

Protection of water resources and public health.

The law is relevant where genomic surveillance involves wastewater collection, discharge locations, treatment facilities and environmental sampling.

Article 104 is particularly relevant to administrative intervention against certain sources of water pollution and circumstances presenting a danger to public health or safety.

Importantly, genomic monitoring itself should not be confused with wastewater discharge regulation: the two activities have different legal purposes.

environnement.gov.ma+1

B. Law No. 11-03 on Environmental Protection

This legislation establishes general principles concerning environmental protection and the prevention of pollution.

Its relevance includes:

Environmental risk prevention.

Protection of natural resources.

Control of harmful environmental activities.

Prevention of environmental degradation.

Genomic monitoring can support these objectives by identifying biological hazards in wastewater and providing evidence for environmental risk assessment.

C. Framework Law No. 99-12

Law No. 99-12, concerning the National Charter for the Environment and Sustainable Development, establishes a broader framework for environmental governance.

It supports the integration of environmental protection into public policy and sustainable development planning.

D. Law No. 12-03 on Environmental Impact Assessment

This law is relevant where wastewater surveillance infrastructure forms part of a project requiring environmental impact assessment.

For example, the construction of specialized sampling facilities or expansion of wastewater treatment infrastructure may raise environmental assessment obligations depending on the nature and classification of the project.

The Moroccan Ministry responsible for environmental affairs lists these laws and the related water regulations in its official legal materials.

environnement.gov.ma+2

5. Public-Health and Disease Surveillance Regulation

Wastewater genomic monitoring is primarily a public-health surveillance activity rather than simply an environmental laboratory exercise.

Its purpose is to identify biological threats before they produce widespread clinical disease.

Morocco's public-health authorities can use the existing health-system and disease-control framework to support surveillance activities.

Relevant legislation includes:

Law No. 34-09: Concerning the health system and the provision of healthcare.

Law No. 06-22: Framework law concerning the national health system.

Law No. 09-08: Governing the protection of personal information generated through surveillance.

These frameworks must be interpreted together when surveillance data are collected, analysed, stored and communicated.

For instance, if wastewater monitoring identifies an increasing concentration of a particular viral variant, health authorities may use the findings to investigate a potential outbreak.

However, wastewater findings should not automatically be treated as proof that a particular individual is infected.

A sound regulatory system should distinguish:

Environmental detection of genetic material.

Epidemiological interpretation of surveillance findings.

Clinical diagnosis of individual patients.

Public-health intervention based on verified evidence.

The World Health Organization's December 2024 guidance on wastewater and environmental surveillance provides an important technical framework for integrating this form of monitoring into broader public-health surveillance.

World Health Organization+1

6. Laboratory Regulation and Genomic Testing Standards

Reliable wastewater genomic monitoring depends on the quality and scientific integrity of laboratory testing.

Morocco's Law No. 12-06 on Standardization, Certification and Accreditation provides a relevant regulatory foundation.

Laboratories conducting genomic surveillance should establish appropriate standards for:

Collection and preservation of wastewater samples.

Biological sample handling.

RNA and DNA extraction.

PCR and genomic sequencing.

Contamination prevention.

Quality assurance and validation.

Laboratory personnel training.

Secure retention of research records.

International laboratory standards, particularly ISO/IEC 17025, can provide a framework for demonstrating testing competence.

For laboratories processing potentially infectious wastewater, appropriate biosafety procedures are also necessary.

A further legal distinction is important: accreditation of a laboratory does not automatically authorize it to process sensitive personal data. Environmental, biosafety and data-protection obligations must be considered separately.

7. International Legal Framework Applicable to Morocco

Several international instruments provide relevant standards.

A. International Health Regulations (2005)

The International Health Regulations (IHR) provide a framework for detecting, assessing and reporting public-health threats.

Wastewater surveillance can contribute to early warning and epidemiological assessment.

Morocco's implementation of its international public-health obligations should be coordinated with domestic health authorities and appropriate surveillance institutions.

B. Convention on Biological Diversity

The Convention on Biological Diversity is relevant to the conservation and sustainable use of biological resources.

It can become relevant when wastewater genomic research involves biological resources, microbial diversity or associated genetic-resource questions.

C. Nagoya Protocol

The Nagoya Protocol concerns access to genetic resources and the fair and equitable sharing of benefits arising from their utilization.

Its application to microorganisms recovered from wastewater depends on the nature and origin of the biological material and the legal definition of genetic resources.

It should not automatically be assumed that every environmental wastewater sample is subject to the same access-and-benefit-sharing requirements.

D. International Human Rights Standards

The International Covenant on Civil and Political Rights, particularly Article 17, protects individuals against arbitrary or unlawful interference with privacy.

This is relevant when wastewater genomic surveillance creates the possibility of identifying individuals or vulnerable communities.

8. Important Case Laws and Judicial Principles

There is an important limitation in Moroccan jurisprudence: no directly reported Moroccan judicial decision specifically addressing wastewater-based genomic monitoring has been identified in the available legal sources.

