Práticas e ações de sustentabilidade com intervenção pedagógica
(Universidade Federal do Pará, 2025-02-06) MIRANDA, Françoise Helouise Costa de; PENNER, Giovanni Chaves; http://lattes.cnpq.br/3110276957027781
There is a worldwide concern regarding climate change, and in order to find a response to thisthreat, several agreements and conferences are being held around the world. The motivation for the project comes from the difficulty that basic education faces in planning sustainable practices and actions in the school environment. In view of this, we thought of providing solutions so that the proposals could be developed by a public elementary school in the city of Belém-Pará, given that this educational system plays an important role in the dissemination of information and innovation. Therefore, we decided to work in 3 stages within the project developed by the school entitled “Schools of Knowledge and Actions for Sustainability”, to recognize the area, analyze the project proposed by the school, search for existing projects, and establish technical partnerships with the objective of raising awareness in the school community about the responsible use of natural resources, such as reducing energy consumption, water consumption, and creating healthier environments for the school community and consequently for the surrounding population. Based on the visits, meetings held with teachers, school management and observation of the infrastructure characteristics, sustainable actions and practices of the aforementioned project were initiated, as well as the use and adaptations of the methodology of the Environmental Agenda in Public Administration - A3P made available by the Ministry of the Environment were proposed, which did not happen because the school management was unable to involve and encourage teachers in the activities that were carried out with the students, resulting in the interruption of the actions.

Proposta de manual técnico para elaboração de um programa de monitoramento da qualidade da água subterrânea no estado do Pará
(Universidade Federal do Pará, 2024-02-09) SIQUEIRA, Maria Roberta Cavalcante de; PENNER, Giovanni Chaves; http://lattes.cnpq.br/3110276957027781; https://orcid.org/0000-0003-0335-5352
Monitoring groundwater is an extremely important activity for diagnosing and controlling potentially polluting activities. Applied to environmental management and control, whether due to a requirement from the regulatory body, through environmental license conditions, it represents a major environmental liability for companies that are not meeting the requirements demanded by these respective regulatory bodies. Activities that can cause changes in groundwater require periodic monitoring to ensure the maintenance of environmental quality, as they are standardized and require standards, manuals and regulations. This respective manual was conducted based on standards from the Brazilian Association of Technical Standards ABNT), international legislation, monitoring manuals and solutions on water quality applicable to the topic, as well as collections made up of monitoring wells within the Campus of the Federal University of Pará, in Belém (experimental area of this research). To this end, disposable Bailer samplers and measurements were used using the low flow system, aiming to define clear guidelines and rules for carrying out the activities involved in the process, as well as commenting on other devices that could be used for collection. of groundwater samples. At the end, a manual of good practices was proposed as a way of ordering and guiding the groundwater monitoring process. It is expected that this proposed technical manual will serve as a reference for groundwater collection, as given the concern within the State of Pará, it is extremely important to organize effective action and forward solutions to this environmental problem. Additionally, this manual is intended to be a purposeful document, and can be useful in environmental monitoring in different polluting activities.

Proposta de monitoramento ambiental do parque estadual do Utinga: uma ferramenta para a melhoria dos serviços prestado a população da região metropolitana de Belém
(Universidade Federal do Pará, 2023-04-27) LIMA, João Batista Marcelo de; PENNER, Giovanni Chaves; http://lattes.cnpq.br/3110276957027781; https://orcid.org/0000-0003-0335-5352
This work was developed in order to present an Instruction Guide, as a subsidy to the conception of the environmental monitoring system proposed for the State Park of Utinga (PEUt), which it was decided to call SISPEUt. In order to make it simpler and, therefore, more likely to be implemented, it was first decided to idealize it for the qualitative investigation of the soil and water in the Park. Initially, a study was carried out to verify the recommendations regarding the installation of a monitoring system for the environmental quality of the PEUt. This stage included the analysis of Brazilian hydro-environmental laws, norms, plans and programs that directly or indirectly presented such recommendations. Next, a survey of the vulnerability of the area was carried out in the face of the advance of the urbanization of the RMB. In this investigation, the threats imposed on the Park and its environmental elements became evident. In order to reveal details about the advantages of an environmental monitoring system, a study of qualitative and quantitative monitoring cases in protected areas in Brazil and abroad was carried out. The results showed benefits for the entire production chain associated with the monitored area, with gains also for the management bodies, for the political, academic and scientific classes, as well as for the general population. From all the survey carried out, the hypothetical-deductive method was used to ratify the objective of this work, which is summarized in presenting the Guide mentioned above. The architecture adopted for the proposed system was guided by the policies and guidelines of the ePING (Electronic Government Interoperability Standards), which advocates the use of public and/or free computer programs in the design of monitoring systems such as SISPEUt. The parameters to be monitored were defined according to norms and hydro-environmental programs in force or in progress in Brazil, with the contribution of systems that monitor environmental variables in the national territory. As for the location of the measurement and sample collection points, these were determined based on the Park's physiography and the threats imposed on the Conservation Unit (UC). In short, the final product of this work is considered an important contribution to environmental management in the RMB, since the implementation of SISPEUt can bring important subsidies to the protection of the CU and, consequently, improve the services provided to the population, especially those related to the provision of water for public supply.

Recarga do aquífero livre na Universidade Federal do Pará, campus Belém
(Universidade Federal do Pará, 2023-02-06) SILVA, Salim Rodrigues da; PENNER, Giovanni Chaves; http://lattes.cnpq.br/3110276957027781
In Brazil urban supply, rural supply, industry, mining, thermoelectric, animal and irrigation consume approximately 61.46 billion m³/year of fresh water, with the greatest demand being urban supply (25%). In Belém, groundwater collection to feed the Water Supply System has been increasing. Despite this, the low quality of its distribution ends up stimulating the capitation of water without any criteria, contributing to the overexploitation of aquifers. In the field of scientific research, in the State of Pará, the amount of work to estimate underground recharge is incipient, making the development of new research urgent. Therefore, this work aims to estimate the recharge of the aquifer free of primary porosity located in an alluvial deposit, underlying the Federal University of Pará (UFPA), Belém campus. The recharge estimate was carried out using the Water-Table Fluctuation (WTF) method in 8 monitoring wells distributed in the so-called health and professional sectors of the Federal University of Pará. The mean water level variation in the study area was between 0.76 and 2.27 m (discrete and continuous monitoring). A specific yield (Sy) was determined through a pumping test, which provided data that were analyzed in the AQTESOLV Demo software, using the Tartakovsky-Neuman analytical solution. The Sy result of the pumping test was 0.1 (10%). The estimated recharge for discrete monitoring was between 101.40 mm and 371.60 mm (year 2020), between 75.50 mm and 552.60 mm (year 2021) and between 19.50 mm and 140.50 mm (year 2022), with an average of 583.51 mm, which represents 6.93% of the precipitation in the study period (8,419.14 mm) and for continuous monitoring, it was between 40.00 mm and 87.90 mm (year 2020) and between 19.30 mm and 218.80 mm (year 2021), with an average of 539.45 mm, which corresponds to 38.86% of the precipitation of the study period (1,338.10 mm). Thus, based on discrete and continuous monitoring data, the average recharge for the study area corresponds to approximately 22.89% of the total precipitation. The results referring to the correlation between water table fluctuation and rainfall showed an average determination coefficient of 22.49%. Both the recharge and the correlation proved to be consistent with the other surveys carried out in Brazil. As explained above, continuous assessment of aquifer recharge is recommended for the sustainable use of groundwater resources, in order to ensure their multiple uses.