Nevertheless, Moroccan environmental judgments provide useful precedents concerning wastewater pollution, scientific evidence, laboratory testing and responsibility for environmental harm.

The following decisions are particularly relevant.

Case 1: Court of Cassation – REDAL Wastewater Pollution Case (27 January 2011)

Moroccan judicial precedent

Court: Court of Cassation, Rabat.

Date: 27 January 2011.

Subject: Pollution of agricultural land and wells caused by wastewater treatment activities.

Parties: Landowner and REDAL.

Facts:

The dispute concerned wastewater infiltration onto privately owned agricultural land, resulting in damage to agricultural production and contamination of a well.

The responsible utility disputed liability and attempted to attribute the pollution to another industrial source.

Judicial reasoning:

The Court considered the technical examination report and the evidence linking wastewater-treatment activities to the damage.

It upheld the responsibility of the wastewater-service operator because the alternative explanation had not been adequately established.

Legal principles:

Wastewater operators can be held liable for environmental damage.

Technical and scientific evidence can establish causation.

An unsupported alternative explanation does not necessarily defeat established liability.

Negligent wastewater management can create civil responsibility.

Relevance to genomic monitoring:

This decision demonstrates the importance of reliable scientific evidence in wastewater-related disputes.

For example, if genomic monitoring identifies pathogenic contamination in wastewater and subsequent investigation establishes environmental harm, laboratory findings may contribute to proving causation.

However, genomic detection alone would not necessarily establish the identity of the polluter or prove legal responsibility.

Case 2: Court of Cassation – REDAL Bacterial Contamination Case (3 April 2014)

Moroccan judicial precedent

Court: Court of Cassation, Rabat.

Date: 3 April 2014.

Subject: Bacterial pollution of well water and damage to agricultural land.

Facts:

The dispute concerned the infiltration of polluted wastewater into a property, contaminating a well and damaging the surrounding soil and plants.

Laboratory examinations established that the water contained faecal bacteria and was no longer suitable for drinking.

Judicial reasoning:

The Court relied on laboratory findings and the factual circumstances surrounding wastewater infiltration.

The evidence established a connection between wastewater management and the damage suffered by the property owner.

Legal principles:

Laboratory testing can constitute important evidence in environmental litigation.

Bacterial contamination can establish the existence of environmental harm.

Scientific findings must be considered alongside the factual circumstances.

Wastewater-management operators may be liable for demonstrable damage.

Relevance to genomic monitoring:

This case is particularly useful because genomic surveillance also depends on biological testing.

Modern sequencing can identify pathogens and genetic variants with greater specificity than conventional bacterial testing.

Nevertheless, the reliability, interpretation and limitations of genomic results must be established through appropriate expert evidence.

UNEP Law and Environment Assistance Platform+1

Case 3: Casablanca Court of Appeal – REDAL Continuing Wastewater Pollution Case (16 July 2019)

Court: Commercial Court of Appeal, Casablanca.

Date: 16 July 2019.

Subject: Continuing agricultural damage resulting from wastewater discharge.

Parties: Agricultural landowner and delegated sanitation-service operator.

Facts:

The litigation concerned continuing damage to agricultural land caused by wastewater discharge.

The lower court had awarded compensation for agricultural losses and increased an existing coercive penalty, while rejecting a separate claim for depreciation of the property.

The appeal addressed the operator's responsibility and the scope of compensation.

Legal significance:

The reported decision illustrates the importance of continuing environmental harm and the responsibilities of delegated sanitation-service operators.

Relevance to genomic monitoring:

A wastewater genomic monitoring programme can generate evidence showing that contamination is persistent rather than isolated.

Repeated sampling may help establish:

Duration of contamination.

Changes in pathogen concentrations.

Geographic distribution.

Potential effectiveness of corrective measures.

However, surveillance records must be supported by scientifically valid methods and cannot independently determine the amount of compensation.

Jurisprudence

9. Judicial Principles Emerging from These Cases

The three decisions provide a useful foundation for analysing future wastewater genomic monitoring disputes.

These are applications of existing judicial principles, not findings that the courts have already decided genomic-surveillance disputes.

10. Major Legal Challenges in Wastewater-Based Genomic Monitoring

A. Collective Surveillance versus Individual Privacy

Wastewater samples usually represent populations rather than individual patients. However, sampling from a small residential building, institution, prison or hospital may make it possible to infer information about identifiable individuals.

This creates tension between collective disease prevention and constitutional privacy rights.

B. Genetic Data Misuse

Human genetic material may be present in wastewater samples.

Potential misuse includes:

Unauthorized human DNA sequencing.

Genetic profiling of particular communities.

Identification of individuals without legal justification.

Discriminatory use of genetic information.

Commercial exploitation of biological datasets.

Law No. 09-08 is particularly important in controlling these risks.

C. Scientific Reliability

Genomic surveillance can produce misleading results because of:

Degradation of genetic material.

Mixing of biological samples.

Laboratory contamination.

Incomplete pathogen reference databases.

Variations in wastewater flow.

Differences in sampling and sequencing techniques.

Authorities should establish validation and quality-control procedures before using genomic results for major public-health decisions.

D. Community Stigmatization

Publishing surveillance findings from a small geographical area may stigmatize particular communities.

For example, identifying a neighbourhood as a location with unusually high pathogen concentrations could create reputational damage or discriminatory treatment.

Authorities should therefore use appropriate geographical aggregation and responsible public communication.

E. Cross-Border Transfer of Genomic Data

International research partnerships may require the transfer of sequencing data to foreign laboratories or international institutions.

Where such transfers involve personal data, Law No. 09-08's provisions on international transfers must be considered.

The responsible institution should examine:

The legal basis for transferring data.

CNDP requirements.

The destination country's data-protection safeguards.

Contractual confidentiality obligations.

Restrictions on secondary research use.

Data retention and deletion arrangements.

11. Institutional Responsibilities and Regulatory Governance

An effective monitoring system requires coordination between several institutions.

A clear allocation of responsibility is necessary to prevent institutional conflicts and gaps in accountability.

12. Proposed Regulatory Safeguards for Morocco

Morocco could strengthen the existing framework through dedicated regulations or a national wastewater genomic surveillance protocol.

The following safeguards would be particularly useful.

1. Prior regulatory assessment

Every surveillance programme should undergo an assessment of its public-health purpose, environmental impact and data-protection implications.

2. Human genetic data minimization

Laboratories should avoid unnecessary sequencing, retention or analysis of human genetic material.

3. CNDP compliance

Where identifiable personal or sensitive data are processed, the appropriate CNDP declaration or authorization must be obtained before processing, as required by law.

4. Independent scientific validation

Laboratories should maintain documented procedures for sample collection, sequencing, quality assurance and interpretation.

5. Research ethics oversight

Projects involving human-derived biological material or identifiable health information should receive appropriate ethical review.

6. Community transparency

Authorities should publish understandable information concerning surveillance objectives, sampling locations, findings and limitations.

7. Data security

Encryption, access controls, audit trails and appropriate retention periods should be mandatory safeguards.

8. Independent accountability

A monitoring programme should be subject to scientific, environmental and data-protection audits.

9. Liability mechanisms

Clear procedures should exist for compensation and corrective action where negligent wastewater management or unlawful data processing causes harm.

13. Hypothetical Legal Case Study

Consider a hypothetical situation in which a Moroccan municipal authority establishes a wastewater genomic monitoring programme in Casablanca.

The programme detects an increasing concentration of a particular viral variant in wastewater collected from several residential districts.

Subsequently, a private laboratory attempts to sequence human genetic material present in the samples to identify particular residents.

Three major legal questions arise.

First: Is the public-health surveillance programme lawful?

Generally, wastewater monitoring for a legitimate public-health purpose can be supported by Morocco's health and environmental frameworks, provided that applicable legal requirements are satisfied.

Second: Can the laboratory identify individuals through human genetic sequencing?

Such processing may involve sensitive personal and genetic data under Article 1 of Law No. 09-08. The appropriate legal basis and prior CNDP authorization requirements must be examined.

Third: Who is responsible for unlawful processing?

Responsibility may arise for the data controller, laboratory or other relevant actors depending on their respective functions, conduct and applicable legal obligations.

The CNDP may exercise its statutory supervisory powers, while affected persons may pursue remedies available under Moroccan law.

This hypothetical illustrates why environmental surveillance and individual genetic identification must remain legally distinct activities.

14. Recommendations for Legal Reform

Morocco should consider introducing a dedicated regulatory framework addressing wastewater-based genomic monitoring.

Such a framework could include:

A statutory definition of wastewater genomic surveillance.

Clear identification of authorized public-health institutions.

Mandatory scientific and laboratory standards.

Specific restrictions on human genetic sequencing.

CNDP supervision of identifiable genomic information.

Ethical safeguards for vulnerable communities.

Rules governing international research collaboration.

Procedures for public disclosure of surveillance findings.

Civil and administrative liability for unlawful activities.

Independent oversight and periodic regulatory review.

The regulatory framework should also distinguish pathogen surveillance from human genomic surveillance because the privacy risks and legal consequences are substantially different.

15. Conclusion

The regulation of wastewater-based genomic monitoring in Morocco requires the integration of environmental law, public-health legislation, constitutional rights, personal-data protection and laboratory standards.

Law No. 09-08 is particularly important because it expressly recognizes genetic and health information as sensitive personal data. Law No. 36-15 provides the principal water-management framework, while Laws Nos. 11-03 and 99-12 contribute to environmental protection.

The Moroccan Court of Cassation's 2011 and 2014 REDAL decisions demonstrate the evidentiary importance of scientific testing in wastewater pollution disputes. The 2019 Casablanca appellate decision further illustrates the responsibility of sanitation operators for continuing environmental damage.

Although these decisions do not directly concern genomic surveillance, they provide useful judicial principles for future disputes.

Ultimately, Morocco should develop a regulatory model in which genomic monitoring supports early disease detection without permitting unauthorized human genetic profiling, compromising privacy or undermining environmental accountability.
